Are There Pros And Cons To Solar Powered Attic Fans

There are pros and cons to solar-powered attic fans. Here’s a list:

  • they work for free using the suns rays
  • they do exhaust some hot air
  • the solar fans do not require the services of an electrician to connect
  • they are also very quiet

What are the Cons?

But after seeing my solar-powered attic fan work, I have a long list of cons:

  • My fan only works when it is getting direct sunlight on the solar panel
  • If a cloud drifts through the sky blocking out the sun, the fan stops spinning immediately
  • As the sun sets, the attic is still hot and my solar fan stops spinning
  • The fan I have moves only 800 cubic feet of air per minute when the sun is shining directly on the solar panel

How Can A Solar Attic Fan Help Improve The Efficiency Of Your Homes Ac Unit

Living in Florida means lots of sunshine. When the areas of our home are not properly insulated or ventilated, heat and moisture can get trapped and then transferred into our living space. We have to bump up the thermostat to compensate for the increase in heat. A solar attic fan helps to disperse that heat and cool off our attics and thus, cool off our living space and lower our electric bills because the AC unit is not having to work as hard nor do we have to keep playing with the thermostat to find a comfortable temperature.

Attic Fan Pros And Cons

All attic fans have their pros and cons. The biggest pro to any attic fan is that it can rapidly cool the attic, so your homes HVAC system does not work so hard, and your energy costs plummet, especially during warm weather. Proper ventilation from a fan keeps your roof in shape by removing moisture from the space so the roof does not rot, and the shingles do not prematurely age by shrinking, curling, or splitting. All attic fans can stop unwanted mold growth in the space. In some cases, the attic fan might not be sufficient ventilation for the space. Attic fans require maintenance, and some units are noisy. Some types require power to function, which would cause an increase in your monthly energy bill.

Solar Attic Fans How They Work

How to Install Solar Attic Fan? (Steps &  Tips)

Solar attic fans work by pulling in the cold air from the soffits and pushing out the hot air that has accumulated at the top of the attic.

This is basically how air naturally moves: cold air is at the bottom, and warm air is at the top. The attic fan just helps the air move more which adds cooler air circulation.

Understanding The Effects Of Heat And Humidity On Your Home

With 90° plus temperatures and sticky humidity, Florida residents often escape to the inside of their homes and air-conditioned comfort. For those whose homes arent properly insulated, or have no air conditioning, what happens? Well, attics trap solar heat, which then readily transfers to living spaces, forcing those with air conditioning to adjust the thermostat down, which in turn causes utility bills to go up.

Without proper ventilation and air exchange, trapped Florida humidity can damage insulation, deteriorate your roof, cause fungal decay, and delaminate plywood. Attic ventilation in the form of a solar attic fan can help, and since it is powered by the sun, you wont use additional electricity. In result, solar attic fans remove excess heat from your home.

They Can Help You Save Money

Finally, solar powered fans can save you money. The only costs involved are the up-front purchase of the fan and anything regarding installation. Obviously, youll need to do some maintenance, as well, but those costs are pretty low.

Since you dont need electricity to power the fan, you can let them run automatically year-round, keeping your home more comfortable. That means the house will be better heated and cooled, so you dont have to spend as much on electricity bills for air conditioning and heating, which also saves you some dough.

They Can Help Save Your Roof

Attic fans can seriously help increase your roofs life-span. Moisture condensates inside the attic and gets trapped inside where damage can happen. This rot, mildew, and mold can destroy your roof years before youd typically replace it. A solar roof fan, however, sucks much of that moisture out and adds the much-needed ventilation that prevents these build-ups.

Ventilation for your roof and attic can also help prevent ice damming that destroys the eaves of the roof.

Reduced Attic Temperatures Energy Savings And A Cooler Home

There are lots of before and after tests that prove the effectiveness of solar attic fan systems in lowering attic air temperatures. A cooler attic cools your homes ceilings and reduces the burden on your air conditioning system, saving you money. This is the principal reason for installing solar attic fans.

How Does A Solar Attic Fan Work

4 Best Solar Attic Fans On Costco

Just like every other solar powered device out there, a solar attic fan operates by collecting energy from the sun through the use of solar cells or photovoltaic panels. These panels absorb the suns energy, and the said energy is then converted into electricity, which powers up the fan. Simple, right?

It works like this as the panels continuously collect solar energy to turn the fan on, the fan starts to rotate and pushes warm air out of the attic and exchanges it for cooler air from the outside. This process is extremely helpful during colder and warmer months. In summer when the heat can be unbearable, an air conditioner can become overworked as it tries to counteract the sweltering temperature.

In winter, moisture tends to set in and build up as the cold air outdoors meets the warmer temperature indoors. The issue with moisture is that it causes mold and mildew that can damage your home over time. But with the proper ventilation that an attic fan can provide, all these problems can be prevented by exchanging warm for cold air or vice versa whenever it is necessary.

Consider Size And Weight

A bigger fan, with a larger coverage area, will almost always be larger and heavier, although this also depends on the design materials for example, the small 1,280 CFM fan from Brightwatts weighs 28 pounds compared to the 34.5-pound 1,750 CFM fan from GBGS. Size can be important if you have limited space in your attic or a small entryway, since you need to be able to get the unassembled fan into the attic and have the blades rotate without obstructions.

A roof turbine costs $100 to $150 installed. Usually, you will have a roof turbine installed at the time you have your home re-roofed. Many homeowners opt to have old turbines replaced when they fail to spin. A roof turbine does not require electricity to function and depends on the hot air pushing up to spin. The wind turbine exhaust has been used for centuries. It is highly energy-efficient. However, during severe storms, it can allow rain to enter the attic space. It cannot be controlled with a thermostat.

Solar Powered Attic Fans FAQ
1. Heat Builds Inside An improperly Vented Attic

The sun beats down on a homes roof and heats up the enclosed attic space. Passive vents allow some circulation but do not provide the pressure needed to force out the hot air.

2. Solar Attic Fan Provides Air Circulation

The photovoltaic panel of the solar attic fan collects sunlight that powers the fans motor to increase air movement.

3. Air Circulation Moves Hot Air Out Of Attic Space

The increased air circulation provides the pressure needed to force out the hot air from your attic. Attic venting can cool your attic space by up to 40 degrees!

Attic Venting Key Concepts

Attic ventilation is an important aspect of maintaining the structure of your home as well as saving energy. Improper attic venting can lead to moisture buildup that can cause mold growth and also cause wood rot. The key to proper attic ventilation is to create continuous air circulation throughout the attic space while preventing moisture from entering. In an ideal venting system, air should enter the attic from the eaves or soffits and escape outside at the roofs ridge.

Evaluate Your Attics Ventilation

Any solar attic fan that you choose to install has one goal: to take the hot air out of your attic. So, what replaces this hot air then? Most lofts will feature ventilation points typically located at the eaves of your roof. Look for this in the bottom corner of the roof. Make sure your attic has the proper ventilation to take in cool air after the hot air has been transferred outward.
