Solar Panel Cleaning in Delaware
Keep Your Delaware Solar Panels Producing at Full Power
Rooftop solar takes a beating from the Mid-Atlantic weather. Humid summers feed algae and organic growth, spring blankets the air with heavy pollen, and homes near the coast pick up a film of salt air. All of it settles onto the glass along with ordinary dust and bird droppings, and it accumulates faster than most homeowners expect. The problem also goes well beyond a dull appearance.
That layer of grime blocks sunlight from reaching the cells underneath, so the panels produce less power and your electric bill quietly creeps up to cover the difference. At Ortiz Pro Wash, we clean residential rooftop solar panels with a gentle method that clears the buildup and brings your output back where it belongs, all without scratching the glass.
If your panels have not been cleaned in a while, they are almost certainly costing you money. Call us at (302) 228-6599 and we will take a look.
What Sets Our Solar Panel Cleaning Apart
Cleaning a solar array is not the same as washing a wall, and a few things about how we work make the difference on this job.
We Inspect Every Panel Before We Touch It
Before any water goes onto the array, our crew checks each panel for cracks, loose connections, and exposed or damaged wiring. We inspect panels for exposed wiring before we start, safety always comes first, and if we find a problem we stop and tell you rather than working around it. You get told exactly what we find, never handed a surprise after the fact.
A Panel-Safe Method, Not Just a Hose
Cleaning a solar array well takes a lighter touch than cleaning a driveway or a wall, and that is where a lot of the value on this job lives. We match real cleaning power to a surface that has to stay unscratched, working the glass until it is genuinely clean while treating it as the delicate, output-critical component it is. The result is panels that look and perform their best, with nothing sacrificed to get there.
Eco-Friendly Solutions, Adjusted to the Weather
The solutions we use are eco-friendly and biodegradable, and we adjust our mix to the conditions on the day of the job. The same care we bring to roof cleaning, where protecting your landscaping and managing roof runoff matters just as much, is the care we bring when we are working over your home, because that is simply the right way to clean.
How Our Solar Panel Cleaning Works
The Free On-Site Estimate
Reach out by phone or email, and we respond quickly and follow up by both. We schedule a visit to look at your array size, panel condition, and roof access, walk through the full scope with you, and answer your questions on the spot. You get a written proposal by email afterward, with no charge and no obligation.
Scheduling and the Heads-Up
Once you approve the quote, we get you on the schedule and send a reminder as the date approaches. About an hour before we arrive, we let you know we are on the way.
Pre-Start Panel Inspection
Before any cleaning begins, the crew inspects the panels for cracks, loose connections, and exposed or damaged wiring. If we find exposed wiring, we stop and let you know before going any further. We work from the ground where possible and use ladders and harnesses when roof access is required.
Gentle Wash to Clear Loose Buildup
A gentle pressure wash removes loose dust, pollen, algae, and bird droppings from the glass. It is low-impact and sized to protect the panel surface rather than blast it.
Specialized Solution and Soft-Brush Detail
We apply a specialized solar panel cleaning solution and work it in with a long-handled soft brush to lift the film that a rinse alone leaves behind, all without scratching the glass.
Rinse and Completion Inspection
We rinse the panels thoroughly, then inspect the array again at completion and note any findings to you.
Walkthrough and Invoice
If you are home, we walk the finished job with you. The invoice follows once you are satisfied with the result.
What Solar Panel Cleaning Costs in Delaware
Most residential solar panel cleans fall within a documented range, and the final figure comes down to your specific array, how dirty it is, and how easily the crew can reach it.
- Solar Panel Cleaning runs $200–$500–$600, priced by the number of panels, the level of contamination, and the complexity of access. Smaller ground-accessible arrays land near the low end, while larger arrays, heavier buildup, or roof access that calls for ladders and harnesses move the price up.
- If you combine solar panel cleaning with another service on the same visit, such as a house washing or gutter cleaning, a bundled rate may apply since the crew is already on-site. Ask about it when you get your estimate.
Our Promise on Every Solar Panel Job
We stand behind our work. If you reach out and you are not happy with the service, we come back and make it right. In the rare case that a return visit does not settle it, we work with you on a partial refund. Either way, the job is not finished in our eyes until you are satisfied with it.
Frequently Asked Questions
Does cleaning my solar panels actually improve their performance?
Yes. Dirty panels lose efficiency, and clearing them restores output. Dust, pollen, algae, and bird droppings block sunlight from reaching the cells, which lowers how much electricity the panels produce and pushes your power costs up. Once the glass is clean again, the panels absorb sunlight the way they were designed to.
What do you do if a panel is cracked or has exposed wiring?
If the crew finds exposed or damaged wiring during the pre-start inspection, we stop and notify you, and we will not proceed until it is addressed. Applying water near exposed electrical is a safety hazard, so this is a firm rule rather than a judgment call. We check for cracks and loose connections at the same time and tell you what we find before any cleaning begins.
How often should I have my solar panels cleaned?
We recommend cleaning once a year to keep panels performing at their best. Delaware’s heavy spring pollen, coastal salt air, and humidity-driven organic growth load panels faster than in drier climates, so an annual clean keeps your output from quietly slipping. Homes near the coast or under heavy tree cover may benefit from checking the panels more often.
Will pressure washing damage my solar panels?
No. Our method is built to protect the glass. We use a gentle pressure wash to lift loose debris, then a specialized solar panel cleaning solution applied with a long-handled soft brush, followed by a clean rinse, which gets the panels truly clean without scratching the surface. Solar glass scratches easily and a scratched panel loses output, so we never blast panels with high pressure.
