3.1 O's for yesterday and 4.34 today. SE stopped reporting on 30th July and I await a visit from the installers due Tuesday. Some people have to have a holiday after all. Anyway, subsequently taken to visiting the garage each evening to obtain the last two figures. Today surpassed 33MWh's since installation.

I'm back from my week visiting relatives.The first bit of good news: my DIY 48V, 25Ah lithium iron phosphate battery didn't burn the house down in my absence
Oh yes, my solar stats. For 8 days (7th to 14th inclusive):78.28kWh, 28.78 O's. A daily average of 3.60 O's!
You'll find it varies; you'll use a much higher fraction in the winter, when you're not generating much, but only a small fraction in the summer. 30% is a good working estimate until you get some real numbers.Spies said:What's everyone's self use? I've calculated I would average abut 30% as I don't have an EV and no immersion heater either.N. Hampshire, he/him. Octopus Intelligent Go elec / Fuse gas / Vodafone BB / iD mobile.

Quick one as I don't think it's worth me making a thread about this...
As light gets low, does generation suddenly go from say 150w to zero because they drop under the startup voltage of the inverter? And vice versa as the sun's coming up?4.29kWp Solar system, 45/55 South/West split in cloudy rainy Cumbria.1 -
Sounds plausible to me, but guess the answer might be found in the Inverter gumpf somewhere!4.37 O's today, but the week ahead looks decidedly cloudy.East coast, lat 51.97. 8.26kWp SSE, 23° pitch + 0.59kWp WSW vertical.

Today was pretty dull and gloomy so I'm quite pleased with the generation numbers.8.11kWh, 2.98 O's.
Pretty much. In my case there's a period after dawn (and another, before dusk) where the inverter actually *draws* a few watts of power; it's light enough to wake the inverter up but not light enough for the panels to be productive. The manual says it should start feeding the grid at 15 watts but it seems to need a bit more than that in practice (but still less than 100 watts).Spies said:As light gets low, does generation suddenly go from say 150w to zero because they drop under the startup voltage of the inverter? And vice versa as the sun's coming up?My inverter is relatively old technology and they might have improved!N. Hampshire, he/him. Octopus Intelligent Go elec / Fuse gas / Vodafone BB / iD mobile.
