Fast and Reliable Solar Panel Cleaning Services in Delaware

Protect Your Solar Investment
With Expert Panel Cleaning
in Delaware

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. 

Call today to schedule your eco-friendly solar panel washing service!

Schedule and Job Prep

Once you book a service via phone or online, we’ll schedule an appointment to confirm your panel count, roof pitch, and access needs. You’ll receive reminder texts or calls one to two days prior.

On-Site Inspection

Our technicians inspect your panels for: 

  • Cracked panels
  • Exposed wiring
  • Shifting/misaligned mounts

We may defer the job if we notice any safety risks. 

Cleaning With Deionized Water

We spray deionized water on your panel surface using a carbon fiber water-fed pole while standing on a ladder with a stabilizer. Heavy soil buildup may require multiple passes, and then we rinse the entire surface until the runoff is clear.

Please note we don’t use brushes on glass (only lightly on frames if needed).

Final Spot Check and Touch-Ups

Our team re-rinses any remaining residue and ensures a clean workspace, and that ladder points didn’t disturb your roof or garden.

Customer Update and Ongoing Plan Offer

We review the work, recommend our semi-annual plan, and collect payment onsite. We can email before-and-after photos upon request.

East Coast Window Cleaning is an exceptionally managed business with friendly technicians who treat your home with care and respect. We recently had our windows cleaned, inside and out. What an amazing job that was performed. The windows were crystal clear, streak free, and the sills were cleaned of all dirt and contaminents. We have tint on our windows, which we made the technician aware of, and we were assured they would be cleaned gently. Communication was paramount, including an arrival time frame, followed up by a call 30 minutes prior to arrival. You absolutely cannot go wrong hiring East Coast Window Cleaning.
Response from the owner:Anthony, thank you so much! We're really glad the windows came out streak-free and that our team took good care of your tinted glass. Knowing the communication stood out means a lot to us. We'd love to work with you again!

Frequently
Asked Questions

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.

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.

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.

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.

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.

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.

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.
