    Apparently, if you have solar panels in Spain you a) have to grid connect them within 2 months of installation and b) pay €0.06/kWh for the electricity you generate. The only exemption is if you're far enough away from the grid for it not to be practical.

    http://www.reuters.com/article/2013/08/14/spain-energy-idUSL6N0GE1WR20130814

    I really really hope that a) this report is wrong and b) no government ever tries anything so mindbogglingly stupid in a proper country.

    No. The plan is apparently to charge for generation and pay nothing for energy that is exported to the grid...

    Thanks Skyewright. Had seen that thread but thought the Reuters report was a bit more definitive and coherent and also it goes further in saying that you normally can't just be totally off-grid or have an off-grid part of your house. However, something StephenDV says is worth comment:

    What's worse, is that some people have been installing semi-off-grid systems where it's essentially an off-grid battery based system but with a backup connection to the grid instead of a generator. It appears that these types of installs also fall under the same mandate, so they will have to install a consumption meter and pay the energy mafia for what they use in their own semi-off-grid setups.
    While this is indeed daft it seems to me that it would not be unreasonable to insist that people with their own generation but who use some grid supply be on a tariff with a higher standing charge to cover the cost of the connection and the more-peaky usage.

    That's only the half of it.

    Back in the old days, when FITS were introduced, many small agricultural groups formed co-ops, inviting parents, family etc, to purchase a small parcel of land, a couple of hectares or so, to erect 50 kW systems.

    Banks offered generous loan based on a business plan to pay of the debt within the first twelve years and reap an income/pension support for the nominal remainder of 12 or 13 years before anticipated lifetime failure of the panels. Of course, everyone hoped that they would continue to generate beyond that but that was the business case, and a sound one at that.......before the government reneged on the deal.

    Now the co-ops, and they are dozens of them in Andalusia alone, have little or no income in addition to having to pay the 7% levy on their generated product. Who said the sun was free? The result, where co-ops can't make the payment, is foreclosure, the banks then auction out the panels to any bidder and of course, the only people with any interest are the utilities. The infrastructure is in place and they can flog the juice at their wholesale rate.
  1.  
    As PV man in Italy I get a payment for the size of the system for 20 years that almost pays for the 15 year loan I took out to install my 28 panels and I get first call on my generated lecky, and I get paid about 17 cents/kW for exported lecky. Hardly a week goes by without wondering when the Italian bureaucracy will SNAFU us - I think they have already done something unpleasant to all non-roof mounted systems, which given all the PV fields that have sprung up around here owned by international (mainly Japanese) companies is understandable - sadly they didn't differentiate those v small (relatively) systems put on the ground by house owners with no useful roof!

    Fingers crossed! but also we took this on knowing there was a worst case outcome and we can hack it if it comes to it - you have do really consider all the risks on this sort of thing.

    BTW I think our panels had guaranteed 80% output after 25 years or something like that. Do we have any reliable info on panel longevity? And on Inverter longevity? Should I be saving a little every month to pay for these capital items when they die?

    Interesting idea.
    I didn't think the cyclists/petrol station analogy in the reuters article worked very well. An analogy of charging cyclists a (punitive) Road Tax might have worked better? Still not a perfect analogy (few are), but a bit closer?

    This is beyond the worst case I would previously have been able to think of (which would have been ending the FIT scheme and, just conceivably, banning export or even insisting on disconnection.) Despite the previous American insistence that you don't own the rain that lands on your own roof (now gone) I'd have never have thought of charging people for using their own equipment to make use of the sunlight falling on it.

    (P.S., perhaps next year they'll be charging people for sunlight coming in through their windows.)

    “Africa begins at the Pyrenees” is a somewhat cynical French saying. I previously thought it was rapidly becoming outdated (not withstanding their financial problems) but stuff like this makes me not so sure. And, yes, it's unfair to a few reasonably-well-governed African countries, too.

    Yes kWh
    Yes charging for the PV generated is worse than worse case.

    If the charge is less than the price of grid connected electricity then it could be worse.
    Say we started charging 10p/kWh for home generated and we buy it in at 16p/kWh, we are still better off (if you disregard the capital costs).
    Different if we charged 20p/kWh when grid was 16p/kWh.

    The PV industry has always banged on about price parity with the grid, what they wanted before the FITs was introduced, but if you think about it, grid electricity is sold to consumers at retail price, parity would have to be at wholesale price to make it worth while for the big power companies to buy it.
    Where subsidies/grants/incentives/obligations cause problems.
    Just tax the polluters at source, even at 100% of wholesale price it would only make less than 30% difference on the retail price.

    From a practical point of view, if you have problems with excess debt and electricity supplies then reneging on agreements with previous investors in electricity infrastructure seems insane.

    It sounds more communist revolution than 'right wing'.

    Basically yes, the market will charge what the consumer can pay. This puts upper and lower limits on what can be charged (it can be dressed up anyway you like).
    I think I read that the average domestic energy spend was about 8% of the average household wage.
    This could go up to possibly 12% (would not particular affect the top 50% of earners but would hurt the bottom 20%) for the same amount of energy used.
    But if this decreased overall usage by say 15%, the wholesale price would probably drop (this assumes that the European market does the same).

    It is really just supply and demand with volume and wholesale price on one side and percentage of household spend on the other.
    If this made larger 'profits' for the energy companies they would be forced to bail out the hardest hit (as they are now but few claim it).

    how's this for an "analogy" i once had an orange mobile phone that used your wifi to boost signal, BUT also took any resultant downloads (over wifi) out of you data allowance, so effectively charging you for using your own wifi. i think it was called "orange unique". needless to say that phone got rooted+flashed double quick!

    That would, indeed, be ridiculous and unfair (which doesn't mean it couldn't happen, of course).

    However, “you have fitted insulation, PV and electric heating to your house resulting in your consumption from the grid being much more variable than most so you need to pay a higher standing charge to cover the cost of providing it” would be disappointing but not so ridiculous and unfair.

    O a more serious note, would it not have been easier if we had just been forced to fit an import/export meter when fitting solar panels. The relevant government departments would have had real data to work with when setting prices and we would have got away from the two payments rates.
    Going to be interesting to see what fiddles happen with the RHI and any metering.

    I suggested that people don't buy the panels but got batteries instead, charge them up with off peak electricity and feed it back though the generation meter during the day.
    On a 4 kWp system you could swap panels for about £9000 of batteries, or about 50 kWh of round trip storage.
    Cost £2.5 to charge up but get back £22 via the FITs. That would be grossing £7000/year.

    There is a more serious point to this and that is what would energy storage actually be worth.

    Wear & tear on the battery bank (Depth of Discharge, cycles, etc.,) would likely be significant considerations.

    You might find this recent Navitron topic "why not PV as a 24 hour base supply ?" in which someone proposes the idea of large(ish) PV installs using battery storage to even out their input into the grid interesting? Battery costs & the matter of "cycles"/battery life are mentioned.

    Could tax some people sunbathing on public beaches, maybe a free allowance based on BMI, say anything below 20 is free, then 21 to 25 at 10p/hour, 26 to 30, 50p/hour anything over that £1/hour. Or should it be more expensive than a sunbed at about £20/hour :cool:

    The new Spanish legislation could be a nice little earner for the suppliers[Edit: i.e. the grid operators]? Maybe that will be relevant to the level of enforcement/compliance?
