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.
FAQ
How much maintenance do solar panels need?
Very little — yearly monitoring reviews and occasional cleaning. The main cost over 25 years is one inverter replacement.
What is the solar maintenance checklist?
Check monitoring, inspect panels/inverter/racking, trim shading, verify roof penetrations, and keep warranty paperwork current.
Does solar require professional maintenance?
Not annually for most systems. Hire help for roof access, cleaning on steep roofs, or warranty repairs.
