Solar Maintenance Checklist: What to Check Every Year

Solar systems are low-maintenance but not zero-maintenance. Here is the yearly maintenance checklist — panels, inverter, monitoring, roof, and warranty.

The yearly checklist

1) Check the monitoring app for production vs last year. 2) Inspect panels for visible damage, debris, and bird droppings. 3) Check the inverter screen for errors. 4) Look for roof penetration leaks or loose racking. 5) Trim trees that grew into shading.

What usually needs attention

Most systems need almost nothing beyond monitoring reviews for years. The first real maintenance is typically inverter replacement at year 10–15. Snow, pollen, and occasional debris are handled by weather or a gentle cleaning.

Keep your paperwork current

Document install date, equipment models, warranty terms, and monitoring login. When you sell the home or file a claim, this paperwork is what protects your investment. Some service plans (Palmetto Protect) bundle annual checks.
