We looked at batteries to compliment our pv array. At £8k the payback was 25 years

Yes, the financial payback on our installation is about 25 years, based on a capital cost of £35k for the complete system. But we're not doing it for financial reasons, it's more about energy security for us, we have a pretty bleak opinion on future costs and availability of electricity supply. And there's no point having money sat in the bank these days.

Thanks Tim.

I will be looking into them again so that is interesting.

Last time I looked, with the comparative low cost of electricity here, no Government subsidies whatsoever and the Jersey factor adding to the costs, there was no possibility of payback at all. Not the only point of course.

Although I can't access many of the alternative forms of energy, I use Bulb who promise to provide me with 100% renewal electricity and 100% carbon neutral gas.

Ground source heat pumps are expensive and disruptive, ideal for a new build or a major restoration.
We have an air source heat pump as auxiliary bedroom heating - and cooling in summer, otherwise known as an air conditioning unit.
I suspect that for the house heating a larger version may be an option, but it does mean upgrading all the radiators as the circulating water is not as hot as a gas boiler.

They are better suited to wet underfloor heating systems rather than radiators, where you want a warm floor over a large area rather than a red hot radiator with a comparatively small surface area.

Andy,

and that is the problem: gas heating for new builds is easy to design in, but applying new technology to old houses isn't easy.
We looked at the possibility of installing wet underfloor heating but the loss of ceiling height meant that we would be close to minimum room height.
So I hope that we will be able to convert to hydrogen for the fuel in a relatively conventional condensing boiler, keeping the traditional panel radiators.

Just got the FIT payment for June/September: £827.65.

Generation rate is 55.36p/unit,
Feed back rate is 3.90p/unit on 50% of the generated power.

This year should be over £2100 and since the start in November 2011 we will exceed £20,000 by the year end.

Surely the Generation rate is in pounds/Mwh? The wholesale price of electricity is currently around £25 on the day-ahead market. 55p/unit is £550/Mwh. The reason why they've stopped FiT is because it's bankrupting the electricity companies, but at 55p a unit they'd be out of business within weeks

The rate is 55p/kw/h... It is based on a 25 year Contract starting in November 2011 and is index linked to the RPI, so it goes up every year: it is also tax free.
If the commercial 24 hour rate is £25/mw/h then it is not at all surprising that the supply companies are bleeding cash.
The blame lies with the Government who wanted to incentivise the installation of solar panels. Wherever the calculations were made in whitehall there was clearly little understanding of the market for electricity or the way solar and wind power would take off.
Our contract is with EON. I am waiting for the day when they try to buy out the rest of the contract. I would take £45k. (16 years at £2000 with inflation)
