Does your house connection provide 2 E car charging stations? You get about 10-12 kWp on the roof. Rather, only one charging station works there. Otherwise, you draw from the grid.
For East and West, smaller modules can also be tested in detail. Solarfabrik has the S5 with 1.65x0.88, placing 2 of these in parallel each and then all 4 to 1 micro-inverter. It's a bit of a gimmick but nice for the first and last hour of sunlight of the day.
