Jimbo, see last link.
That size in electric run about $100. plus installation and operating costs. They need between 280 and 400 watts to operate.

Home Depot Attic Fan - Home & Garden - Compare Prices, Reviews and Buy at Nextag - Price - Review

These solars at HD seem to be about 250cfm, 15 watts and underpowered.

Edit: found this 1500 watt comparison online but I think the electric costs are overstated. Still looks good though.

Here's one at 1500 cfm for about $550, but if U shop they can be had for 400-450



The cost comparison on that link is about right.

Also you're reducing your carbon footprint with solar

I thought about the motorized screens, but if you're outside working in the yard it's too much trouble to keep putting it up and down. We went with the horizontal sliders, so you can open one section go and close it behind you. Also it's much cheaper, we paid $850 installed for our 12' door opening.

John,

I 100% agree with you about the screen being the best way to go. The screen also adds to the beauty of the neighborhood by concealing the contents of your garage when the door is open. Prop the attic stairs open a bit and the process of thermodynamics will take over and pull the "cooler" air into the attic and out the ridge and soffit vents. IMHO there is no real benefit to any kind of attic fan.

Also thought about some of the foam insulation being added to the inside of the door. I dint think we can have portable air conditioners?? Any suggestion Thanks

Try an exhaust fan

I extended my Golf Cart garage 27' down the side of my house and took out the back wall making it 42' long. I insulated the doors and the attic of the addition along with the existing garage. Finally I had a Mitsubishi 2 ton ductless AC unit installed in my garage. You can hang meat in the garage now. This is why I say it is "Too Cool Garage".
