Yesterday I managed 26.73kWh, seemingly a much better day than some! 11.67kWh exported.
Today, a different story, I'm on 15.4kWh as it stands so far and I'm still producing about 500w so there's a small chance I'll pass 16kWh by the time darkness arrives. No chance of more export though so I'll finish the day on 4.6kWh exported.
