What is solar panel cleaning?

Solar panel cleaning is the most common maintenance performed on residential phototactic (PV) energy systems, especially those in dry or windy areas. When dirt, dust, debris, or animal droppings accumulate on the surface of your solar panels, blocked sunlight can significantly reduce their energy production.

Should I clean my solar panels if it rains a lot?

In many parts of the country, occasional rain is typically enough to naturally and safely keep your solar panels clean and free of debris that could lower their energy production. So, if you get a good amount of rain this year, you can likely skip a cleaning or two.

How often should you clean solar panels?

In general, it's recommended to clean your panels at least once or twice a year. If you live in a dusty or heavily polluted area, you may need to clean your panels more frequently. While uncleaned panels will still work, dust and soiling (like on a car windshield) will lead to lower production output. Does rain clean solar panels?

Why should you clean your solar panels?

In the absence of remediation, dirt accumulation over time may result in corrosion or damage. This deterioration can be averted through routine solar panel cleaning. This prolongs the lifespan of the panels by ensuring they remain in pristine condition. Your investment is protected by this proactive approach.
