Dirty panels lose power. Pollen, salt air, bird droppings, and dust can quietly cut your solar output by 5 to 25 percent. We restore that lost production with low pressure, panel safe cleaning methods that protect your warranty and your investment. Veteran owned, serving all of Onslow County and the Crystal Coast.
Solar panels are precision optical surfaces. Every square inch of glass between the sun and the photovoltaic cells underneath has to stay clear for your system to produce at its rated output. In Jacksonville and Eastern North Carolina, that glass picks up a long list of contaminants that block sunlight and silently cut performance. Pine pollen coats every exterior surface from late February through May. Salt air carries inland from the Atlantic and bonds with dust to form a sticky film that rainwater alone will not remove. Bird droppings deposit concentrated, opaque spots that block specific cells. Humidity supports algae and mildew growth around panel frames and along seal lines. Construction dust, vehicle exhaust, and tree sap add another layer in residential neighborhoods.
Industry research and real world testing have shown soiled residential solar arrays can lose anywhere from 5 to 25 percent of their rated output, with heavier buildup pushing losses higher. That is real money. For a typical Jacksonville home with a 6 to 10 kilowatt system, a 15 percent loss can equal hundreds of dollars in lost electricity production each year, year after year, until the panels are cleaned. The loss does not show up as a single bad month. It shows up as a gradual decline that most homeowners assume is normal aging.
The performance hit happens fastest in the spring pollen season and during dry stretches between rains. It builds quietly in the background. If you have not had your panels professionally cleaned since installation, there is a strong chance they are producing well below their potential right now. The good news is that the loss is fully recoverable. A single professional cleaning typically restores most or all of the lost output, and a consistent annual or biannual cleaning schedule keeps your system running close to peak performance for its full service life.
Solar panels are also a major capital investment. Residential solar systems typically represent a substantial financial commitment, often financed over 10 to 20 years. Protecting that investment is straightforward, but it requires the right tools, the right water, and the right technique. We bring all three.

Jacksonville and the surrounding Onslow County area sit at the intersection of three conditions that accelerate panel soiling. Heavy pine pollen from late winter through spring coats every exterior surface in fine yellow dust that bonds to glass and resists rinsing. Coastal salt air reaches inland on most days, carrying sea salt droplets that settle on the array and combine with airborne dust to form a sticky residue. High summer humidity supports algae and mildew growth along panel frames, junction boxes, and seal lines.
Add to that the everyday contributors. Tree sap from oak, pine, and sweetgum trees common in coastal NC neighborhoods. Bird droppings, which are concentrated enough to permanently shadow individual cells if not removed promptly. Construction dust from active building sites across Jacksonville. Vehicle exhaust and road grime carried by wind, especially for homes near major roads or the base. Each contributor on its own is manageable. Layered over months or years, they compound into a thick, uneven film that significantly degrades performance.
Many homeowners assume rain will keep panels clean. It will not. Rain pushes contaminants around the panel surface and then evaporates, leaving mineral spots and concentrated soiling along the lower edge of each panel where water pools before running off. After a rainstorm, panels can actually produce less than they did beforehand because of the redistributed dirt and water spotting. Professional cleaning with the right water and the right tools is the only reliable way to restore peak performance.
Step 1: System Assessment. Before we touch your array, we inspect the panels, mounting hardware, and roof condition. We note any visible damage, hot spots, or unusual soiling patterns that may indicate a deeper issue worth flagging to your installer. We confirm panel type and orientation so we can match our process to your system. We also check the time of day and surface temperature, because applying cool water to hot glass risks thermal shock and microcracking. Cleaning happens early in the morning or on overcast days when panels are cool.
Step 2: Low Pressure Rinse. We start with a low pressure water rinse to lift loose pollen, dust, and surface debris. Pressure stays well below the threshold that can disturb seals, junction boxes, or panel framing. We never use a standard pressure washer on panels. The combination of high pressure and the wrong angle can drive water past seals, damage anti reflective coatings, or crack cells. Low pressure does the job safely and protects your warranty.
Step 3: Soft Brush Cleaning With Panel Safe Solution. For bonded soiling like pollen film, salt residue, bird droppings, or tree sap, we apply a biodegradable, panel safe cleaning solution and agitate gently with a soft bristle brush designed for solar arrays. No abrasive pads, no scouring, no harsh chemicals. The brush bristles are softer than the panel glass and will not scratch the anti reflective coating. We work in sections, taking the time to address each panel evenly so the result is consistent across the array.
Step 4: Purified Water Final Rinse. We finish with a purified water rinse. Tap water from a garden hose contains dissolved minerals, calcium, and other solids that evaporate into spots on the panel surface. Those spots themselves block sunlight and partially negate the cleaning. A purified water final rinse leaves the glass spot free and streak free, so your panels dry to a clean, optically clear surface. This is one of the most important differences between a DIY rinse and a professional cleaning.
Step 5: Frame, Edge, and Surrounding Surface Cleaning. We clean panel frames, junction box exteriors, and the seal lines where algae and mildew often grow. We also clean the surrounding roof area immediately around the array, because debris there can blow back onto the panels within days. Many homeowners pair solar panel cleaning with a full roof cleaning for a complete result.
Step 6: Final Walkthrough. We document the condition of your array, share before and after observations, and confirm the work meets our standard before we leave. We do not walk on your panels at any stage of the job. All work is done from the edges using extended reach tools and proper safety equipment. Walking on panels is dangerous and can crack cells or damage mounting hardware, and it is something we will never do.
Solar panel warranties cover decades of performance, but they come with conditions. Most manufacturer warranties require that panels be cleaned using non abrasive methods and that no high pressure equipment be used on the array. Using a standard pressure washer, abrasive scrubbing pads, or harsh chemical cleaners can void the warranty, and damage that results from improper cleaning is not covered. Our entire process is designed around manufacturer guidelines: low pressure water, soft bristle brushes, panel safe biodegradable solutions, and purified water rinses.
We also protect your monitoring data. If your system has production monitoring, professional cleaning records help establish a baseline if you ever need to file a warranty claim for underperformance. A pattern of consistent, documented cleaning rules out soiling as the cause of low output, which strengthens your case if a panel or inverter fails to meet its rated specifications.
If you are not sure what your warranty requires, we are happy to look at the documentation with you. Our cleaning process follows the documented care guidelines from major panel manufacturers, and we will confirm our method matches your specific manufacturer's requirements before we begin work. Request a quote and bring your warranty questions to the assessment.
We do not service the electrical or mounting components of your system. If we notice anything during our visit that looks like a job for your installer or an electrician, we will tell you and document it so you can follow up with the appropriate professional.
For most Jacksonville homes, professional solar panel cleaning once per year is the right baseline. That single annual visit clears the pollen load from spring, the salt and dust buildup from summer, and any algae or mildew that took hold around the frames during the humid months. For homes located close to the coast, near heavy tree cover, or under bird flight paths, twice a year is often the better choice.
The best time of year for a primary annual cleaning in Eastern NC is late spring, after pine pollen season tapers off in May. Cleaning at this point removes the heaviest soiling load of the year and sets up your system for peak summer production when sun hours are longest and electricity rates often peak. A second cleaning, where appropriate, fits naturally in early fall after the worst of summer storms and before leaves start dropping in October.
Commercial systems that drive measurable revenue from their production typically benefit from a quarterly or biannual schedule, depending on the surrounding environment and the size of the array. We offer recurring maintenance scheduling that takes the planning off your plate. Ask about a recurring solar cleaning plan when you call.

Based in Jacksonville, NC. Serving Onslow County and the surrounding communities.
Most Jacksonville homeowners see a meaningful jump in production after a professional cleaning, typically in the 5 to 25 percent range depending on how soiled the array was. Heavier buildup from pollen, salt, and bird droppings produces a larger recovery. Lightly soiled systems see less dramatic but still real gains. If you have production monitoring, you can compare daily output before and after the cleaning to see the result directly. We aim to leave your array producing at or very close to its rated output for current sun and weather conditions.
Rain does not clean panels effectively. Rainwater pushes contaminants around the surface and then evaporates, often leaving mineral spots and concentrated soiling along the lower edge of each panel. After a rainstorm, panels can actually produce less than they did beforehand because of redistributed dirt and water spotting. Professional cleaning with low pressure and purified water is the only reliable way to fully restore performance.
A garden hose rinse can knock off loose dust, but tap water in most of Onslow County contains dissolved minerals that leave spots when the water evaporates. Those spots block sunlight and partially defeat the cleaning. A garden hose also does nothing for bonded contaminants like pollen film, salt residue, tree sap, or bird droppings. Professional cleaning combines low pressure water, panel safe solutions, soft brushes, and a purified water final rinse to do the job correctly.
No, professional cleaning that follows manufacturer guidelines actually helps protect your warranty. What can void a warranty is using a standard pressure washer, abrasive pads, harsh chemicals, or walking on the panels. Our process uses low pressure water, soft bristle brushes, biodegradable panel safe solutions, and purified water. We follow manufacturer care guidelines and provide documentation for your records.
No. Walking on solar panels can crack cells, damage seals, and void warranties. We clean from the edges of the array using extended reach tools and proper fall protection equipment, following manufacturer best practices. We never put weight on the panels themselves.
Early morning or on overcast days when the panels are cool. Applying cool water to hot panel glass can cause thermal shock and microcracking. We schedule cleaning sessions for the cooler parts of the day and avoid working on panels that have been in direct midday summer sun.
Once per year is the baseline for most Jacksonville and Onslow County homes. Twice per year is the right call if you are close to the coast, under heavy tree cover, or in a high pollen area. Commercial systems with measurable revenue from their production often benefit from quarterly or biannual cleanings. We offer recurring maintenance scheduling so you do not have to remember to call.
Yes. Ground mounted arrays are easier to access than roof systems and the cleaning process is the same. We use low pressure water, panel safe solution, soft brush agitation, and a purified water final rinse. We also clean the area around the array footings where vegetation and debris collect.
Yes. We service commercial rooftop and ground mounted arrays across Jacksonville and Eastern NC. We coordinate scheduling around your business hours, provide documentation suitable for facility records, and offer recurring maintenance contracts for ongoing performance management.
Bird droppings and tree sap are two of the most stubborn contaminants and two of the most damaging if left in place. Bird droppings are concentrated enough to permanently shadow specific cells and create hot spots over time. Sap bonds tightly to glass and resists rinsing. Our panel safe biodegradable solution plus soft brush agitation removes both without scratching the anti reflective coating or damaging seals.
Yes, and it is one of the most efficient ways to keep your roof system clean. Many Jacksonville homeowners pair solar panel cleaning with a full roof cleaning, gutter whitening, or house washing visit. Combining services on a single appointment reduces total cost and keeps the area around your array clean so debris does not blow back onto the panels within days. Ask about combined service pricing when you call.
