- Clean regularly — dust can cut output by 15–25%. Use soft water and a non-abrasive mop, early morning or evening.
- Watch your app — a sudden drop in daily units usually means a fault.
- Trim shade — growing trees and new structures reduce yield.
- Check inverter lights — any red/fault indicator needs attention.
- Inspect cables — look for rodent damage or loose connectors.
- Test earthing yearly — essential for safety.
- Get an AMC — professional checks and thermography catch hidden issues.
