@notjustbikes Solar on suburban homes is a funny thing. At the latitude of Amsterdam, it can lead to demand evaporation for 7-8 months of the year if the home has a sufficiently sized battery.
The solar from a typical suburban home can carry 10-15 kWp of solar, leading to 7-11 MWh production per year in east/west configuration and 13-16 MWh production in a south facing ideal deployment.
There is a 1:10 production difference between January and June, though, so the household likely needs to buy power Nov-Feb, but will likely break even or almost break even in Mar, and not consume any power from the grid in April to September, and begin to load from the grid lightly on October.
Heating with a heat pump will have them but 3-4 MWh during winter.
(Numbers based on our 75 kWh/(year and qm) home, and our demand, but they seem to be applicable on a more general scale, too).
For power producers this means they have to supply power to homes like ours only for winter.
Fortunately wind + battery can actually do that without CO2.
