Fan for cars

We're realising our project might be too ambitious for a car; we tested our project with a small battery, and saw it was enough to move a small CPU fan. However, if we take into accont the 30% efficiency of a solar panel, and when in ideal conditions, it makes for low power. We wouldn't even know if it could power one or two small CPU fans. They take A LOT of energy when you think about it.

We were advised the following solutions:

-Find a solar panel that has a battery which you can connect, so you can use it with more efficiency

-Maybe don't use it in a car; just create a portable solar powered fan, which you could stick inside a stroller for example.

We designed our project and drawn it, using pvc tubes to get the hot air out, the fan to move the air inside the car and solar panel to power the fan.

Since we realised a small CPU fan takes a lot of energy, we needed a big solar panel. We ordered a big solar panel and looked up the amps, the voltage etc. We ordered multiple sizes of fans as well to see what wuld be optimal.
