Should you clean your own solar panels or hire professionals? It's a question every solar owner asks. The honest answer depends on your situation, comfort level, and what your time is worth. This guide breaks down the real costs, safety risks, results, and time investment for both DIY and professional solar panel cleaning in Kings County — no sales pitch, just facts to help you decide.

DIY Solar Panel Cleaning: Pros, Cons & Hidden Costs

DIY cleaning seems cheaper at first glance, but the true cost includes equipment, time, safety risks, and potential panel damage.

DIY Advantages

• Lower upfront cost (after initial equipment purchase)

DIY Disadvantages & Risks

• Equipment limitations: No access to deionized water systems or professional-grade cleaners
• Time investment: 3-5 hours of physical labor on roof
