What should I avoid when solar panel cleaning?

Pressurized power washers should NOT be used for solar panel cleaning as they can damage the seals around the panels. Avoid using hard-bristled brushes or other items that can scratch the surface. Do not use harsh chemicals as they can harm the seals and or the panel glass. Avoid cleaning solar panels during the hottest hours of the day in order to avoid stress on the solar panels.

Can rain clean solar panels?

Rainfall cannot clean solar panels. Solar panels accumulate dust and grime that, when mixed with moisture, creates a sludge that adheres to panels which can only be cleaned with gentle scrubbing and the proper solar panel cleaning solution.

Can wildfire ash damage solar panels?

Wildfires generate ash that hurts solar panels mainly by blocking the sunlight and leaving a dirty, abrasive film that lowers how much light reaches the cells. When the ash mixes with moisture like dew, marine layer, or fog, it can leave a residue that is hard to remove. The sealants around the edges of the solar panels can be at risk due to the acidity of the ash mixture if left on for a long time and not cleaned

What are the best times of the year to clean solar panels in Ventura County, CA

The two best ideal times for solar panel cleaning are from March to June and Sept through November. The March to June window helps to maximize solar panel production before the long days of summer, when you should be generating the most amount of production credits with Edison. The September through November window removes all of the dust and grime that is accumulated during the dry summer months before the rainy season, where the dust and rain combine to create a grime that can really impact solar panel production.

Will cleaning my solar panels actually lower my SCE electric bill?

Southern California Edison customers will see a lower electric bill from increased solar production. For current SCE customers, the time-of-use pricing structure means that you need to be offsetting your electric usage during the times that matter the most. The late afternoon through evening time frame of 4 PM to 9 PM is the most expensive time to pay for electricity.
