End Of Solar Subsidies
Posted 31 August 2015 - 09:52 AM
Initially is was set up with a FIT rate far too high. We had just about reached the point where is was about "right" i.e you get paid for what you generate at about the same rate as what you pay for what you consume.
After the end of the year we will have a system that pays so little or nothing at all that nobody will bother with solar PV any more. In a stroke the government has killed a whole renewable industry, made thousands unemployed, and stopped take up of a really good green energy source. Well done that government (can't make up my mind which is the ironic smiley)
Perhaps in a few years we will see viable low priced systems that incorporate storage. Until that point it will become just the realm of the dedicated tinkerer who wants to devise their own storage arrangements.
the solution is blindingly obvious to anyone whith more than two brain cells. Net metering. no subsidies, no payments, but simply if you import you pay, if you export, the meter reading goes down, so you only pay the difference. But that's far too logical to even get considered so will never happen.

This developer would have had to build better houses with no FIT, I believe, as it wouldn't then have been cost-effective to fit PV on the roof of every one. I suppose the flip side is that they are marketing these houses as being "eco" and are raising the awareness of having PV on every roof (it's a pretty big development, several hundred houses). Against that, it wouldn't surprise me to find that the PV is effectively "rent a roof", with the developer getting the FIT....................

I understand what you are saying about government killing off a sector. However this was on the basis of a subsidy (which we know this government cannot afford).
The question now is how this could spur innovation. Could technology and manufacturing advanced to a point where a solar PV system (with energy storage) would cost £1-2K to install and would pay back in 1-2 years. Wouldn't people clamor for it, regardless if there is no subsidy or FIT?
I'm dreaming of having a mortgage free house where I don't need to spend a cent on electricity and water. All I spend on is on council tax, internet and food. I can retire early and focus on quality of life.

This combined with the money being poured into battery research by the car makers may combine to drop the cost of solar PV + storage dramatically over the next few years - but there are still some big problems to be overcome so don't hold your breath.

A system where you pay for the panels and install and just get paid a fair rate for what you export. Where's the subsidy in that? other customers pay to buy that electricity.
What we will end up with is a system where you pay to install a system and then give away the electricity for free. tell me how that is "fair"?

Without an export meter the equation
usage = import + generation - export
has 2 unknowns.
That's why we took up the offer of an export meter back in the days when SSE had it as a tick box option on the FIT sign up form.

My view is that micro generation should never have had any incentives to install, it really distorted the market and meant that there was no coherent plan.
A few years ago, net metering was being talked about, but people with renewables wanted to get paid what they imported energy at. This is a nonsense as it does not take infrastructure costs into account. I notice that on my latest bill, network costs are 24%. So for every unit I use (on average as I have E7) I pay 2.17p for transmission.
The wholesale cost of my energy is about 3.8p/kWh.
So taking one from the other, we should be paid about 1.7p/kWh for exports. About what is being offered.

Thing is that prices vary during the day. So should you be paid of the half hour price or on what your retail charges you.
If it was on what your retailer charges you, you would have the odd situation where some people with PV (net exporters) would be demanding higher unit prices.

There is a certain logic to it, the sort that is often overlooked in UK government's (ahem) thinking.
Put simply: Not only are the bill-payers directly "subsidising" pv installations, they are also picking up an increased tab because there are, in consequence, fewer people across which to spread the cost of distribution around the grid. Therefore, pv users bills disappear and grid users bills increase.

Happy to be corrected.

Buy up all the nearly new, now unwanted, PV panels from Spain, very cheap, and install them as a non subsidised non FIT system in the UK.
the cheap price of nearly new but second hand panels will make it viable?

@Dave - Yup again.

I need to compare the payback time of that (just on saved electricity) and compare it to the payback time of an MCS system, taking into account I will only get the lower non EPC rate if I go for it now.
If MCS payback time is >10 years then the non FIT system will win.

I am about to get quotes for Solar PV on Chateau Great Crested Newt (Salamander Cottage).
Here's a link to the plan
Dave, you appear to be saying that it will pay me to buy some second hand panels and, since we will be living here until we pop our clogs, have them put up by a sensible sparky, and don't claim the FIT. Shove the excess juice to water.

The choice is get an MCS system installed BEFORE 1st Jan 2016 when the rate either drops by 87% or possibly even ends altogether. The problem with that, is like me you don't have a house yet so you don't have an EPC. So if you go for an MCS system, you will only get the lower rate of 6.16p per KWh generated plus 4.85p per unit exported which is deemed to be half your generation. So put that all together and you will get 8.585p per KWh generated.
Now if we assume a 4KW system and assume (up here in the far north) an expected generation of 3100KWh per year that's an annual income of a paltry £266.13
I am still waiting for a price for a 4KW MCS system but to even be remotely viable, it will have to be no more than £1K more than the non MCS system on offer on ebay. I'm working that out on a 4 year pay back for the "MCS premium"
This also assumes you already have an electricity supply to the site with your own MPAN (I have that already)
If I can't get an MCS system installed by the end of the year (or it's too expensive) then I will go non FIT and there will be no hurry to do so until the house is ready for occupation, by which time i expect the £2500 price tag to have dropped further.
For me it's technically possible to install my system now as I am going for a ground mounted system anyway (due to shading of the house by trees) so that can be installed before the house is ready.
If you are planning a roof mount system, then you would have to temporarily ground mount them now to get the system running for the FIT before the end of the year, then relocate them onto the roof when it is ready.
If we end up non FIT, then I will have to be more particular about self usage as I (on a matter of principle) don't want to be exporting free electricity. That wil include some DIY battery storage. I'm on the lookout now for some NiFe batteries if anyone hears of any for sale.
