Solar Panel Cleaning Services
Dirty solar panels lose up to 25% of their energy output. Bird droppings, pollen, dust, tree sap, and environmental film gradually reduce the light reaching your photovoltaic cells. Camano Enterprises provides professional solar panel cleaning across Vancouver and the Lower Mainland using gentle, streak-free methods that protect your panels and maintain warranty compliance.
Why Clean Solar Panels Produce More Energy
Solar panels generate electricity from sunlight. Any film, debris, or buildup on the glass surface reduces the light reaching the photovoltaic cells, directly reducing energy output. Studies consistently show that dirty solar panels produce 15-25% less energy than clean ones. In the Pacific Northwest, where sunlight hours are already limited for parts of the year, maximizing every ray of light that reaches your panels is essential to getting the return on investment you expected.
Our Cleaning Method
We use deionized water and soft-bristle brushes to clean solar panels — no harsh chemicals, no high pressure, and no abrasive tools. This method is recommended by most major panel manufacturers and protects the anti-reflective coatings that maximize panel efficiency.
- Deionized (purified) water: Leaves no mineral deposits or water spots on the glass surface.
- Soft-bristle brush systems: Gentle enough for delicate coatings but effective at removing stuck-on debris.
- No chemicals: No detergents, solvents, or cleaning agents that could damage panel coatings or void warranties.
- No high pressure: Water-fed pole systems deliver controlled, gentle flow that cleans without risk of damage.
- Streak-free results: Deionized water dries clean, leaving crystal-clear glass for maximum light transmission.
Protecting Your Warranty
Most solar panel warranties require regular maintenance and prohibit the use of harsh chemicals or abrasive cleaning methods. Using improper cleaning techniques can void your manufacturer's warranty, leaving you unprotected against defects or performance degradation. Our cleaning methods comply with the maintenance requirements of all major panel manufacturers.
How Often Should Solar Panels Be Cleaned?
The recommended cleaning frequency depends on your location, surrounding environment, and panel tilt angle.
- Standard installations: Annual or semi-annual cleaning is typically sufficient.
- Panels near trees: More frequent cleaning (semi-annual or quarterly) due to sap, pollen, and bird droppings from roosting birds.
- Flat-mounted panels: Collect more debris than tilted panels and may need more frequent cleaning.
- Commercial and industrial installations: Larger arrays benefit from scheduled maintenance programs to maintain consistent output.
- After significant weather events: Heavy storms can deposit debris that warrants an unscheduled cleaning.

Common Questions
Will cleaning my solar panels really make a difference?
Yes. Depending on the level of soiling, cleaning can restore 15-25% of lost energy output. For commercial installations, this translates directly to measurable savings on your energy bill.
Can I clean solar panels myself?
While it is technically possible, we do not recommend it. Improper cleaning methods (garden hose, household cleaners, pressure washers) can damage panel coatings, leave water spots, or void your warranty. Professional cleaning uses the right tools and techniques to protect your investment.
Do you clean rooftop solar installations?
Yes. We clean solar panels on commercial rooftops up to 4 storeys. Our crews are fully trained and insured for rooftop work with all required safety equipment.
Will your cleaning void my panel warranty?
No. Our deionized water and soft-bristle method complies with the maintenance requirements of all major solar panel manufacturers. We do not use chemicals, high pressure, or abrasive tools.
