How often should London homeowners’ clean solar panels?

Solar panels are often low maintenance, however, keeping them clean is important from them to work efficiently and at full power. For homeowners in London, there is a larger risk of pollution build up, dust, pollen and bird droppings which can lead to the solar panels become grimy quickly. Due to the environment, London homeowners will benefit from professional regular cleaning and maintenance of their solar panels at least once or twice a year.

Keeping solar panels clean on an annual basis is often more than enough to keep them working their best. This is because the natural rain can actually help wash away some of the dirt, however, this is not enough for it to remove tough grime like pollution, bird droppings and tree sap. This type of tough dirt can reduce sunlight from reaching the cells and lead them to work inefficiently and reducing their lifespan. London homeowners would require cleaning more than once a year. This is due to the high levels of traffic pollution, railways and industrial areas.

The weather is also a big factor when it comes to the overall efficiency of solar panels. London is more often blessed with more rainy and cloudy days than sunshine, causing dirt and grime to spread faster and settle across the panels. Regular cleaning will help to prevent this build up and help your solar system to work to its full power potential and last longer protects the panels from potential damage.
