Using sunshine to cool down the car

처리 내용

If you would like to do that by the use of solar panels, the problem is power. A typical car AC probably uses somewhere between 1000 and 3000 watts. A square meter of typical photovoltaic cells generates roughly 150W of power. Even if you covered the entire car with solar panels, they wouldn't be sufficient to power the AC completely under perfect conditions. And they would be very expensive. The fans are much less power hungry, a couple hundred watts at most. You could technically run them off a solar panel alone if you don't need maximum power. Some car manufacturers do it already. For example some Audi models have a solar panel sunroof as an option. It keeps the blower fan running at low speed even when the car is off to keep the air circulating and fresh. For anything else, the solar panels simply do not generate enough power to produce a significant impact.
