# Solar Panel Maintenance Guide

Solar panels require very little maintenance — but a few simple steps will keep your system performing at its best for 25+ years.

## Maintenance Tips

### Visual Inspections

Check panels twice a year for debris, bird droppings, or damage. Most issues are visible from ground level.

### Cleaning

UK rain keeps panels reasonably clean, but annual cleaning can improve output by 5–10% — especially on low-pitch roofs.

### Inverter Monitoring

Check your inverter or app regularly for error messages. Modern systems send alerts automatically if something's wrong.

### Professional Servicing

A professional health check every 3–5 years includes electrical testing, connection checks, and performance analysis.

## What's Covered by Warranty

30-year warranty

10-year inverter warranty

10-year battery warranty

Workmanship warranty
