FAQS

Here are answers to some common questions. 

  • How often should I clean my solar panels?

    We recommend cleaning your solar panels at least twice a year to maintain maximum efficiency. Dust, pollen, and debris can block sunlight and reduce your energy output by up to 25%. Homeowners near trees or construction areas may benefit from quarterly cleanings.

  • Can I clean my solar panels myself?

    Yes, but it’s not recommended. DIY cleaning can lead to scratches, broken glass, or electrical damage. Our team uses deionized water and soft-wash equipment that safely removes dirt without harming your panels or voiding your warranty.

  • Does professional cleaning really improve performance?

    Absolutely. After a proper cleaning, most customers notice a visible improvement in energy production. Our eco-friendly cleaning process restores clarity and efficiency, helping your panels capture the most sunlight possible.

  • What cleaning products do you use?

    We only use biodegradable, eco-safe cleaning solutions and purified water. This ensures no streaks, no residue, and no harm to your panels or landscaping.

  • How long does the cleaning take?

    A standard residential system takes about 60 to 90 minutes, depending on accessibility and system size. We’ll inspect your panels during the process and let you know if we spot any issues.

  • Do you offer maintenance plans?

    Yes! Many homeowners choose our annual or biannual maintenance plan, which includes discounted cleanings, visual inspections, and priority scheduling before peak solar months.

  • Is solar panel cleaning safe during the summer or winter?

    Yes. We clean panels year-round using the correct methods for every season. In winter, we avoid rapid temperature changes, and in summer, we clean early in the day to prevent overheating.

  • Are you licensed and insured?

    Yes, we are fully licensed, insured, and locally trusted throughout Tacoma and surrounding areas. Your roof and panels are protected from start to finish.
