    That's why this thread is useful, reading rest of postings your output looks low @Ha Long Bay, shading perhaps?

    Update from me,

    8.6kwp NE/SW split, 8.4 SW, Up to 40kwh of battery storage now. rates are 27.8day, 7.9 night.

    image.png

    To note the battery discharge at night was a failure of automation.. Have updated a few things, hopefully wont happen again.

    could be passing 1200kwh in march. If its anything like last year.

    Stopped charging the battery at night about a week ago.

    500kwh on the nose for March, just 6% shy of PVGIS estimate so not too bad considering. 50kwh into Eddi, and hardly needed to charge the EV at night at all, and being able to phone manage the night-time battery charging based on next day's general forecast is v handy, so content with self-consumption level. aaand the oil boiler is mostly off now 🥳

    6.1 kWp System South of Cork City

    413 kWh

    Used 53% of it which I need to better on. This month is just 53% of March 2022 production which was 774 kWh, looking back at that month wow!

    Total Electricity consumption for March was 1,860 kWh, 37% that was the EV.

    My 7 day average is moving up to the high teens now, roll on the better weather

    My overall solar production for March was 392.6kWh.

    75.5 kWh diverted to Eddi

    221kWh Exported (current FIT price = 0.21/kWh = 46.41 Euro FIT value)

    Total Domestic Electricity Consumption (excluding Eddi) = 130.65kWh, solar contributed 35.1kWh and we imported 95.6kWh off the Grid (Post VAT electricity rate = 41cent x 95.6 = 39.19 Euro payable to Billing company)

    download (2).png

    There were a few good days at the end of the 1st week of March but momentum never really carried over into 2nd half of March. We lost several hours of production on the 15th March (also our worst day of production) when our smart meter had a fault resulting in a 14 hour electricity outage.

    Our best day was 10th March =29.2kWh

    5.6kWp - SW (220 degrees) - North Sligo

    225kwh from 3kwp sw 1kw ne and as others have said, a poor march. It looks like 300 would be relatively easy. However for me this being the first full year with the 3wp, happy to see the improvement month on month. 55% consumption which could be bettered for the month but is unlikely to rise really over the next few as production rises.

    410kwh total used, a fair bit being the tumble dryer which would be less used if we had better weather. So its possible to see this system being self sufficient for March.

    Figures are in for the month of March from a 4Kw system on an even East : West split. Based in South Dublin. No battery. 6kW inverter:

    • Total generated: 237 kWh
    • Highest day:  23rd 13.6 kWh
    • Lowest day: 9th 1.74 kWh

    Great to see the figures climbing now. Still unsure about the financial benefit of it all. August will mark the 12 month milestone so I’ll do up the figures then and see what it all looks like. No regrets whatsoever in going down the Solar Trail though. It’s the right thing to do.
