Top 5 Things to Consider for a Solar Attic Fan

Constructing and installing a solar attic fan is an excellent way to boost the comfort and energy efficiency of your home or property. Solar powered fans are growing in popularity thanks to their low operational costs, ease of installation, and the fact that they're low-maintenance and don't require any complex wiring. If you're looking to install a solar attic fan into your home in Round Rock, Texas, it's essential to consider these five key factors for an optimal and stress-free installation.

1. Solar Attic Fans vs. Electrical Fans

When considering solar attic fans, it's important to weigh the pros and cons of wiring a traditional electrical fan vs. going with solar. Electrical fans, while a viable option, require specialized wiring and installation techniques, and a licensed Abacus Plumbing Electrician to do the job right. For solar attic fans, however, they typically fall into two different categories: an integrated fan and frame unit or a fan retrofitted to fit the existing frame. Solar fans require less technical know-how but may be more expensive.

2. Installing the Solar Attic Fan

There are three main elements to consider when installing a solar attic fan: roof penetration, frame installation, and general performance. Roof penetration is exactly what it sounds like — it's the process of creating an opening in the roof to install the fan. This process requires careful planning and precision to ensure a secure and long-lasting installation — if done incorrectly there's potential for leaks and degraded fan performance.

Frame installation consists of securing the fan frame securely to the existing rafters and trusses so it won't wobble in windy conditions or accumulate debris. When installing the fan frame, you'll also need to pay attention to small details such as fit and clearance, ensuring enough space exists between the fan below and any other roof penetrations, and keeping the frame level.

Finally, you'll want to check for general performance issues as well. If a solar attic fan has been installed correctly, the fan should run quietly and consistently, provide ample air flow, and keep the attic air temperature closer to that of the outside, improving home comfort and energy efficiency.

3. Ventilation

One of the primary benefits of installing a solar attic fan is the additional ventilation it provides. When the fan runs, it pulls cooler air from outside the home in, and this helps keep the internal temperature of your attic cooler as well. This is especially beneficial in areas like Round Rock, Texas, where temperatures regularly reach the high 90s during the summer months.

On the other hand, if too much ventilation can be an issue, especially for properties located in cold areas during the winter months. With too much ventilation, the temperature of the attic can drop too low and potentially create an icy buildup on the roof that can be dangerous.

4. Wattage

When selecting a solar attic fan, it's important to consider the wattage of the unit you choose. Many solar attic fans range from 10-watt to 40-watt — when selecting one, you should consider your climate and specific geographical location, and choose the wattage accordingly. Homeowners in Round Rock, TX, for instance, with lots of direct sunlight, may want to select a fan with a wattage on the higher spectrum.

5. Warranty

No solar attic fan is infallible — eventually, all mechanical parts will need to be replaced or they'll stop working altogether. The warranty of the fan you choose can go a long way in ensuring you get the most of it and save money on repairs over its lifespan. Most reputable solar fan companies will offer a limited warranty — be sure to ask questions and understand the exact details of the warranty before making a purchase.

There are five essential factors to consider when installing a solar attic fan in Round Rock, Texas: solar fans vs. electrical fans, installation process, ventilation, wattage, and the fan's warranty. By understanding these factors, you can be confident in selecting the right solar attic fan for your home. When you think you're ready to get started, contact a licensed technician for help and guidance.
