When you invest in a solar panel system, you’re also entering into a contract with warranty and performance terms—often with fine print requiring regular maintenance and cleaning. Most solar panel manufacturers and installers include clauses that mandate periodic cleaning as a condition for keeping the warranty valid. In fact, many lease or purchase agreements specify that the homeowner must use a certified professional to clean the panels and keep records of all services performed.
This requirement is especially relevant in the Pacific Northwest. The damp, shaded environments in Pierce and King County create ideal conditions for moss, algae, and debris to accumulate on solar panels. Without regular cleaning, this buildup can damage the protective coating of the panels and lead to system inefficiency or failure. If a panel stops working due to neglect, your claim may be denied by the manufacturer or installer.
To safeguard your investment, it’s essential to have your solar panels cleaned by a reputable, insured professional and to maintain detailed service records. These records not only prove that you’ve fulfilled warranty obligations but also demonstrate proactive care. This documentation can also be useful if you ever sell your home, as it provides transparency and reassurance to potential buyers. By staying informed and proactive, you can enjoy the full benefits of your solar energy system while maintaining your coverage and peace of mind.
