    Solar ... In the news 7th Jan 13 at 5:36 PM
    Hi All

    Thought it was about time we had a thread specifically to discuss relevant press articles relating to solar pv & thermal ..... so here goes ...

    And only time will tell if they've used the comparatively expensive silicone gel to attach the cells to the glass, or a cheaper knockoff which goes yellow in 15 years.

    However, China has just connected its first domestic PV system and if their incetives work they could soak up all the extra production domestically.

    There is a theory in the industry that their government has had a plan to push production costs down by flooding the market to make their panels affordable domestically and also eliminating competition in the west. They have a proper plan there...

    Yep , I've noticed that. Looks right cheap, the outer frame/trim has no structural strength of it's own, unlike say Schuco or REC which seem the best of the bunch, where the frame appears to have some strength in itself without the lament glass panel.
    I was slightly surpirsed the panasonic(sanyo) panels also seem a little , lets say unrobust
    Glad to see sunpowers confident to offer a full 25 years on product most others offer 5-10. Used them once so far, didn't take note of the build quality at the time.

Plus, of course, we've exported a lot of our CO2 emissions to them, along with our industry!

    This Forbes report is interesting, possibly more so as it's a little out of date and asks a lot of questions about 2012.

    "China was responsible for almost one-fifth of total global investment, spending $52 billion on renewable energy last year [2011]."

    The way things are going in the british media you'd better watch out if you have panels visible on your roof as you'll soon have journalists on your doorstep throwing stones at them...

    Ed Miliband's solar swindle
    Originally posted by The Green Hornet
    I share your sentiments about Daily Mail articles, and indeed there are a number of inaccuracies, including apparently the 40% drop in output.

    For instance this quote wrongly gives the 'impression' that the subsidies are paid on the electricity returned to the Grid.

    Households with solar panels are paid for returning energy to the grid
    Much as I am loath to agree with Tory a MP, his conclusions are not really disputable.


    The solar subsidies inherited from Labour have been nothing short of a giant
    waste of time and money.

    Ed Miliband’s flagship green subsidies have proved a ludicrously expensive
    way of backing inefficient technology.
    Spreading this message on forums like MSE will hopefully get people to appreciate what a farce the FIT system has been.

    Here's the Telegraph's version:

    http://www.telegraph.co.uk/news/politics/9796444/Cost-of-Ed-Milibands-solar-panels-scheme-jumps-900-per-cent.html

    It's a good thing they didn't 'do the maths' after the very first install, or the headline would have been

    "Cost of Ed Miliband's solar panels scheme jumps 900 infinite per cent"

    Legoman, this article also mentions:

    "Separate, figures also show that their performance or "load factor" has fallen by 40 per cent over the three years to the end of 2011."

    I wish somebody had told me this. Maybe I should write to my MP?

    1. Forgot to mention this, Bloomberg TV ran a small feature on PV last week. Partly prompted by Warren Buffett's move into PV generation. Bloomberg consensus was that putting money into PV stocks at the moment was risky, especially as China plans to further increase output - so panel prices good, US manufacturing unsteady.

    2. Reading New Scientist last night (issue 2898 5/1/13) and they had a feature on energy storage and renewables. It focused mainly on air storage and a test plant that has been ticking away in Slough for some time. Very interesting article as efficiency potentials are around 70%, but costs much less than pumped storage (water), and can be sited locally to take advantage of waste heat. Also uses existing kit and engineering skills.

    Some positive comments:

    ""This could save the UK billions", says Tim Fox, head of energy and environment at the institution of Mechanical Engineers in London."

    and on storage in general:-

    " ..... New policies such as these should prompt a boom in energy storage. More than $100 billion is set to be invested in energy storage over the next decade and the race is on to capture that market. The winners will help solve the biggest environmental problem of our time."

    Found some 'bits':

    Some renewables news from Fukushima:

    i. Solar park on contamintaed land:

    http://www.newscientist.com/article/mg21528764.800-japan-could-become-second-biggest-solar-power-nation.html

    ii. World's largest off-shore wind farm:

    http://www.newscientist.com/article/dn23082-japan-to-build-worlds-largest-offshore-wind-farm.html

    These projects also take advantage of the powerful grid connection infrastructure left over from the nuclear industry.

    Japan is also to launch a FIT @ $0.5/kWh:

    http://www.japantimes.co.jp/text/nn20120630f1.html

    "The FIT system will immediately boost demand for solar panels, creating great opportunities for all solar battery manufacturers and related companies. It will lead to cities installing more solar panels, and the development of better energy management systems,"

    Just imagine what those clever Japanese will develop in the next decade!

    Since the Tsunami they've developed their electric car charge points to allow the car battery to feed the home in cases of grid failure.

    The EV's could be the first real step in home storage. The chaos after the disaster has changed their mindset and they are now really focussed on grid autonomy during these extreme events. The new housing estates all have PV and EV charge points as standard.

    Although it looks like there will be some nice new L-ion batteries going for scrap from the 787 fleet...

    Your link is broken and shouldn't the headline be

    "Solar companies to sue UK taxpayer for 140m over feed-in tariff cuts"

    as the Government has no money of it's own.

    Hi All

    Pretty typical of German 'joined-up-thinking' ..... http://criticalpoweronline.com/news/012013-181/ ....

    With solar pv in Germany being pretty close to a saturation-point where further installed capacity would likely cause major grid issues this looks to be a positive move towards a supply-to-demand solution ...

    Maybe this time it'll work.
    All prior efforts have pretty much died due to the decreasing price of crystalline solar.

    At the moment, I'm almost of the belief that cost per watt and efficiency are a somewhat of red herring, other than incidentally.

    What's needed is solar that is not panels.
    But that is an asthetically acceptable whole-roof-covering that has a lower lifetime TCO than a conventional roof.

    In principle, there isn't anything really hard about flywheel energy storage - it's just putting the money into getting the costs down, which nobodies done.
    The 'compress air to use in jet turbines and burn gas with for higher efficiency' is a neat wrinkle.
