    Does anyone know of a service - similar to http://solargis.info/ - which provides 15 minutely historical data for a specific spot - or an area.
    The above site does provide exactly what I want - but I need to buy information from a 100km square, for 150 euro. And that's a bit steep when I want a point.
    Hi

    Why not pick a couple of representative systems from PVOutput which are sending their data in on a similar frequency and look at their data ?? ... much cheaper !

    Interesting article and a couple of extracts.

    China Might Be Winning The Race To Reduce Solar Costs
    Many people, even fanatical advocates of solar power, are unaware quite how close we are to reaching a critical milestone in the industry. Within a fairly short space of time, solar generated electricity will be fully cost competitive with coal-powered electricity -- at least if the governments of the world's two largest energy consuming nations have their way.
    The simple fact is that with both innovation and increased capacity, the cost of solar energy has fallen considerably over the last few years and continues to do so. If, as looks likely, it does become truly cost comparative with coal in the next few years, then the days of cheap, clean, renewable energy dominating the world's two biggest energy markets may be closer than you think.

    Storage is coming and it is getting cheaper and easier than ever before...

    http://www.navitron.org.uk/product_detail.php?proID=962&catID=178

    A 3.7kWh inverter, 100Ah of Li-ion batteries with room for expansion to 250Ah for £4k. Can also be used for some loads in the event of a power outage by the looks of the diagram.

    When the time comes to replace my current inverter, something with integrated battery storage is looking more and more likely.
