Are you searching the best solar attic fan?
Getting a high quality solar fan for your attic comes with multiple benefits. With that in mind I have reviewed the top models on the market and after reading this article you will know my recommendations.
Check out the quick list below for links to customer reviews and prices for my picks, or read on for the full review:
1) Cool down areas air conditioning does not reach
2) Reduce reliance on using air conditioning units
3) Ease of installation
4) Tax credits
Solar powered attic fans are widely selected for their ability to cool rooms that AC doesn’t cool efficiently while reducing reliance on AC. Add on top of that, they are incredibly easy to install, going with a solar attic fan is a game changer for those who want these benefits.
Installing a high-quality unit can decrease attic temperatures by as much as thirty percent while simultaneously reducing AC usage by six percent.
Solar attic fans can achieve this by taking the hot air that’s in your attic and pushes it outside while allowing cool air to travel through the vents. This drops the total temperature in the home allowing the AC to run less, leading to a decrease in energy usage.
The fans are not plugged into your electrical and are the included fan motor is instead run from solar power collected by the built in solar panel.
Some models come with batteries to allow the units to keep working even in low light conditions and at night.
Installation can be done by most homeowners without the need to call a pro.
One amazing benefit of going with a solar attic fan is that they are eligible purchases for utilizing the Federal Residential Energy Credit. This allows the home owner to take advantage of a 30% credit for the total cost of the unit and installation.
Some local and state governments offer additional tax incentives so check with your local administration for potentially larger savings.
How Many Do Your Need?
Solar attic fans can move different amounts of air depending on the model. The amount each fan can move is measured in cubic feet per minute, or CFM.
Generally, it is recommended that the average attic use a solar fan rated at least 1,000 CFM.
Each of my recommendations will handle up to a couple thousand square feet so most home owners will only need one solar attic fan.
The average attic stands at 1,600 square feet so if your attic is larger than that you will want to opt for multiple units.
Installation of the units on my list are very easy. You will need basic home tools and a couple hours time and you will have your unit up and running.
One key is to locate an area to install the fan and ensure that it is relatively centrally located. From there, a Sawzall is perfect for cutting out the section for fan placement. After the unit is placed you will need to follow the manufacturer instructions for sealing the perimeter of the fan. That’s it!
