5.0

Spectrum Energy Systems Ltd installs solar panels, batteries and EV chargers for homes, theatres and commercial sites. One customer said Charlie Fletcher handled a three-phase solar and battery job from the first questions through to sorting out a fault afterwards, and another said he came up with a workable design when other firms had found problems. Several reviewers said the team explained the system, kept in touch and answered questions. Others described the installs as tidy, courteous and done on time, and one was pleased that a design kept the roof neat rather than running cables over it. Some reviewers had minor issues sorted quickly, while one said they got no reply from a different firm they had used.

Long overdue, but thoroughly deserved. 5 stars for Spectrum Energy Systems. This review is a couple of years late, but the quality of the work has stood the test of time, so it's worth writing. Charlie Fletcher installed our three-phase solar PV and battery system back in September 2024 and was outstanding from start to finish. The price was very competitive and the service was even better. Charlie took the time to answer every technical question properly before we committed, and when a teething issue with the system cropped up right after install he was straight on it. He came out to site, chased the manufacturer himself and got it resolved quickly without any fuss. What really sets him apart is the care taken in the finish. The cabling is neat and tucked away rather than draped over the roof like you see on so many other installations. He clearly takes pride in the job and went the extra mile at every step. Highly recommended. Honest, knowledgeable and does the job properly.

We thoroughly recommend Spectrum Energy Systems to anyone looking to go the solar route. Having ploughed through the internet looking for suitable suppliers/installers, we opted for 4 including spectrum energy systems. Our initial contact with spectrum energy systems led to a telephone conversation with Charles Fletcher and then a subsequent site visit. Charlie explained everything that Spectrum could do for us, approximate costs and length of installation. Charlie then supplied a written quote and product details of solar panels, inverter, batteries and I solar solar boost. The quote from Spectrum energy was the most competitive of the 4 we got and best value for money when comparing the products they were installing. The electrical and mechanical installation teams turned up as agreed, and were very courteous and respectful of our property. Full installation went smoothly and Charlie visits again to commission and explain how everything works and helps download an app to phone so you can see where the energy you produce goes to. If you’re looking to go solar the I can’t recommend enough the team at spectrum energy systems.

An excellent service from Spectrum Energy Systems Ltd who fitted solar panels and battery to our home when others said it was impossible. We are delighted with the system and especially the high quality of personal service and support from the whole team. We have no hesitation at recommending their work.
