Solar Panel Maintenance: The 3 Biggest Myths
Solar panels have no moving parts — maintenance is minimal. Annual visual inspection (10 min), cleaning every 1–2 years (garden hose + soft brush), and monitoring production via your inverter app.
Myth 1: Professional Cleaning Every 6 Months
False. Rain does most of the work. Professional cleaning ($150–300/visit) rarely pays for itself.
Myth 2: Snow Must Be Brushed Off
False. Snow slides naturally. Brushing risks scratching glass — scratches cost more lifetime production than a few snow days.
Myth 3: Panels Degrade Quickly
AGAIC BSM715 panels warrantied for 87% output at year 25. HJT degradation: ~0.5%/year vs 0.7–0.8%/year for PERC.
