 Trustindex verifies that the original source of the review is Google. We had a very prompt response from the firm in answer to our inverter being off line. Josh came out to help with our sunsync inverter. He was cheerful, polite and very respectful of our home. He was extremely patient in trying to resolve our issues and due to the sunsync platform being down he had to come the next day to resolve our issue. He successfully sorted out our problem and we were only charged the one call out fee. I would definitely recommend this firm and Josh in particular.

Does Cornwall get enough sun for solar panels to be worthwhile?

Absolutely. Cornwall is the sunniest county in the UK, and Truro and St Austell sit right at its heart. The TR and PL postcode areas average between 1,600 and 1,750 sunshine hours per year — significantly above the national average. Combined with modern monocrystalline panel technology that generates electricity from diffuse daylight as well as direct sunshine, solar is one of the strongest long-term investments a Cornwall homeowner can make.
