Unfortunately, rainy weather is not enough to keep your solar panels clean. Pollution, snow, dust, dead leaves, rain, moss, bird droppings: solar panels have to endure a lot.
All dirt on solar panels limits the efficiency and lifespan of the panels. A dirty panel can lose up to 25% of its energy capacity in one year. Cleaning your panels is therefore essential and also saves you money.
A thorough cleaning once or twice a year is sufficient, depending on exposure to dirt.
Spring, for example, is the ideal time to have your panels cleaned, so you can make the most of the sun.
Clean solar panels = higher yield!
