4.27 O's today so a gnats over par and for the first time this year we're actually ahead of monthly pvgis!Mar '21Solar generation = 706 kWhSolar consumed = 361 kWh = 51.13%Imported = 508 kWhTotal consumed = 869 kWh. ASHP's = 308 kWh's or 1232 kWh's if a COP of 4 is assumed so assumed total could have = 1793 kWh's. Zero Gas!Mar '20 = 463 kWh. ASHP's = 95.2 kWh's or 380.8 so assumed total = 748 kWh's.(Gas 22.4 kWh).Mar '19 = 588 kWh. ASHP's = 155 kWh's or 620 kWhs so assumed total = 1054 kWh's.(Gas 358.2 kWh)Mar '18 = 1944 kWh. ASHP's = 0. (Gas 1735 kWh's)Quite a year on year variation in consumption then, which I suspect is down to the weather, ie. outside temperatures, wind strength and direction rather than any change of fuel.East coast, lat 51.97. 8.26kw SSE, 23° pitch + 0.59kw WSW vertical. Nissan Leaf plus Zappi charger and 2 x ASHP's. Givenergy 8.2 & 9.5 kWh batts, 2 x 3 kW ac inverters. Indra V2H . CoCharger Host, Interest in Ripple Energy & Abundance.5

Not good today but, better than some 1.6 O's

Thanks CW, that tallies with my 'concerns', as gas consumption for Q1 was ~4MWh, roughly in line with previous years, and about 50% of annual consumption, despite much more use of the small ASHP's. I assumed this was down to the very cold temps we enjoyed earlier in the year.Coastalwatch said:4.27 O's today so a gnats over par and for the first time this year we're actually ahead of monthly pvgis!Mar '21Solar generation = 706 kWhSolar consumed = 361 kWh = 51.13%Imported = 508 kWhTotal consumed = 869 kWh.

Actually just checked back to an older cold Q1, pre ASHP's and that was ~6MWh. Phew!Mart. Cardiff. 8.72 kWp PV systems (2.12 SSW 4.6 ESE & 2.0 WNW). 20kWh battery storage. Two A2A units for cleaner heating. Two BEV's for cleaner driving.
For general PV advice please see the PV FAQ thread on the Green & Ethical Board.4 -
Just checked back to that quarter in 2018. Our consumption was 5.5 MWh. and for two weeks of that we away holidaying in the sunshine. Won't be doing that anymore, unless we decide on an adventure with the Leaf for a few weeks, or emissions free flyiing takes off.Might be a bit of a wait. I wonder which technology might be first with scheduled flights?East coast, lat 51.97. 8.26kw SSE, 23° pitch + 0.59kw WSW vertical. Nissan Leaf plus Zappi charger and 2 x ASHP's.
