Solar energy

Welcome to the sunny side​

The sun’s power as a source of clean energy: Without the sun there would be no life on our planet. The amount of energy it radiates is unimaginable. Here on earth, at a distance of 150 million kilometres, we receive more than 1,300 watts of radiated power per square metre. That means it’s up to us to make use of this huge potential.

RWE operates large scale solar projects with a focus on sustainability and innovative solutions for day-to-day operations. In Spain, RWE has currently 6 solar parks in operations with more than 250 MW total capacity.

Operating a solar farm

Operation and maintenance (O&M) of solar plants is essential to ensure their efficiency and extend their lifespan. This process encompasses a range of activities that guarantee the optimal performance of photovoltaic installations, minimising interruptions and maximising energy production.

Key activities in the operation and maintenance of solar plants:

  • Inspection and monitoring.
    Regular inspections are conducted to verify the condition of solar panels and other system components. Continuous monitoring allows for the quick and efficient detection and resolution of issues.

  • Panel cleaning.
    The accumulation of dust and dirt can reduce the efficiency of solar panels. Regular cleaning is crucial to maintain their optimal performance.

  • Preventive maintenance.
    This includes the review and adjustment of all system components, such as inverters, support structures, and control systems. This helps prevent failures and maintain system efficiency.

  • Corrective maintenance.
    In the event of breakdowns, quick and effective repairs are carried out to minimise downtime and ensure the continuity of energy production.

  • Vegetation control.
    Maintaining vegetation around solar panels is important to avoid shadows that can affect energy production and to reduce the risk of fires.
