Remove heat from the attic in summer, help prevent moisture and ice dams in the winter without using any electricity! Energy saving solar powered attic ventilators also reduce energy costs by reducing running time of air conditioners. Easy retrofit can easily replace standard powered attic ventilators.
Benefits of a Solar Powered Attic Ventilator....All attic ventilators, powered or solar vent out the hot air built up within the attic, but a solar unit offers additional benefits not possible with a powered product. Because a Broan Solar 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 build up to 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.
