A Solar Power Car does not move at night using just solar power. While solar power is its main source of energy during the day, solar power cars typically have an additional energy storage system, such as a battery, that stores the energy generated by the solar panels during the day.
This stored energy can then be used to power the car at night or when there is insufficient sunlight. Additionally, some solar-powered cars also use regenerative braking to capture energy from the car's motion and use it to charge the battery.
