Essential Info

All attic ventilators, AC-powered or solar, vent out the hot air built up within the attic, but a solar unit offers additional benefits not possible with an AC-powered product. Because a Broan Solar Powered Attic Ventilator (PAV) turns on at dawn, it goes to work immediately, first to eliminate the moisture that has built up from the cool overnight air, and second to prevent heat build up before it has a chance to reach the point of convection. A standard PAV has to reach a high temperature before the thermostat kicks in and tells it to start working. By this time the moisture has already worked its way into the insulation and the walls, doing its damage. Because it has to play catch-up, the PAV is already starting out at a disadvantage and must run all day. Driven off AC power, a PAV can be noisy, emitting harmonic noise, and although it is possible to override the thermostat and let it run, the motor is not designed to handle this constant demand.
