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.
