DECC launch FIT review

[whinmoor]

Has anyone modelled how the finances will stack up on a 4kW system generating 3500 kWh p.a?

My rough notes suggest that a lot depends on in-house consumption. If, and it's a very big IF, the householder can use 50% of generation at 14p per kWh, then you're looking at:

Generation tariff (1.63p) = £57
Export tariff (4.85p on 50%) = £85
Bill savings = £245

Total = £387

On a £5000 install cost, this looks like an 11 year payback.
On a £4000 install cost, it's about 9 years.

Does this look right?

Jesus wept. I was worried, but didn't expect this.

At least I won't have to worry about next years 3 day long MCS paperwork exercise.

Perfect roof, 5k - 11.6 years for us, not that we could install anywhere near those costs
4k - 9.8yrs

Yes, clearly worse the farther north you go. It's going to be a very difficult sell to customers. Maybe a chance to get involved in upselling storage solutions for those who survive?

Wonder how the R-a-R companies are taking this announcement? That's their whole business model screwed over.

Actually I calculated it wrong - it's 14 years and 16 for E/W! I suspect RAR will have done very well for the last 5 years and it's time for them to retire now.

And lets be honest, perfect roofs aren't exactly that common. Especially with a straightforward install.

Okay, lets assume that the cuts do go ahead and that material costs remain pretty much where they are now as well as fuel costs. Can anyone see a future in the industry at all?

Anything but pretty much south and unshaded is looking at 15 years plus even for a good value install.

BPVA finally get off the fence.

I wonder if a united industry will be any more effective at challenging these proposals than it was when the gov were able to divide and conquer.

There is another nasty wrinkle associated with the quarterly cap.

The change will mean that the EPC issued for the property will have to be dated before the installation's commissioning date rather than on or before the eligibility date as at present.

This means that the PV itself can no longer be counted towards the building's EPC. The required level will have to be achieved without it.

This is separate from the future potential change of increasing the requirement from a band 'D' to a band 'C', by which time the FiT will probably be less than 1p per kWh in any case.

The other element I don't understand is why DECC are talking about compulsory notification to the DNO being part of the FiT eligibility requirement when this is already effectively covered by the G83/G59 rules under the ESQCRs anyway.

132. DNOs are looking to manage these impacts. One area of concern is that DNOs are not currently routinely receiving notice of new installations, where no work is required by them, e.g. those on domestic premises. This means that DNOs do not have sight of all the generation connected to their network, which hinders their ability to develop and deploy of solutions that increase network efficiency.

Are large numbers of installations really not submitting the G83 paperwork?
