Costs to clean solar panels vary by complexity of the job. Generally speaking, it can range between $8-$14 per panel with a minimum charge based on the cost of a 10 panel system. Clean solar panels help to maximize energy production and provide more value over time.

There is no standard guideline for if or how often solar panels should be cleaned. Some areas are subject to more soiling than others which will determine if/when to clean a solar system.

Cleaning solar panels can improve the energy production of your solar installation. In many cases, your installer may have accounted for soiling of your solar panels in the initial evaluation which means normal dust accumulation has already been factored in. Many factors play into how much soiling may occur on your panels. Consult your local solar professional for more details.

While there is no way to protect you solar installation from a direct hit by lightning, a properly installed system will have ground rods installed to help diffuse the energy from lightning into the earth. Should your solar installation become damaged or impaired by lightning, this would be subject to a homeowner's insurance claim. It is important to make sure that your insurance company included your solar system in your homeowner's policy coverage.
