DIY Weak Solar Powered Car Exhaust Fan

I thought solar power had come a long way. While strides have been made, this 1.8 watt panel has trouble working without direct sunlight. It has a cool blue light that lets you know when it is getting power, however, it does not equate to full power. The fan requires 0.19 amp, and the panel puts out about three quarters of that in good light, so perhaps I am asking too much from it. Needless to say, this did not lower the temperature of my car while sitting in the sun an appreciable amount. For that, I needed to go bigger.
