yes Ken, I was lazy and did a cut and paste from November and forgot to update the kWh/kWpk figure - now corrected - Thanks for spotting it.

Our 3.2 array pointed SSE in the London suburbs generated 80.26 KWHs in December. For the year as a whole, I fear we consumed 9 KWHs more than we generated but that is the closest we have got to meeting our own demand, clearly largely due to the excellent sunnier - good old Greenhouse Effect!

With the Tesla battery, we reached a self sufficiency rate for the year of 73% and that was 4% better than the previous year. -

20kWh from 4.75kW of PV and 523kWh from a 3.2kW wind turbine, PV aint worth a feck at this latitude in December 


Now what would that latitude be then?
All records would be of added interest if we knew where the actual sites where.
