I've had a quote back but I think they want too much:
3.9 kw system (10 * 390w Trina panels) with no battery - £5.8K (string inverter) or £6.4K (solaredge inverter).
Same as above with string inverter + 8.2kwh Givenergy battery - £9.8K
Same as above with string inverter + 13.2kwh powerwall - £15.6K
That sized solar system vs cost seems overpriced for just 3.9 kws, and the battery quotes don't seem great either.
Still pending a quote back from someone else. May need to seek a 3rd or 4th opinion. I'm definitely wondering if the gov will put forth some incentives in the next year or so to cheapen the installs a bit.
I actually think this might be the best move! 2 batteries in tandem, enough capacity to charge up overnight on a cheaper off-peak tariff, predictable energy costs all year round.
I wonder if this also means you don't have the same levels of paperwork, and the DNO things etc as well, after all it's just some batteries on site![Smile :) :)](/styles/default/xenforo/vbSmilies/Normal/smile.gif)
16kwh or so should be enough to basically go the whole day, assuming smart about usage.
Powerwall is interesting as well because it lets you use the Tesla Energy Plan - obviously it's a huge cost, but with the TEP you appear to get the same import and export rates all the time, and it turns your whole house into a giant UPS basically. https://www.tesla.com/en_GB/support/tesla-energy-plan-faqs?redirect=no - huge investment though and still a multi-year payback, especially as you need panels.
Indicative pricing of Tesla plan is very good, you get more for generation, but unit rates are a bit higher than pure off-peak charging.

I know someone who has just had 15kWh of batteries installed at only £5.7k including inverter and charge controller etc. Costing him £1.12 to charge vs £4.50, so a saving of £1233 per year based on the peak rate at 30p, he uses about 19kWh a day but it's trying to reduce some peak use and shift that as well.
