What our clients say

We had a 6Kw solar system installed by Big Green Solar when the energy companies first started putting their prices up. Their workmanship and knowledge is second to none. Would definitely recommend.

Mr Beacon, Blackwood

I can highly recommend the team at Big Green Solar to fit solar panels and battery storage. From initial contact through to handover, they were a pleasure to deal with. We expanded our solar array and added battery storage and are very pleased with the results. 

Mr & Mrs Davenport, Cheltenham

Thank you Andrew and all at Big Green. I’d been looking for a company that could survey my property’s suitability for solar AND make recommendations for the best system to suit my needs. I ended up going for a Solax system which is performing brilliantly.
