The usage of charging the batteries would be well within normal usage for an EV to be fair. The main issue will be whether they start asking for proof though I suppose.but if kicked off the tariff (no EV) then the batteries on their own are pointless too

Bulb don't require an ev, but rumour is they are being bought out by octopus.The usage of charging the batteries would be well within normal usage for an EV to be fair. The main issue will be whether they start asking for proof though I suppose.
They have a tariff for batteries but I think you need solar too unfortunately
HiHas your solar installer not quoted you?
It'd a real shame such a new system didn't raise at least the idea of adding batteries later, a hybrid inverter doesn't cost that much more.
You'd think if they had any inclination to fit batteries they'd have used the right inverter. Don't get me wrong, batteries are very highly priced right now, but that seems wrong.Hi
Thank you for your help so far, when I first inquired regarding a battery the company who supplied the panels said a battery was not needed and a waste of money, since accepting the quote I asked someone else who had solar panels and they said it was good to have one. When the panels were fitted I askEd the company about a battery, they said that they had no stock and to wait until next year when they were cheaper.
My (very vague) calculations were...I've been unable to locate it, but there was an article in The Guardian that looked at the merits of various installations, and the viability thereof, what must have been a few months ago now.
One of the points raised re batteries was that the effective 'life' of the battery vs the cost of them meant that it was pretty on the edge as to whether they were worth it.
You could end up spending thousands on a system that conks out way before it pays you back, so i wouldn't worry too much about it if it is otherwise doing the do.
Thats one I contacted and never heard back off, could possibly be the one that contacted me last week but they're a month late.
My payback period is currently between 6 and 7 years, for my battery only system (which I'm still waiting for the installation of said system). It was lower before the government introduced the EPG (Energy Price Guarantee), and it may well come down again when the EPG ends.My (very vague) calculations were...
A battery has a 10 year warranty and is rated to still be at 80% after 6000 cycles or 10 years, for ease we'll say 90% at 5000 for the whole duration.
The average cost of a fully installed battery is $500/kWh. (I say $ but only as I have no quid symbol on this keyboard!)
Therefore a 10kWh battery costs 5k and does 5,000 cycles, so a quid per cycle
Each cycle is 9kWh, so 11p per kW cycle
So basically your battery, if assumed to be junk at 10 years, costs 11p per kwH you use from it.
Next you need to look at how it's charged, it's free if from solar, but you'd get the SEG if you didn't use it to charge. That used to be a measly 4p, you're much better keeping it in a battery til needed as it 'costs' you 15p per kW saving roughly 1/2 (battery plus lost SEG).
Octopus now offer 15p, that changes things a bit as each unit stored now costs you 26p, while it's still better than the 34p you pay for incoming energy it means you only save 8p per kWh (roughly 1/4).
All this changes drastically if you have a night time 7.5p tariff of course, as then you can top up all winter for 18.5p (11p battery cost plus 7.5p tariff) meaning you can keep the savings going even without solar generation.
My view going in was the system must pay itself back within the warranty period, even though it's expected life is much longer.
Odd, he was very on the ball with me. Was it Lawrence who came out or someone else? And did they actually give you a quote, or measure up then were meant to be sending you one?We haven't had a call back from Green Logic after they came to quote last Wednesday...
They sent a quote, but we were expecting a call back from the boss as we wanted to discuss some bits. I would have thought they'd have followed up to see if the quote was acceptable and get us booked in. I think the fact we needed planning permission may have scared them off.Odd, he was very on the ball with me. Was it Lawrence who came out or someone else?

EDIT: Just checked and mine came from proposal@opensolar.com is that helps?
Strange, could have at least said no they can't do it!They sent a quote, but we were expecting a call back from the boss as we wanted to discuss some bits.

Once again thank you for your advice it has been very helpful, I have just found this offer https://lr-renewables.co.uk/product/growatt-6-5kw-battery-storage-bundle/ reviews for the company are good on Trustpilot, my only concern about Growatt is their software is not the best?My payback period is currently between 6 and 7 years, for my battery only system (which I'm still waiting for the installation of said system).

The wind farm I have purchased a share in, which starts generating next year, will pay back in around 3 to 4 years (from when it starts generating), based on current prices.
Once I have my batteries installed and the wind farm is generating, based on current prices, I expect to be consuming electricity at a little over 7.5p per kWh and producing at 15p+ per kWh which, hopefully, will more than cover any standing charges.
Then I can turn my attention to my heating. My current consideration is to do a straight swap, that is removing my gas combi boiler and installing one of the new Tepeo 'night storage' combi boilers, which are due on the market next year.
You do when you live in a conservation area.Strange, could have at least said no they can't do it!
I didn't think you needed planning permission for solar?
I had a lot of 'no responses' when trying to get quotes; the decent solar/battery companies have, mostly, been swamped by demand outstripping supply. I expected the lead time for my own installation to be in the 6 to 9 month range; hopefully, not too much longer for me now.Once again thank you for your advice it has been very helpful, I have just found this offer https://lr-renewables.co.uk/product/growatt-6-5kw-battery-storage-bundle/ reviews for the company are good on Trustpilot, my only concern about Growatt is their software is not the best?
Also the company from Derby never responded to me either.
