    Usual gripe about weather forecasters: Both yesterday & today all 3 forecasts assured me in advance that I wouldn't see sun all day. Both days had lots of brief sunny intervals - some peaking at just over 3kW. And (surprise, surprise) when I refreshed forecasts during day they all suddenly realised that previous period would have had sunny intervals although rest of day still wouldn't (and they were still wrong).

    Quite pleasing to read that tomorrow (i.e. Thurs) will be another sun-free day so perhaps I'll get another 10kW ?

    %ge of pvgis forecast continues to climb. Month to date *31/27 now suggesting 70%. Four more days >10kWh would take me up to 85%


    Apart from a slightly better result (9.9 kWh) I could make nearly all the same remarks again :rotfl:Peak generation was only just over 2kW but the total of cloudy intewrvals was somewhat less.

    Forecasters (again !) seem to be saying very little sun tomorrow but no doubt if it turns out bright again they'll try & convince themselves it's what they meant all along :D

    Forecast here has been a little better lately, with weather close to the 1 day (even 2 day) forecasts.

    Last 3 days of March are currently forecast as stunning. Generating 90W at 6.15am this morning, and now pumping out 464W. Nice.

    Predicted total is teetering on 80%, but a few over average days could pop it over my 82% lowest record.

    (I wonder if Oscar will get the #3000 post? :D)

    Early this morning, forecasts were still all agreeing that it would be a very cloudy day but perhaps with a few sunny intervals early on.

    "Bang goes my 10+ kWh" I thought. But I should of course been thinking "bang goes another chance for an accurate forecast". We'd actually generated 10kWh before lunch and although skies clouded over a bit more we still got to 14.02 kWh by dusk.

    Tomorrow's forecasts are looking remarkably like today's were at this time yesterday. Let's hope our forecasters have their usual degree of accuracy !:D

    2.25 O's today. We had few short periods. At one stage for few minutes the system generated at full power of 3kwh.

    2.32 O's for me...Best bet is to give a low kWh reading for the end of March; then let it catch up for the reading on your FiT payment date. I am lucky; my next reading date is May...:beer:

    Having said that; some people on here like the 'High Numbers' even though meeningless. Sorry Eric....smiley-shocked035.gif
