How often do solar panels need to be cleaned?

This will all come down to how dirty your solar panels are and if they have lost their efficiency over time. We recommend having your solar panels cleaned every 6 to 12 months at a minimum.

If you let your solar panels build up with dust, dirt, grime and debris, it can greatly effect how much sun they can absorb and could prevent you from producing enough electricity to essentially lower your power bills to 0.

Having clean and sparkling solar panels will allow them to absorb far more light throughout the day and help massively reduce your power bills and even in some cases help your get credit on your power bills so the power company has to pay you every quarter.

The important thing is to maintain the optimal output of your solar panel system. There can be a decrease of 2% to 10% of solar output annually due to the thin layer of dust and dirt that can build up over time.

This is a very low figure as dustier areas or places with higher pollution like in dense cities can reduce the absorption of sunlight of up to between 10% and even as high as 50% on a standard solar panel system on your roof as almost all pollution has some form of dust and debris that can effect the maximum productivity of your panels.

If your solar panels are looking a little dull and not shining like usual, the best way to have your solar panels cleaned is to call a professional solar panel cleaning service and have them come to your residential or commercial property and give them a through scrub down to remove all of the debris from them so they start working like they should.

We can come to any residential or commercial property and use a hi tech pressure washing system to blast away and dust, dirt and grime that may be layered on your panels and ensure that they will be as clean as they where when they were brand new.
