Constant exposure to coastal Delaware’s high humidity, salt buildup, and pollen will cause your solar panels to accumulate dirt, debris, and grime, which reduces performance. The veteran-owned East Coast Window Cleaning offers expert solar panel cleaning services in Delaware to help you prevent these problems.
Our chemical-free, damage-free method is ideal for residential rooftop systems, including fragile or high-end solar panel arrays. We use pure deionized water delivered through carbon fiber water-fed poles, so we don’t walk on your roof to prevent damage.
You don’t even need to be home during the service as long as we can safely access your panels. With our semi-annual maintenance plan, you can effectively preserve your solar energy output and protect long-term system warranties.

What Our Customers Say About
East Coast Window Cleaning
Frequently
Asked Questions
Do I need to turn off my solar system before cleaning?
In most cases, you do not need to turn off your solar system for cleaning. However, if your system has specific manufacturer recommendations or a disconnect switch that’s easily accessible, we may advise turning it off as a precaution. We’ll confirm any system-specific needs when you book.
Will cleaning improve my energy production right away?
Yes—professional solar panel cleaning can improve energy output immediately. Dirty panels block sunlight and reduce efficiency, so removing that buildup helps your system perform at its best. Results are often most noticeable on heavily soiled systems or after long cleaning gaps.
Do you provide documentation or photos to show that the cleaning was done properly?
Yes, we can provide before-and-after photos upon request. If we find any damage or issues during inspection, we also document those and share them with you. This gives you peace of mind and a visual record of the work completed.
Is solar panel cleaning safe during certain weather conditions, like cold or overcast days?
We can safely clean solar panels in most weather, including cloudy or cool days. However, we avoid working during storms, freezing conditions, or high winds for safety reasons. If weather could affect your appointment, we’ll contact you to reschedule.
Do you clean Tesla solar panels or other specialty brands?
Yes, we clean Tesla solar panels and most other residential solar panel brands. Our pure-water cleaning method is safe for all common glass and frameless panel types. If your system has unique installation features, we’ll review it before starting.
Can you remove hard water stains or calcium buildup from my solar panels?
We can remove most mineral deposits using multiple passes with pure deionized water. However, if the buildup is severe or long-standing, full removal may not be guaranteed. We’ll assess the condition during our pre-clean inspection and let you know what to expect.
What kind of water do you use—and why is it better than hose water?
We use pure deionized water, which dries completely spot-free and leaves no mineral residue. Unlike regular hose water, it won’t create new water spots or leave behind hard water stains. It’s the safest and most effective method for solar panel cleaning.
