Solar panels and battery - any real world reccomendations?

got some final quotes from people i have 3 phase at home.
48 x Jinko Solar Co., Ltd. 440 Watt Panels (JKM440N-54HL4R-B)
1 x SigenStor EC 17.0TP (Sigenergy)
3 x SigenStor BAT 8.0 (Sigenergy)
48 x TS4-A-O, 1 x HomeMax TP
£21k installed

23 x Trina 445W solar panels
Fastensol pitched roof mounting system with Bird Guarding
GivEnergy 11kW 3ph Hybrid PV Battery Inverter inverter
6 x GivEnergy 3.4kWh LiFePO4 High Voltage Stackable Batteries
£20.5k installed

I am still waiting on my quote from Artisan Electrics funny, they came out in August them called me in November to ask if i still wanted a quote but it would be a couple of weeks more and still nothing. I had some more work done on roof so held off others but not all done can go ahead.

This certainly seems the better option, be interesting to see what Artisan come up with, so much for good service through.
 
The 48 panel 3 phase will be some system, you ll take over top place on production on this forum for sure.

A friend of mine is currently having a similar system installed utilising sigen batteries.
 
Quote Check please, had a few and this one is the best I think but wanted to check.

Average yearly usage is 7400kWh, daily average around 19kWh, plan to get an EV early 2026. Wanted to max my roof space now rather than later.

14.560kW System
32 x AIKO-A455-MAH54Mb/2S - (16 South, 16 North)
2x FoxESS EP11 Total: 20.72kWh (kit to be installed in Garage)
Fox ESS 1 x KH10.5 - 10.5kW of Inverter
Scaffolding included
MCS certificate included
Bird Mesh
G99 included
£14,750

Thoughts?

considering I’ve seen Tesla and 28 panels for between 14-16k that seems reasonable. Hope that goes well wished they’d do that install for me in the south.

That looks to be a very good price (amazing how much cheaper it is now) and an ideal choice of inverter aswell. The batteries can charge/discharge continuously at 10kW too, but I would check if they could install the new EP11-H if you're having them in the garage as they come with built in heaters.

Should be good for over 10,000kWh per year. The north panels will generate about 60% of the south-facing ones.

Thanks, id like to also maxmise exporting too, try get every last penny out of this system.

according to https://garydoessolar.com/utilities/dailymodellingutility/ the battery can fully charge in 5 hours? is this correct?

ive just moved to Tomato Lifestyle tariff which gives 5 hours at 5p per kWh so this should tie in nicely

It's split on both sides of roof so not all best. Still wondering if there's something else I should look at cheaper but seems 3 phase options this is good but expensive.

The EP11s can charge at a rate of 10.3kW, so you could fill the entire 20.7kWh of batteries in a couple of hours. As I said though, this will be slower in cold weather so some form of insulation or the EP11-H with built-in heating would be helpful on the coldest winter nights.

IIRC they don't offer an export tariff, so you'd need your export elsewhere, and that possibly won't give the best export rates. Octopus for example only pay the basic SEG rate of around 4 or 5p IIRC unless you have import with them. You really want to maximise export payments, especially for the summer. I fully charge on Go overnight, and export what is left after 19:30, getting down to 15% SOC by midnight, then recharge between 00:30 and 05:30, and export is paid at 15p per kWh.

We have the sigenergy system very similar to you spec. Is the gateway being specced in yours or not? We have 40 aiko panels 3 x 8 kWh sigenstor, gateway, 10 kWh inverter. Slightly less cost for us but we have less panels. Three phase prob adds more also?

Artisan were like this with us. Sooo slow and the sales chap, well seemed off the pace of everyone else. They finally made contact after we had finished our system, months for a call back.

Have gone for this today. I double checked the EP11 they quoted was the heated one as the quote just said EP11 and it was. They are going to amend the quote so it’s clear.

The EP11-H cost an extra £200 each over the standard EP11 So delighted with this!
