What should you look for when choosing one of these top rated solar attic fans?

Aside from the style of the unit, there are plenty of other aspects to look at in the specification. When looking at the fan element itself, pay attention to the width, pitch and durability. It needs to be long-lasting, but also effective enough to handle the size of the attic.

Most brands should highlight a recommended square footage in their descriptions. As for the panels, look at the wattage, the strength of the cells and the ease of adjustments. Can you angle to panel to meet the sun and will it survive a hail storm?

5 of the best solar fans to consider:

1. Brightwatts Solar Gable Attic Fan:

The first product to mention with these top rated solar powered attic fans is one that uses a separate fan and solar panel. These devices are popular with those that have larger spaces and need to make the most of the sunshine. They can be a little trickier to install than the options below, but the best are simple enough for first time users.

This Brightwatts Ultra Premium Industrial Grade Solar Gable Attic Fan has a 15.25’’ diameter with a 25 degree pitch on the blades and a brushless motor. This should increase air flow around that 1200 square foot space. It is all about the efficiency in the fan, not just the use of solar power. It is also built to last, with a promise of 30 years of use.

This is partly down to the use of rust-protected galvanised steel. The unit comes with a solar panel at 12.6W. It is basic but does the job. The panel also has high impact tempered cells to resist damage from the weather and a 25ft cord.


2. ECO-WORTHY 25W Solar Powered Attic Ventilator:

With this Eco-worthy solar attic fan there are more solar cells and a bigger area covered. This should therefore appeal to those with more space to ventilate. This time there are claims that the device can handle 2,200 square feet, almost double that of the Brightwatts model above.

There is also the promise of a great performance at la ow voltage, which means that those blades should keep spinning on cloudier days too. Furthermore, this is another product with a brushless motor to keep the noise down.

As for the solar panel, the specs here are also double that of the model above. There is 25W on offer in a large system. Another nice detail here is that the panel comes with mounting brackets so users are better able to find the optimal position for the sunlight. Finally, there is the 16ft cable, which is smaller than above but should still be adequate.


3. Broan Solar Powered Attic Ventilator:

This Broan solar powered attic ventilator doesn’t things a little differently to the top rated solar attic fans above. Instead of providing users with a typical fan and a connected solar panel, the panel is built into the system.

The upside to this approach is that there is a more streamlined system and greater ease of use. The downside is that there are fewer opportunities to position the panel in the optimal place.

This solar fan model is designed to handle 3,222 cubic feet of air – note that this is measure in air not the size of the room like the models above. The 12’’ diameter fan and 28W solar panel are built into a low profile ABS casing that should be tough enough to handle bad weather.

Another benefit to this design is that users can either choose a suitable wood effect or paint the device to match the roof. It should be a small, efficient solution for those that want minimal fuss.

4. Natural Light 36-watt Solar Attic Fan:

The design of this Natural Light solar attic fan is similar to that of the Broan. Once again there is that helpful all-in-one solution to help with installation. The first difference here is that this model has a more prominent solar panel with a 36W output.

This should allow for a reliable solution in the right climate. Then there is the fact that this is for pitch roofs only, with a separate model available for flat roofs.

Natural Light are proud of the construction of this device, stating that it contains some of the highest quality materials on the market. This allows for added peace of mind over the quality of the fan and adjustable panel.

The panel has a tilt that allows users to change the angle up to 45 degrees for improved coverage. The fan can cover 2625 square feet of attic space. This all means a reliable approach to summer ventilation.


5. HQST Solar Attic Fan:

The last of these top rated solar attic fans is another all-in-one solution. The approach is very similar to the model above. The unit sits within a pitched roof, with the opportunity to angle the panel up to 45 degrees. This adjustable 30W solar panel provides steady power to the fan to circulate the air in a 2625 square foot space.

The fan is also a little larger than some other models, with a 14inch diameter. Still, this shouldn’t cause too many issues when finding a suitable spot on the roof.

Users will also appreciate the fact that this HQST Solar Powered Roof Mount Adjustable Attic Fan has a tough construction for longevity. There is a rust-fee aluminium material that is durable but still light enough to handle. The quality of the cells and parts also means there is great protection from the elements.


Choosing the right solar powered attic fan for your home. 

The final choice here largely comes down to that decision between the all-in-one models and those with separate fans and panels.

The former has its benefits for ease of installation, and there are generally the same great features within. The choice between the models depends on the adjustability of the panel and the volume of air it can handle.

The latter takes a little longer to set up, but can be optimised for the best results. Here the best options have strong cells, quiet motors and long cables. Compare top rated solar attic fans carefully to find the best option.
