Solar panels and battery - any real world recommendations?

Thanks all for the feedback upthread. I've got two further quotes which both come in around the £10.5k mark for a similar system. The caveat with both is they are desktop quotes so subject to them doing proper surveys. I've asked for quotes for a Tesla system out of interest. Nearly £7k is a huge saving though, and would help both with funding it and the breakeven time.

The Tesla is appealing as we had a power outage for half a day earlier this month so whole home backup would be a big asset.

check the switching times for Tesla PW3, believe it is multiple seconds (spec sheet not clear), which would not be good enough for some applications. Hence for us, we chose the sigenergy gateway, which is 0ms and have tested it out. (servers)

I don’t think I need anything instant, we have nothing critical, but the ability to access the internet and use our laptops is pretty crucial when WFH.
 
Tesla PW is 20ms which is the EPS standard, same as GivEnergy. It is fine for everything except some computer equipment which may reboot. It’s certainly not several seconds.

Sig is fast enough to technically be UPS but it’s not a true UPS like you’d get in a computer server, it’s still switching in the power rather than being always on.

Thanks had seen pw3 users quoting ranges but could not find in spec sheet

We have sigenergy kit, It is definitely fast enough for me. I run servers at home and we get frequent power cuts, since install we have had two, Not even a light flicker in the house!
 
My opinion of Artisan Electrics is really going down hill, they are now saying utter rubbish on their channel, how can they be so poorly informed???

Yup, I watched it and looked at the comments where they were suitably roasted on the dodgy information on exports.

EDIT - that house has a big array so they could be hitting up against an export limit wall but, and it is a big but, spending £1500 on an EV charger is a lot of 8p's to make up (15p export less 7p import).

EDIT2: not sure why they bothered removing the Garo unit and replaced the cable run, it should have just been a straight swap.

Went downhill when Cory left. I stopped watching him after that.
 
Hi guys, I've recently had a quote from heatable -

Solar panel
15 × 440W REA Power FUSION 2 · REA-HD108N-440
Inverter
15 × Enphase IQ8HC-72-M-INT · 380W
1 × Alpha ESS SMILE-G3-B5 · 5000W
3 × Alpha ESS SMILE-G3-BAT-4.0S · 4kWh
1 x Alpha 7kw Charger

This is £15,200, seems steep to me. I'm interested in some interest free finance options and they are semi local to me.
Any help much appreciated, cheers Chris

I've managed to lock my old account chrisnic0 from 2003 just trying to recover!

It is very steep, you also want to be fitting as many panels as possible.

I'm not a fan of Heatables, the heavily push very expensive panels, they also up sell the fact they ate bifacial, which when fitted 100mm off a roof will have next to zero benefit.

Unless you have shading issues micro inverters aren't required, and due to way they work, when adding a battery you get great efficiency losses.

I'd suggest giving Spectra Solar a call, many people on the forum have used them and been impressed, they are not far from you.

Why have they offered three 4kWh batteries when Alpha ESS do a 10kWh G3 battery?

It's a very expensive quote in all honesty. £15k is Powerwall 3 money and you'd get more storage, eps and more mppts if that's the reason they have specced enphases.

440w panels is a bit stingy too. 460w aikos are available now in the standard size for less than £100 each.
 
it is expensive but they claim the setup would generate more energy which seems to stack up.

However, that’s a lot of 15p’s when you are talking about spending thousands more on a system. Not sure the maths works.

Very pricey indeed!

I recently had installed
20 x Aiko Neostar 2 455w solar panels
10kW Sigenergy inverter
2 x 8.06 kW Sigenergy batteries
Sigenergy gateway which controls whole home ups backup.
This was all fitted for £13,300

Do you have any shading on the roof? If not then you won't need the Enphase micro inverters which is a big saving.
