4kw FIT system yielded 378.0
5.45kw Sunsynk yielded 222.8

Old FIT system outpaced the Sunsynk as Sunsynk shuts down once batteries are filled and only pops on again if they drop or high load made on the system, expect the Sunsynk system to 'decline' in output as the sunshine improves and the FIT output increases.

Nowty, A friend, not yet on here, but likely soon has just commisioned a self installed 3.6kw Ecco Sunsynk invertor and 4kw of panels, 15kwh Fogstar battery ordered and awaiting delivery. All up and running and switched on last week, not sure if this can be added to the 'associate' list of producers - likely all power to be self consumed as quite a heavy user.

April results:
- Sunsynk system 453kWh - below 490kWh PVGIS - also rather down on last year at 527kWh
- Hoymiles Man cave (2 panel version) 63kWh

Solaredge 393kWh
Victron 337kWh
Enphase WS 28kWh
Enphase HT 6.2kWh
No1's Hoymiles 55kWh
Graig Fatha WT 689 kwh

1,508kWh RE generation minus 55kWh No1's Hoymiles = 1453kWh solo home gen.

659kWh electricity bought from grid for our place is 68.8% self generated RE in the monthly mix & Zero gas or liquid fuels.

Great to see home solar outstripping wind generation again.

No1's place on which we are waiting for an appointment to change to a smart meter has landed a 16.76% score for self reliance in the energy game from his two panel Hoymiles system. He is now on the Kirkhill scoreboard too. Albeit for one unpaid day.

April:

Solar: 680 kWh
Consumption: 577kWh

System efficiency: 85% < Efficiency has gone up now we have loads of excess DC coupled solar generation. We're also using excess solar for electric heating top up, hence the consumption is much more than otherwise normal. The Sun has really turned a corner here for us last month.


Last Month (March):

Solar: 394 kWh
Diesel Generator: 0 kWh!
Consumption: 309 kWh

System Efficiency: 394kWh - 309kWh = 78%

April 2024 - just pipped 2023's stats

11kWp Office Array.

Total generation - 1.101MWh (1.077MWh last year)
Self-consumption - 0.79MWh (72%)
Export - 0.31MWh (28%)

Overall electricity consumption 3.09MWh
Imported 2.29MWh (74%)

Not quite as good a month as last year, down 30kWh vs 2023.
Saying that, PV contribution was still 94% of house usage - the fan heater has been on a fair bit this month to soak up the excess PV whilst it was still cold.

Nowty Towers Power Station
Main 4kW PV system generated 386 kWh which is about 17% below baseline.
Total PV arrays generated 1203 kWh.

Electric Import was 598 kWh.
Gas import was 11 kWh.
Out of house EV charging was 0 kWh.
Petrol used in EV hybrid was 0 kWh.
Total imported energy use 609 kWh

Solar PV / Battery electric export was 978 kWh.
Ripple GF wind farm generated 1096 kWh which is about 55% above baseline.
Total energy offset 2074 kWh

Net energy import/export (this month) for Nowty Towers 1465 kWh

Net Energy Import/export (cumulative this year 2024) for Nowty Towers 804 kWh

My results for April were:

3.87 kWp, slope 50 degrees, due south, lat 57.15

Total generation: 356.7kWh

Daily average: 11.9kWh

Generation per kWp: 92.2kWh

Daily average per kWp: 3.0kWh

PVGIS: 349kWh

%PVGIS: 102%

Down 15% on average.
