0.22kWh today:(
Panels covered in snow!
I could have cleared them but, don't think it would have made any difference.
Last year (Mar ?) although the sun was out, I was producing nothing, due to snow covering my panels.
Made a "panel clearer" from a lengh of plastic tube and a piece of rag,
gave 'em a wipe, and the rate shot up to 1.2kWh:D

Just in case anyone was interested (perhaps Eric). Today's weather which I'd been watching approach purely out of curiosity finally arrived. So which days forecast was right, the full sun, the snow, the sun and cloud, grey cloud, black cloud with rain, or none of the above. Well .... the results are in .... which did we get .....
Yes (all of them). I guess that's why the forecasts are so tough to get right, because we can have it all in one day. Plus some light fog as a bonus.
Still got 2.1, so not a bad day. Routine seems to still be zero or 1 followed by a double day. I guess it all balances out in the end.

Mart.
I've never disputed that there can be several different sorts of weather on the same day - and I guess that gives forecasters a better chance of saying "we were partly right".
However, most forecasts tend to say something like "cloudy at first, then brightening but rain later" and likely as not it will rain first then have a cloudy spell followed by a bright interval and it's really scraping the barrel to call that any sort of 'success'.
Nothing to report here for yesterday I'm afraid. We were threatened with several spell of 'heavy snow' - none of which happened ! We actually got just a little light snow but alas that was just enough to mask panels and our shallow pitch allowed it to lie there giving a total daily output of 3Wh.
Today a little better but the bright sunshine we've had for the last couple of hours gave a peak output of 100W rather than the 1.5kW similar days last week produced.
Fingers crossed for some heavy rain soon !NE Derbyshire.4kWp S Facing 17.5deg slope (dormer roof).24kWh of Pylontech batteries with Lux controller BEV : Hyundai Ioniq50 -
10.4kWh today, best day since November 18th :beer:
We're heading in the right direction and with 15 days gone we're now on target for the Jan PVGIS Classic estimate with a daily average of 3.8kWh versus 3.48kWh estimated. Still not quite as good as last Jan which was 14% better than this month has been so far.Cider Country Solar PV generator: 3.7kWp Enfinity system on unshaded SE (-36deg azimuth) & 45deg roof0 -

Some interesting results today.
This morning I removed all the snow from the System 2 panels on the garage roof.
System 1, on the house roof, is out of reach so it was left alone. There are two rows of eight panels in system 1. By midday the snow on system 1 had slid down to uncover the top row of eight panels. The sixteen panels are split into two strings of eight. The top eight are in one string, the lower eight in the other. At midday the clouds mostly cleared and the sun appeared. This means that one string was fully shaded (by the snow) and the other was fully lit.
Whilst the sun was shining, the output from system 1 was 185W but at the same time the output from the fully snow cleared system 2 was 1.5kW.
This shows what effect the shading was having. One might have expected the output to be half that of system 2 as half the panels were exposed to the sun, but the parallel string 'shorted out' the top row of panels.
As the snow slowly slid down lower on the remaining 8 panels the power increased to 675W. Soon after the clouds reappeared so there was no great kWh output for the day on either system.
