At Keenwick, we clean the solar panels that power Maryland homes and commercial buildings, from residential rooftop systems to larger commercial arrays. Pollen, bird droppings, tree debris, and salt air leave a film that rain does not always clear, and we remove it with gentle, low-pressure methods, so your panels come back clean without scratched glass or stressed seals.
Solar panel cleaning removes the pollen, dust, bird droppings, leaves, and grime that settle on the glass and block sunlight from reaching the cells. When that layer builds up, your system can produce less power than it should.
Panels need a careful touch. Abrasive brushes, harsh chemicals, and high pressure can scratch the glass or wear down its coating, and a strong spray can push water past seals and into wiring. Many manufacturers also publish their own care guidelines, so the wrong method can put a warranty at risk.
At Keenwick, we look at your system first, then clean with soft brushes and a low-pressure rinse. It is the same gentle thinking behind our soft washing service, applied to glass that has to keep working for years. Our technicians are background-checked and trained, so you get consistent, careful results on every visit.
For commercial buildings, a solar panel cleaning service also has to fit around daily operations. We plan access and timing with you so the work causes as little disruption as possible for tenants, staff, and customers.
We start by walking the property to note where the panels sit, the roof type, how we will reach them safely, and what kind of buildup is on the glass. We also protect nearby plants and landscaping before we begin.
We clean each panel with soft brushes and a low-pressure rinse, never abrasive tools or high pressure. Then we check the array for spots, streaks, and missed edges so every panel looks even and clear. If we notice something that looks off, such as a cracked panel or loose wiring, we let you know so your solar installer can take a look.
Solar panel cleaning pairs well with other work at roof level. Many homeowners schedule it alongside other services so the whole house gets attention in one visit.
Solar panel cleaning works best as part of a full exterior refresh. Here are the related services we offer across Maryland.
Streak-free interior and exterior window cleaning, including sills and tracks. A natural add-on when we are already on-site cleaning your panels.
Low-pressure soft washing that removes algae, moss, and black streaks without damaging shingles. A cleaner roof means less debris working its way onto your panels.
Careful cleaning for skylights inside and out, clearing grime and buildup so more natural light reaches the rooms below.
Removal of leaves, debris, and buildup from your gutters so water drains away from your roof and foundation the way it should.
Gentle, low-pressure cleaning for roofs, siding, and other delicate surfaces that heavy pressure can harm.
Streak-free interior and exterior glass for storefronts, offices, and multi-story buildings, keeping your property looking professional year-round.
Exterior cleaning for building facades, sidewalks, parking lots, and entryways that removes stains, grime, and buildup safely.

Keenwick sent Eric over this morning to power wash our house and he did an incredible job! He showed up within the VERY reasonable 30 minute window, he was polite, left no mess, and did not take nearly as long as I thought it would. 5 stars easy.Posted on Google![]()

Eric was here on time and worked diligently to remove the iron deposits on my house. Considering the challenge, he did a great job and I am very happy with the results. I strongly recommend Keenwick for home/house cleaning requirements.
It depends on the number of panels, how they are mounted, how easy they are to reach, how much buildup is on the glass, and whether you bundle the visit with other exterior cleaning. A small ground-level array and a steep two-story rooftop system are very different jobs, so we do not use one flat price for every property. Reach out for a free quote based on your specific system.
