Solar powered attic fans or PV fans harness the sun’s energy to pull heated air from your attic while replacing it with cooler air. This reduces the work your HVAC system has to perform to keep the upstairs area cool. If you have a bedroom in the upstairs area of your home, you might’ve noticed how uncomfortably warm it can get during the summer season. A PV fan is perhaps the best solution to replace this warm air with the cooler from the outside.
There are other benefits to installing solar PV fans as well. These are:

Less Drain on your Air Conditioning System

The PV fan yanks hot air from your upstairs room and attic. By doing so, it is capable of lowering the temperature by several degrees. When the heat is pulled out, less of it scatters back into your home. This means your air condition system doesn’t have to work hard to keep the home cool. With a simple solar attic fan installation, you can save up to 30% on your a/c cooling costs.

Prolongs Roof Life

Even with vapor barriers in place, moisture is still able to creep into the upper areas and form condensation on the roof decking, attic insulation and framing boards. This problem is worse in older homes because they tend to be settled and have cracks in the foundation which enable air leaks. Solar fans can be a boon because they help to expel moist, warm air, thereby preventing the growth of mildew and mold. This enhances the lifespan of your roof.

Operates in Every Climate

Solar powered fans are made from weather-resistant panels. These are very durable and are capable of harnessing the sun’s energy in low light conditions. Since the fans operate without another fuel source, they produce no pollution with no negative impact on the environment.

Other Benefits

• Solar fans have zero operating costs.
• No electrical work or hookups are necessary.
• The entire assembly usually does not take more than an hour.
• Coupled with your home’s HVAC system, it makes your home atmosphere more comfortable.
