Renewable energy sources (RES) are a key element in combating climate change and meeting the growing demand for electricity. However, to realize the full potential of RES, it is not enough just to install more photovoltaic (PV) panels and wind turbines. They also need to be properly operated and maintained.

Wind farm maintenance

Wind farms consist of a number of wind turbines that convert wind energy into electricity. Wind turbines are exposed to a variety of weather conditions, such as wind, rain, snow, hail, ice or dust. These factors can affect the performance and life of the turbines, so it is important to check and repair them regularly. Some of the most common problems faced by wind farms are:

• Blade damage: damaged blades can reduce the output of the turbines, increase noise and vibration and even pose a risk to people and the environment. Therefore, the condition of the blades should be checked regularly, appropriate protective coatings applied and repairs or replacements carried out as necessary.
• Generator failure: the generator is the part of wind turbines that converts the mechanical energy of the rotor into electrical energy. The generator can fail due to overheating, short-circuit, bearing damage, contamination or wear and tear. Failure of the generator can cause an interruption of the energy supply, damage to other components or a fire. Therefore, the generator’s operating parameters such as temperature, voltage, current and resistance should be monitored and appropriate preventive and corrective measures applied.
• Electrical and electronic faults: wind turbines are equipped with various electrical and electronic components. These components are susceptible to damage or failure due to surges, overloads, interference, moisture, corrosion or ageing. Electrical and electronic faults can cause grid instability, loss of power quality, loss of data or control and even explosions or fires. Therefore, it is important to regularly check the condition and function of electrical and electronic components, use appropriate protection and filtration, and carry out repairs or replacements as necessary.

Operation of photovoltaic farms

Photovoltaic (PV) farms are one of the most popular sources of renewable energy (RES) in the world. To ensure their high efficiency and reliability, regular and professional servicing of PV farms is necessary. The servicing of photovoltaic farms consists of a number of activities, such as:

• Checking the technical condition of PV modules, inverters, cables and electrical protection.
• Cleaning PV modules from dust, dirt, snow and other contaminants that can reduce their efficiency.
• Detecting and rectifying faults, failures and malfunctions that can cause power drops, fires or risks to people and the environment.
• Monitoring and optimizing PV farm operating parameters such as voltage, current, power, temperature and humidity.
• Measuring and analyzing the performance and quality of the energy produced by the PV farm.
• Complying with safety, environmental and grid standards and regulations.

Servicing PV farms requires the right equipment, knowledge and experience. It is therefore advisable to outsource these services to specialist companies with qualified personnel, certificates and insurance. This is the only way to ensure that RES equipment is serviced efficiently and that its many benefits are enjoyed.

A SCADA (Supervisory Control and Data Acquisition) system is a supervisory and data acquisition system that enables remote control and monitoring of process equipment and processes. A SCADA system consists of three main components: a master station, slave stations and communications. The master station is a central computer that collects and processes data from slave stations, issues control commands and presents information to the operator. Slave stations are field devices such as sensors, transducers, meters, regulators, relays, etc., which perform local measurements and control. Connectivity is the data transmission channel between the master station and the slave stations, which can be implemented through various technologies such as wired networks, wireless, radio, satellite, etc.

The SCADA system is used in a wide range of industries and sectors, such as energy, water supply, transport, telecommunications, industry, etc. In particular, the SCADA system is an essential tool for managing wind and solar farms, which are key sources of renewable energy (RES).

Wind and solar farms consist of many distributed devices, such as wind turbines, photovoltaic panels, inverters, transformers, etc., which must be constantly monitored and controlled to ensure their optimal operation, efficiency and reliability. A SCADA system allows remote access to data and operating parameters of RES equipment, such as power, voltage, current, temperature, wind speed, insolation, etc., and the detection and diagnosis of failures, faults and anomalies. The SCADA system also allows optimisation of energy production and consumption, resource and cost management, forecasting and planning, as well as integration with other systems such as energy management systems, information systems, alarm systems, etc.

The management of RES devices by means of a SCADA system has a significant impact on the profitability of investments in wind and solar farms. By monitoring RES equipment, it is possible to increase the lifespan of the equipment, improve the quality and reliability of the energy supply, reduce operating and maintenance costs, and increase the safety of personnel and the environment. In addition, the SCADA system enables adaptation to changing market and regulatory conditions, such as energy prices, tariffs, taxes, subsidies, emission standards, etc., and the exploitation of opportunities to generate additional revenues, such as system services, energy trading, green certificates, etc.

The combination of the advantages of a traditional SCADA system with a business analysis component can be found in EMACS. This is because the EMACS system combines the advantages of a classic SCADA system with business analysis functionalities such as production and energy consumption optimisation, forecasting and planning, integration with other systems, etc. The EMACS system is the first and only such a multifunctional platform on the Polish market, designed mainly for the energy industry, industry and life science solutions. The EMACS system is an in-house solution from Electrum Solutions, which specialises in creating innovative and technologically advanced services for the RES sector. 

In summary, the SCADA system is a comprehensive solution for monitoring solar and wind farms, which are important sources of renewable energy. The SCADA system provides efficient and flexible management of RES equipment, which translates into increased profitability of investments in wind and solar farms.

Photovoltaic (PV) panels are one of the most popular and environmentally friendly sources of renewable energy. According to the International Renewable Energy Agency (IRENA), the installed capacity of PV panels worldwide reached over 700 GW in 2020, and is expected to grow to over 1500 GW by 2030. However, for PV panels to effectively contribute to green energy production, proper maintenance and servicing are essential.

PV Panel Maintenance – What Does It Involve?

Maintaining PV panels extends their lifespan, which depends on material quality, weather conditions, and operational factors. Regular maintenance helps detect and fix issues, potentially extending the lifespan of panels by up to 10 years.

Safety

Additionally, maintaining solar panels ensures safety for both users and the environment. Malfunctioning or damaged PV panels can pose fire, electrical, or mechanical hazards, and may emit harmful substances into the atmosphere or soil. Therefore, PV panel maintenance should be performed by qualified and certified specialists.

Preventing Financial Losses

Faulty or damaged PV panels can lead to reduced energy production, and even fires or electric shocks. Regular maintenance helps prevent such issues, enhancing safety and cost savings.

PV panel maintenance: Summary

Maintaining solar panels is a crucial aspect of managing PV farms. In other words, it involves managing PV panel arrays installed over large areas that supply energy to the grid or local consumers. Managing PV farms requires not only monitoring and keeping PV panels in good condition but also optimizing their performance, costs, and profits, as well as minimizing their environmental impact. PV farm management is a complex and multi-dimensional process that demands advanced tools and methods.
