    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 ...

    Solar panels for world’s first combined hydro & floating PV project installed in Portugal

    The project came about as the result of a pilot tender to add PV generation to the hydroelectric dam in Northern Portugal, in which Ciel & Terre was chosen as EPC provider. The solar panels are installed on a floating island, and will allow the plant to save hydropower to compete at peak demand times.
    If I'm understanding this correctly, they are saying the PV generation allows them to reduce hydro generation. The hydro generation can then be used at peak (selected) times instead.

    So this simple combination means the PV gen is being stored for later, without 'technically' requiring any pumping or additional storage, or any storage losses. I think?

    Perhaps a few wind turbines round the edge would help too.

    Saw this in a newsletter I get. I wonder how long it will take to make the system commercially viable.

    France promotes:

    France ramped up solar ambitions after PV ‘overshot expectations’

    France has sought to increase its ambitions for solar PV in the country after the technology “overshot expectations”, a government representative has said.
    Dutertre’s comments come just weeks after the European Commission approved French solar schemes to support the development of 2.6GW of small and large-scale plants as the country continues to make progress towards its target of 23% renewable generation by 2030.

    Britain taxes:

    Schools to be hit by almost £2 million annual bill from solar tax hike

    Schools in England and Wales could face an annual bill of almost £2 million if the government goes ahead with the planned introduction of business rates on small solar installations, according to the Green Party.

    Jenny Jones, the party’s member of the House of Lords, obtained information through Freedom of Information requests from 74 education authorities, responsible for 821 schools with almost 14MW of installed solar capacity.

    The Greens have argued that when scaled up to all 174 education authorities, the proposed removal of the exemption for non-domestic solar installations below 50kWp would result in a total business rates bill in the region of £1.8 million per year.

    Just copied this of a weekly carbon commentary newsletter:

    At a lecture in Oxford, leading perovskite scientist Henry Snaith said that his university spinout was talking to a major silicon manufacturer about adding a perovskite layer on top of PV cells to increase light-capturing efficiency. He said it would increase yields of the best PV cells from 22% to 30%. Professor Snaith also said that trials of perovskite cells were showing good durability in the face of humidity and high temperatures. This has been a major concern of observers. Separately, a US/French study showed impressive performance from extremely thin layers of perovskite materials, increasing the possibility that these cheap and light materials will one day become the lowest cost source of PV modules.
    To place this in context we could be seeing almost a doubling of the efficiency of rooftop PV in the short to medium term ...... doubling of annual generation from the same roofspace. Nice.

    For similar reasons I too would be interested in such a product. Just a tad worried that the operation might be classed as changing the panels and losing FIT entitlement though.

    IF something ever comes onto the DIY market I'll make a point of enquiring of my FIT providers before I rush out to buy it.

    Brain still whirring on this, so it might not make sense, but if you increased the efficiency, you would increase the Wp rating of the panel*, so ..... it would be an upgrade or extension, which would be apportioned off by the FiT provider ....... I think?

    *Eg a 240Wp panel 1m by 1.6m of 14% or an identical sized panel of 17.5% efficiency giving off 285Wp. So same space, higher efficiency, higher Wp too.

    Long term though (or should that be short-medium term) the thought of generating perhaps 6,000kWh-10,000kWh from a domestic roof in the UK each year is staggering. Gonna need a bigger battery!

    Ah but - the efficiency of the panel itself is not increasing? The same cells are doing exactly the same job they were doing before. But the light they are receiving allows them to perform better - or have I got this wrong?

    Oh, and any affordable (i.e. cost efficient) battery would be great right now no matter what the size.

    PV or not PV, that is the question. Whether it is nobler in the mind to suffer the slings and arrows of outrageous efficiency.

    Fun problem. Hmmm, if you are adding some sort of back face thin film PV, like the high efficiency panels, even if only theoretical, then I suppose that's a Wp increase.

    If you add some sort of external mirror or reflector to get more light onto the panels, then that's probably not a Wp increase.

    But if you added something to the panels that focused more light, or also generated leccy, then we may be in some sort of grey area.

    FiT wise, you'd generate more, and get paid more, so 'what the hell', but the FiT rates were based on expectations and technology at given times ..... head hurting ...... I don't know.

    I'd considered all those points and still not sure how I'd regard it - let alone how a FIT provider might

    I expect it will only be one of those ideas that get floated but never happen but if it does ever come to anything I'll start making enquiries.

    Scilly idea to help with fuel poverty.
    Moixa, Hitachi collaborate on GBP 10.8m Smart Islands EV, solar+storage project on Isles of Scilly

    The British archipelago of islands to become global testbed for Smart Islands project that aims to provide model for use of electric vehicles and home batteries in a smart energy system.

    The sunniest, remotest and most energy-poor region of the United Kingdom is poised to become a global testbed for measuring the efficacy of using electric vehicles – charged by solar panels – to play a leading role in managing a low-carbon smart energy system.

    The Isles of Scilly, an archipelago located 28 miles off the coast of southwest England, have been selected for a GBP 10.8 million ($13.2 million) project by the Hitachi Europe-led Smart Energy Islands (SEI) project, which will see up to 100 rooftop solar systems, two 50 kW solar gardens, around 290 home energy management systems and a handful of smart batteries installed across the islands.

    These systems will be controlled via integration with Hitachi’s Internet of Things (IoT) platform, which will act as a central point of control for an Electric Vehicle Management System and a Home Battery Management System.

    Transmission system demand on Saturday afternoon (25 March) dipped below overnight demand for the first time in the UK’s history, with increased solar generation the root cause.

    Between 1pm and 4pm demand on Great Britain’s transmission system dipped below 25GW owing to increased output from solar PV generators which benefitted from ideal weather conditions.

    This, according to National Grid, was below the overnight minimum demand of circa 26GW; the first time this has happened in the UK.

  • Who do you think came out best in the Corbyn v May battle tonight?

  • Clever by Paxman; subtly testing out "strong & stable" by focusing on u-turns on Brexit view, social care, self employed tax & election date

  • Ps sadly i got in too late to have seen Corbyn, hence why no comment on his performance
