Solar Panel Cleaning

All homeowners can attest that having a solar panel system for the home is a worthwhile investment. Therefore, it would be prudent to ensure that this investment lasts for a long time by caring for it. Solar panel cleaning means having a professional cleansing of the panels occasionally.

The slight tilt of solar panels during installation means that rainwater can wash off the dirt. However, dust particles and bird droppings may accumulate and interfere with the solar panels’ energy output.

To address this problem, cleaning the solar panels once every six months may be the solution. Is your home located in a dry area or close to a construction site or a highway where there is excess airborne debris? If so, this may call for more frequent cleaning of the solar panels.

The protective gear and tools required for the task include: 
a safety harness
a hard hat
sturdy shoes
a soft, non-abrasive cloth or sponge

How to Clean Solar Panels

The first thing to do is to shut down the solar system.

Remove any loose debris on the panels, then using water and a soft cloth, gently clean the panels. Be sure not to make any scratches on the solar panels.

Detergent is not required unless a homeowner feels it is necessary. Here, it should be a very mild detergent.

Hose off the panels when finished to remove any residue, then switch the system back on.


Remember that the best time to clean the panels is early morning, as the dew softens the grime, making it easy to remove.
