Solar Panel Cleaning Services

Maximize Your Energy Output & Protect Your Investment

Are Your Solar Panels Working at Peak Efficiency?

Your solar power system is a significant investment designed to save you money. However, even in dry climates, dust, pollen, bird droppings, pollution, and general environmental grime accumulate on your panels, creating a "dirt film."

This soiling effect prevents sunlight from reaching the photovoltaic (PV) cells, leading to a dramatic drop in energy yield. Studies show this dirt buildup can cause a 15–25% reduction in production.

Prestige Window Cleaning LLC offers professional solar array maintenance to ensure your system is generating the maximum amount of electricity possible, protecting your investment for years to come.

Why Specialized Cleaning is Non-Negotiable

Why Specialized Cleaning is Non-Negotiable

You cannot clean solar panels like ordinary windows. Using tap water or aggressive pressure washing is one of the quickest ways to damage the panels, create hard water spots, or even void your system warranty.

We employ the same technology trusted by leading solar installers:

  1. Deionized Water: We use a proprietary filtration system to purify water to the highest standards. This mineral-free, deionized water is gently sprayed onto the panels and allowed to run off, leaving absolutely no residue.
  2. Scratch-Free Method: We use only specialized, soft-bristled brushes designed for PV panel washing. We avoid abrasive cleaners and aggressive chemicals that can harm the anti-reflective coating on the glass.
  3. Roof Safety: Our technicians are trained in safe roof access and maneuvering around sensitive panel mounts and wiring, prioritizing the safety of both our crew and your roof structure.

  2. Warranty Protection: Proper, gentle cleaning techniques prevent damage and ensure the manufacturer's warranty remains valid.
  3. System Longevity: Eliminating corrosive bird droppings and mineral buildup protects the glass and frame seals from early deterioration.
  4. Clear Performance Tracking: Ensure accurate data when monitoring your system performance and catching potential hardware issues early.
Optimizing Solar Panel Output Through Maintenance

Frequently Asked Questions (FAQ)

  • No. Rainwater can rinse off large debris, but it lacks the necessary pressure and purity to remove sticky pollutants like pollen, dust film, and bird droppings. These residues solidify when they dry and significantly impact your module efficiency.
  • We generally recommend professional photovoltaic cleaning two to three times per year. This is particularly important after heavy pollen seasons (Spring) and any prolonged dry, dusty periods. The ideal frequency often depends on your local environment (e.g., proximity to highways or farms).
  • Tap water contains minerals (calcium, magnesium) that, when dried by the sun, leave behind hard water spots and mineral deposits. Over time, these minerals can etch into the panel glass and permanently damage your solar cells, compromising your system performance. Our deionized water process eliminates this risk.
  • We use absolutely zero chemicals or soaps to ensure your warranty remains valid. We rely solely on low-pressure, purified water and specialized soft brushes, which is the safest and most effective method recommended by leading panel manufacturers for scratch-free cleaning.
