Post by AE-NMidlands »

Now the sun has gone down I have the final figure from my W-facing system: 580 kWh, 115% of the prediction and almost 128 kWh per kWp. What a month!
In fact this year has averaged 109.5% of the predicted amounts compared with 90.4% for all 2024. This year the lowest month (Feb) was 99%, last year the highest (June) was 99%...
2.0 kW/4.62 MWh pa in Ripples, 4.5 kWp W-facing pv, 9.5 kWh Givenergy batt
30 solar thermal tubes, 2MWh pa in Stockport, plus Congleton and Kinlochbervie Hydros,
Most travel by bike, walking or bus/train. Veg, fruit - and Bees!

Last May was my highest ever monthly generation at 1637 kWh, then it was broken in June last year at 2059 kWh.

(nowtyrecord)
This month is now a new monthly generation PB at 2339 kWh.

My energy bill from Octopus this month is a negative bill of over £290 :twisted: with over 2700 kWh exported, only issue is they have billed me for my import but not yet paid me for export. :evil:
19.6kW PV > 116MWh generated
Ripple 6.6kW Wind + 4.5kW PV > 34MWh generated
7 Other RE Coop's
105kWh EV storage
90kWh Home battery storage
40kWh Thermal storage
GSHP + A2A HP's
Rain water use > 530 m3

Work array generated 1.54MWh in May, a record, which follows record generation in April, March and Feb. Ok I know this is only year 3 of the system, but still!

Flippin eck. So you're exporting about 90kWh per day. You must be 'greening' the whole neighbourhood. :praise:

Synsynk shuts down automatically when my batteries are full, hence low outputs in good weather. I really really need to sort out an export contract given i have 4.0kw export ability.
