Low solar power generation is not always an inverter problem. Damaged MC4 connectors, failed bypass diodes, cracked panels, faulty DC cables and string fuses can all reduce output. We find and fix faults across the full solar PV system.
PV system faults we repair
- Burnt or loose MC4 connectors
- Junction box and bypass diode failures
- Hot spots, cracked cells and damaged panels
- Earth faults and damaged DC cables
- Blown string fuses and faulty DC combiner boxes
- Under-performing strings due to mismatch or shading
Solar panel power generation problems
If your solar system is generating less than before, we compare string-wise output, scan panels with a thermal camera and test the DC side, then fix the specific panels or connections responsible.
Frequently asked questions
Why is my solar panel generating less power?
Dust, shading, damaged connectors, failed bypass diodes, degraded panels or a faulty inverter MPPT channel can all reduce output. String-wise testing identifies which one it is.
