It’s important that you have plenty of ventilation in your attic to remove hot air in the summer and prevent condensation and moisture problems in the winter. In addition to soffit, gable, and/or ridge vents, you may want to add a power vent fan to your attic to increase air circulation.
Solar powered attic vent fans usually don’t move as many cubic feet of air per minute (CFM) as hardwired fans; but they’re much easier to install, since no wiring is needed. To determine the number of cubic feet per minute needed for a power vent fan, multiply the number of square feet in your attic by 0.7.
