Not much really but I used 5.2 MWh of electricity in a year and generated 3.4 MWh from the PV panels. Predicted generation was 2.6 MWh from the supplier so all seems good to me.
Getting the electricity usage lower is going to be hard because of an electric oven and running a lot of electrical equipment. Still I think I can get below 5MWh per annum easily and perhaps to 4 if I replace some appliances and/or install some building automation to control some things.
