    Renewables: "talking 'bout my generation"

    Renewables: "talking 'bout my generation" 16th Mar 12 at 12:06 AM
    Please forgive the corny thread title inspired by The Who, but this post on the bloated 'how do I make the most of it' thread prompted me to initiate a new one...
    Hi Everyone,
    I haven't been here for a while, and am interested to see discussion of how much is being generated, rather than what to do with it.

    Well, there was yet another misty and bleak start in North Notts today (Thursday), but my SSW 3.92 kWp system was generating around 3kW for just a few minutes between 12.15 and 13.00, but enough to get the immersion heater hot enough for a shower. It seems to drop below that figure before it reaches 13.55 (optimum orientation). Final figure was just over 14kWh.

    BTW, there was an item about solar generation in Germany on the radio today; you can stream it here:
    http://www.bbc.co.uk/iplayer/episode/b01d2rvn/PM_15_03_2012/
    Just click on the speaker symbol on the left, then drag the time cursor at the bottom to 25mins 30 secs then release.

    My brother has the owl intuition PV monitor but they are now charging a subscription.
    Are there any other monitors, perhaps even better, that have no subs?

    I was going to buy an owl, but negative comments about the subscription stopped me.

    Otherwise there is Efergy or Smappe. If you want to go all out then there is the open energy monitor emonpi.

    Sadly a lot of the energy monitor companies have gone bust.

    Sadly my gen meter is in the loft, which is why I monitor my generation via a computer up there with an RS232 connection directly to the inverter. I've proven its accuracy by a few daily readings, and upload that to PVOutput. So this means I only read the gen meter to supply EON with fit readings

    The other 2 I view as more of a tool to see how much power I am using compared to generation so I can maximise the use of my generated energy (a bit like your Wattson).

    Seems to work very accurately, I had a new ABB Inverter fitted early last year, that is more accurate than the old 'Power One' that was installed previously...
