Solar Panel Cleaning Service FAQs
Why use Sunnova Repair Services®?
More than a solar panel cleaning company, Sunnova is a leading name in solar energy solutions, serving 438K+ homeowners across America since 2012. Our technicians are experts in their field, undergo hundreds of hours of specialized training and are certified to work on most major solar brands.
How much does solar panel cleaning cost?
Our solar panel cleaning service starts at $300. However, your price may vary based on the size of your system, location, condition, improvements, updates, lot sizes and building type — among other factors.
My solar system isn’t from Sunnova — can I still use you?
Yes. Whether you originally purchased your solar system through Sunnova or another provider, our solar panel cleaning services are available to you.
Why can’t I just clean my solar panels myself?
While cleaning your solar panels yourself might seem simple, it’s not always the best idea. They’re often hard to access safely, and improper cleaning techniques or tools can damage the surface, interfering with efficiency. Hiring professionals ensures your panels are cleaned safely, thoroughly and without damage, preserving their performance and your investment.
Won’t rainwater just clean my solar panels for free?
Rain won’t always clean your solar panels. It can still leave behind contaminants that block sunlight and reduce energy output. Think of your car windshield after months without cleaning — rain may rinse it, but grime still builds up, clouding visibility. Solar panels face the same issue, so professional cleaning is key to maximizing sunlight (and energy).
How often should I clean solar panels?
We recommend getting your solar panels professionally cleaned 1-2 times a year, depending on the climate in your area.
