Solar PV monitor

    My solar generation meter is very accessible so sometimes in the mornings I count the time between flashes to get an idea about whether there's sufficient generation to start a washing machine or dishwasher cycle or if I should wait. I have a puny 1kW solar array (installed by developer on newbuild house)

    4 seconds between flashes = 900W - enough to put a good dent in consumption of a hungry appliance.
    7 seconds between flashes = 514W
    10 seconds between flashes s = 360W - nothing to get exciting about but better than export.
    24 seconds between flashes = 150W - covers baseload and not much more.
    One LED on constantly = no generation.
