    Complaints about solar panels have soared from fewer than 30 three years ago, to nearly 1,130 in 2012

    This is a red flag straight away. Is it surprising that complaints have soared when the number of panels installed has also soared? What are the actual number of complaints as a proportion of panels installed compared to 30 years ago? Author doesn't say.

    Don't think that REA was involved 30 years ago, and not every supplier was REA'd before the FITs, so hard to tell the true numbers as a fraction of installs.
    The financial side is interesting, 2 years ago some installers were claiming 5 to 6 year payback, seems that on average that is not happening. Though I have always questioned the payback anyway.
    Also the bit about devaluing property, though has there ever been a product that genuinely enhances the value of a house. Maybe gas heating :bigsmile:

    This is just another element of a new offensive by the vested interests in the fossil fuel economy. Just recently I have noticed a new flush of the propaganda seeking to undermine renewable energy and climate change science. The Sunday Times is not a trustworthy source but typically of many newspapers it is widely read by relatively intelligent people who can't be bothered to educate themselves about the real science.
    The fossil fuel, chemical and extractive industries are immensely wealthy and have almost limitless resources and political influence. They can afford to employ the world's smartest people and sadly these people are happy to pedal the lies. Power and profit is a religion. Examine Obama's recent statement about exploiting the Arctic as the ice recedes. It's covered in the Guardian. Exposes the naked greed of the US.
    The trick with the FiT rate being less than the price of kWh is a gift to the sceptics and I am sure it was entirely deliberate on behalf of the government. If we were to look at the family and business connections of the cabinet I'm sure the influences would be obvious. But as a piece of negative publicity the FiT rate is a killer. Why spend thousands for no gain? Just has to work if you don't think too hard about it.

    No.1 is as shevek says.
    No.2 complaints "could climb even higher given the sharp drop in payments paid to households", as if extg FITs customers were seeing their payments cut
    The rest - not a subscriber so can't read, but why should I?

    There was a similar spread in the Daily Mail last week. It was discussing ST in one breath and then PV in another. Do be honest I do not think the author had a clue that the systems are totally different. Worth looking up if you fancy a laugh.

    Having got a BSc in Renewable Energy/Environmental Science I am only too aware of the technical limitations of the two major ones, wind and solar.

    Was it ever really right to pay people to generate electricity at home knowing that they could, if they wished, use all of it for themselves, this is akin to buying 'a government sanctioned car', getting your tank filled for free and then demanding that everyone else in the station gives you cash as well.
    The real problem was creating a business model that relied on subsidies to each individual that signed up to the scheme. When I was working for a dodgy PV installer existing customers used to call saying that they felt aggrieved that they paid almost twice as much for their systems than later ones and felt entitled to 'better service' when things went wrong, the higher FIT payment was not mentioned.
    It really comes down to how individuals spend their money and if they think they are getting value from it, and value is very subjective.
    I do think this article highlighted that it was never a good idea, maybe it should have come out earlier.
    I wonder if 5 years ago I had said that you can have a system that will generate 4 MWh/year for £6000 or you can have an identical system for £8000 and I will give you back £600 a year for the next 20 years.
    Pre FITs showed the real costs of systems more than reduced FITs.
    A similar article about the pitfalls of the GD is due I think.
  2.  
    REAL (now RECC) came in with MCS when FITs started in 2010. This time three years ago FITs had been live for less than two months, so to compare the number of complaints now and then is totally disingenuous. Given the number of installations in the interim I'm surprised that the number of complaints isn't higher.

    The cumulative number of domestic installs are:
    May 2010: 1,313
    March 2013: 366,468
    Full stats here: http://bit.ly/16DcVxJ

    While solar panels don't tend to add value to a property in the UK (although research shows they do in California) research last year indicates that they are top 'deal-sealer' - ie if people are choosing between two similar properties, they are likely to choose the one with solar panels (http://bit.ly/19TVpBs).

    The picture caption shows someone who is having problems securing a new mortgage. This is likely to be because of a 'rent a roof' installation - where if you don't get a lease that meets the Council of Mortgage Lenders requirements you may have difficulties (http://bit.ly/18bru8Q). So, it looks as though they've googled all the negative things they can find about solar and lumped them together.

    Probably right and you very rarely hear from satisfied customers.
    Does not change the fact that there have been a lot of bad installs, a lot of companies going bust, people loose what they have paid for the system, unlike cash savings.
    Maybe it is worth writing a response to it for next weeks letter page. I am sure that someone can find a system somewhere that over produces, cost less and has never gone wrong.

    I think the mortgage issue is more to do with the survey than the devalue.
    Has REA/RECC published figures on how much and how many systems they have paid out on?

    "Probably right and you very rarely hear from satisfied customers." All my PV jobs have been through referrals (as with most my work) generally that's how customers show their happy with your work , and by paying you of course :)

    I agree though there've been some right dodgy installs and practices going on in the previous gold rush , most of which REA etc. have very little ability to do anything about.
    but if it's only 1,500 odd complaint for 300,000 installs , then potentially better than most other commercial activitites

    It wouldn't fit the Times' mindset but there is scope for a proper mainstream article about the state of PV.
    The number of times I hear 'I'd have loved solar PV but I've missed the boat'... Each drop in tariff makes the headlines and the subsequent drop in prices is rarely reported.

    The main change seems to be that you really need to fill a good sized roof to get a decent payback so it seems irritating that examples normally quote the figures for a ~2.5kWp system.

    Another often repeated misnomer is that you need a south facing roof when anything between east and west is almost as good (providing you can get lots up there).
  3.  
    Solar PV is now cheaper than it's ever been, half the price it was 2-3 years ago <£1500 kWp and therefore accessible to a larger section of the population should it take their fancy .
    Solar PV purpose is to generate electricity , not to make people money. even so it's still gives return higher than savings accounts etc.
    There is lots of potential for building that are in the position to use the PV generated energy as and when it's generated at a cost that's cheaper than grid electric if the long view is taken . Schools , hospitals etc. rarely change location so are perfectly placed to
    invest in cheaper (cleaner) energy such as PV.

    That couldn't be *this* cabinet, and I think you may be being a little too cynical. I don't think they aimed to wreck it, even then.

    FITs came in in early 2010, so that makes it a decision by Energy Minister Ed Milliband:

    Feed-in tariffs in the United Kingdom were first announced in October 2008 by the UK Secretary of State for Energy and Climate Change, Ed Miliband, who announced that Britain would implement a scheme by 2010, in addition to its current renewable energy quota scheme (ROCS). In July 2009, he presented details of the scheme, which began in early April 2010.

    The argument for reducing the FIT was that the panels are getting cheaper, so anyone installing PV would still be quids in. In principle that makes sense - anyone got any figures to show whether or not it is true?

    The problem was that the government reduced the FIT too sharply in one go, so the industry had a rush of jobs to beat the deadline (and may have cut a few quality corners), followed by a dearth of work. The next cut in the FIT, at the beginning of July, is very slight and unlikely to put off many customers, though I hear there is a bit of deadline-chasing going on.

    My in-laws paid £14k for a 4kw array and just beat the deadline for initial FIT reduction. They used a local installer who was great and were lucky to have a 45degree south facing roof slope. They were advised a likely 10-12yr payback which they were happy with. Their installation and subsequent performance has delighted them (£1880 return in year 1 IIRRC) so there are some happy customers out there but I think it depends entirely on the installer chosen and the sales patter received

    Not being directly involved on a day to day basis I was amazed when i sought a quote for our current build which came in around £5.5k for the same size system. Is this simply that the technology has matured and production costs reduced or are the install costs effectively linked to whatever FIT rate is current. I understand that there is further tarriff reduction in July so should I be waiting for a likely install cost reduction to follow immediately thereafter?

    Ed Davis did some back of a fag package calculation comparing the price of PV modules to double glazing. Think he decided that they were about as low as they could get at 50p/Wp.

    I agree Damon, it is a one way street, but it was an ill thought out scheme, as are all subsidies.

    Dunno, but I think a bit of both. Retail prices of panels alone have definitely dropped. I imagine there's been some improvement in the manufacturing but i think the main cause is simply the glut on the market caused by cuts in the FIT rates throughout Europe and particularly in Germany. At the same time, installers must be a lot more squeezed on installation costs with the less-than-completely-frenetic PV market.

    Overall, I think this behaviour of ramping the FITs rate up then pulling the rug out from under the market on the part of the governments is completely reprehensible. To then turn round to the Chinese manufacturers who are now basically trying to be the last ones standing as the market contracts and accuse them of dumping just adds both insult and injury to injury. OTOH, as Steamy would probably say, maybe they (the various PV manufacturers) were mugs to think western governments would take other than a very short-sighted view on the matter.

    Another fag-packet calculation: ignoring MCS and FITs you could probably do a DIY install for around £1000/kW (¹), particularly on a new build where you can reclaim the VAT and you have roof access sorted, electricians in, etc, anyway. That kW would likely produce about 800 kWh/year. If, as is not usually the case, you could make good use of all of that and your electricity costs £0.12/kWh that would save you £96/year giving break-even in 10.5 years with no dependence on the whims of future governments.

    ¹ Say £0.55/W for the panels, £0.35/W for the inverter and £0.10/W for mounting rails, cables, isolators, RCDs, etc.

    Yes there were a bit, but at least Germany and the UK do not want a trade war with China over this, not that we may get a say in it.
    This is an NREl report on global prices.

    At almost 10% ROI the government should be stopping fits as they are meant to keep it at about 8% under some EU rule or other. If that is the case then the installers should be increasing prices to protect their business.

    I fear that the supply cost of a 4kW array was never more than about £7.5k so there probably is a pretty close correlation bewteen the FIT value and commercial cost of supply and installation of small systems. The present FIT of less than 10p/kWh is still sufficient to allow industrial installations such as the 16,000 panels going into a farm near us.

    Never mind the sun setting on the solar regime, the wind is dropping on wind power. The campaign by the Telegraph papers hsa reached a zenith today with a headline stating that wind power has failed as it is costing £100k per person to subsidise the wind jobs. There is no mention anywhere in the front page article that this industry produces electricity, will reduce our reliance on fossil fuels and allow future generations to use gas and oil in small mobile engines rather than large static generation plants. Even thought about writing to the paper but not worth the effort so this morning is the last time I will but a Sunday Telegraph.

    Just has a thought to save us all money.
    The REF can pay me half this subsidy for the next five year to not work in the wind industry, that will save the tax payer £8.33... x 10^-3, that is less than 0.1p each year per taxpayer (assuming 30m taxpayers)

    Never have been convinced that wind farms create many jobs - the things are made overseas and put up by a handful of Contractors. A few local drivers might be employed in the ground works stage I suppose. The wind farm near me (W Wales) is controlled remotely by chaps in Shrewsbury and is owned by a Swedish firm. No local jobs from that then. So the job argument is always going to favour the antis.
