Quick answer
Most homes clean panels one or two times per year, or when monitoring shows soiling losses. Dusty or pollen-heavy areas may need more. Quality panels often produce for 25 to 30 or more years with slow yearly power loss. Inverters and other electronics may need attention sooner than the glass.
Maintenance is where ownership gets real. The shiny install day ends. Then you live with monitoring apps, weather, and the occasional “why is production down?” moment. This hub gathers the practical guides so you do not learn roof safety from a random video.

Simple ownership habits that protect output
- Check the monitoring app monthly for sudden drops, not only daily weather noise.
- Compare this summer month to the same month last year when you have history.
- Clean only when dirt is obvious and access is safe.
- Skip pressure washers and harsh soaps.
- Hire help on steep, high, or fragile roofs.
- Keep guarantee PDFs, model numbers, and as-built layouts offline too.
When to call a professional
