Why is solar panel maintenance so important?

Whether they are on the roof of your home, on a commercial building or on the ground, solar panels face weather, dust, bird droppings and sometimes even minor damage every day. Without regular maintenance, this can lead to yield loss and even permanent damage. Think of 'hotspots', places where dirt builds up and can cause local overheating.

Maintenance checks also help you detect any defects early. This prevents small problems from turning into costly repairs. If you schedule solar panel maintenance regularly, the quality of your system stays high and you can count on stable energy yields.

How often is maintenance needed?

The ideal frequency depends on several factors, such as location and the surroundings. In densely built-up urban areas or along busy roads, fine dust can soil the panels faster. If you live in a rural area, pollen and fertilisers may play a role.

In general, you can think of a maintenance check once a year or once every two years. In exceptional circumstances, such as a severe storm or a prolonged heatwave, it is wise to consider an extra check.

How does Solarco work?

  1. 1

    Thorough inspection

    During solar panel maintenance, we take a close look at the entire installation. We check the panels themselves for cracks, discolouration or other signs of wear. We also look at the cabling, the fixings and the inverter, to make sure everything is still working optimally.

  2. 2

    Professional cleaning

    Cleaning the panels is an important part of maintenance. For this we use pure water and robotic cleaners, so we don't need any chemicals. This method removes dirt and deposits while keeping your panels scratch-free. A clean panel surface immediately improves light transmission and energy production.

  3. 3

    Report and advice

    After the inspection and cleaning, you receive a clear report with our findings. We also advise you on any follow-up steps, such as replacing parts or extra checks. That way you know exactly what the status of your installation is and how to keep it in top condition.

All frequently asked questions
Can I maintain my solar panels myself?

You can do simple checks, such as looking for visible damage. For a thorough inspection and cleaning, however, professional help is safer and more effective.

It depends on your location and how dirty the panels get. If in doubt, contact us for expert, tailor-made advice.

Is the inverter also checked?

Yes, we include the inverter in maintenance as standard. We look at temperature, fault codes and general operation, so you can be sure it is working properly.

What if I find damage between maintenance visits?
