"Photovoltaic solar panels are relatively new in the UK in any number. In North America, Europe and Australia as well as many other parts of the world photovoltaic solar systems have been installed for many years and so the need for solar panel cleaning has been realised.

When you first had solar panels installed you probably did not even consider the need to keep them clean. Most panels have a glass surface just like windows and so get dirty just like windows. In fact due to the position of the panels facing upwards they are more prone to bird dropping deposits and other debris settling on the surface.

Why do solar panels need cleaning?

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 costal 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 25-30% 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.

How to clean solar panels

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.

It is recommended that you hire a cleaning company that provides a solar panel cleaning service that know how to clean solar photovoltaic panels properly.

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.

How often should I clean my solar panels?

In the UK this is something that we do not have much experience or knowledge with. Luckily solar panel cleaning services in other countries have been established for many years and many recommend getting them cleaned twice a year. Some suggest you get them cleaned every couple of months.

For the best results the first clean should be at the start of spring as the days lengthen and the amount of sun reaching the panels increases. Later in the summer they should be cleaned again. For the UK climate this seems to be the best solution.

Won't the rain wash the dirt off the panels?

 During the summer there may be long periods where it does not rain and the summer is when photovoltaics produce the most electricity. When it does rain some of the loose dirt is removed but more is deposited in its place. Some types of soiling such as that from birds will remain for many weeks and even months if they are not cleaned.

Does cleaning a solar panel really improve its efficiency?

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."
