Solar Panel Cleaning Services
Boost output. Cut downtime. Protect your solar investment. Professional commercial cleaning, trained crews, modern equipment, and nationwide service.
Soiling is the single largest controllable cause of solar underperformance. According to the U.S. National Renewable Energy Laboratory (NREL), soiling causes roughly 3 to 5 percent of annual energy loss on average, and materially more in dry, dusty, and agricultural regions; peer-reviewed field studies have measured losses exceeding 1 percent per day during heavy dust events. Every Detail Solar provides commercial-grade cleaning designed to recover that lost output and document the result.
What is included
- Pre-clean soiling assessment with documented baseline output
- Pure water deionized rinse to prevent mineral spotting (we target 2 to 20 ppm contaminants, versus 300 to 1,800 ppm in typical hose water)
- No chemicals, low-water cleaning process suited for environmentally regulated sites
- Soft brush and microfiber agitation to lift hardened soiling
- Bird dropping, lichen, and hardened debris removal
- Frame and edge cleaning to prevent micro-shading
- Post-clean inspection report with before-and-after photos

Frequently asked questions
How often should commercial solar panels be cleaned? +
Every 6 to 12 months is typical, with quarterly cleaning recommended for sites near agriculture, industrial zones, or wildfire-prone areas. Sites in arid, dusty, or agricultural regions often need cleaning every 90 days.
Will cleaning damage my panels or void warranties? +
No. We use deionized water and soft brushes that meet manufacturer cleaning guidelines. We document our procedures so they align with your warranty terms. On request, we provide written procedure confirmation before the job.
Do you offer multi-site or recurring programs? +
Yes. We build maintenance programs for operators with 2 to 200-plus sites. Consolidated scheduling, unified reporting, and a single point of contact across your full portfolio. Portfolio clients receive priority scheduling and reduced per-site mobilization.
What scale of installation do you service? +
From single commercial rooftop arrays under 50 kW to multi-megawatt utility-scale solar farms covering hundreds of acres. We deploy different crew and equipment models depending on site size, mount type, and access conditions.
Do you provide before-and-after output data? +
Yes. We establish a pre-clean production baseline, complete the cleaning, and provide a post-clean verification report documenting recovered output. The data goes to ownership, O and M, or your lender in the format you specify.
How much does solar panel cleaning cost? +
Pricing varies by site size, mount type, and access difficulty. Most commercial rooftop and ground-mount projects run between $0.10 and $0.30 per watt per clean. We always provide a free production-loss estimate first so you can evaluate ROI before committing to cleaning costs.
What cleaning method do you use? +
Deionized water rinse with soft rotating brushes calibrated by panel type. Deionized water leaves no mineral deposits or streaks - just clean glass. For high-traffic utility sites we use semi-autonomous brushing equipment that cleans faster without compromising surface integrity.
How do I schedule commercial solar panel cleaning? +
Contact us through the form on this page or the contact-us page. Include your site address, array type, system size in kW, and mount configuration. We respond with a free production-loss estimate and cleaning quote within one business day.
Is cleaning cost-effective compared to lost output? +
In most environments, yes. NREL data shows soiling reduces output 3 to 5 percent annually on average, with losses exceeding 1 percent per day in heavy dust events. On a 500 kW site at $0.07 per kWh, a 4 percent soiling loss equals roughly $12,000 per year in foregone revenue. Most cleaning programs pay back in a single season.
Do you work with solar O and M operators and asset managers? +
Yes. We work directly with operations-and-maintenance firms, asset managers, and EPC contractors who manage solar portfolios on behalf of investors. We can operate under your reporting templates, coordinate with your CMMS, and provide data in the format your investors require.
