Hi All,

Hoping for a bit of clarity about the quotes we've had. We spoke to 3 installers, a local guy, a family run company and a large company.

All seem to have decent reviews across the board but where I expected they'd all roughly solidify on a specific setup, they've confused the matter more!

I'm looking for input if you would be so kind on the quotes?

The first 2 quotes suggested splitting the panels 6x South Facing, 6x West Facing. The last 2 quotes when discussing with the guy, he seemed surprised they suggested West as the east facing clearly gets more sun overall (He used a satellite view heat map overlay) and he was right, not by much but enough that makes a difference. He then said if we can afford it, he would recommend doing 6 on each of the 3 facings.

Our daily usage averages 8kWh a day across the year (not including the EV). So I don't think we need the 18 panels, but are we better off doing that now and future proofing? He did say he was happy to provide a quote for 12 panels instead of we preferred.

I've not heard of Hanchu, Hengdian or Dyness so not sure what sort of "quality" they are or any pitfalls? I have heard of Sigenergy, so tempted to lean towards those quotes...

Whilst getting our first quote, he asked about our preferred battery location.

Our house has a garage built into it, so it's on the front left, with one of the bedrooms above it. The consumer unit is in the garage on the back wall and the electric meter is on the outside of the sidewall on our access passageway.

I queried the garage as a potentially location, which he advised against due to insurance companies starting to get funny about having them in the house, but the passageway is too narrow to fit them and still get bins past. After discussing he advised to use the garage but to add a fire sensor linked to our smoke alarms.

It got Me thinking though, is there anything that stops them having the batteries on the opposite side of the house (We are detached and that side is just wasted space)? It's a longer cable run, as it'll be on the opposite side from the meter and consumer unit, but is there anything stopping it/any issues?

Hi All,

Looking to start my solar journey hopefully. We've got a quote from a local installer who has good reviews, been around for a while and seemed friendly/knowledgeful.

We're looking to get more quotes though and these two companies seem to have decent reviews and been around a while. I wondered if anyone had any direct dealings with them?

Thanks,
