Solar Panel Cleaning in Delaware
Keep Your Delaware Solar Panels Performing the Way They Should
Dirty solar panels lose efficiency. Dust, pollen, algae, and bird droppings block sunlight absorption, and homeowners across Delaware see the impact on their electricity costs when panels go uncleaned through a full pollen season or a year of coastal salt film buildup. The residential solar market in Delaware continues to grow, and keeping panels clean is one of the simplest ways to protect what they generate. The longer the buildup sits, the more generation the panels lose and the more the home draws from the grid.
At Ortiz Pro Wash, we clean residential and commercial solar panels using a gentle pressure wash followed by a specialized cleaning solution and soft brush. Every job starts with a wiring and crack inspection before any water is applied, and we recommend annual cleaning to keep panels performing at their best.
Call us at (302) 228-6599 for a free written estimate. We will assess the installation, the panel count, and the contamination level so you know what the job involves before any work begins.
The Solar Panel Installations We Clean
Residential rooftop panels are our primary work, with commercial and ground-mounted installations available.
Residential Rooftop Solar Panels
Residential rooftop panels are the most common solar installation across Delaware and the panel type we clean most frequently. Ladders and harnesses are used when roof access is required; the crew works from the ground where possible. Since the panels sit on the roof, many homeowners schedule a roof soft wash at the same time to clear algae and growth from the shingles around them.
Commercial Solar Panels
Commercial panels are cleaned using the same gentle process. Scope, panel count, and scheduling are discussed at the estimate stage, and the crew adjusts for the installation size and access requirements.
Ground-Mounted Solar Panels
We can clean residential ground-mounted arrays as well but these setups vary, so give us a call and we’ll talk through your specific installation before quoting.

Why Delaware Homeowners and Businesses Choose Us for Solar Panel Cleaning
Solar panels are an investment, and the crew that cleans them should treat them that way. The same crew also handles house washing and other exterior work when you want the whole property maintained in one visit. Here is what sets our process apart.
Safety Inspection Before Any Water Touches the Panels
We inspect panels for exposed wiring before we start. Safety always comes first. If exposed or damaged wiring is found, the crew stops and notifies you immediately so the issue can be addressed by a qualified electrician before cleaning proceeds.
Specialized Solution and Soft Brush, No Abrasive Tools
A gentle pressure wash removes loose debris first. Then a specialized solar panel cleaning solution is applied with a long-handled soft brush. Only soft-contact tools are used throughout the entire cleaning process.
Ground Access Where Possible, Ladders and Harnesses When Needed
The crew works from the ground where safely possible. When roof access is required, ladders and harnesses are used with the same safety standards applied on roof cleaning jobs.

We provide a full Material Safety Data Sheet so you know exactly what we are using on your home. No guesswork, no surprises.

How Our Solar Panel Cleaning Process Works
The Free Written Estimate
Contact us by phone or email with your project. We assess the panel count, installation type (rooftop, commercial, or ground-mounted), level of contamination, and roof access requirements. Annual cleaning is discussed as the recommended maintenance cadence. You receive a written estimate with no obligation.
Pre-Job Safety Inspection
We inspect panels for exposed wiring before we start. Safety always comes first. If exposed wiring is found, the crew stops and notifies you immediately. Cleaning does not proceed until the wiring is repaired by a qualified electrician. Any cracks or panel damage are documented and communicated to you directly.
Gentle Pressure Wash
A gentle pressure wash is applied to remove loose debris, dust, algae, and bird droppings from panel surfaces. No aggressive pressure is used. The crew works from the ground where possible; ladders and harnesses are used when roof access is required.
Specialized Solution and Soft Brush
A specialized solar panel cleaning solution is applied across all panel surfaces using a long-handled soft brush. The solution is worked across the full surface to lift remaining contamination, including pollen film, salt residue, and organic buildup that the pressure wash alone did not fully remove.
Final Rinse and Completion Inspection
Panels are rinsed clean with all cleaning solutions fully removed. The crew inspects the panels at completion and communicates any damage findings to you. If anything was noted during the pre-job inspection or spotted during the cleaning, this is when it is brought up.
Invoice
Residential: payment collected on-site if you are present, or we send an invoice at net 15 or net 30. Commercial: invoice sent at net 30 or net 60 depending on the property management company. We accept cash, credit card, check, Zelle, Venmo, and PayPal.

What Delaware Homeowners Are Saying About Their Solar Panel Cleaning
Frequently Asked Questions
Will dirty solar panels really affect my electricity bill?
Yes. Dirty panels generate less electricity because dust, pollen, algae, and bird droppings block sunlight absorption. Reduced generation means the home draws more from the grid, which increases costs. Heavy spring pollen and coastal salt film are two of the most common efficiency-reducing contaminants on panels across Delaware. Annual cleaning is recommended to maintain peak performance.
Is it safe to put water near my solar panels?
We inspect panels for exposed wiring before we start. Safety always comes first. If exposed wiring is found, the crew stops and notifies you immediately. Beyond the wiring check, the crew also looks for cracks and loose connections before any water is applied. Water is applied at low, controlled pressure throughout.
How do you clean solar panels without scratching them?
A gentle pressure wash removes loose debris first. Then a specialized solar panel cleaning solution is applied with a long-handled soft brush. Only soft-contact tools are used on the panel surface. The process is designed specifically for panels, not adapted from a general pressure washing approach.
How often should I have my solar panels cleaned?
Once a year is the standard recommendation. Homes in high-pollen areas or near the coast may benefit from cleaning more frequently since pollen and salt film accumulate faster in those conditions.
Do you clean the panels on the roof or do I need to have them moved?
Panels stay in place. The crew works from the ground where safely possible and uses ladders and harnesses when roof access is required. No removal is necessary. Because we are already working at roof level, it is a convenient time to add a gutter cleaning and handle both jobs in one trip.
What happens if you find cracked or damaged panels during the inspection?
Any cracks, loose connections, or exposed wiring found during the pre-job inspection are documented and communicated to you immediately. If exposed wiring is present, the crew does not proceed until a qualified electrician has addressed the issue. Cracked panels without exposed wiring are flagged for your decision before the crew moves forward.
Do you clean ground-mounted solar panels?
Yes, residential ground-mounted arrays are within our scope. Setups vary, so call us to discuss yours and we’ll assess access and panel count before quoting.
How long does a solar panel cleaning take?
Most residential rooftop jobs take 1.5 to 2 hours. Larger installations, more contaminated panels, or installations requiring extensive roof access may take longer, and that is factored into the estimate.
What cleaning solution do you use on the panels, and is it safe for the equipment?
A specialized solar panel cleaning solution formulated for panel surfaces is used on every job. It is applied with a long-handled soft brush with no abrasive contact. A Material Safety Data Sheet is available on request if you want to verify the specific products used on your equipment.
