    Spectrum energy recently installed an EV charger, solar panels and storage battery. I couldn't be happier with the service, communication and quality of the product. It's really user friendly with the customer app so I can keep up to date with how much solar I'm generating.

    Al and Vicki Holt

    Spectrum Energy Systems installed our home Aiko solar panels/LG battery/Solar Edge inverter and we have been really impressed with the level of service. The job was completed quickly, they responded immediately to any questions we had, and the installation was professional and thorough. The team was knowledgeable and efficient.

    Stephen Herring

    Highly recommended. I thought I would be better with a big established company (no names but eight legged sea creature). Spectrum Energy Systems came highly recommended and they've proven why. Spent ages on emails and phone calls with other companies sending information and when a surveyor eventually arrived found so many obstacles.

    Gail Liley

    I had two quotes and went with Charlie. He kept in touch and followed up with all my queries and getting to understand how everything works. Fitting the panels and equipment was very straight forward.

    I recently had a 4kw home solar system installed by Spectrum Energy Systems and I couldn't be more pleased with the experience. The team was professional, knowledgeable, and transparent. They thoroughly explained the process and benefits. The installation was efficient, respectful of my property, and completed ahead of schedule. Since installation, I've noticed a significant decrease in my electricity bills. Highly recommended!

    Brilliant company to deal with. From the initial chat about my requirements to installation, I can’t fault one thing. I found Solar somewhat a minefield with some people trying to bamboozle me with information but Spectrum helped explain it in simple terms. The installation was faultless and they even called me 2 days later just to check everything was running OK. 10/10 team. Would definitely recommend.

The installation was seamless, and the quality of work was outstanding. I’ve already noticed a significant drop in my energy costs. Plus, their after-sales support has been fantastic—they genuinely care about their customers. I couldn’t be happier with my decision to go solar with Spectrum!
