Things to Check First
- Look at the inverter display for an error code or warning light
- Make sure the isolator switches have not been turned off
- See whether the solar breaker in the consumer unit has tripped
- Look back at previous generation readings
- Look at the panels from the ground for cracks, debris or bird activity
Never try to open the inverter or work on the DC cabling: solar panels produce high DC voltages whenever it is light, even with the inverter switched off.
Typical Repairs in Harpenden
Most faults come down to a small number of components: burnt DC connectors, isolators damaged by water, wiring chewed by wildlife and occasionally a cracked or failing panel. High winds can also loosen mounting rails and lift tiles around the array, and it should be dealt with quickly to stop roof leaks.
