Yes, installing solar panels to your house can generate enough electricity to charge an electric car but not all-year-round and not to 100% capacity. As mentioned, the average battery capacity for an EV is 40kWh and if we based the average mileage a day at around 40miles this would use around 25% of the vehicles battery.
Solar panels are more or less current sources (50% sun=50% torque). The LCB takes solar panel power at low current and fixed Vmp (=Vmp*I sun) and converts to high current & low voltage used to start the pump motor). Solar panels, when there is, at least, weak direct sun, run a constant Vmp and low Isun current.
