Pressure washers are great for cleaning the exterior of your home but should never be used on solar panels. Yes, the high reach and pressure can make cleaning large sections of solar panels much easier, but doing so runs the risk of damaging or cracking solar panels and causing micro-cracking, which is when the underlying solar cells break. The cells can continue to generate electric current along the cracks, causing localized heat that breaks down the cell surface and EVA. If water vapor is also present, discolored snail trails are formed along the microcracks, and these reduce energy production and compromise appearance.
It’s not recommended to use any high-pressure cleaning (pressure washer) or chemicals on solar panels, as these can damage the anti-reflective coating (ARC). The ARC on a solar cell helps to increase the amount of light absorbed into the cell. This coating is needed, as the reflection of bare silicone solar cells is over 30%.
Nowadays, not only do the solar cells carry anti-reflective coating, but such a coating can also be used on the glass surface (superstate) of solar panels.
ARCs on the solar panel’s glass will improve the light transmittance and increase the PV module’s overall efficiency. Another advantage of these coatings is that they can be anti-microbial and hyperbolic, reducing heavy buildup and mildew growth on the panels.
Not all coatings are the same. Some manufacturers use an inferior coating or don’t coat the outer glass surface of the panels. The good news is that a new coating can be applied to your solar panels to keep them producing power efficiently.
Clean Solar Panels Hawaii does not use any high-pressure cleaning or chemicals — per most manufacturers’ recommendations. The company only uses purified water and a particular solar panel cleaning brush. The business is also the exclusive distributor of DFI coating in Hawaii.
