keep your cool…and hang onto your cash!

Anyone who’s heard of a “rolling blackout” knows that summertime electricity demand to run air conditioning takes a toll on the power grid as well as your wallet. Be part of the solution–and cut your cooling costs substantially–by installing a solar-powered attic fan from Solargreen! Our attic fans pay for themselves very quickly because they’re inexpensive to start with, cost nothing to run, require no electrical hookup, are maintenance-free, and reduce excess heat right at the source.

Our easy-to-install attic fan is a single, round unit set into the rooftop of your attic space. A solar power panel on the top of this flat unit converts sunlight into electricity, which in turn powers a lightweight fan under the solar panel. Whenever the sun is shining, the fan operates, drawing heat and moisture out of the attic through the unit’s vents, located just under the solar panel. (Solar conversion kits are also available to convert your existing roof vent into an eco-friendly, solar-powered one.) As a result, it takes less energy to cool your house in summer. In winter, this same ventilation reduces moisture buildup, which can turn to ice or frost and damage roof structures, saturate insulation, and promote mold decay and plywood delamination.

Solar conversion kits can also convert any existing roof vent into an eco-friendly, solar-powered one. Solar attic fans are maintenance-free, require no power source or electrical hookup, and cost nothing to operate. Any sunny roof location can help you save money on cooling costs for the life of your home or building.
