Maintenance & Servicing

Your solar panels are installed, but do you know how to maintain their optimal performance for 25-30 years? Regular maintenance and servicing of your photovoltaic installation are essential to maximise your energy production and the return on your investment.

This sub-category brings together all our practical maintenance guides: from cleaning the modules to annual visual inspections and seasonal precautions. Find out how to prepare your panels for autumn and winter, deal with fallen leaves, snow and dirt, and adapt your maintenance routine to the changing seasons.

How often should you clean your panels? Contrary to popular belief, excessive cleaning can damage the anti-reflective layers. Our experts explain when and how to clean depending on your environment (polluted urban areas, countryside, seaside, dusty agricultural areas). Natural rain is often sufficient, but targeted cleaning once or twice a year will optimise production.

How can you diagnose a drop in efficiency? Learn to identify the signs of abnormal deterioration: hot spots, micro-cracks, delamination, cell browning (LID). Our guides teach you visual inspection techniques, how to use monitoring tools to detect faults, and troubleshooting solutions.

Also discover the myths to debunk: do your panels really produce energy on cloudy days? What loss of yield is normal after 10 years? How can you extend the life of your installation beyond the guaranteed 30 years?
