What Is A Solar Attic Fan And Who This Is For?

Solar attic fans are ideal for extracting the warm air from the attic and infiltrating cool air from outside inside the attic. Overall, a solar attic fan keeps the insides of a house cooler thus reducing the need to turn on the air conditioner every now and then.

As the name suggests, solar attic fans run on solar energy which is of course cost-efficient. 

Solar attic fans are ideal for those who have an attic at home and are looking for a cost-effective way to reduce the electricity bill. A solar attic fan ensures room comfort and improves the ventilation within the room thereby keeping them cool. 

 

How Does Solar Attic Fan Work?

Installing a solar-powered attic fan on the roof of your home can bring you a world of benefits. The unit operates all throughout the day powered by the energy of the sun. The primary function of the unit is to extract the warm air from the attic. 

If you don’t know. during hot summer days, the temperature in the attic can go up to 160 degrees Fahrenheit or more. An attic fan absorbs this air and expels it outside, thereby making your attic space reach a temperature similar to the outside. 

There are static soft lift vents installed in the fan which absorbs the air. With the help of the fan, a continuous movement of hot air moving out and cool air moving in is established. 

During the winter, however, the moist air from within the house rises and settles on the underside of the roof. The attic fans stop the moist air from condensing on the underside and thus keeps the attic cooler and drier. Overall a solar attic fan not only results in a pleasant living space but also provides protection to the roof. 

Advantages And Disadvantages Of Solar Attic Fans:

Though solar attic fans run on eco-friendly energy, it has both pros and cons. 

Advantages

Runs On Solar Energy:

Since these fans run on solar energy they do not cost a lot. That means one does not require to use electricity from home or office to run these fans. Not only does it save up on electricity costs, but these fans are also great for the environment. 

Less Expensive Than Full Ventilation Setup:

Solar attic fans are usually quite less expensive than a full ventilation setup. These fans require less time and have a less invasive installing procedure than most other systems. 

Creates a Cooler Attic:

This is the primary reason to install a solar attic fan in the first place! They result in a cooler attic which in turn cools down the home too. That means, the air condition need not run for a long te during the summer months. Additionally, these fans also keep the attic free from dust and dirt. 

Improved Curb Appeal:

Solar attic fans can enhance the appearance of your home while being environment friendly. Additionally, it provides a profile lower than the other ventilation system available in the market. 

The solar attic fans are mostly sleek and do not take a lot of space, unlike other units that are bulky and damage the look of the house.  A solar attic fan does not require any roofing cement, caulk, or other things to prevent leaking. All one needs to do is cut one or two holes on the roof in case they are purchasing multiple fans and finally the third hole if remote panel location is required. 

 

Disadvantages:

 

Cost Consideration:

Though there are multiple benefits of a solar attic fan, it requires a great capital cost than most traditional ventilation setup. 

Of course, the initial investments can be recovered with the energy cost-saving, not many people are ready to spend so much initially, which functions as a barrier. A single solar attic fan can cost up to $ 600 or above. Additionally, $150 to $300 needs to be spent on installation. 

In some areas, a building permit may also be required for the installation of this unit. 

Sunlight Required:

Sun-powered attic fans are risky since they require the energy of the sun to operate. This makes it ideal for people living in tropical areas to install a solar attic fan. However, this might not be a wise choice for those living in areas where the sun rays are not that strong. 

Can Lack Power:

When compared to a motor-powered attic fan, the solar ones do lack power. These fans are capable of pushing out more air compared to solar attic fans. 

More Solar Attic Fan Units Required:

As mentioned earlier, solar attic fans cannot move too much air as they work on lower power output.  This means one needs to spend double on a solar attic fan. For instance, if one has a home that is 1600 square feet in size, it may require three fans to get the desired output. 

 

Benefits of solar-powered attic fans:

As mentioned earlier, there are quite a few benefits of having a solar-powered attic fan installed on the attic. Let’s look at a few benefits:

Reduced HVAC Costs: 

Proper ventilation for the attic means continuous air circulation within the attic while preventing any form of moisture buildup. In an ideal situation, air should never enter the attic from the thin cracks and the eaves or leave the same through roof ridges. 

During the summer months, the stagnant air in the attic gets heated due to heat on the roof. Though building codes require all houses to have a passive vent system, the passive ventilation does not provide the required amount of pressure required to push the air outside the attic.

This can only be achieved by installing a solar attic fan at the ridge of the roof which will pull the air from outside inside the room.  As the heat is reduced the requirement for you to keep your air conditioner continuously turned on is also not required anymore. 

Similarly, in the colder months, since the moist air is extracted from the attic, the furnace can produce more heat which will last longer. 

Solar Energy and Cost Efficiency:

A solar attic fan is the most simple way to provide a mechanical venting system to your home. Solar attic fans need no structural changes or new wiring. 

As with most solar gadgets, when the solar panels on the attic fans heat up they transform that light to energy. For this, solar panels need to be mounted in an elevation. 

Raising the panels reduces any form of heat buildup and thus provides enhanced circulation of air in the attic. The brackets used for mounting the solar panels increase air circulation and results in better performance. 

Tax Saving:

Not only to keep your home cool and comfortable, but solar attic fans also save you money. If you file your taxes online the Federal Tax credit for attic fans has been extended to 2021

If you have a solar attic fan installed in your home, it is entitled to get 30 percent, which is nearly $1500 credit on the purchase of the fan along with installation and sales tax. 

Roof Protection:

Do you know, excessive heat can damage your roof? Too much heat build-up can damage the asphalt shingles. 

During the winter days, the attic is the place where the moisture-laden air condenses. This can be very damaging and is the primary reason for the growth of mold, mildew, and rot. Even metal objects left in the attic rust to a great extent during winter. A solar attic fan can save you from all these issues by maintaining smooth and continuous air circulation. 

Noiseless:

Most people dislike fans for the noise they create. If you are not installing an attic fan for this reason, then you don’t need to worry! Solar-powered attic fans are very quiet, especially at night. In fact, they don’t even work at night!

 

Things to Consider Before Buying Solar Attic Fans:

Solar attic fans can bring you a world of benefits along with a cooler home. However, to get all those benefits, you will first have to buy an ideal attic fan. 

To that end, here are a few things that you need to consider while purchasing your solar attic fan:

Mounting:

Solar attic fans can be mounted both on the roof of the home or the gable. Most people prefer the latter as it looks better mad clean from the outside. 

This is ideal for those who are scared of height or going to the roof. 

Capacity:

The actual size of the attic must be taken into consideration before buying a fan for the same. Additionally, while buying the fan, check out the size of the room it can comfortably cool down. 

Generally, it reads something like ” cools down a 1500 square feet” or so. But before that find out the size of your actual attic. This can be done easily by multiplying the length by the breadth and you will know the size of the attic. 

Wiring:

One can easily get an electrician to hardwire these units to the primary electrical supply of the house. 

Or these can be inserted into a socket if there are any in the attic. People who are extremely environment cautious can even use solar panels to power up these units. 

Since attic fans are made out of metal, they must be fitted properly. To that end, it’s highly advisable to get an electrician to install the unit or at least consult one for the process.  Finally, the fans must be grounded in case there is lightning. 

Space:

Though many attic fans are small and easy to carry, others can be as heavy as an HVAC  setup. However, most manufacturers state the required square footage for a give make or model. 

Material Concern: 

Since most attic fans are placed near the rood or outdoors, the material used in the making must be weather resistant. To that end before buying a unit check the material used in the construction. 

Make sure the unit is made out of rust and corrosion-free stainless steel or high-quality plastic. 

Thermostat Adjustability:

It’s advisable to get a unit with an adjustable thermostat. This way the user can set the desired temperature for the fan and forget about the same. The fan will work towards the set temperature range. 

As the weather and temperature changes, a new setting can be established quickly. Attic fans can either have an on/off button or can use a thermostat that automatically kicks in the temperature it was set at. 

The second option is always the better choice. 

Local Weather Conditions:

Before buying a solar attic fan consider the climate in the area you live in.  Is there constant rain? Are there occasional snowstorms and strong winds? In that case, make sure you get a weatherproof solar attic fan that is suited for the weather conditions of your area. 

 

How to Maintain Solar Attic Fans?

Once the solar attic fans are installed, your work is far from being done. In fact, now begins your work. 

You have to ensure that the fans last for a long time and for that proper care of the fans must be taken. 

Here are five tips to maintain solar attic fans:

1. Keep The Roof Free Of Debris

If the roof is not cleaned for a long time, then branches, leaves, and twigs accumulate on the terrace. Keeping your roof clean will not only maintain the quality of your roof but also keep your solar fan protected. 

If branches and twigs get stuck in the fan blades it can cause mechanical failure. Branches and twigs can also scratch or crack the solar unit permanently. Thus periodic cleaning of the roof must be done. 

2. Use A Towel To Clean The Solar Panels

Solar fans run on power generated by the solar panels. To maintain maximum power generation, the panel needs to be cleaned regularly. If dust and pollen gains accumulate on the panel, it will not be able to absorb the maximum energy of the sun. 

Thankfully, cleaning the solar panel is very easy. All you need is a damp cloth to gently wipe the surface of the solar panel. How often should you clean your solar panel depends on where you stay. If it’s a dry and sandy area, cleaning frequently may be required. 

3. Keep Your Solar Panels Positioned Properly

For the solar fans to operate to its optimum level, the solar panels must be in a direct line with the sunlight. To that end, all branches and twigs must be trimmed and cleaned so that they don’t block the light. 

4. Check The Panels For Damage

While cleaning the debris off the roof, check if your solar panels have suffered any form of damage. These can be scratches, chips, or cracks. These defects might hamper the efficiency of the solar panels which in turn will negatively impact the performance of the attic fans. In case there are any damages, get it fixed right away. 

5. Check For Damages Created By Rodents

Attics, garages, and other stuffy places are heaven for the rodents. If your attic too has one then you have to first chase it away. Additionally, check the panels to see if there are any chewed wires or fan blades. Chewed wires not only can shut down the unit completely but is also a great fire hazard. Any form of damage to the fan blades will impact the performance of the fan. 

So check your unit frequently
