13 best solar powered attic fans

Solar-powered attic fans are devices designed to ventilate and cool the attic space in residential buildings using energy from the sun. They offer several benefits for homeowners and are related to roofing, building materials, building supplies, and home improvement.Here are some key points about solar-powered attic fans:

  1. Energy Efficiency: Solar attic fans are powered by photovoltaic (PV) solar panels mounted on the fan housing. They use sunlight to generate electricity, making them energy-efficient and cost-effective in the long run.

  2. Ventilation: The primary function of a solar attic fan is to promote proper attic ventilation. During hot weather, attics can become excessively hot, which can lead to a range of problems, including increased energy costs, reduced roof lifespan, and potential damage to stored items. These fans help remove hot air, moisture, and heat buildup, thus maintaining a more comfortable and stable temperature in the attic.

  3. Improved Energy Efficiency: By reducing attic temperatures, solar-powered attic fans can help lower the overall temperature of the entire house. This can reduce the workload on air conditioning systems, potentially leading to energy savings and increased comfort in living spaces.

  4. Moisture Control: In addition to regulating temperature, these fans also help prevent moisture buildup in the attic. Excess moisture can lead to mold growth, rotting of wood structures, and damage to insulation. Solar attic fans help mitigate these issues by expelling moist air.

  5. Easy Installation: Solar attic fans are relatively easy to install since they don't require a connection to the electrical grid. They are typically mounted on the roof or in the attic, and the solar panels are positioned to capture sunlight.

  6. Quiet Operation: Solar attic fans are generally quiet in operation, making them unobtrusive and suitable for residential use.

  7. Longevity: Solar attic fans are designed to be durable and require minimal maintenance. Many models come with warranties, ensuring their longevity and reliability.

  8. Environmental Benefits: Solar-powered attic fans are eco-friendly as they reduce the need for electricity generated from fossil fuels. They help reduce a home's carbon footprint and contribute to a greener environment.

  9. Cost Savings: Although the initial cost of purchasing and installing a solar attic fan may be higher than conventional attic fans, the long-term savings on energy bills and potential HVAC system longevity can make them a cost-effective investment.

  10. Different Models: There are various models and sizes of solar attic fans available to suit different attic sizes and climate conditions. Some may include additional features like adjustable solar panels or backup batteries for continued operation during cloudy days.

In summary, solar-powered attic fans offer an energy-efficient and eco-friendly solution to regulate attic temperatures, improve energy efficiency, and prevent moisture-related issues in residential buildings. They are a valuable addition to roofing and home improvement projects, contributing to a more comfortable and energy-efficient home.

User questions & answers

Question: What is the warranty
Answer: warranty for a year for the fan,5 year for the soalar panel, totally take responsible for damage or lost in transit. Any issue will be followed by professional customers service team.
Question: Has anyone gauge the attic heat tempreture reduction as a result of using this
Answer: I did not measure the temperature difference, but it did not seem to make a difference. The fan does run quite strong so I suspect that it does pull heat out of the attic (that is, after you reverse the fan in its shroud so that it blows outward). However, I was very disappointed, after the fan motor completely died after two years.
Question: Can this get wet? Weatherproof
Answer: I mounted it in the roof gable vent and covered it with the slotted vent cover, so it doesn't get wet unless the rain is horizontal. Anyway, the motor burned out after two years. I don't recommend this product. I'm going to remove it and install a hard-wired electric attic vent fan.
Question: Can someone recommend a thermostat to install with this fan
Answer: It does not have a place to plug in for a thermostat. I purchased a thermostat and did not use it. I have installed others that have a place to just plug a thermostat in. I would search for one of those fans.

User questions & answers

Question: How do i get the free thermostat
Answer: What? There’s a free thermostat?
Question: do you have to fill the gap when installing fan in gable vent? video showed using cardboard to fill gap at top
Answer: Yes, I had to build a frame to hold mine exactly in the center where I wanted it. I cut plywood to nail and fill gaps to prevent pollen and debris from flying in through the sides since it only runs on full sun. One cloud and it turns off!😕 I will eventually switch it to the other side of attic to just circulate the air. Will replace it with a fan that runs 24/7 to prevent pollen and dust coming into attic.
Question: can it be used in a greenhouse
Answer: I'm using it in a solar wood kiln, I'm assuming that the conditions are similar enough to say yes. Had a sunny but frigid day with a high of 5 degrees, the fan worked fine. The temperature inside the kiln in summer reached above 110 degrees, it still worked well. Humidity and temperature don't seem to affect the performance of the fan whatsoever.
Question: Our cottage's roof faces east in the am and west in the pm. so my question is can we install a panel on each side of the peak
Answer: Yes you can

User questions & answers

Question: Is it thermostatically controlled
Answer: If you mean is it easy to see the positive & negative wires going directly into the fan, cut & splice your own switch in, bypassing thermostat.... yes it is easy to do.
Question: is the fan on the roof line or deeper
Answer: I think sealed, I don't remember any zerk fittings or oil holes to use. Mine has been in my house two years and there are no problems. I by passed the thermocouple and have it on a switch. I put one in my daughters house and used the thermocouple because she and her husband are gone quite a bit and not at home to turn it on. No issues after 18 months. Quiet because I used rubber padding between the fan and board it is connected to. It keep our upstairs a lot cooler. No issues with bearings yet, and I don't really expect any.
Question: Can this be install to an indoor patio? I have a room where the ceiling is essentially a shingled roof with no insulation or space inbetween
Answer: The thermostat is inside the fan--look at the picture, it is the little box in the lower left corner where the electrical wire is running into the fan. You can take the thermostat out as it is only attached with a couple of screws. Mounting it a few feet away from the fan is easily doable.

User questions & answers

Question: I have a 2600 sq. ft. single level home. Would it be better to install 2 30 watt attic fans

Question: I have a metal roof, any way I can install it
Answer: Depends on how deep the gap between the walls are. If you have a crawl space i between the wall. It will not work and you will need a vent extension/ ducting to fit the fan. If the gap is less than 4 inches. You it will work. Also you will have to drill out the hole for the fan. I would suggest having a profesional install the fan.

User questions & answers

Question: so without the thermostat, does this fan run all the time while it is light out
Answer: Yes, it runs continuously when it receives light. You may purchase a Broan thermoswitch which will shut it off if the temp is less than 50 deg F (which means it'll basicaly run all the time). I purchased the thermoswitch for the Natural Light brand because it turns on at 80 and off at 70 (added benefit: it's cheaper). For my climate in Los Angeles, that range is preferable (I would think the same in other climates, too). To install, just clip off the black male spade connector of the Broan and replace it with a female and reconnect with the switch in series. The wiring that comes with the switch is not used. It's easy and it works!
Question: Can this fan sustain hurricane winds
Answer: Our unit is located on the Ocean and we have had storms but no hurricanes since it was installed.
Question: Can this be installed on a Terracotta tiled roof
Answer: Only if the tiles are relatively flat. Broan's website indicates the fan is designed for a "shingled" roof. Not much clearance between the base and the fan housing, but it woks great.
Question: Will these keep the dampness out of a shed? Shed is only 140 square feet
Answer: This fan is designed for spaces of 3200 cubic feet. We would not recommend using this fan in a small space. Please contact our Technical Support Department at 800-637-1453 for assistance in determining the best fan for your needs.

QuietCool 40 Watt Solar Powered Roof Mount Attic Fan

QC Manufacturing, Inc.

Based on 90 reviews Check latest price

Product description

QuietCool Solar Attic Fans are the best in the industry offering the largest panels at an affordable price. This fan features a 40 watt solar panel, a preset thermostat, an ultra-energy efficient DC motor, a heavy duty steel housing, and an included AC/DC inverter. Solar attic fans work by using sunlight to power the fan’s motor to help prevent any heat or moisture build up in your attic. Your attic can reach temperatures of up to 150 ºF which can destroy the integrity of your home as well as completely destroy your roof because of the humidity and moisture build up. Because of this, solar attic fans can prolong the life of your roof structure and air conditioning while helping you save up to 30% on A/C costs. With a QuietCool Solar Attic Fan, you also get the benefit of an included AC/DC inverter. This allows the fan to run 24/7. When there is sunlight outside, the fan will run only on solar power being powered by the large solar panel on the fan. When there is no sunlight, such as at night, the fan will switch to AC power and continue to run throughout the night. This allows you to take advantage of cooling your attic during the coolest part of the day. Simply mount the fan to your roof and plug in the inverter to enjoy 24/7 cooling and ventilation in your attic.

  • 40 Watt Solar Panel
  • Ultra-energy efficient DC motor
