Yes, homeowners can clean solar panels themselves, but it’s essential to use the right techniques and materials to avoid damage. A soft brush or squeegee with a long handle, combined with distilled or deionized water, is the safest way to remove dirt. Avoid using abrasive sponges, harsh chemicals, or pressure washers, as these can scratch the panels or weaken their protective coating. Cleaning early in the morning or late in the evening is recommended to prevent rapid water evaporation, which can leave streaks.

Although DIY cleaning can save money, it may not be as effective as professional services, especially for heavily soiled panels or difficult-to-reach installations. Additionally, climbing onto a roof poses safety risks. If you’re unsure about the best cleaning methods or want a hassle-free experience, hiring a professional service based on solar panel cleaning prices can ensure optimal efficiency without the risk of damage.
