11 best solar powered roof fans

Solar-powered roof fans, also known as solar attic fans or solar roof vents, are devices designed to ventilate and cool the attic space of a building using solar energy.These fans are related to solar panels and renewable energy solutions. Here are some key points about solar-powered roof fans:

  1. Energy Source: Solar roof fans are equipped with photovoltaic (PV) solar panels that capture sunlight and convert it into electricity. This electricity powers the fan motor, eliminating the need for grid electricity or batteries.

  2. Ventilation Benefits: Solar roof fans help regulate the temperature in the attic by expelling hot air and moisture. During hot weather, they can significantly reduce attic temperatures, which can help lower cooling costs and prevent heat-related damage to the roof and structural components.

  3. Energy Efficiency: By reducing the heat load in the attic, solar roof fans can improve the overall energy efficiency of a building. They work to prevent heat from radiating down into the living spaces below, reducing the load on the HVAC system.

  4. Installation: Solar roof fans are typically mounted on the roof, often near the peak, to facilitate the removal of hot air. They require proper attic intake vents (such as soffit or gable vents) to allow fresh air to enter the attic and create a continuous airflow.

  5. Maintenance: Solar roof fans are generally low-maintenance. The solar panels may require occasional cleaning to ensure optimal energy production. Otherwise, they do not have moving parts that frequently wear out.

  6. Quiet Operation: Solar-powered roof fans operate quietly and do not create disruptive noise inside the home.

  7. Environmental Benefits: These fans are environmentally friendly because they reduce the need for electricity from the grid, which can help lower carbon emissions. Additionally, they can improve indoor air quality by preventing mold and mildew growth in the attic.

  8. Cost Savings: Solar roof fans can lead to energy savings by reducing the workload on air conditioning systems. Over time, these savings can offset the initial cost of installation.

  9. Sizing: Proper sizing of a solar roof fan is crucial to ensure effective attic ventilation. Factors such as attic size, climate, and roof pitch should be considered when selecting a fan.

  10. Warranty: Many solar roof fan manufacturers offer warranties on their products, which can provide peace of mind and protection against potential issues.

In summary, solar-powered roof fans are a sustainable and energy-efficient way to improve attic ventilation, enhance energy savings, and extend the life of roofing materials. They are a valuable addition to homes and buildings, particularly in regions with hot climates where attic temperature control is essential for comfort and energy efficiency.

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.

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.

Does it have a turn off switch so I can switch it off during the winter months?

There is no need to ever turn these fans off because you want air movement as much as possible throughout the day ALL YEAR LONG. During the winter months, you want to protect your insulation’s R-Value (its loftiness) as much as possible. Proper ventilation, especially during the winter months where condensation will form on the underside of your roof deck, is very critical as well.

Just remember, the ideal temperature inside your attic is the same ambient temperature as outside your home. If your attic space is the same temperature as the outside, no condensation will form. That’s why a soda can doesn’t form condensation when it is inside your fridge. It’s when you bring it out and there is a difference in temperature that the soda can starts to sweat. Proper ventilation in your attic space will help mitigate condensation from forming in your attic and it will help keep your insulation’s loftiness and effectiveness at its highest performance.

Does it have a thermostat?

There is absolutely no reason to add a thermostat to our vent fans. You want them working any time the sun hits the solar panel! Remember, you want the temperature inside your attic to match the outside temperature. So your vents need to be working 24/7.

Why are metal vents better?

As you read above, your roof can get upward of 190 degrees on the surface. Metal vents will last a lifetime on a roof. The same cannot be said about plastic vents. As a roofer, it is never surprising when we see cracked and brittle plastic vents on a roof. We have always used metal vents on all of our roofing jobs. So when Solar Blaster was born, there was no question about using the same metal vents we’d been installing on roofs for over a quarter century as the basis for our solar solution.

What size is the fan?

The fan itself is NOT large (we have the specs listed on this page). Most of our vents have 50 square inches of open venting. Our fans are intentionally small so they do NOT cover much space inside the vent’s shaft as we still need these hybrid passive vents to do their job when the sun isn’t shining.

Features

  • Solar-powered fan vent that ventilates a home's attic, shed or garage
  • Helps remove hot, moist air faster than a passive vent alone
  • Helps promotes uniform air movement throughout the vented space
  • Helps minimize mold/mildew growth
  • Helps prevent moist wood that can lead to rot and pest infestations
  • Improves your living space by removing the hot, oven-like temperatures in a home's attic
  • Makes a shed or garage into a cooler work environment
  • Improves the air quality in sheds and other work spaces by promoting fresh air movement
  • Prevents tools from rusting in sheds and garages because moist air is being removed
  • Easily installation (install it just like any other roof vent)

More Features

  • 50,000 hour-rated fan (15 years at 9 hrs/day)
  • 2700 rpm/39 cfm two-ball bearing fan
  • 17" base flashing allowing for better weatherproofing for leak-proof installation
  • ⅛" mesh screen — pest-free

How many vents does my home need?

There a lot of roof vent calculators out there on the web (including our website) where you can plug in your attic volume to calculate the proper number of vents. Most building codes and shingle manufacturers also list their requirements. For simplicity sake, we recommend one of our vents every 6-8 feet along your ridge (with enough intake vents as well — they are a crucial part of this system of ventilation).

Aside from Attics Where Else Can These Vents be Used?

Sheds and Garages:

  • Stop working in unbearable conditions when you can have fresh air circulating in your shed or garage whenever the sun is shining. Plus, keep those gas fumes from smelling up your utility shed.
  • Take a proactive approach to improving your garden shed's ventilation. It is an easy installation.
  • Sheds and garages should not be saunas. Let us help you convert it back to a workable space.

Containers:

  • Because of the metal flashing that is moldable around the metal curves of a container's roof, it is possible to install our vents on containers.

Why choose Solar Blaster Fans?

Solar Blaster Fans was created by a professional roofer who saw a huge problem in his industry so he designed a hybrid solution to solve that issue — a solution that not only works within the confines of current building codes but improves on their effectiveness in a green and environmentally-sound way.

Are they warrantied & for how long?

Our vents are warrantied for 5 years. The way our vents are designed, it makes it very easy to swap out parts if anything goes wrong.

User questions & answers

Question: Are the solar panels tiltable or is the panel fixed ? I have a sloped roof
Answer: Don’t know for sure, but Idoubt it.
Question: How easy is this to install
Answer: I ordered the purple ink and mine do not have a Japanese label on them and only English writing. I have them in every color and tip size. They are my favorite pens, even the needle tip .5. I normally like the .7 tip.
Question: what does lifetime limited warranty mean for this product
Answer: Yes it is the entire box which consists of 12 tubes
Question: Can the fan be mounted on the side of a structure instead of on top
Answer: Follow-up to my previous post suggesting that people file a claim based on not receiving the "entire order" (12 tubes, as advertised): Within hours of my claim request (as stated in previous post), I received an e-mail from the seller that said: "Unfortunately, we have been merged with another listing with the incorrect information. Our listing is intended for a single tube. We have went ahead and issued a full refund for your order. Item is not required to be returned." The only thing I can say is, "the squeaky wheel gets the grease"!! Good luck! Here is the Amazon link to the item & particular seller that I am referring to: http://www.amazon.com/Pentel-Super-Hi-Polymer-Refills-C505-HB/dp/B001HA5SYK/ref=sr_1_3?ie=UTF8&qid=1445624064&sr=8-3&keywords=Pentel+Super+Hi-Polymer+Lead+Refills%2C+0.5mm%2C+HB%2C+Black%2C+12+Tubes+with+12+Leads+per+Tube+%28C505-HB%29
