I'm not particularly posting good or bad news, just trying to give an accurate picture of the situation, which is that for the 1st 20 years of the installation the return will actually be slightly higher than if they'd used the 16.5p FIT + 3.2p export rates - it's certainly not worse than expected, which many might think at first glance.Sounds to me like clutching at straws desperately trying to find a glimmer of good news.
The benefit's very marginal. The export rate effectively has to be halved to account for the 50% deemed export, doesn't it? So the true figures are:
New: 16p + 2.25p = 18.25p
Old: 16.5p + 1.6p = 18.1p
I honestly don't see this being a significant issue for most of our customers. For most it's the initial rate of return and payback time that are most important IME, with a lot of comments along the lines of 'I doubt I'll live that long' etc when it comes to the total 25 year figures.The customer will barely notice the difference but reducing the duration from 25 years to 20 will typically cost maybe 500-700 per year in today's money for years 21-25.
I may be wrong, but I do see this reduction to 20 year FITs as being the least worst option when it comes to controlling the total costs of the FIT scheme, and it puts PV in line with most other technologies.
