Keep Your Attic Cool with a Solar Powered Vent

Share this on:

When it’s hot and sunny outside, your attic can feel like an oven, but you can keep it cool all day long with a solar powered vent.  These vents use the power of the sun to operate and ventilate your attic from sunrise to sunset, when you need it most.  Many homes have conventional roof louver vents which don’t actively ventilate your attic space.  Other homes use electric vents regulated by thermostats, but these are not an energy efficient and pollution-free solution, like solar powered vents.  The installation process is much simpler for a solar powered vent since there is no need for electrical hook-up or electricity. Plus, they cost nothing to operate!

By using a solar powered attic vent and keeping your attic cooler with less humidity, you’ll decrease the load on your air conditioning system, saving you even more money. These devices will keep your home comfortable and even help prevent mold and mildew buildup.  They’re even beneficial in the winter as they aid in equalizing the temperature between inside the attic and the cold outside air. This dramatically reduces the risk of ice dams forming at the eaves.

The upfront cost for a new solar powered attic vent is a few hundred dollars, but it’ll start saving you money the moment it’s installed.  Plus, it qualifies for a federal energy efficiency tax credit of 30% of the cost.  Some states offer additional tax credits as well.  Different models are available to accommodate attic spaces of up to 1200, 1600, or 2000 square feet (multiple units can be used for larger attics).

    Ventilation is a tool to try and manage a problem not solve it. Ventilation only slightly reduces attic temps. Good insulation between the attic and living space will greatly improve the comfort level in the home. I have been an insulation contractor for 33 years and found out very early on that ventilation does not solve these problems it is the simple answer that a roofer or general contractor would recommend to a homeowner. Think about what adding ventilation does to the conditioned space in the winter without adding insulation. That’s right, sucks the heat out!

    Great idea. Thanks for passing on the information.

    John, thanks for bringing up a good point about properly insulating one’s attic. Ventilation is also helpful. Hopefully, my readers have seen my articles about the importance of insulating one’s house properly and also the green options available today, such as recycled cellulose and denim, as well as soy-based spray foam.
