The new professional grade, 20-watt solar panel with heavy duty ABS fan shroud and 20-galvanized steel housing and flashing. Will ventilate up to 2800 sq. ft. of attic space with a single fan. The smooth-air deflector in the shroud of the fan produces a smoother air flow and increases exhaust performance by up to 30% from previous models. This solar powered attic fan is our most powerful and efficient model yet that effectively reduce attic heat build-up in the summer months and moisture in the winter months. Lowering attic heat lowers air conditioning run-time by removing the heat build-up in the attic, lowering the attic’s temperature closer to the ambient outside temperature. Lowering attic temperature also adds the benefit of preserving and extending the life of roofing and attic construction materials. Additionally, hot air in the attic can heat the metal exterior of HVAC ductwork, consequently heating the air passing through it, causing the air conditioner to work harder. Adding a solar attic fan prevents mold and mildew in the winter by removing damaging moisture that contributes to mold and mildew growth. Moisture migrates into the attic space from daily household activities and warm attic air meeting the cold roofing materials creates condensation, which drips onto the attic insulation reducing its effectiveness. These warm attics in winter also contribute to ice damming, causing water to accumulate, adding the 20-watt solar attic fan helps prevents this.
