Same manufacturer, but a different panel. We got the JAM66S30-495w. Trying to figure out the difference apart from wattage and efficiency, whether the JAM72s are older or newer. Really hard to find comparison info.
They installed 10 495w JAM66S30-495/MR solar panels, but I think they've been superceded by a 505w one now. The Inverter is a Growatt, think it's the 750-3000s, but not 100% sure. I expect I could've gotten more expensive tech, but I had a budget and that's the best that seemed to come up time...
A company called Skylar, based in Essex, but they install all over, they've done 3 houses in my street in W.London. Sure you could find a local independent as well though.
Our main roof faces slightly South South West and has a velux window in it, so they could fit 6 panels on there, but as the installer said, the panels are cheap (roughly £150 each), it's just installation and the inverter that cost the money. He said get as much as you can on the rooves, so...
We signed up to the one in London earlier in the year and tbh I don't think it matters how many sign up to it, you'll get a bog standard third off from whichever company wins the contract. They give you a rough estimate of what a couple of systems will cost you and then you have to pay £100...
