    Wind power follows a weibull distribution. Plugin the mean windspeed and adjust the skew to your local topology. Small turbines can be noisy, especially from the stay cabling. They are expensive and need maintenance. But you can make your own. Hugh Piggott Axial-flow PMG wind turbine May 2003.pdf

    What is needed is a PHEV with a 6 kW PTO and 30 kWh of usable storage. A thermal PTO may be useful as well. Better get my pencils out and use my 40 year old degree in automotive engineering to save the world.

    I hope you are not suggesting that Putin may be homosexual. He is the embodiment of a man's man, just like Freddy Mercury was.

    Not the same sand they are using as a thermal store. Nord Stream 1 has not been turned on. Doubt it will.

    That is good, can use both sides. Not by much, maybe 0.5% a year, and that is probably down to better manufacturing that chemistry. There is a theoretical limit to what basic silicon can deliver, think it is 29%. So not worth delaying installation. Is there a decent stream on the grounds?

    Looks like a good roof for PV. Which way does it face?
  7. SteamyTea
    How many MWhs did they buy, and how does it compare in price to all the extra PV generation. Small part of a big story.

    So what have we learnt. My low tech (pot of mud, home grown bamboo sticks, and some old bean seeds from the back of the useful draw, plant, water and forget. Or your high tech methods?
  9. SteamyTea
    Got a bean.

    In the summer.

    Have a look in eBay for steel poled family tents.
  12. SteamyTea
    I do the driest of dry joints.

    Quit cheap. My old lightweight tent cost more than that 30 years ago. Don't weigh much, about 1.2 kg, and is still good. The replacement I want is not much more. Mates tent cost him 90 quid if I remember right.

    Mate of mine lived in one of these for 2 years when he was a student. Was pretty sturdy. https://www.anchorsupplies.com/ex-british-army-10-man-arctic-bell-tent-heavy-duty-unissued.html

    The voltage is closely controlled. So cuts out if it is over generating in the local grid. The voltage can be tinkered with to make it go higher, so not cut out. Very common fiddle to keep supplying power, and therefore FiT payments. Trouble is, if too many people do it locally, the voltages goes way over the maximum of 230 +10%, so 253 V. Same can be done to the lower voltage which is -6%, 216 V.

    Can try a magnet to locate any steel nails. Or an angle grinder.

    Kind of thing that @Onoff with knock up from scrap in his shed. We had a frame tent in the workshop to do all the dusty work in.

    Seem to remember our @Ed Davies having some quirks with RTCs, probably on his website.
  19. SteamyTea
    Yes it did seem an odd method. SMA sold inverters that were rebranded, can't remember the name now, they were totally unlocked, and cheaper.

    And people still want home automation

    I have some older RTCs, DS1307s I think. Would they be better supported?
  22. SteamyTea
    Did the installer disable it then. Had an electrician not set up the country code on a number of installs. Took weeks to get a code of SMA. Now spinning of the wheel would change it.
  23. SteamyTea
    Not used the SMA estimator/chooser for a decade, but it used to tell you how unbalanced the two strings could be and still work with their inverters. I always liked SMAs kit as an installer, customers could not fiddle with it.

    Not if the CoP of the ASHP suffers and frosting up takes place because it is trying to run at an elevated temperature.

    Make her pay the bills.
