Solar Attic Fan 24Watt

When the temperatures start to rise and the sun is out in full force, home owners will need some way to keep their home as cool as possible. Central air and window air conditioners do a pretty good job of creating cool temperatures in the home, but they add to energy bill costs. There’s a way to actually turn the sun into a home cooling option by installing a solar attic fan. The Solar Attic Fan by Natural Light is a good example of one of these clever cooling options.

Natural Light’s Solar Attic Fan runs on 24 watts of power provided through a solar panel module. The module is efficient enough to keep the fan running constantly without the need for any outside power source. It features a strong construction of aluminum with a powder coating, which is tough enough to match the metal found in aircraft. Although expert installation is available for those who need it, it’s not required, as all of the equipment needed to install the solar fan is included with the product, and there’s no need to run wires through the home to the fan because of the module.

The solar panel sits on a hinge so that it can be angled to get the most sun exposure. There is a lack of rotation once the fan has been installed, so it’s best to have an idea of the sun’s path before installation. The fan supports the installation of different roof types, even tile roofs using mounting hardware. Since the fan spins as longs as power is provided to it, many users opt to purchase compatible switches for fire safety and thermostats to control the temperature and turn off the fan during periods when it isn’t needed.

The solar fan also comes with a limited 25 year warranty that should cover normal usage. Due to being a solar unit, it’s possible to get a 30% federal credit from the government for the purchase of the unit.

The Solar Attic Fan by Natural Light works well as a cooling solution for homes. It can act as a supplement for air conditioning systems to reduce the load placed on them or work as a main cooling method if multiple fans are used. For over $350 a unit, it’s an affordable option as well. The lack of rotation may be a hindrance to some, but with careful planning before installation, this can be overcome.

Broan 345SOWW Surface Mount Solar Powered Attic Ventilator

The attic is perhaps the most important area of the house in terms of insulation and storage. While there are many styles of houses that don’t have attic storage space, most are. If nothing else, most homes have a crawl space where you can store a box or two.

Heat rises, so these attics have to be well insulated. However, heat loss isn’t the only problem an attic can have. In damp, rainy climates an attic can quickly become a great place to live for mold, fungus, and pests. So keeping it well-ventilated is a must.

The Broan model 345SOWW ventilation fan for the attic is a great choice if you’re looking for an inexpensive fan that works well. It has a number of features that make it much better than the standard metal fans.

Standard Fan Features And How This Model Is Better

Ventilation fans require a certain amount of energy to run. This causes people to only turn it on occasionally, which gives it less time to do the job. No one wants to use more electricity than absolutely necessary, and rightly so.

The model 345SOWW surface ventilation fan from Broan comes with solar panels so it can power itself. You won’t have to worry about a higher electrical bill with this fan!

Most attic ventilation fans are large, metal objects that don’t always hold up. They’re generally made of sheet metal, which stands up to weather fairly well but has a great deal of space. Screws can get rusty, and it’s easy for water and animals to crawl in.

Broan once again outclasses the standard by being small, surface mounted (so it sits on your roof rather than a wall), and built with an aluminum mesh protection screen. The surface mounting is an especially beneficial feature. It allows minimal cuts in roofing shingles, which ensures minimal space for water or vermin.

Even if the roof isn’t precisely flush against the fan, the mesh screen picks up the slack. It helps dissipate the water, forcing it to flow down further away from the fan itself. It also sits flush against the roof, keeping out everything that’s supposed to stay out.


Broan has made one of the best ventilation fans in its price range. While huge, fancy systems may offer a number of programmable features or boast impressive lasting power, the Broan model 345SOWW solar-powered surface mounted attic ventilation fan is the best value for the money you’ll spend.

Eco Worthy 25W Attic Fan

The Eco-Worthy is a 25W solar powered gable attic vent fan that is designed to be maintenance-free. As such, it comes with a 30W solar power panel that is foldable.


  • The 25-watt gable attic vent fan is powered by a brushless motor for quiet and smooth running. The fan is capable of venting up 2,200 square feet efficiently.
  • The fan has high-strength aluminum blades.
  • The fan comes with a high-strength stainless steel shell.
  • The ventilator has a pre-installed 8-inch cable with a connector for easier connection to the solar panel.
  • It has a 30-watt poly solar panel that is foldable. The solar panel also comes with an adjustable mounting bracket for better positioning and seasonal adjustments.

The Good

It has to be said, the Eco-Worthy is designed to be easy to use and work right out of the box. As such, there is not a lot you need to do to get it working, other than installing it. Being solar powered, it cools your roof without consuming utility energy. This reduces the load placed on your air conditioning and reduces the amount of energy bill you pay at the end of every month.

For the most part, the system is designed to be maintenance-free, meaning after you install it, you need not worry too much about it. Obviously, the occasional maintenance is required to enhance the performance of the system and to increase the life of the system and, therefore advised.

Another benefit of using the Eco-Worthy Ventilator is that it can work even under low voltage conditions. As such it can work even on cloudy days.

The Bad

A very annoying element that comes with purchasing the Eco-Worthy is that its installation can be a daunting process. For starters, it does not have a built-in mounting system that its users can make use of. Furthermore, since this item is produced as a kit, it does not come with any instructions on how to go about its installation. As such, for those who are not adept at DIY projects, this can be a huge limitation as its installation will be a daunting project.

Other users have an issue with the fact that the Eco-Worthy does come with its own screen cover for the fan. This means that insect pests have an easy time getting into one’s home if the fan is installed in its stock configuration without adding a screen.

The Bottom Line

Overall, the Eco-Worthy is a very capable ventilation system that is also a cost-effective purchase and low cost to maintain. At its price point, there are very few alternatives that can offer the same high-quality attic ventilation and still work straight out of the box.
