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.
Highly recommended and a good price.Clean & tidy install. Very happy, thank you.
Amazing job from the team, very tidy and nice guys. Would recommend to all.
Keeping Your Solar PV System Performing Properly
A solar panel system can continue producing renewable energy for many years, but it should not be left unchecked indefinitely. Maintenance helps make sure your system is safe, secure and performing as expected. It can also provide peace of mind if you have moved into a property with existing panels and are unsure when they were last inspected.
Prometheus Electrical & Solar can check for visible issues, system faults, performance concerns and signs of wear that may affect long-term efficiency. We can also advise whether your system may benefit from servicing, repair work or additional improvements such as battery storage. Our aim is to help you get the best from your solar PV setup without making the process complicated.

When Should You Book Solar Panel Maintenance?
It is worth booking solar panel maintenance if your system is producing less energy than usual, showing a warning message, making unusual noises through the inverter or if you have not had it checked for a long time. Even if everything appears to be working, a professional inspection can help identify small issues early.
Maintenance is also useful after severe weather, roof work or electrical changes at the property. Solar PV systems rely on several connected components, so problems are not always obvious from the ground. Prometheus Electrical & Solar provides careful checks and practical advice, helping customers understand the condition of their system and what, if anything, needs to happen next.
Frequently Asked Questions
Helpful answers to common questions about solar panel maintenance.
Most solar panel systems benefit from a professional check every few years, although this can depend on the age of the system, the property and how well the panels are performing. If your system is showing faults, producing less energy than expected or has not been inspected for a long time, it is sensible to arrange maintenance sooner. Prometheus Electrical & Solar can assess your system, check key components and provide clear advice on whether any servicing or repair work is needed.
Solar panel maintenance can include a visual inspection of the panels, checks to key electrical components, inverter checks, performance review and advice on any faults or concerns. The exact work depends on your system and the issues reported. Prometheus Electrical & Solar takes a practical approach, looking for anything that may affect safety, efficiency or reliability. If we find a problem, we will explain it clearly and recommend the most suitable next step.
Reduced solar output can happen for several reasons, including inverter faults, damaged components, wiring issues, shading, dirt build-up or general system ageing. Seasonal changes can also affect output, so not every drop in generation means there is a fault. However, if performance has changed suddenly or noticeably, it is worth getting the system checked. Prometheus Electrical & Solar can inspect your setup and help identify whether maintenance, servicing or repair work is required.
