I have a suspicion this is merely one of many forthcoming "how to
manufacture domestic jobs, manufacture statistics and hide
statistics". All lined up for the "N% must be spent on green if an
extension built etc". All part of the creation of a manufactured
economy rather than a manufacturing economy, which USSR found failed
miserably.

Why PV are not economic...
- 2kW of PV's cost £5000 re Ebay.
- Annual generation say 1500kWhr, saving £150/yr @ 10p/kWhr.
- Payback of £3750 over 25yrs for £5000 outlay.

I'd rather a gov't negotiate a Bulk Buy of 2kW PV for £2500 and then
charge £2600 for people.
Instead we have a nonsense "sell back to the grid at 20x cost of
generation" which is a blatant "Welfare for Business" rather than
driving down the cost of PV through volume, quite shocking. Sharp no
doubt whinged loud enough.
