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 sizable 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%.
