Wanting to augment my existing system to include battery, additional panels & an EV charger, I used the Solarquotes facility to request 3 quotes from local installers. I received two quotes within 10 days which gave me enough information & confidence to seek another two quotes from installers via my own research. I've made my purchasing decision and am looking forward to being energy self sufficient (well, mostly anyway). One improvement, if I may suggest, is to ensure the installers receive the brief & photos entered as part of initiating the quote. I provided a reasonably detailed but concise brief, however the installers either didn't receive that information or didn't read it. All in all though, thanks to Soalrquotes for helping me to get going
