frequently asked solar fan questions

We get a lot of questions from customers who are new to solar attic fans. So, we thought we’d put together a list of the most frequently asked questions.

Question 1: Are Solar Attic Fans Quiet?

Answer: Yes. A properly installed solar attic fan is so quiet that you will barely notice it is there. It can be installed in your living room and it will be quiet enough that you will forget it’s there.

Question 2: Do Solar Attic Fans Run At Night?

Answer: This is probably one of the most common questions we get. No. A solar-powered fan relies on UV rays to run. When the sun goes down, the solar attic fan turns off because it is no longer being powered by UV rays and does not store energy in a battery. However, the fan still acts as a passive air vent when it is off. Your attic is heated by the sun during the day. If your attic fan is hard at work all throughout the day keeping your attic cool, then, come evening, it can turn off, go into passive mode and your attic will stay cool throughout the night.

Question 3: Do a Solar Attic Fan Have an On/Off Switch?

No. The solar attic fan has a built-in thermostat that turns the fan on the moment the temperature in your attic reaches 80 degrees. You never have to worry about turning your solar fan on and off. It is completely automated and does all the work for you.
