Solar power systems are highly reliable, but like any technology, they can develop faults over time. Especially in the harsh UAE climate with extreme heat, dust, and sandstorms, regular monitoring and maintenance are essential.
At Watts & Ergon, , we frequently help customers diagnose and fix solar system issues. Early detection can prevent major energy loss and extend the life of your investment.
| Fault | Main Causes | Common Symptoms | Impact on Performance | Recommended Solution |
|---|---|---|---|---|
| Soiling & Dust | Sand, dust, bird droppings | Sudden drop in daily production | 20–40% loss | Regular cleaning every 2–4 weeks |
| Inverter Failure | Overheating, aging, grid issues | No output, error codes, shutdown | 100% system stop | Firmware update, professional repair |
| Panel Hotspots | Shading, cracked cells, dirt | One area of panel very hot | Permanent panel damage | Thermal imaging inspection |
| Wiring & Connections | Loose terminals, corrosion | Intermittent power, burning smell | Fire risk & energy loss | Annual electrical tightening & check |
| Shading | Trees, new buildings, poles | Drop in output during specific hours | 10–30% loss | Trim vegetation or redesign layout |
| PID | High humidity & voltage stress | Gradual power decline across array | 10–30% long-term loss | PID resistant panels + proper grounding |
| Battery Problems | Over-discharge, poor ventilation | Reduced backup time, error alerts | Poor energy storage | Regular battery health check |
| Ground Faults | Water ingress, damaged cables | System shutdown, safety trip | Complete shutdown | Immediate professional diagnosis |
