That's good going! :D Grey skies up here today with barometric dropping. Still generating 1.2 to 1.5kW which passes the Clockmanfra test of 1kW in poor conditions. I wonder if he sold his place in France?

Nice sunny weather down here, some clouds, but not bad.

Wednesday saw new records, 85.19 generated and 89.77 exported, we usually import around 29 kWh each day - I fully charge the batteries and run the house from the grid between 23:30 to 05:30.

PS. Vaillant app reports 3.4 for hot water this month.

Congratulations on the PB's and that is a great DHW cop. Has it all settled in now the ashp i mean, reads like it has? Sun has come out and we are generating a bit over 8kW now. Long may it continue across all the Shires! :D

The home is recharging via solar gain. That was a two day grey sky test and it managed it well. Heating has been off for quite a while now. SWMBO is back home today so a pleasant surprise for her.

I still need to tidy up/replace some of the external insulation, I've got it, just need to do it. Hot water wise its working perfectly, never run out, and at 55c its plenty hot enough, averaging 3.16 kWh a day to run the heat pump for hot water.

I've moved the outdoor sensor, it was on a ESE wall, I've now mounted it on a NNE wall, it does get rather warm in the early morning sun, but come winter that won't be a problem.
