In summer, temperatures can reach up to 160 degrees Fahrenheit or above. This warm air then permeates around your home, overworking your air conditioner. This results into higher electricity bills. The solar attic fan provides the solution.

The solar attic fan basically acts like an air exchanger. It’s equipped with fans that pull in warm air from your attics and exchanges it with cooler air from the outside. Since air inside is now cooler, your AC doesn’t have to be running that much.

Moreover, solar attic fans run on solar energy. That is, the fans spin faster and become more effective as it is exposed to more sunlight.

Solar attic fans are also useful during winters, according to solar powered attic fan reviews. Houses during winter usually produce warm air. Thus, it creates moisture when it meets with the cold underside of the roof. Moisture build-ups can result into molds and other damages into your home.

There is a variety of solar attic fans available in the market. Most solar attic fans can be installed and mounted on roofs, gables and curbs.

How Does It Work

Like all solar products, the solar attic fan runs on solar energy. Solar attic fans basically act as the gateway between cool air and warm air and thus, help in regulating the temperature inside your home.

The solar attic fan runs on two essential components: the solar panel and its fan.

The solar panels are responsible for collecting solar energy. The size of the panel depends on the model one bought. The size and capacity of your home is also a factor to consider.

The fan inside the solar attic fan is in charge of the actual ventilation. The fan’s speed varies depending on the solar energy it got.

The solar attic fan can be used in all climates, especially during summer and winter months.

In summer, attics can usually reach up to 140 degrees Fahrenheit or hotter due to constant solar exposure. This heat then disperses around your home, resulting into an overworked air conditioner and higher electrical bills.

A solar attic works by exchanging the warm air inside with the cold air outside. Little by little, the living space can get cooler, resulting into reduced electricity consumption.

In winter times, there are tendencies for moisture to build-up as well when the warm air inside your home meets with the cold underside of the roof. Moisture breeds molds, which can damage your home.

The solar attic solves this problem by exchanging the warm air inside for the cold air inside. This way, you will have a drier roof and attic.

What Are The Different Types Of Solar Attic Fans

Attic fans are a popular alternative to use instead of air conditioners. For one, they’re cheaper and they basically give the same effect as that of air conditioners.

There are three types of attic ventilations.

First are your non-mechanical attic fans. Also known gable vents, they are mounted in the attic’s side walls. They are effective in cooling the attic. However, they have the tendency of causing heat spots when there’s no air.

Second are the electrical attic fans. As the name implies, they run on electricity, and thus are more powerful compared to the solar and wind-powered attic fans are. The downside, however, is that they can consume a lot of electricity that can put off some homeowners.

Third type is the whole house fan systems. Here, the attic fans are placed around the home to ventilate it. Since there are many, these systems are typically noisy.

Fourth are the wind-powered attic fans. They help reduce electrical expenses; however, they are not really reliable and consistent.

As such, they are quite popular among home and building owners.

Next, solar fans can also be installed either in gables, the gable vents or inside the attic. These types are usually meant to prevent moisture build-up.
