Questions

Yes. Dirty solar panels can lose up to 30% of their energy output. Professional cleaning typically restores 5-25% efficiency depending on the level of buildup. With Idaho's high solar irradiance (200+ sunny days per year), that translates to real savings on your energy bill.

No. Rain in Idaho doesn't provide enough force to remove caked-on dirt, bird droppings, pollen, or wildfire ash. In fact, light rain can make panels dirtier by mixing dust into muddy streaks. Idaho's semi-arid climate means long dry periods where buildup goes unchecked. Professional cleaning is the only way to ensure panels are performing at peak efficiency.

Yes. Idaho Solar Cleaning is fully licensed and insured. We carry comprehensive general liability insurance to protect your property. You can request a copy of our insurance certificate at any time.

We serve the entire Treasure Valley including Boise, Meridian, Nampa, Eagle, Star, Kuna, Caldwell, and Garden City. Contact us if you're outside these areas — we may still be able to help.

In Idaho's Treasure Valley, we recommend cleaning solar panels 2-4 times per year. Spring pollen, summer wildfire smoke, and agricultural dust create year-round buildup. Homes near farmland or with bird activity may need more frequent cleanings.

While you can attempt DIY cleaning, there are important risks. Idaho's hard water leaves mineral deposits that actually reduce panel efficiency. Climbing on roofs is dangerous without proper training and equipment. Using the wrong pressure or chemicals can damage the anti-reflective coating and void your warranty. Our purified water system and professional techniques are specifically designed to avoid these problems.

Bird proofing involves installing a stainless steel mesh barrier around the perimeter of your solar array to prevent birds from nesting underneath. If you see pigeons, starlings, or other birds landing on or under your panels, you likely need proofing. Bird droppings are highly corrosive and nesting debris can cause electrical faults and fire hazards.

Infrared thermal imaging reveals hot spots, micro-cracks, and failing cells that are invisible to the naked eye. These defects silently reduce your energy production and can worsen over time. We include a free thermal scan with every cleaning so you always know the health of your system.

Our anti-static glass coating is a specialized treatment applied after cleaning that repels dust and debris, keeping your panels cleaner for longer. The coating lasts 4-6 months and can reduce dust re-accumulation by up to 50%, increasing energy production by up to 5% between cleanings.

Residential solar panel cleaning starts at $179 depending on the number of panels, roof pitch, and accessibility. We provide free estimates with no obligation. Our maintenance programs start at just $30/month and include scheduled cleanings throughout the year.

We accept cash, checks, all major credit cards, Zelle, and Venmo. Our maintenance programs can be set up with automatic monthly billing. Bird proofing installations offer interest-free payment plans over 2-6 months.

A typical residential cleaning takes 30-60 minutes depending on the number of panels and level of buildup. Commercial cleanings vary by array size. We schedule cleanings to minimize disruption and can often complete the job while you're at work.
