On a sunny day, indoor temperature can rise like an oven. Our solar vent fan, powered by a 10W solar panel is designed to reduce indoor temperatures by as much as 40º F with maximum efficiency and whisper quiet operation. The environmentally friendly solar fan can provide optimal ventilation to improve air quality, minimize moisture and reduce energy costs. Our solar fan can ventilate up to 200 square feet of space, removing up to 120 cubic feet of hot, humid, stale air per minute. Our solar vent fan, powered by a 5W solar panel, is perfect for cooling your hot attic, garage, cabin, RV, boat, basement, greenhouse, trailer, or other medium-sized space. Or, use it as an exhaust fan in your shop or studio. 10 feet of wiring is included. 

In an attic, where summer temperatures can reach 160 degrees F, ventilation cools lower-level rooms, reducing the need for air conditioning by up to 30% and extending the life of a shingled roof.

With a properly insulated attic, attic vent fans help in the winter too, by removing humidity and avoiding roof damage caused by ice dams.

This fan installs easily in a 4" hole with no 120V wiring needed. Fan automatically starts when the sun is shining on the solar panel. Quiet operation. Comes with 18" of wire, more can be added (use minimum 16g wire).

According to the Department of Energy, the most common energy-related mistake homeowners make is to cover soffit vents in the attic with insulation. If your attic soffit vents are covered and the attic is not well-sealed from the rest of the house, an attic vent fan will suck air-conditioned air from the living space into the attic.
