Photovoltaic array of 9 cells installed on my roof today. Weather is overcast, season is early Autumn, time is mid-afternoon. The system inverter has its own wi-fi dongle so I can monitor power production which is currently (pun intended) 2.88 kW. Whist it is connected to the national power grid, I'm not getting any credits for it until my power supply company signs me up to a rebate plan which can only be done after the final electrical safety inspection.
So the home power usage comes first from the solar array and any excess above that comes in from the grid.
I'm doing a load of laundry at present to make use of the generation capacity.
