Excellent work...

"On time, on budget, professionally done and set up, including replacement of an inverter which was broken on arrival. Top of the line equipment used throughout."
BJ Thompson

Prompt and efficient...

"Jason did a great job of getting my PV array back working. I have recently taken over the array from another family member, so did not understand anything about it except that it wasn't working. Jason came, quickly figured out what the fault was, and fixed it with no fuss or bother."

Crispin Keable

Fantastic Service...

"Jason responded to my request for a second opinion promptly. I was "cold called" by a company offering a free check on my 6 year old solar energy system. They then tried to tell me the system was working at 72% capacity, that they would replace my inverter and install optimisers for £5,500 but special offer if i signed a contract there and then for £4,500. Needless to say I declined. I contacted Which? Trusted Traders for advice and was given Jason's name. He checked my system, found no problems and told me if anything it was performing better than expected."
