    Just when you thought PV couldn't get any cheaper!

    Research Breakthrough Reduces Cost Of Solar Cell Production By 10%

    At this rate, in 5-10yrs time we'll be finding PV panels in the bottom of our cereal boxes. Anyone / everyone old enough to remember their collections?

    Only if the solar market in the EU is rigged else anyone can just start importing in September directly, the consumer doesn't care about company x who has inventory to shift at older higher prices. If anything the prices should come down within days of the announcement

    There's the term 'gold plating' and then there is actual 'gold plating' so I might not hold my breath for these PV panels for domestic use.

    “Golden Sandwich” Solar Cell Converts 85% Of Sunlight To Electricity

    Scientists at the Research Institute for Electronic Science at Hokkaido University have created what they call a “golden sandwich,” a photoelectrode that converts 85% of sunlight to electricity. Yes, this is experimental stuff and no, it has not yet reached commercial production. But stop and think for a minute what that could mean to the renewable energy revolution.

    The breakthrough from Hokkaido University hints at future solar cells that could be 5 times more efficient than current cells. Of course, we have no idea what commercial versions of the technology might cost, but just imagine getting 5 times as much zero emissions energy from every solar installation. The implications are staggering.

    So what’s the secret sauce for making a golden sandwich? A titanium dioxide film just 30 nanometers thick with a 100 nanometer thick gold film on one side and gold nano-particles on the other. When sunlight strikes the nano-particle side, the gold film below acts as a mirror trapping the light in the cavity between the two gold layers. That helps the nano-particles to absorb more of the available light, which is critical to the surprisingly high energy conversion factor.

    Oxford PV keep pushing the efficiency of perovskite PV higher and higher.

    Oxford PV aiming to ‘push the boundaries’ with new five-year perovskite research project

    Perovskite specialist Oxford PV has announced a five-year research project with the University of Oxford that it says will push the boundaries of perovskite technology.

    The £5 million research project intends to develop a thin-film, multi-junction perovskite cell with a target efficiency of 37% as well as long-term stability in operation.

    Such an efficiency would represent a major leap for perovskite cells. In June this year Oxford PV claimed a new world record for certified efficiency of a perovskite-on-silicon cell at 27.3%.

    Half of the fund has been granted from the Engineering and Physical Sciences Research Council as part of its Prosperity Partnerships programme, while the other half has been matched by Oxford PV.

    And Labour's plan to treble PV deployment by 2030, which I don't think should be a political point, it should just be bleeding obvious to any party in charge:

    Corbyn’s Labour government would treble UK solar capacity, create 400,000 green jobs

    Unsure if this has been published elsewhere but thought it worthy of posting just to re affirm, as suggested previously, that Solar without subsidy is viable if only on a large scale!


    SunGift Energy has installed a 140.5kW solar rooftop array on behalf of the University of Exeter, a project completed without the need for subsidy.
    The array comprises more than 500 panels and covers 800 square metres of the university’s sports hall roof. It’s expected to generate just shy of 125,000kWh of power each year, all of which will be used on-site.

    The weekend read: The MIP comes to an end

    Prices down

    Module prices could decline as much as 30% from current MIP levels. Prices in Europe will quickly drop in the coming weeks, as the MIP was artificially maintaining higher levels than the global average – the MIP price for multi modules was €0.30/W ($0.35) – 30-40% above average global prices.

    Due to this price gap, and the willingness to accept minimal margins following the slowdown of demand in China, termination of the MIP will cause module prices in Europe to decline for new contracts by as much as 30%. For project developers and EPCs, such a cut will immediately drive down total project costs and the corresponding LCOE, and raise project margins for already contracted projects.
    With PV modules representing about 50% of the cost of a PV farm, and about 30% of residential install costs, we might see a reduction of around 15% and 10% respectively .... might!

    Some interesting articles from this week's Carbon Commentary newsletter (back from a summer pause).


    8, Thin film solar. The world leader in organic photovoltaics, Heliatek of Germany, installed a 180 square metre array on the side of a warehouse in Duisburg. This is the largest thin film installation on a building façade in the world. Heliatek’s films are so light that they are literally stuck onto the side and roofs of buildings. My guess is that this installation has a conversion efficiency of less than 10%, or about half that of good quality silicon PV. But I also suspect that this is irrelevant; Heliatek’s films can be used almost any surface, including those where conventional PV would be impossible.

    10, Embodied emissions in solar PV. Every so often the rumour resurfaces that manufacturing solar panels creates more emissions than are saved when the PV is installed. The story will become more difficult to tell in the future. Longi, one of the largest PV companies, announced that all the electricity it uses to make panels will come from solar farms within three to five years. (Electricity is the dominant energy need in panel manufacture).

    First highlighted by Mart in July, Amazon are firming up their intentions to install Solar and Storage facilities on more of their UK sites!
    Retail giant Amazon is to install 20MW of rooftop solar across its UK fulfillment centres within the next 18 months alongside battery storage aimed at delivering local and national flexibility services.
    The company has now unveiled its plans in full, which will see systems installed on ten of its fulfilment centres, subject to planning and landlord approval. The projects, which will be developed and funded by Macquarie Principal Finance, form part of a commitment announced last year to deploy solar arrays on 50 customer fulfilment centres globally by 2020.

    Big potential for PV in Europe now that the MIP has ended. Some articles are suggesting module costs as low as €0.20/Wp (also taking into account that there might be some overproduction this year too). I think (mighty be wrong) that the MIP was around €0.40/Wp.

    End of MIP opening a ‘huge door’ for subsidy-free solar in Europe


    Grid parity promise makes European solar a ‘sleeping giant

    Dale Barnard, senior project engineer at Denmark-based developer, European Energy, also celebrated the effects of the MIP ending combined with China’s subsidy removals, citing an IHS Markit report on prices dropping 30% across the board, with panels in Europe bottoming out at €0.20/W.

    He described these as “insanely cheap prices” that could only have been dreamed of last year – adding: “It almost opens up the entire European market for subsidy-free, perhaps with exceptions for some of the very northernmost countries.”

    Niendorf cited several countries where post-subsidy projects are already proliferating or are set to kick-start merchant PV in the coming year, including Spain, Portugal, Italy, the UK and the Netherlands.

    Got to be honest, I'd have been shocked if the result had been anything different:

    Poll shows Brits support EU regulation to pay solar generators for export, including Leavers

    Didn't know about this:

    A majority of the respondents in a new YouGov poll would support the UK matching incoming European Union regulations that guarantee payments for solar homes exporting into the grid; including those that voted to leave in the Brexit referendum.

    Would it not be possible to fit an Export meter, rather than a Generation meter, for any new installation after March 2019? So that just Export is measured and paid for.

    Folk probably know about 'CIGS', light weight, cheap and low efficiency solar panels. Here's an article looking at the benefits and options available, such as flexible sheets of lightweight panels.

    My first thought was you buy a lightweight shed, then cover the roof and 3 sides with sheets of this?

    Just a comment, or out loud thought, but I was having a nose at some Ikea bits and bobs, and like a dog spotting a squirrel I got distracted by the solar install reference.

    Only a quick play but for a normal roof layout (not complicated, presumably for scaffolding costs) I priced up a 4.35kWp system (15 290Wp black panels) for about £5.5k.

    In no way wishing this to seem like an advert, but that seems reasonable to me, and certainly a starting point for referencing prices when we see some of the silly quotes people new to PV come on here seeking advice about.

    Again, just to clarify, not bigging up Ikea, but that gives us an approximate backstop reference when suggesting rough price targets - doesn't mean everyone should head to Ikea.

    Interesting article and package, showing subsidy free investment, Council's ability to look further ahead than some investors might be able to, and the various uses of the combined storage. Also the advantages that a council may have, such as owned land etc.

    UK’s second subsidy-free solar farm completed by West Sussex Council using battery storage

    The Westhampnett project combines 7.4MW of solar, comprised of panels from Hanwha Q Cells, with a 4.4MW/4.06MWh battery storage unit from Tesvolt on a closed 35 acre landfill site close to a local grid connection and owned by the council, offering low land costs for the project.

    Edit - Further (out loud) thoughts, but:

    owned land - tick box
    low value / unusable land - tick box
    close to a grid connection - tick box

    I wonder how many locations there are like this in the UK? I'm going to assume 100's, possibly 1,000's?

    Having already exceeded their 2020 PV target by ~50% (165GW v's 105GW), China might go even further:

    China May Increase Its 2020 Solar Target To 200 Gigawatts Or Higher

    China’s National Energy Administration has floated the idea that it might increase its 2020 solar target to at least 210 gigawatts (GW), and potentially as high as 270 GW, in a move which will significantly impact China’s annual capacity additions and, thus, global capacity additions and solar PV manufacturing.

    No details but a Govt Minister saying they are looking at some sort of payment for exported PV leccy when the FiT scheme ends:

    " ..... I completely agree with him that solar power should not be provided to the Grid for free, and that's why I will shortly be announcing the next steps for small scale renewables."

    Ooops! Not good news by the sound of it!
    Solar will face the “greatest potential impact” from new proposals by Ofgem to apply fixed residual charges to all final demand users and end the Embedded Benefits for smaller generators under its Targeted Charging Review (TCR).
