Solar panel quote comparison

Powermalc

Good morning, first post as we are thinking of having solar panels installed.
We are in a 4 bedroom bungalow with oil fired boiler for hot water and radiators, no gas in our village, we do not want heat pumps or an EV.
We have sourced 3 quotes via a solar comparison site.

I would grateful if possible to get some opinion on whether these prices are reasonable with the equipment selected by the three companies.

1.
16 x Aiko gen 2 510w panels
Solax 7.5kw hybrid 5G inverter
Solax 2 x 3.6kw batteries
£10,000

2.
18 x Aiko 460w panels
Fox ESS K Series 7kw inverter
Fox ESS 10.36kw battery
£10,867

3.
16 x Aiko Gen 2 510w panels
6kw SigEnergy inverter
SigEnergy 8kw battery
£11,158

All include scaffolding and Solar iBoost for heating the hot water tank.

I can give names of companies if that helps and is allowed with forum rules

Many thanks for any input.

Welcome to the forum!

It's a bit odd that all three companies are quoting Aiko panels. They're not an especially common brand, judging from other quotes that have been shared here recently.

If I had to pick one from those three, I'd probably go with #2, with the bigger Fox ESS battery & inverter. But I'd want to know if they could fit 18 of the 510W panels rather than the 460W ones (the 460s seem to be the same width as the 510, but the 510 is slightly taller).

If you can stretch your budget slightly further, you might be able to get a Powerwall 3 system a bit like this.

For what it’s worth, the prices aren’t the problem- the component brands are 100% Chinese owned, all with little to none or poor track record. It is unfortunate that these are flooding the market. 

If it were my home, I wouldn’t install any of these brands.

It's worth mentioning that nowadays it's almost certainly not worth using solar power for water heating.
