Sounds like a whole house fan and like you found the perfect solution!

I bought a 30 watt solar powered fan and panel combo off of eBay for about $100, it moves 1550 cubic feet of air per minute when in full sun. I mounted the solar panel on the roof. I cut a piece of plywood the same size as the rectangle hole thing cover in the ceiling you use to access your attic, cut a hole for the fan, painted it to match the ceiling, wired the fan to the solar panel, and replaced the sheetrock rectangle with my contraption. The fan pulls outside air into the home, vents the home air into the scorching hot attic, cooling it down, which keeps the whole house cooler. It's not air conditioning, but it does work, and it doesn't cost anything to operate. The fan does run even under full overcast (of course slower) but then when the sun comes out and tries to bake the house the fan automatically ramps up and dumps cooler air into the attic. Our attic is still scorching hot even with the fan, however I used to be able to feel the heat radiating off the ceiling when I felt it, and that doesn't happen anymore. And I never had to cut a hole in the ceiling, roof, or any other part of the house.
