how much is your estimated yearly usage? 11kw array seems very big - thats a megawatt in a year. Although generally the more the merrier, a 5kw array + 10-15kwh battery would likely be better for utilisation of solar than solar only

I've gone for 14 Trina 390 panels, 9.5kWh Givenergy battery, 3kW inverter, Eddi solar divert - total of £12,250 including ALL required to fit, DNO, scaffold, etc. Ordered on 15 July and have a 6-8 week lead time. North Derbyshire/South Yorkshire area.
if not powering heating, a 9.5 should be enough in most cases other than winter, and its not clear that difference would justify another battery (although I’m also tempted I think I’ll just make sure the install is done and located somewhere I can put a second battery if needed in a year or two (eg when I add heating). I’d guess about 5k for another battery?
Our install via eon was finished today, apart from faff with the scaffolding, happy with it. Have set the inverter to eco mode and will see how it goes.
Thanks

Hence I said "might", as everyone's consumption and usage pattern is different.
Giveenergy 9.5kwh are around £3,200 wholesale. Interested to see how much installers are pricing them at installed.
Powervault, who are one of the few people even quoting right now, are talking about 8k and installation in mid 2023, with £750 installation fee.. Can't even get givenergy to give me a ballpark estimate of time or cost..
If £3200 is anything like the wholesale cost there's a huge markup right now.

is that inc vat? They’re supposed to be ‘almost’ DIY but recommend an electrician so if you have a location in theory should be max a couple hundred to install? Unless that also needs calibration/software updates.
Curious to hear who else has done it. But also - I might ask Eon as if thats ’just’ £3.5k extra might bite the bullet

There is now a possibility of power cuts in January. I know the Express can be less than truthful, but Powerwall users must be pleased that they should be well prepared.

FOUR days of UK power cuts and blackouts in January warning
THE UK is braced for four days of power cuts and blackouts in January, as part of a winter contingency plan.

Yes, I keep accidentally putting our PWs into Island Mode, and I just do not notice the switch or the changeover.

I read the same news from another source and this headline is (surprise, surprise!) being excessively alarmist.There is now a possibility of power cuts in January. I know the Express can be less than truthful, but Powerwall users must be pleased that they should be well prepared.

My understanding was that the government is preparing for a worst case scenario and IF it’s unusually cold and IF there is no gas and IF there is an issue with the DC interconnects to the mainland THEN MAYBE there will be the need to shed some load over four days in January, which MIGHT include domestic supplies.
I mean, bloody hell this hardly sounds like the end of the world and it’s perfectly reasonable to make contingency plans. In fact, it would be negligent of them not to (although since when does BoJo care about being negligent or not?)
Whilst the media do play a crucial role in ensuring political accountability (or at least they did), they do seem to be acting in increasingly more despicable ways. Bloody boils my piss.
That said….. my Powerwalls are at the ready.

Find a grain of truth, determine how far you can distort it without becoming indefensible, assess monetary value of running story based on extreme extrapolation..... Call it news.
It's the express, you start by assuming the headline is BS and work from there.
Indeed.
One's life can be massively improved by choosing not to read that lying, hate-filled rag.
Even more relevant today than it was in 2010....
Just finished building ground based install for 10KW - 22 JA Solar 455W panels, effectively 13m x 3m x 3m high sloping roof shed!
Have 8Kw Solis inverter. Tesla Powerwall with Gateway 2, 14 Kw EcoDan ASHP and 8 rads with Honeywell wireless TRVs under RHI scheme
Tesla Model S
House is 1850 Welsh cottage in the middle of nowhere, not looking to go off grid but would like to be as self sufficient as possible
Starting to think another powerwall may be needed

I got quite lucky in that the house I bought in Oct '21 has a 4kw solar array that was installed in 2013. They transferred to my ownership as part of the sale - so I benefit from some pretty good FIT scheme rates (currently get paid 19p per kw generated, with a 6p deemed export rate) - without having the initial outlay for installation costs. It's great to get the washing machine and dishwasher on when the sun is shining and not see any pull from the grid on the smart meter!
Even though it's only a 4kw setup, it's been a decent little bonus over these summer months. As such I'm looking at getting a Zappi charger, and would love a powerwall as well in future.
