    10kwp in the shade makes for some pretty brutal numbers, still FIT covered the bill so can't complain

    6.5kw system, south facing Limerick…160.85kw/h, down from 267.85 last Nov. 5.79 mwh for the YTD, last year was 6.06. Exported very little back to the grid in November and had a few car charges aswell…still, 2 years in having the solar panels, happy with the return, will look at getting a battery next year.

    Worst December since install for me

    Screenshot_20250101-094057.png

    Very few days hitting 4kWh. I do get a lot of shading this time of year, bear this in mind if comparing

    Screenshot_20250101-094025.png

    Practically nothing exported, and the battery was clearly not sufficient for the extra holiday at home load

    Screenshot_20250101-093929.png

    In real money this chipped away at the credit, plus I'm back to a standard 15% discount😬

    December 2024 108kWh from a 9kwp 22 panel E/W split which is about the same output as 2 good days in June. December last year was 122kWh- E/W really doesn't perform that well in the depths of winter.
