Electrum and YADA Energy support the development of renewable energy sources and the decarbonization of industry in the Suwałki Special Economic Zone

A few weeks ago, a comprehensive agreement was signed between the Białystok-based company Electrum (part of the Electrum Group) and YADA Energy Krupa, Burkiet General Partnership. The result of this collaboration will be an energy optimization project at the PADMA facility, located in the Suwałki Special Economic Zone.

Several years ago, the Padma Group began its cooperation with IKEA – the global leader in home furnishings. Today, the Padma Group comprises a team of over one thousand people, consisting of committed specialists and production employees ready to meet ever-growing demands.

“Our primary goal is to deliver the highest quality products at the best prices. Optimizing energy consumption in the production process is a prerequisite for maintaining market competitiveness. A key element of our strategy in this area is the fact that this goal will be achieved through further expansion of renewable energy sources, already coming from our own assets – which is undoubtedly a step toward further decarbonization of Polish industry,” said the Management Board of the Padma Group.

Electrum Ventures, a company within the Electrum Group, will be responsible for the full development of the project up to the “ready to build” stage, while Electrum will be in charge of the turnkey construction of a 3.5 MWp PV farm and the implementation of the EMACS system, Electrum’s proprietary system for managing energy sources and power infrastructure. In this project, EMACS will manage three sources: a 1.6 MWp PV farm, a 2.95 MW cogeneration unit, and the newly built 3.5 MWp PV farm. Currently, the EMACS system already manages over 250 energy facilities in Poland, with a total installed capacity of nearly 700 MW.

“The introduction of innovative RES technologies such as EMACS is a key step toward decarbonizing industry in Poland. Modern energy solutions will not only reduce CO2 emissions but also lower energy costs, supporting sustainable development and environmental protection. Our team’s experience in the construction and operation of large-scale energy facilities allows us to effectively manage complex processes and efficiently utilize resources. These skills are also invaluable in smaller energy optimization projects, where precision and innovation are of utmost importance,” said Michał Świerczyński, Commercial Director at Electrum.

According to the project’s assumptions, the cogeneration unit located at the PADMA facility will cover about 85% of the facility’s energy demand. The newly constructed photovoltaic installation will further significantly reduce energy consumption from the National Power System (KSE). Any surplus energy generated will be fed back into the KSE.

Construction is scheduled for completion in the third quarter of 2025, with the EMACS system implementation set to conclude in the first quarter of 2026.

Further investment plans include expanding the installation with additional PV sources and energy storage systems.

Feedback Culture – How open communication builds a better workplace

What is feedback culture?

We talk about feedback culture when regular giving and receiving of feedback is common in an organization.

It is important that feedback should be given to employees at every level of the organization – from interns to senior managers.

Why does feedback culture build a better workplace?

Motivates development

Knowing how to give feedback and effectively delivering the constructive part of feedback not only highlights potential discrepancies between the actual state and the expectations of a supervisor or coworker, but it can also serve as motivation to take action to address any existing skills gap.

It’s also important to mention unconscious incompetence (a situation where we are unaware of our lack of knowledge – we believe we are doing well and don’t see the need for development in a given area because we don’t realize that our competencies are insufficient). This situation can even occur among experienced managers. When feedback is given regularly, we minimize the likelihood of this happening.

Develops talents

The positive part of feedback highlights strengths, and identifying these allows for the development of areas in which employees have natural aptitudes. As a result, their development is significantly faster, and the work they do becomes more enjoyable.

Increases job satisfaction

After receiving positive feedback, employees feel appreciated and aware that their skills and commitment are recognized by others. As a result, their job satisfaction increases, which contributes to lower turnover within teams.

Creates an atmosphere of openness and mutual respect

Regularly provided feedback becomes a natural part of communication for employees. As a result, communication between employees and their supervisors, as well as among coworkers, becomes more open and based on mutual respect.

Feedback culture graphic

Influences better collaboration within teams

Employees are aware of the expectations set by their managers and coworkers. This makes collaboration within teams easier and more effective. It also helps minimize misunderstandings between colleagues.

Builds trust

Open communication in daily work makes relationships more authentic and based on trust and mutual respect.

Feedback Culture Summary

A feedback culture positively impacts the creation of a better workplace. Regular feedback and open communication allow for effective identification and development of talents, motivate growth, and positively affect collaboration within teams. Keep in mind that implementing a feedback culture takes time and requires a strategic plan to take the necessary actions for its implementation.

Efficiency of Solar Panels – How to Calculate It and What It Depends On?

At Electrum, we build solar farms, and high efficiency of solar panels is one of the key factors influencing the profitability of an investment (alongside installation costs, location, and effective energy management).

But what does it really mean for PV panels to be efficient? How do you calculate their efficiency, what causes performance drops, and under what conditions can efficiency increase? We invite you to read our guide, where we will uncover the secrets of solar panel efficiency.

What is the efficiency of solar panels?

The efficiency of solar panels is a measure of their ability to convert solar energy into electrical energy. It is expressed as the percentage of solar energy reaching the surface of the panel that is converted into usable electricity.

In other words, the efficiency of photovoltaics indicates what portion of the solar energy falling on PV panels is converted into electrical energy. Alternatively, we can refer to it as the effectiveness or performance of photovoltaic modules.

How to calculate it? How to check the efficiency of photovoltaic panels?

To calculate the efficiency of photovoltaics, you can use a simple formula. First, you need to gather the following data:

  • Output power – the amount of electrical energy generated by the panel. For example, a 400 W panel means that under ideal conditions, it can provide a maximum of 400 W of power. When calculating PV panel efficiency, either nominal power (under ideal test conditions) or actual power (measured in real-world conditions) is used.
  • Solar irradiance – the amount of solar energy reaching the Earth’s surface. Under standard test conditions (STC), this is assumed to be 1000 W/m².
  • Panel surface area – the physical area of the photovoltaic panel through which radiation passes.

STC and PTC

Internationally, standardized conditions have been established for measuring the performance of photovoltaic installations.

In the context of photovoltaic panels, the STC (Standard Test Conditions) refers to internationally agreed-upon standard test conditions under which panel efficiency is determined. This allows for the comparison of different panels under identical conditions.

On the other hand, PTC (PVUSA Test Conditions) represents test conditions that aim to account for real-world environmental factors affecting a photovoltaic system’s performance.

Formula for Solar Panel Efficiency

Efficiency expressed as a percentage (%) = (Output Power (W) ÷ (Solar Irradiance (W/m²) × Panel Surface Area (m²))) × 100

For example, if a solar panel has a power output of 550 W, a surface area of 2.6 m² (e.g., a panel measuring approximately 2.2 m × 1.2 m), and solar irradiance of 1000 W/m²:

By applying these values to the formula, we obtain an efficiency of 21.15%.

Installation of Solar Panels at solar power plant in Poland

More Accurate Data and panel monitoring

The efficiency of photovoltaic panels can be verified using specialized monitoring software. One such example is the EMACS energy asset management system, which is designed for both large-scale solar farms and installations with capacities up to 1 MW.

It enables users to:

  • Track real-time energy production from PV panels.
  • Analyze historical performance and efficiency of the panels.
  • Optimize system operation and detect anomalies in photovoltaic installations.

Did You Know?

In large-scale solar farms, labor, wiring, mounting structures, and inverters are partially dependent on the number of installed panels. Using higher-power panels reduces the number of modules needed to achieve a specific capacity, which can lower installation and maintenance costs for a photovoltaic farm.

In what conditions can solar panel efficiency increase? 5 Key Factors

Before discussing efficiency losses, let’s explore situations where solar panel performance can actually improve:

  • Strong sunlight and moderate temperatures – A cool yet sunny day is ideal for high efficiency, as extremely high temperatures increase electrical resistance, which can lower performance.
  • Utilizing light reflection – Bifacial panels can capture reflected light from bright surfaces (such as snow), which can increase energy yield by several or even a dozen percentage points. Light can also reflect off water, a principle used in floating solar farms.
  • Cleaning RES installation – If the panels were dirty, cleaning them can significantly boost energy generation, especially in regions with high dust levels.
  • Wind effect – Solar farms located in windy areas can be more efficient since natural air circulation helps cool down the panels, reducing thermal losses.
  • Using solar trackers – Trackers follow the movement of the sun, allowing energy output to increase by 25–40% compared to fixed-mount panels. Learn more in the article: Electrum to Execute One of Poland’s Largest Photovoltaic Projects Using Solar Trackers

Efficiency of Solar Panels in Winter. Panel Covered with Snow.

Temperature Effect

The concept of the temperature effect is closely related to the efficiency of PV modules. Contrary to intuition, higher temperatures do not mean better performance.

Each panel has a temperature coefficient (e.g., -0.3%/°C to -0.5%/°C), which indicates how much its power decreases for every 1°C increase above 25°C (the standard test temperature – STC).

As a result, solar energy production in winter can be efficient, as lower temperatures help maintain higher panel performance.

Solar panel type comparison – Temperature coefficient and heat resistance

 

Panel Type Temperature Coefficient (Pmpp) Heat Resistance Description
Monocrystalline PERC -0.35%/°C to -0.45%/°C 🟠 Medium Standard PV panels with enhanced PERC technology, improving efficiency and reducing costs.
Monocrystalline N-type (TOPCon, HJT) -0.25%/°C to -0.35%/°C 🟢 High More advanced silicon panel versions, offering better efficiency and longer lifespan.
Bifacial (TOPCon, HJT) -0.26%/°C to -0.35%/°C 🟢 High Dual-sided panels generating energy from both sides, increasing yield by 5–20%.
Amorphous (Thin-Film, CdTe) -0.20%/°C to -0.25%/°C 🟢 Very High Lightweight and flexible thin-film panels, well-suited for hot climates.

 

The choice of solar panel type depends on the installation site. For example, PERC cell technology is a great option if the priority is low cost and good performance in a moderate climate.

When does solar panel efficiency decline and How to handle it?

The loss of efficiency and reduced performance of solar panels can result from:

  • Surface contamination – Dirt and dust reduce the amount of sunlight reaching the panels. Regular cleaning helps maintain efficiency. Read more: PV panel maintenance: The key to extended life and efficiency
  • Overheating – A common issue in hot climates that can lower panel performance.
  • Aging – After 10 years, panel efficiency may decrease. It’s important to check the expected degradation rate from the manufacturer.
  • Shading – Even partial shading from trees, chimneys, antennas, or buildings can significantly reduce system output. This is why a professionally solar power system design is essential.
  • Incorrect panel positioning – Improper tilt angle or wrong orientation can reduce efficiency. Read more: What is the optimal solar panel tilt angle? Poland and the world

Smearing Effect (Mismatch Effect or Hot Spot Effect)

The smearing effect (also known as the “mismatch effect” or “hot spot effect”) is a phenomenon that can occur in photovoltaic installations, leading to a decrease in panel efficiency.

This effect is associated with the uneven performance of individual modules within a single installation, which can result in excessive overheating of certain panels and, in extreme cases, permanent damage.

For this reason, it is crucial to regularly monitor the entire photovoltaic system, allowing for quick detection of underperforming panels, which can then be repaired or replaced efficiently.

Solar Panel Efficiency and Frequently Asked Questions

What is the standard efficiency of solar panels in Poland?

The standard efficiency of solar panels in Poland typically ranges between 15% and 25%, depending on the panel technology.

How does solar panel efficiency change in winter?

In winter, panel efficiency may increase due to lower ambient temperatures, which improve performance. However, reduced sunlight and shorter days mean the total energy production is lower.

What is nominal efficiency vs. actual efficiency?

Nominal efficiency refers to the theoretical efficiency of a panel under Standard Test Conditions (STC).

Actual efficiency is the real-world performance of a panel in a specific location, considering factors such as temperature, sunlight, and tilt angle.

In other words, nominal power is the maximum power output a panel can generate under ideal test conditions (STC). Peak power refers to the highest power output achievable in real-world conditions.

How does the efficiency of polycrystalline panels compare to other types?

The efficiency of polycrystalline panels typically ranges between 15% and 18%, which is lower than that of monocrystalline panels (20–23%). Polycrystalline panels are cheaper but less efficient at converting solar energy.

What is IBC and PERC cell technology?

IBC (Interdigitated Back Contact) cells have all electrical contacts on the back of the cell, increasing efficiency and reducing energy losses.

PERC (Passivated Emitter and Rear Contact) technology involves a special rear layer that improves efficiency by reducing energy loss.

How to prevent solar panel overheating?

To prevent overheating, ensure:

  • Proper ventilation around the panels
  • Installing panels at the correct tilt angle for better airflow
  • Using active or passive cooling systems to maintain optimal temperature

What to do when efficiency decreases?

If efficiency declines, conduct a system inspection to detect damage or dirt accumulation on the panels.

What is the temperature coefficient Pmax?

The temperature coefficient Pmax indicates how much power output drops per degree of temperature increase above 25°C. It typically ranges from -0.3%/°C to -0.5%/°C.

What are NOCT conditions?

NOCT (Nominal Operating Cell Temperature) is the temperature at which a solar cell reaches its nominal power output under real operating conditions, such as: 20°C ambient temperature, 800 W/m² solar radiation and light wind.

This metric helps evaluate panel performance in real-world conditions.

How does solar panel cooling work?

Solar panel cooling involves: ensuring proper airflow around the panels, using active cooling systems (e.g., water or air cooling), applying passive cooling methods like heat-dissipating coatings.

What are amorphous silicon panels?

Amorphous silicon panels are thin-film solar cells with lower efficiency (6–10%), but they are cheaper to produce, flexible, allowing installation on various surfaces (e.g., roofs, vehicles).

What should I know about energy? The basics of understanding energy, its sources, and production

This is one of the key scientific questions concerning our lives. The answer is not simple, but in this text, I will attempt to outline as clearly as possible the essence and significance of energy, some of its sources— including renewable sources — and the way it influences our daily lives.

What is energy, and how do we measure it?

Energy is ubiquitous and essential for the functioning of the universe. We know that it powers everything — from our bodies and biological processes, through natural forces such as wind and waves, to advanced technologies and the light of stars.

Although it takes many different forms—such as mechanical, thermal, chemical, electrical, and nuclear energy —i t all boils down to one fundamental concept: energy is primarily the ability to perform work, which in the language of physics is the result of multiplying force by displacement.

Although this basic definition has been expanded in science, for the purposes of this text, it will suffice.

However, to understand how we measure energy, we must also know about:

Work unit, which is the joule (J), informing us about the amount of energy, work, or heat. 1 J is the work done when a force of 1 newton moves an object by 1 meter in the direction of the force.
Power unit, which is the watt (W), informing us about how much work was done in a unit of time.

💡The device has a power of 1 watt if it performs 1 joule of work in 1 second. Therefore, a 10 W LED bulb consumes 10 joules of energy every second of its operation.

smart grid

Energy in practice

Before I write more about electrical energy, which is the foundation of Electrum’s operations, let’s look at energy through the lens of our everyday experience.

When we consume a meal, the energy from the food breaks down in our body so it can work, performing a range of tasks that make up life.

However, even things that seem lifeless from our perspective store energy. For example, a piece of wood, which we can use to sustain a fire in a campfire, contains chemical energy resulting from the bonds between the atoms that make it up. If these bonds are broken, for instance, by applying heat, the chemical energy is released in the form of fire.

E = mc². What does it mean?

However, energy is not just about motion and heat – there is an even more powerful source of it, hidden within matter itself. Let’s stick with the piece of wood mentioned earlier. Every atom in its structure has a nucleus made up of protons and neutrons, and the energy that holds them together is one of the most powerful forces in the universe. This is nuclear energy.

If we were to break the atomic nuclei in a fission reaction, a huge amount of energy would be released – far greater than in any chemical reaction.

It is this nuclear energy that powers nuclear power plants, where controlled fission reactions release heat, which then turns water into steam, driving turbines that produce electricity (which we will discuss later in the text).

E = mc² – this is one of the most famous formulas in physics, which tells us that energy (E) and mass (m) are actually the same thing, just in different forms. C² is the speed of light squared – an enormous number that shows how much energy is hidden in even a small amount of matter.

However, the conversion of 100% of matter into energy, while theoretically possible, is highly unlikely. In the case of nuclear fuel, only a small percentage of it is converted into energy (which still generates enormous power).

Interestingly, Poland is currently the only country in Central Europe without a nuclear power plant. We only have the research nuclear reactor MARIA in Otwock.

Energy Generation and Energy Industry

Since we’re talking about nuclear reactors, it’s worth taking a look at the entire branch of industry that deals with the production and distribution of electricity and heat: the energy sector. We can divide it into conventional and unconventional energy.

  • Conventional energy – present since the Industrial Revolution in the 19th century, involves generating energy by burning fuels such as coal, lignite, oil, and gas, which are understood here as non-renewable energy sources.
  • Unconventional energy – on the other hand, refers to other methods of obtaining energy from renewable sources such as water, sunlight, wind, heat, or from an alternative source such as nuclear reactions.

An interesting point is the issue of biomass, which is a renewable source, but energy is obtained from it in a conventional manner due to emissions and the way it’s produced.

If you want to learn about how wind energy and solar energy work, you can read our articles:

💡 Let’s return to the unit of power, i.e., 1 watt!

In the context of renewable energy sources, let’s go back to the unit of power mentioned at the beginning – 1 watt, or rather 1 megawatt (MW) – which allows us to evaluate how effectively energy generation technologies work.

For example, a 2 MW wind turbine means that under favorable conditions, it can deliver 2 million joules of energy every second. Similarly, photovoltaic panels convert sunlight into electricity, and their power, measured in megawatts, determines how much energy they can produce over time.

The higher the system’s power, the more energy we can obtain. And today, we know one thing for sure: we need a lot of it. We discussed how the world is entering the era of electricity in an article prepared for World Energy Day 2024.

what is energy

Electricity

We know that electricity can be generated in various ways.

At Electrum, the core of our work is electricity obtained from renewable sources.

Electricity is a form of energy resulting from the movement of electric charges, mainly electrons. It is one of the most versatile and widely used types of energy because it can easily be converted into other forms, such as heat, light, or motion.

So, what exactly is electric current?

Electric current is simply the orderly movement of electrons in a conductor (a specific material, such as copper), usually under the influence of an electric voltage (a potential difference between two points). It can take the form of:

  • Direct current (DC) – where electrons flow in one direction (as in batteries).
  • Alternating current (AC) – where the direction of electron flow changes cyclically (as in electrical outlets).

Electricity can easily be converted into other forms:

  • In a light bulb, it turns into light and heat.
  • In an electric motor, it transforms into mechanical energy (motion).
  • In an electric heater, it changes into heat.

Importantly, electricity itself is not a fuel. Fuel refers to a material or substance that contains energy and can release it through combustion, chemical reactions, or other physical processes. Therefore, energy always comes from some source.

This is why the question is so important: how do we produce energy, and do we do it in a sustainable way?

Renewable energy sources are key in the process of decarbonization and reducing greenhouse gas emissions. But I will discuss that in another article.

Important: Energy never disappears!

An important thing to understand is that energy cannot be destroyed or irreversibly lost – it can only be transferred. Energy in nature never disappears; it just changes form and moves from one place to another. Energy always has to go somewhere.

When we plug a phone into a charger, the electrical energy from the outlet goes through several transformation stages before being used, and then continues its “journey.”

The outlet provides high voltage electricity (e.g., 230V), the charger converts it to a lower voltage (e.g., 5V or 20V) and changes alternating current to direct current.

👉 Volt (V) is the unit of electric voltage, meaning the potential difference between two points in a circuit. The higher the voltage, the greater the force with which electrons are pushed through the conductor. For example, in a home outlet, we have 230V, but phone chargers reduce this voltage to safe levels of 5V or 20V so that it can be used by the device.

…tracking our energy further: the phone receives electrical energy and stores it in the battery as chemical energy. While using the phone, the battery converts the chemical energy back into electrical energy, which powers various components – the light from the screen reaches our eyes and surroundings, and a similar process happens with sound waves and heat. Eventually, all the energy that came from the socket is transformed into heat and radiation that spreads into the surrounding world.

Everything is part of the great energy cycle.

Energy must be conserved.

Summary. Key takeaways about energy

  • Energy is the ability to do work – it powers everything, from living organisms to technology and phenomena in the universe.
  • It does not disappear; it just changes form – according to the law of conservation of energy, it transitions from one form to another, but it never vanishes.
  • We measure energy in joules (J) and power in watts (W) – these units help determine the amount and speed of work being done.
  • Energy sources are divided into renewable and non-renewable – the future depends on how wisely we use the former.
  • Electric energy is not a fuel, but a form of energy – it always comes from some source, and its production can have different impacts on the environment.
  • Electric current is the organized flow of electrons – it can be in the form of direct current (DC) or alternating current (AC), which affects how it is used.
  • Voltage (Volt) determines the force with which the current flows in the circuit – for example, an outlet provides 230V, while a phone charger reduces it to 5V or 20V.

The Balancing Market, Negative Energy Prices, and the Role of O&M in Managing Renewable Energy Facilities – An Interview with Krzysztof Kuc

Climate change brings an urgent need to create a new power system where renewable and zero-emission energy sources play the leading role.

One of the challenges in this process is that modern power grids were not designed for power plants where energy production is unstable. Wind and solar energy sources are highly dependent on weather conditions and time of day.

For the energy system to function uninterruptedly and stably – and thus ensure energy security – it requires constant energy balancing. It’s a time-sensitive process: at any given moment, the system must be balanced so that the amount of energy consumed equals the amount of energy generated.

Two of the mechanisms that play a crucial role in this are the balancing market and negative prices.

We invite you to read the article and interview, which provide a deeper understanding of these mechanisms. 👀

How Does the Polish Power System Work?

The National Power System is a network of interconnected components designed to ensure uninterrupted and continuous electricity supply across the entire country. To achieve this goal, it requires real-time management at all times.

This is managed through various interdependent mechanisms. In simple terms, we can explain it like this: the National Power Dispatch takes the lead, overseeing the transmission network, operated by the Transmission System Operator – Polskie Sieci Elektroenergetyczne (PSE). PSE determines the electricity demand, while Distribution System Operators – such as ENERGA, ENEA, Stoen, TAURON, and PGE – distribute electricity to end users.

For the system to operate flawlessly, precise demand forecasts and a range of market regulations are essential. These mechanisms allow for effective control of electricity intake from producers. This is where factors like the balancing market and negative energy prices come into play, directly influencing the production and consumption of energy from renewable energy facilities.

The Balancing Market

  • The balancing market is a mechanism managed by Polskie Sieci Elektroenergetyczne (PSE).
  • Its primary goal is to balance the supply and demand for electricity, ensuring stability and security of supply within the power system.
  • The balancing market operates independently of contracts established in earlier stages of trading – its purpose is system stability, not energy trading.
  • The balancing market is activated when there is a discrepancy between actual and planned energy production or consumption. In such cases, PSE instructs energy producers to increase or decrease their output.
  • One of the mechanisms that can arise within the balancing market is negative prices.

Negative Prices

Negative prices occur when there is an overproduction of energy in the power system, particularly from renewable sources like solar and wind.

In such situations, system operators must implement mechanisms to balance production and demand. Negative prices arise when energy producers have to pay to feed their energy into the grid because the network cannot absorb the surplus – for example, due to low demand or system limitations.

💡 Negative energy prices are typically recorded during specific hours rather than over extended periods.

Recently, a long three-hour period of negative energy prices was recorded in the market. On September 10, 2024, between 1:00 PM and 3:00 PM, the cost of 1MWh was -50 PLN. A record? Thankfully, not in Poland. The Netherlands holds the lead here, where, on May 28, 2023, between 2:00 PM and 3:00 PM, energy was priced at -400 EUR/MWh (approximately -1847 PLN/MWh).

  • Negative prices are an effective solution during the risk of grid overload, encouraging energy producers to reduce production.
  • They also serve as a stimulus for developing energy storage technologies and implementing flexible solutions that allow for better control of energy production.

For renewable energy facilities, negative prices should not pose a significant challenge for a savvy investor using tools that enable precise control over production and operations. Conventional power plants, on the other hand, may struggle more with negative prices, as they cannot be easily shut down within hours.

But what happens to a renewable energy facility during an hour of negative prices?

Operation & Maintenance (O&M) in Managing Renewable Energy Facilities

  • What role does Operation & Maintenance play in the effective management of renewable energy facilities, such as wind farms and solar farms?
  • What happens when energy production exceeds demand?
  • What tools help respond effectively to changes in energy demand?
  • What tools support keeping a renewable energy facility in optimal condition?

These are the questions we address in an interview with Krzysztof Kuc, Service Manager and head of the Operation & Maintenance team at Electrum Solutions. He oversees the work of skilled dispatchers, engineers, and specialists who monitor facilities generating 2.5 GW of clean energy from wind and solar every day – nearly 15% of the national production from wind and solar power plants above 1 MW.

What Do We Do When Our Renewable Energy Facility Produces Too Much Energy and We Can’t Feed It into the Grid?

Krzysztof Kuc: Unfortunately, we have to curtail generation. The systems used by PSE operators and Distribution System Operators (DSOs) can collect information on the level to which specific connection points in a given node must be limited. The operator issues a curtailment order by sending this information via email and phone.

The inability to feed energy into the grid stems from the need to balance the market. Part of this balancing involves sending forecasts of potential generation to distribution network operators well in advance. In the next step, operators reach out to us [the O&M team] with a dispatch order, instructing us to adjust the production levels of the generating unit accordingly.

So the Farm Isn’t Shut Down Completely?

KK: We try not to shut down farms entirely. If there’s no other option, we proceed with a full shutdown, but our priority is to implement so-called set points that limit the active power of the farm to a technological minimum. This way, the farm continues to operate, albeit at reduced power, allowing for a quicker return to full capacity once the restrictions are lifted.

Restarting a renewable energy facility after a complete shutdown can take several hours, resulting in significant financial and time losses. For this reason, we prefer limiting output to a technological minimum, which enables the farm to keep running with minimal losses.

And What Does the O&M Process Look Like for Shutting Down/Disconnecting a Farm, If It Becomes Necessary?

KK: A farm can be shut down remotely. However, if we shut it down with a breaker, it usually needs to be restarted locally later, because after a certain period (when the UPS batteries discharge), we lose the ability to restart it remotely. In such cases, to bring the facility back into generation, a service team must be sent on-site.

Just like a car battery that drains if the car is left unused for too long?

KK: Exactly. The most common issue is related to UPS systems, which maintain communication and the SCADA system at the farms. But they don’t always have sufficient capacity.

For example, on photovoltaic and wind farms, UPS systems have their own capacity and should maintain communication for a specific period. However, these systems often have several years of operation, and their capacity is not the same as when they were first installed. Over time, their capacity decreases, and environmental conditions, such as unfavorable temperatures or humidity, further deteriorate their condition. A UPS that initially lasted 6 hours might only last 1 hour after a few years. If we don’t restart the facility within that time, we have to send a service team on-site to restore generation.

*UPS (Uninterruptible Power Supply) is an emergency power supply device that ensures continuous energy delivery to the key systems of a farm, even in the event of an external power outage. It maintains the stability and safety of operations.

How is Energy Demand Forecasting Done? What Information Is Available to You?

KK: We receive orders to limit generation to a specific level, usually to zero. These orders are issued by the dispatchers from the Distribution System Operators (DSO) or the Transmission System Operators (TSO). Sometimes, we also receive a schedule of curtailments a day before they are implemented, particularly related to negative prices, but this information comes from the client’s representative.

In terms of energy demand forecasting, long-term forecasting is handled by the operators. They forecast energy demand on a daily, weekly, monthly, and even seasonal scale, developing strategies for determining energy consumption plans – this is called balancing. For example, in the summer, there is higher demand for energy due to air conditioning usage, and in the winter, it increases due to the need for heating.

Operation & Maintenance is Largely About Responding to Current Information?

KK: Yes, exactly. Based on information from the client’s asset management or the operator’s dispatching services, who send us requests to limit active power, adjust reactive power settings, or stop such restrictions—these are the so-called setpoints. All this is done to maintain network parameters, such as voltage, at the appropriate level.

The cooperation instructions specify how much time we have to respond to such requests. Operators also send us letters with information about upcoming curtailments, for example, around holidays. They plan everything in advance and inform us about their needs ahead of time.

Many of the ways Operation & Maintenance operates are developed on the fly, in response to changes in the market, right?

KK: When the market is constantly balancing, Operation & Maintenance has to be flexible. We work all the time. We are in continuous contact with operators, monitor their actions, and manage everything to minimize costs and risks for our clients. Operators have to react quickly when they see energy demand and generation. In situations where there is more energy available than the network can accept to maintain balance, we need to curtail the surplus but also ensure that, in case of a sudden spike in demand, we can quickly restore generation.

Where Do Negative Prices Come From?

KK: Negative prices are a mechanism that allows the market to self-regulate. Transmission or distribution system operators sometimes face challenges when issuing dispatch orders. It doesn’t always work immediately, and due to the complexity of the energy system, the orders are not direct.

PSE (Polskie Sieci Elektroenergetyczne) sends production reduction orders to OSD (Distribution System Operators), who then pass them on to us, because we are the ones who oversee operations and carry out operational activities. In some cases, we receive orders directly from PSE if the farm we manage is connected to PSE’s infrastructure.

Negative prices are introduced when there is a forecasted surplus of energy. Operators find it unprofitable to take in this energy, so they should limit generation. This mechanism forces energy producers to self-limit, as no one wants to produce if they have to pay for it. As a result, those managing renewable energy assets analyze the situation and send us restriction schedules.

We do this not only considering financial benefits or losses but primarily with energy stability and security in mind.

Does this mean we’re producing too much green energy, which we’re losing? How does this work in practice?

KK: Often, we produce more energy than our system can absorb. There’s also the issue of infrastructure. During peak production, we might generate more energy than we need, but we don’t have an adequately developed transmission network to send that energy where it’s needed. For example, in May this year, many farms had to curtail energy production because we couldn’t use it effectively. Our infrastructure needs upgrading to efficiently transmit large amounts of energy from one region to another. Where there was too much energy, we had to limit it, and in places where it was needed, the system couldn’t deliver it.

So, what’s next?

KK: One of the solutions will be energy storage systems. We’re talking about battery storage, but also other types of storage, such as heat storage or hydrogen storage. With these systems, managing energy during peak hours, especially with negative prices, will be completely different, as the energy can simply be stored. Various technologies can help improve the management of energy surpluses. Of course, they won’t solve the problem 100%, but they can significantly reduce it. Biogas plants, energy storage systems, and heat storage — all of these should create an energy mix that must be managed effectively. It’s also important to forecast, predict, and properly maintain the infrastructure to respond effectively to changing energy needs. All technologies must work together within a single energy system.

At Electrum, we strive to ensure that these technologies are well integrated, and that managing this energy mix is as efficient as possible. This allows us to achieve the best results.

Read more: How energy storage systems revolutionize RES Market?

We’re talking about solutions outside of systemic investments in national infrastructure.

KK: We have a certain area of action where we can do something and maximize our capabilities, but at the same time, we do face systemic issues related to national infrastructure. We can’t avoid the fact that our transmission networks are insufficiently developed. Investments in infrastructure are necessary, but they can’t be expedited easily. These investments take a long time and cost a lot of money. Therefore, while developing infrastructure, we must also make the most of alternatives, such as energy storage and other technologies, to manage energy surpluses as efficiently as possible and ensure that the system operates as effectively as possible, including on the production management side.

Read more: Energy Project Management: The Key to Success

So, what tools in Operation & Maintenance are crucial?

KK: The key tools are various SCADA systems* and broadly understood forecasting. When it comes to forecasting, based on weather predictions — whether it’s windy or sunny — for a given location, it’s possible to determine what the expected generation should be. The appropriate data, once analyzed and processed, provide information about the generation expected from a particular source or asset for the following day. This information is then sent forward. In our dispatch center, upon receiving information about the required production, whether from the operator or the client, we use SCADA systems to apply restrictions and ensure that they are set in time and at the right level.

*SCADA (Supervisory Control and Data Acquisition) is a system that supervises and collects data in real time, enabling the monitoring and remote control of industrial processes, such as the operation of wind farms, photovoltaic farms, or power plants.

One of these systems is EMACS.

KK: Yes, it is proprietary software developed by Electrum, which offers a wide range of functionalities and improvements for asset managers and O&M operations. There is no other system on the market that provides such extensive capabilities, starting from the engineering side to managing assets and their operations. However, not all assets we manage have EMACS implemented, but this doesn’t pose any problem for us. A significant portion of the assets we handle already had a SCADA system installed earlier. In such cases, we integrate and deploy our system within our control center and train our team to use it. Not every system works the same way; some provide comprehensive information, while others may present certain issues more superficially, such as alarms or changes in the status of devices. In such cases, operators need to be more proactive in detecting irregularities or changes, which could ultimately lead to higher costs or losses for the client, for example, related to reactive power or energy dispatching.

What are the key operational and maintenance challenges for the farms you manage?

KK: The main challenge is keeping the facility in the best possible condition to ensure uninterrupted energy production. This is important both from a financial and ecological perspective. The longer the facility operates without issues, the greater its contribution to delivering green energy. Redispatching and negative prices introduce additional risks, especially when equipment is frequently turned on and off. These operations impact the lifespan of the equipment. For both wind and photovoltaic farms, turning devices on and off means additional wear, which affects their life cycle.

What about inspections? How often are they planned?

KK: Inspections should take place once a year. This is the minimum to check all equipment and ensure that everything is functioning correctly. It’s best to schedule inspections during periods of lowest generation to minimize losses. For wind farms, this is usually in the summer, while for photovoltaic farms, it’s typically after the peak sunshine season, such as late autumn.

Which tools help Electrum maintain its facilities?

KK: We have, for example, a measurement van that allows for quick and precise diagnostics of medium-voltage lines, which are the most prone to failure. With this tool, we can accurately assess the condition of the lines and plan preventive actions. It’s about detecting potential issues before they become major problems – early diagnosis enables us to plan repairs at a convenient time, which is much less costly than responding to failures. This helps avoid long downtimes and expensive repairs.

We also have a wide range of tools, including handheld thermal cameras, which allow for quick diagnostics of issues on an operating facility. Additionally, we have equipment for electroluminescence measurements, which helps assess the condition of photovoltaic panels. This is a very precise tool that shows whether there are internal cracks in the panels, which can lead to damage and, ultimately, reduced efficiency.

How do these actions translate into environmental and financial benefits?

KK: The better we manage a facility, the lower the maintenance costs and the higher its efficiency. By optimizing the operations of the farms, we also reduce the risk of energy generation interruptions, which allows for a fuller utilization of the potential of renewable sources. Ultimately, this approach supports the stability of the power system and brings us closer to a more sustainable future—based on technology, efficiency, and environmental care.

What is the optimal solar panel tilt angle? Poland and the world

Let’s start with a short answer to the question posed in the title. The optimal solar panel tilt angle is the one that allows for capturing the maximum amount of sunlight throughout the year.

In this article, we will:

  • Explore the range of possible tilt angles for solar panels.
  • Analyze key factors that influence the choice of the optimal tilt angle.
  • Discuss revolutionary solar tracking technology.
  • Share useful links with additional resources on designing and building photovoltaic systems.
  • Explain how solar panel direction and angle affect efficiency and energy production.

Solar Panel Tilt Angle: Let’s Explore the Possible Options

Photovoltaic panels can be set at the following angles:

0° Angle (Flat Roofs)

  • This is a method of installing photovoltaic systems on flat roofs of buildings, although it is not very commonly used.
  • In this case, sunlight hits the panels at a sharp angle, especially in the morning and afternoon, which reduces the amount of energy they can capture.
  • This angle is not used for ground installations— the appropriate solar panel tilt angle for ground-mounted systems is greater to facilitate rainwater drainage and minimize shading.

Solar panel tilt angle on a flat roof.

Tilt Angles: So-Called Low Angles of About 10° to 20° (Climate of Andalusia)

  • This tilt angle for photovoltaic modules is most common in countries with a warm climate, where the sun is high in the sky for most of the year (e.g., southern Spain, Greece, United Arab Emirates).
  • Lower angles can help with better cooling of the panels, which increases their efficiency—this is significant in regions with high temperatures.
  • A low solar panel tilt angle may be desirable in areas where strong winds occur; a panel tilted this way has a smaller surface directly exposed to the wind.

The Ideal Solar Panel Tilt Angle in Poland: An Average Angle of About 30° to 40°

  • This angle allows for good energy production throughout the year in Poland and regions with a similar climate—providing a good balance between energy production in summer and winter.
  • The ideal solar panel tilt angle is always dependent on local conditions, so we cannot assume one perfect option for all locations in Poland.
  • In winter, this tilt angle for photovoltaic panels helps with natural cleaning of snow and debris.

Innovations: Adjusting the Tilt Angle of Solar Panels

In the case of more advanced photovoltaic installations, solar tracking systems can be used to automatically adjust the tilt angle of the panels throughout the day to maximize exposure to the sun.

 

At Electrum, we implement such projects. Read more about it:

Another Innovative Project Completed by Electrum – PV Kotuń with Solar Tracker Technology

 

How do solar trackers work?

Solar trackers allow for adjusting the tilt angle of the panels. With their help, it is possible to significantly increase the efficiency of photovoltaic panels and energy production.

Solar trackers follow the movement of the sun in the sky, adjusting the tilt angle of the panels in real time. They can rotate the panels both horizontally and vertically, allowing for optimal positioning throughout the day.

High Angle of About 50° to 60° (e.g., Scandinavian Countries)

  • This panel positioning is used in areas with low sunlight or to maximize efficiency in winter.
  • It is the optimal tilt angle for photovoltaic panels in many mountainous regions with a cool climate and where the sun shines low on the horizon during the winter months.
  • A high tilt angle for photovoltaic panels allows for easier snow sliding and water drainage.

Photovoltaic panels set at an angle greater than 40 degrees. Scandinavian countries.

90° Angle (Vertical Installations)

  • This is a rarely used solution that can be found in architectural installations where panels are mounted vertically.
  • It provides the opportunity to collect light in specific conditions, such as on building facades.

Choosing the best solar panel tilt angle: Location and Season

A detailed answer to the question of what is the best tilt angle for photovoltaic panels depends on several key factors.

During the design phase of a photovoltaic installation, we analyze all relevant factors and adjust the tilt angle of the panels to the specific project.

 

If you want to know more about designing photovoltaic farms, read:

Solar power system design

 

The analysis includes, among other things:

  • Location of the photovoltaic installation – geographical latitude, which affects the position of the sun in the sky (Also read: How to Choose the Best Location for Solar Panels?),
  • Season – the efficiency of the panels in winter can be increased by modifying the tilt angles of the modules,
  • Type of structure – depending on the installation method (on a roof, on the ground, on a frame structure), the ideal tilt angle of the panels may vary,
  • Purpose of the PV installation – if the photovoltaic system aims to maximize energy production in summer or winter, the tilt angle can be adjusted accordingly,
  • Shading – if there are tall buildings, trees, or other obstacles nearby, the tilt angle can be adjusted to avoid shading the panels.

Another Important Matter: Solar panel direction

Solar panel direction, or in other words, the orientation of the photovoltaic panels, refers to the direction in which the panels are set concerning the horizon.

The orientation of solar photovoltaic panels, like the tilt angle, is crucial for maximizing energy production from the installation.

Southern direction

Panels facing south are a common solution in the Northern Hemisphere (including Poland). They provide the greatest exposure to sunlight throughout the day, resulting in higher energy production.

Eastern and Western direction

If southern orientation is not possible, eastern or western orientation can also be effective. Panels facing east will produce the most energy in the morning, while panels facing west will be more efficient in the afternoon.

Northern direction

In countries located closer to the equator, where the sun is high in the sky, northern orientation may be used (for example, to avoid overheating of the panels).

However, this type of module orientation is not a standard solution.

What is the best solar panel tilt angle? Summary

Finding the optimal solar panel tilt angle is a key element in designing an installation. The angle of sunlight incidence varies across different regions of the world, and adjusting the tilt of the panels and selecting the angle allows for optimizing the performance of a photovoltaic power plant.

The possible tilt angle of the panels ranges from 0° to 90°. The optimal tilt value for panels in Poland usually ranges from 30° to 40°. Proper positioning increases the efficiency of photovoltaic panels and, consequently, your profits.
