Solar panels work by allowing light into the solar cells. The more light that hits a panel, the more power it will generate. Due to the upwards angle of solar panels, they are more prone to bird droppings and a build-up of general dust and dirt that does not wash off with just rain. This reduces the amount of light hitting the panel and reduces its output. As the projected energy figures claimed by solar panel manufacturers and installers are based on the optimum performance of clean solar panels, this build-up of dirt can adversely affect the panel’s ability to meet those projections. So it is important to clean solar panels in order to protect and maintain your investment. Regular solar panel cleaning will also help you to make the most of the government feed-in tariff.
While solar panel cleaning in the UK is relatively new, in other parts of the world solar panel cleaning has been around for a long time. Early adopters of the technology soon realised that if their solar panels were not cleaned regularly, they would not run at their optimum performance. There has been study in the U.S. suggesting solar panel cleaning is not necessary in some of their climate, but it is proved that solar panel cleaning is necessary in the UK.
Why Clean Solar Panels - Your Warranty
Some solar panel manufacturers and installation companies have made solar panel cleaning a condition of their warranty. Should you have problems with your solar panels, if you do not have proof of regular solar panel cleaning by professionals, your solar panels may not be covered by the warranty. We have made a comparison of solar panel warranties and the message is the same, get your solar panels cleaned.
Why Clean Solar Panels - Can It Improve Efficiency?
We have for years now, been monitoring the increases in efficiency that solar panel cleaning can bring. We frequently see sizeable increases of solar efficiency on agricultural sites, of up to 30%. This has been proved by clients who have sent readings to prove solar panel cleaning has increased the output and efficiency of their array. O&M departments of companies that we have cleaned solar panels for have also reported similar increases in efficiency from solar panel cleaning.
On industrial and commercial sites, we have seen increases of up to 60% and on residential arrays of up to 21%.
Our own findings are confirmed by the World Academy of Science, Engineering & Technology, who say "a drop in the efficiency of a solar PV panel is not desired. One of the contributing factors in the drop of efficiency in solar PV panels is the accumulated dust on the solar panel. In practice, dust must be removed from the surface of solar PV panels in order to ensure highest performance." Solar Energy Power Association notes that dirty solar panels can lose 20% of their energy output. The National Renewable Energy Laboratory puts that figure even higher, at 25%. Recent university research has shown that a dirty solar panel can lose 50% of it's efficiency compared to a clean solar panel.
Why Have Solar Panel Cleaning From Clean Solar Solutions Ltd?
We are one of the most experienced solar panel cleaning companies in the whole of the UK, our whole business is solar panel cleaning. We have equipped ourselves with professional solar panel cleaning equipment, know how to clean solar panels safely and effectively and have positioned ourselves to offer a high quality professional solar panel cleaning service.
