Frequently Asked Questions About Solar Attic Fans: A Buyer's Guide for Austin Residents

As the hot Texas summer season begins to roll in, Austin residents will begin looking for ways to reduce their energy bills and keep their home cool and comfortable. This is where solar attic fans can come in. These powerful fans are designed to pull hot air out of your attic, venting it outside and lowering attic temperatures by up to 30°F. This cooler air helps reduce air conditioning costs in the summer and could even help prevent premature aging of your roof, helping to preserve its shingle life.

So what is a solar attic fan? Where can you find one and how do you know which one is right for your home? To help answer all these questions and more, we've compiled this list of frequently asked questions about solar attic fans. Read on to learn more.

What Is a Solar Attic Fan?

A solar attic fan is a device that uses small solar collectors to draw energy from the sun and power an exhaust fan. This fan is mounted onto your roof and typically looks like a small circular vent with a louvered cover. This exhaust fan is designed to create pressure differentials in your attic, pulling out hot air and pushing in cooler outside air. Most models come with an adjustable thermostat and a water-resistant switch that turns the fan on and off automatically.

What Are the Benefits of Installing a Solar Attic Fan?

Since solar attic fans use energy from the sun, installing one can significantly reduce your electricity bills and save you money in the long run. Additionally, they can help with indoor comfort by reducing attic temperatures up to 30°F, allowing your air conditioning unit to operate more efficiently. Keeping the attic temperatures from getting too hot will also help to preserve the shingles on your roof, preventing premature wear or replacement.

What Types of Solar Attic Fans Are Available?

When it comes to solar attic fans, there are an array of sizes and designs to choose from. Most are circular ducted units that vent your attic air up and out of the roof. You can opt for a standard single-blade fan, or you can select higher-end models with dual- or triple-blade fans for optimum air movement.

In addition to size and blade number, you will also need to choose between a ducted fan and a non-ducted fan. Ducted fans are attached to the roof, with a ductwork system venting the hot air outside. Non-ducted fans blow the air into the attic, which can be useful if your home lacks adequate ventilation.

How Do You Choose the Right Solar Attic Fan for Your Home?

Choosing the right solar attic fan for your home can be a difficult task, especially if you are a first-time buyer. So here are a few tips to help you make the right choice.

First, consider the size and number of blades in the fan. Dual- and triple-blade fans are usually more powerful than single-blade models, so they can move more air more quickly. Also, be sure to look at the control options for the fan. Many models come with adjustable thermostats and switches that allow you to control the fan's operation.

You will also need to consider whether you want a ducted or a non-ducted fan. Ducted fans can be useful for homes with little attic ventilation, as they can exhaust the hot air outside. However, non-ducted fans may be a better option for homes with plenty of attic ventilation, as they can help circulate air more effectively.

Finally, think about the roof type that the fan is designed for. There are fans that are specifically designed to work with metal roofs, as well as models that are built to install into shingle roofs.

Where to Buy a Solar Attic Fan?

Solar attic fans can be purchased from a variety of retailers, including home improvement stores, online shops, and specialty solar equipment suppliers. You can find a wide range of different models to fit your needs, and they usually come with helpful instructions and warranties.
