Frequently Asked Questions

While rain will rinse a layer of dust from your panels, rain also carries its own particulates, leaving a dirty film as well as mineral deposits that can hamper production. Professional cleaning removes these contaminants completely.

For optimal performance and longevity, it is recommended that you clean your system 2-3 times per year, depending on your panels' exposure to elements such as pollen, dust, or bird activity.

We use a combination of pure deionized water and a soft, water-fed nylon brush system that is designed specifically for solar panel cleaning. This cleaning regiment removes contaminants, leaving a residue-free shine that uses no chemicals or coatings that could void your warranty or harm your panels.

Yes! Many solar panel manufacturers require regular cleaning as part of their warranty conditions. Professional cleaning not only helps maintain your warranty but also provides documentation of proper maintenance should you ever need to make a warranty claim.

Most residential solar panel cleaning services take 1-2 hours to complete, depending on system size and accessibility. Commercial systems may take longer. We work efficiently to minimize any disruption to your day while ensuring thorough cleaning.

While DIY cleaning is possible, we don't recommend it. Improper cleaning methods can damage expensive panels, void warranties, and create safety hazards from working on your roof. Our professional service eliminates these risks while ensuring optimal cleaning results.

Yes, we offer comprehensive pest management solar panel systems. We can install critter guards and mesh barriers to prevent birds, squirrels, and other animals from nesting under your panels. For existing infestations, we safely remove nests, clean accumulated droppings, and disinfect the surrounding area.

No, you don't need to be home during our service. As long as we have clear access to your solar panels and an outdoor water source, we can complete the cleaning while you're away. Many of our customers prefer this convenience. We'll provide before and after photos of your system and confirmation when the job is complete. However, if you prefer to be present, we're happy to schedule around your availability.

Absolutely! If you can see soiling on your panels, you are losing a minimum of 5-15% of potential efficiency. If the panel is heavily soiled, like after snowmelt or extended dry periods, you could be losing much more. This quickly translates to dollars lost. Improvements in efficiency also vary by soil level and location. Dust, pollen, bird droppings, and environmental pollutants create a film that blocks sunlight from reaching the photovoltaic cells. Our professional cleaning removes these obstructions, allowing your panels to capture maximum sunlight and convert it to electricity. Many customers see the improvement on their monitoring systems immediately after cleaning.

Deionized water is purified water that has had mineral ions (like calcium, iron, and sodium) removed. We use this specialized water for solar panel cleaning because it leaves no mineral deposits or streaks when it dries. Unlike tap water, which contains minerals that can leave spots and residue on your panels, deionized water dries completely clear, ensuring maximum light transmission. This spot-free cleaning is essential for maintaining optimal solar panel performance.

A solar panel cleaning includes a panel inspection (to check for loose panels, damage, infestation, or debris), a detailed cleaning, and a report that contains before and after-cleaning photos and gutter conditions.
