13 best solar vent fans

Solar vent fans, also known as solar attic fans or solar roof fans, are energy-efficient ventilation devices designed to improve the airflow and reduce heat buildup in attics and other enclosed spaces within a building. They play a crucial role in maintaining a comfortable and energy-efficient indoor environment. Here's what you need to know about solar vent fans:

  1. Solar-Powered Operation: Solar vent fans are powered by solar panels installed on their surface. These panels capture sunlight and convert it into electricity, which drives the fan's operation. Solar power eliminates the need for grid electricity, making them a cost-effective and environmentally friendly solution.

  2. Heat Reduction: Solar vent fans are primarily used to expel hot air from the attic or enclosed spaces. By continuously moving hot air out of the area, they help regulate temperature, preventing heat buildup. This, in turn, can reduce the strain on your home's cooling system during hot weather.

  3. Moisture Control: Solar vent fans also aid in moisture control by reducing condensation and preventing the growth of mold and mildew in enclosed spaces. Proper ventilation helps maintain a dry and healthy environment.

  4. Energy Efficiency: Solar-powered attic fans are highly energy-efficient because they operate without consuming electricity from the grid. They work quietly and cost-effectively, helping to lower your energy bills.

  5. Easy Installation: Installing solar vent fans is typically straightforward. They can be mounted on the roof or in the attic, depending on the design. Minimal wiring is required, and no additional electrical work is necessary.

  6. Automatic Operation: Most solar vent fans come with built-in thermostats and/or humidity sensors. These sensors activate the fan when the temperature or humidity levels reach a preset threshold, ensuring automatic operation when ventilation is needed.

  7. Durable and Weather-Resistant: Solar vent fans are designed to withstand various weather conditions, including rain, snow, and extreme temperatures. They are constructed with durable materials and sealed to prevent water ingress.

  8. Extended Roof Lifespan: Proper attic ventilation facilitated by solar vent fans can extend the lifespan of your roof. By reducing heat and moisture buildup, they help prevent premature deterioration of roofing materials.

  9. Environmental Benefits: Solar vent fans contribute to environmental sustainability by utilizing clean and renewable solar energy. They reduce greenhouse gas emissions associated with traditional electric fans.

  10. Improved Indoor Comfort: Solar vent fans can lead to improved indoor comfort by preventing heat from radiating down into living spaces, especially during hot summers. This can result in a more pleasant living environment and reduced cooling costs.

  11. Compliance with Building Codes: Some regions have building codes that require proper attic ventilation, and solar vent fans are an effective way to meet these requirements while also enjoying energy savings.

In summary, solar vent fans offer a practical and eco-friendly solution for improving attic ventilation, regulating temperature, and reducing energy consumption in buildings.Their automatic operation, ease of installation, and long-term cost savings make them a valuable addition to roofing systems and building materials.

User questions & answers

Question: Can this be mounted on a wall
Answer: Yes you can, apart from the sunlight angle
Question: Does it have a screen to keep insects out
Answer: We do not carry a screen at the moment
Question: How do I get a/c Add on
Answer: Please call us for the ac power kit
Question: How do I calculate the wattage of a solar attic fan
Answer: Watts are the result of multiplying the operating voltage times the draw max current. (W = E x I). Your operating voltage on an AC fan is 120 volts. The operating current is posted on the manufacturer's label on the fan. Multiply one by the other and you get your watts. On a DC system like solar or batteries the voltage is the max output produced and the current (I) is also on the label.

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: 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.

User questions & answers

Question: What does ‘DBD’ mean
Answer: The BDB stands for builder series which includes a 110 hybrid adapter to make your fan run at night if necessary.
Question: What level of humidity is the humidistat set at? Are we able to also change the settings (raise or lower the threshold for both temp and humid monitor
Answer: The thermostat and humidistat is factory set at 80° and 75% relative humidity. Once the fan since is more than 75% relative humidity in the attic it will turn on and back off down to 50%. This primarily is important in the winter when there is moisture in the attic that needs to get out. The settings are factory set and cannot be changed. Our Wi-Fi thermostat/humidistat (sold separately) will allow you to make changes.
Question: What the watts on the fan for running on ac power
Answer: I have a 40watt and I purchased a 30watt for my daughter's house. Both are working well.
Question: Will it mount on any roof pitch
Answer: Yes. The solar panels are adjustable too.

User questions & answers

Question: Will this work in a small walk-in closet or pantry? Or underground seller
Answer: As long as the sun is shining on the small panels it working. I’ve installed two in the roof of our RV & they seem to keep the moisture out
Question: Does this blow air out of the building, like a shed
Answer: It doesn't "blow air" as much as it gently moves air. It's more passive ventilation than an active blower.
Question: What keeps water or rain from entering your interior
Answer: There is a rubber seal bike gasket that goes around the outside of the ventilator. When you tighten down the screws it creates a seal. If you wanted to you could put some silicone on this gasket for peace of mind. I did not use silicone and I've had no leaks.
Question: What is diameter of the hole needed
Answer: The hole needs to be about 4 3/4 inches to mount.

Product features

If you’re looking for an easy way to ventilate your boat, shed, greenhouse or caravan, this is one perfect choice for you!

  • Having an exhaust fan installed is one easy way to eliminate hot and moist air from your shed, keeping it cool and dry which in turn helps to prevent structural defects and health problems.
  • What makes it good is that it functions efficiently even at night as it comes with an inbuilt battery that recharges during the day and provides you with continuous operation at night.
  • For the sake of efficiency, this requires sufficient sunlight to power up the fan, and it is less efficient during cloudy days.

2.The solar vent fan is for small place such as yacht, boat, RV, trucks, dog house, vans, small greenhouse etc.. If your place is very big and wide then this vent may not be appropriate.

Solar Roof Vent - Solar Attic Fan - Solar SlantBlaster Weathered Bronze - Slantback Vent Style

Based on 18 reviews Check latest price

Product description

Trapped heat and moisture in one's attic not only diminishes the comfort of one's home, but they also reduce the life expectancy of your entire roof. This product is an ideal ventilation choice for your home, garage, storage/garden/utility shed. It works whenever the sun is shining! It needs sunlight to work!



CONTENTS:

The Solar SlantBlaster Fan comes pre-installed on a 9" metal slantback roof vent with flashing (16"x30.3").

A 3W solar panel will be attached to the top of the vent hood by four unique, stainless steel clips

 A two-ball bearing, 2700rpm, 39cfm fan that is rated for 50,000 hours.



Unlike the plastic vents of many other products on the market, these metal vent are designed to last on a lifetime roof. Plastic will fade and become brittle over time especially on top of a hot roof.



INSTALLATION: Install the vent as you would any roof vent to code. This product does not allow you to install less vents. Its benefit is to boost the effectiveness of your passive roof ventilation system with the power of the sun!



HOW MANY FANS SHOULD I ORDER FOR MY ROOF? We recommend one for every 600 sf of roof area. A typical home (1200sf) would take 3-5 vents. It is crucial that a home's attic is ventilated uniformly across the entire attic space. That is why most homes have numerous passive vents or ridge venting installed. The idea is that cool air will come in from the eave's soffit vents and run along the entire roof deck to escape at the top through the passive vents. This uniform air movement helps keep your roof's deck (the plywood, the trusses, and the rafters) dry and moisture free. It also helps keep your insulation's r-value from decreasing due to condensation dripping down from the roof deck.



DOES THIS FAN INCLUDE A THERMOSTAT OR ON/OFF SWITCH? No, it is not needed. Ideally, the fan should run in summer, to remove excessive heat, and in winter, to remove moisture due to condensation.

  • Solar-powered roof and attic ventilation fan
  • Panel: 3W solar panel
  • Fan: 2 ball bearing; 2700rpm; 39cfm; rated for 50,000hr
  • Base Metal Flashing: 16"x20.3"
  • No attic access required to install

User questions & answers

Question: What pitch does it woork for? We have an A frame
Answer: This product will work with every pitch above a 3/12. We do not recommend it below a 3/12 pitch. For a installation below a 3/12 pitch please seal the base flashing completely with roofing mastic before installation.
Question: Can this fit on a storage container
Answer: This item has a larger exhaust hole and longer flashings then the RoofBlaster. Please see link below for a better application. The RoofBlaster is also less expensive with a 17x17 flashing and an 8 inch opening. https://www.amazon.com/dp/B005I67FBS?ref=myi_title_dp
Question: Why would I pick this and not the RoofBlaster
Answer: We developed the SlantBlaster for the Texas market. The SlantBlaster is becoming popular nationwide but many vents are regional. Our RoofBlaster has been in service with great results for over eight years. Both the RoofBlaster and the SlantBlaster have the same specifications so it is a matter of personal taste in the look and color of the product on your roof. Thank you!
Question: Will this work on rv
Answer: Don’t see why not? Very quiet & well built. It would only work during the day as it is purely powered via solar power
