Yesterday the system generated only 0.16kWh, ie less than 10% of what might be expected for a typical March day! Worst day so far, under very gloomy dark cloud.
Today, however, we came within a few % of maxing the system out, peaking at 1.03kW against a nominal maximum of 1kW and an actual limit of 1.1kW.
Without watching the graphs myself I wouldn't have believed the intermittency of roof PV! It really is a learning experience, and it gives a feel of how difficult it will be for a grid operator to balance the system with ever-larger portions of unstored use-it-or-loose-it RE.
Still, that's the fun bit of engineering, surely?
