Rob666 What persuaded you to go with the other one? I’ve just signed up with the local “Solar Together” scheme to see what they can offer.
Both offers were similar in price and specs, and the E.ON one also had branded components (good panels, GIveEnergy inverter and batteries). I would happily go with either, but I only have one roof. I think what eventually tipped it for me were some psychological reasoning: Solar Together scheme does a tender and chooses a local(ish) company. The chosen company had good reviews and their website made a good impression. I also thought that because it’s a group buy, maybe they are offering better value to the group because of scale. In addition, they had the backing of the local authority.
E.ON also made a good impression, but with them you don’t know which local installers you will get (they work nationally, but don’t install the systems themselves). I also preferred to go with the smaller, specialised local company than the multinational corporate.
I’m pleased with my choice, and obviously can’t say much about the offer I didn’t chose, but had I not had the Solar Together option I would go with E.ON, and I have no reason to believe it wouldn’t be good as well.
Here is the quotation from E.ON. You can see that the PV array is slightly bigger than what I got and the battery slightly smaller. I have another quotation with 9.5kWh battery which came up at £10.989. With E.ON you can also pay over 36 months with no interest:
