Our house's attic retains a great deal of heat during summer. While we now have a good layer of insulation between the attic and the rest of the house I wonder if it would be worth it to add some kind of exhaust fan. We live in a mid-Atlantic state so we have to contend with both 100°F summer days and 0°F winter nights.
The house still has the original slate roof so adding a typical roof-based system isn't an option. There are three small circular windows that provide some air flow, but not much. My thought was to install a fan in one of those windows to force a cross breeze during warm days.
Is this likely to save us any energy (given that the fan will have to draw some power)? Are there options for solar-powered small window exhaust fans out there?

There are solar-powered gable fans - an Air Vent-brand fan can be picked up at Lowe's for just over $200:
The solar panel is on a cord, so it can be installed in the most sunny area while the fan sits in the gable.
