Many car models use roof-mounted solar panels to power ventilation systems. For example, the Audi A6 used it more than ten years ago, the Toyota Prius also used it, and Mercedes-Benz also used it. They basically use battery panels to power the fan in hot weather. automatically ventilate without consuming car battery power.
There are also use cases for solar panels in campers and off-road vehicles. It's nothing more than powering the car battery. If the car roof area allows it, the power generated by the battery panel is considerable. For example, with a 4㎡ battery panel, the output power can reach 600w when the light is strongest. It is very convenient to replenish the vehicle's power supply. car. You should know that the capacityDischarge rate of a 60ah battery is also around 600wh. Therefore, when installing battery panels on the car roof, you should proceed from your own practical point of view. There is no need to add them to new energy vehicles, and the light intensity and lighting duration also need to be considered. the panels do not produce their full power at all times. Output power and light intensity, ambient temperature are all important.
