We managed 66.8kWh yesterday with 15% absorption on the Victron system. I'm not sure if it is a PB but it's gotta be up there.

20th May was our perfect day (1 of only) but the Solar Bootroom was not active then. Guess I'll have to wait until next year to see it all crack 70kWh. Unless today is very special?

Hopefully snuggy will be on the scoreboard by then. 🤞

WeatherPro, I pay a small subscription, about a tenner a year which gives higher resolution data, but you can use it for free.

The panels rely on irradiation to generate electricity. Fortunately on most days any clouds cover is thin enough. So meaningful volumes of power can be generated due to the oversized array.

I've never counted the strings, turns out we have 11 in total. Some are only single panel so more a stringette in that case.

Size doesn't matter (apparently). :twisted:
A mere low 60's kWh today. SWMBO has left (EV too) for Turkey with a chum so I'll be unlikely to keep up with the panel output next week and a half. I actually ran up a couple of SH's today and it's really nice.

Another reason to switch from deemed export to metered export, then the grid becomes your dump load to keep your charge controllers in business.
