Great service from Chris and his team.
They installed solar panels and battery on a day with heavy rain and did not stop until it got dark with the final connections done first thing the following morning. Chris explained how everything worked and said any problems or questions just contact him anytime.
We had an issue with the system connecting to the app the following week and after a quick phone call Chris came out that same evening to sort out for us.

Fixing Faulty and Underperforming Solar Panels
A solar panel fault can be frustrating, especially if your system is producing less energy than expected or has stopped working altogether. Some problems are obvious, such as warning lights or inverter error messages, while others may only become clear through reduced generation or changes in monitoring data.
Prometheus Electrical & Solar can help investigate solar panel faults and identify what may be affecting your system. This could include problems with the inverter, wiring, isolators, panels, connections or the way the system is communicating with your monitoring app. Once we understand the issue, we can explain the repair options available and help you decide the most practical way forward.

When Should You Book a Solar Panel Repair?
It is worth booking a solar panel repair if your system has stopped generating electricity, your inverter is displaying a fault, your monitoring app is showing unusual output or your energy production has dropped unexpectedly. You should also arrange a professional check if you notice damaged components, loose wiring, water ingress or signs of wear around the system.
Leaving a fault unresolved can affect performance and may create further issues over time. A professional inspection can help confirm what is wrong and whether the problem can be repaired safely. Prometheus Electrical & Solar provides clear advice, careful fault finding and reliable repair support for solar PV systems across Swansea and the surrounding areas.
