When you first had solar panels installed you probably did not even consider the need to keep them clean.


Unlike windows the panels on your roof need to have a clean and clear surface to ensure they are working at their maximum efficiency. If they are not at their optimum performance it means they are not producing the amount of electricity that they could be.​

On the roof and angled skywards the panels will attract dirt, dust, soot, pollen, tree sap and salt crystals in coastal regions creating a fine layer of grime. This layer reduces the amount of light reaching the silicon cells under the glass surface and reduces the panel's effectiveness. A solar panel that has never been cleaned could be producing almost a third less power than it otherwise could be. Some have reported a ten to fifteen percent loss of solar output due to dirty panels. Boston University in the States have done some research on this and claim that as little as a few grams of dust per square metre can halve their efficiency.


From the ground the panels may appear to be clean, just like your windows. Up close however you can see the grime that has built up from the dirt and pollution in the air. A more noticeable deposit that can be left on panels is bird droppings. These tend to completely block the light from areas of the photovoltaic panel and can considerable reduce its effectiveness.


Some people may try to clean them themselves although this is not recommended. Firstly it can be dangerous trying to reach your roof without the proper equipment. Secondly you may end up damaging the panels either accidentally or by attempting to clean them yourself.


Using standard windows cleaning tools means that they will end up leaving soap residue behind and hard water spots as any water on the panels surface evaporates.


We use a water fed pole system that can reach the panels on your roof from the ground. They will use a pure water system that uses de-ionised water and a soft head brush attachment so as not to damage the panels. No chemical should be used as these can cause damage.


The best way to prove this is to record the amount of power being generated before the panels are cleaned. Get the panels cleaned and then compare the new reading with the ones that you took earlier. It is best to do this on a sunny day where the weather is pretty constant as the sun disappearing behind the clouds intermittently is going to affect the results.
