I said I'd come back for the month end figures.
July has been a dreadful month: 91% PVGIS - that's like missing 3 days entirely; 469kWh or 105.8 O's.
Compare that with April: 102% PVGIS, 480kWh, 108.2 O's
And to cap it all yesterday was the worst since 28 March.1 -
Poor day to end a poor month: 1.77 O'sJuly ended at 85% of PVGIS estimate and 80% of July last year.On the positive side, at least we haven't had heatwaves, droughts and wild fires.6.4kWp (16 * 400Wp REC Alpha) facing ESE + 5kW Huawei inverter + 10kWh Huawei battery. Buckinghamshire.2

July results.
Bad month with 93% of target. Big spread, with 88% for the ESE and 102% for the WNW.
Generated 575kWh (103.12 O's).
Imported 179kWh.
Exported 329kWh.
Total consumption 425kWh.
Gas was ~88kWh. [DHW & oven.]
Consumption still down to a more reasonable level (including BEV charging). But the very patchy weather, and rolling clouds, meant a lot of BEV charging was done overnight. A2A units not needed during the month.
Just a small(ish) batt of 4-5kWh, probably would have reduced import to zero(ish), but batts still some time away as the market is so messy.
Worst July generation, since install.
Year end projection of ~6,500kWh of leccy consumption, including BEV's and some space heating from A2A units. Gas projection ~6,000kWh.
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.
