The most common issues with solar PV systems
It's ultra-reliable but even solar PV systems can develop faults. See the list below for the most common issues or faults encountered
1
If the meter is off entirely, with no visible display, it's either failed, or, it has no mains power. Check the consumer unit with the RCD and MCB (fuse) for the solar circuit
2
The inverter is the work-horse of the system and generally can be expected to last around 10 years or more. They occassionally develop faults before this and will sometimes show a red fault light or error code on the display
3
Solar panels very rarely fail within the 20 year or 25 year expected lifetime of the system. Connections between panels and loose cabling is the more likely cause of an array fault
