Safe, Streak-Free Solar Panel Cleaning for Your Home
Maximize Your Solar Performance
Dirty solar panels don’t just look bad—they can cost you energy and money. Even a thin layer of dust or debris can reduce solar efficiency by 15–30%. That’s why B & B Window and Gutter Cleaning provides professional residential solar panel cleaning for homeowners throughout the Bay Area and Sacramento, using safe, effective methods that protect your panels and restore peak performance.
Our experienced team uses pure water technology and soft, non-abrasive brushes to remove grime without scratching your panels or damaging wiring. We never use high pressure, and we avoid harsh chemicals that could reduce your panels’ lifespan. Whether your system is roof-mounted or ground-mounted, we ensure every panel is safely accessed, cleaned, and inspected.
Regular cleaning is especially important in areas prone to dust, pollen, coastal air, or nearby trees. We recommend solar panel cleaning at least once or twice a year to maintain output and protect your long-term energy savings.
