Solar panels are fairly low-maintenance, but they do need occasional attention. A quick wash a couple of times a year and a yearly professional inspection help maintain efficiency. Watch for cracked glass, loose wiring, or hail damage; small fixes cost far less than waiting until output drops. If a panel is badly shattered, replacement—handled by a licensed pro—is often the smarter call.
Most panels last 25 to 50 years, so replacement is rare. Swap them out only when output drops noticeably, the warranty has run its course, or storm damage makes repairs impractical. Track your production data; if efficiency continues to slip even after minor fixes, it’s time to consult a solar installation professional and consider replacing a panel.
Homeowners are accountable for solar panel repairs unless their system is under a leasing agreement. Warranty coverage may reduce repair expenses for specific components. Warranty protection covers repairs when panels fail due to installation errors or unexplained issues. However, if a unit cracks due to an impact, the homeowner is responsible.
Always contact your installer and review your warranty before initiating repairs. Many manufacturers offer warranties ranging from 10 to 20 years. Inverters have a 10-year warranty, panels carry a minimum five-year workmanship warranty, and the overall system is protected for 25 years.
