Best Solar Attic Fan FAQ’s

Still confused about the best solar attic fan? Don't worry - we have all the answers you need here! Get ready to make your next purchase with complete confidence, as we cover all Frequently Asked Questions about these great energy-efficient options.

What to look for when buying a solar attic fan?

When shopping for a solar attic fan, it is important to look for models that have low wattage motors and high-efficiency blades.

Additionally, check the fan's durability rating and warranty coverage.

Lastly, make sure the design of the fan fits your needs in terms of size, capacity and type of venting necessary.

Are solar attic fans a good idea?

Yes, solar attic fans are a good idea.

They can help reduce the temperature in your loft or attic area and make it more comfortable to spend time in.

Additionally, they can also reduce energy costs as they take advantage of free energy from the sun to circulate air through your home.

Finally, installing solar attic fans is cost-effective and does not require any maintenance once installed.

Do solar attic fans run all the time?

No, solar attic fans will typically only run when the sun is shining onto the solar panel.

There are some options that have AC backup options that can bring in cool air while the sun isn't shining.

Where is the best location for a solar attic fan?

Most people prefer roof mounted attic fans, because the hot air rises and more will escape through the roof mounted attic fan.

If you have a roof that you either can't or don't want to cut a hole in, there are gable solar attic fans that might be a good option for you.

For improved performance and energy savings, make sure your solar attic fan has access to at least six hours of direct sunlight each day.

Do solar attic fans work in winter?

Yes, solar attic fans can work in the winter.

They are designed to pull hot air out of your attic and exhaust it outside, which keeps the temperature inside your attic comfortable no matter what season it is.

To maximize the efficiency of a solar attic fan during winter months, make sure you add insulation to your roof and ensure that there are no obstructions blocking incoming sunlight.

This will help keep temperatures warmer in your attic during cold weather.

How much does a solar attic fan reduce temperature?

A solar attic fan is designed to reduce the temperature of your attic or other areas of your home.

This type of fan typically reduces the temperature by 20-30 degrees Fahrenheit and helps keep hot air from entering the living area.

Additionally, it can help with humidity control in hot climates, making it a great solution for improving comfort levels in any season.

Do solar attic fans run at night?

No, solar attic fans don't run at night since they rely on the sun's energy to work.

At night when the sun is no longer available, the fan will be inactive and won't provide ventilation or cooling.

An alternative solution for providing attic cooling during the night is to install an electric powered attic fan that runs on electricity from your home's power grid.

What wattage solar attic fan do I need?

The wattage of the solar attic fan you will need depends on the size and layout of your attic.

Generally, a 20-watt fan is sufficient for attics of up to 1,200 square feet in size.

To be sure that you get proper ventilation, it is best to consult with an experienced professional who can provide recommendations based on the dimensions and insulation levels of your home.

Why did my solar attic fan stop working?

This could be caused by a number of factors.

The most common are low power supply, malfunctioning controls or fan motor, or clogged blades that prevent the fan from spinning correctly.

It's important to contact a professional to diagnose and fix the issue as soon as possible in order to prevent further damage and keep your attic properly ventilated.

Are solar attic fans noisy?

Solar powered attic fans are generally very quiet, as they only require a small amount of energy to operate.

These fans create minimal sound and the noise produced is typically just a light hum from the motor.

Furthermore, most solar power attic fan models come with an adjustable speed setting that allows for further noise reduction if desired.

How long does solar fan last?

A solar powered attic fan typically lasts between 10-15 years depending on usage and maintenance.

It is important to keep the fan’s components clean, as dust buildup can reduce its efficiency and lifespan.

To maximize the life of your solar fan it is recommended to inspect the components yearly and clean them as necessary.

What voltage is a solar attic fan?

A solar attic fan typically runs on 12 volts of direct current (DC).

The amount of power generated by the fan depends on the size, design and quality of the photovoltaic cells used in the system.

In general, this type of fan will produce about 120 to 130 watts per hour under ideal weather conditions.

Do solar attic fans have battery backup?

Most solar attic fans are not equipped with battery backup systems, though some models do have an AC backup option.

This allows users to regulate their internal home temperatures even when there is not enough direct sunlight for the fan to generate its own electricity.

Solar attic fans are an excellent way to maximize energy efficiency and reduce air conditioning bills without sacrificing comfort levels.

What temp should attic fan be set at in summer?

The best temperature to set your attic fan at during the summer months is between 105°F and 110°F.

Setting the temperature too low may reduce the efficiency of the fan, while setting it too high could cause damage to nearby components.

For best results, check with a licensed HVAC technician for advice on what temperature to set your attic fan at for optimal cooling in summer.

What circuit should an attic fan be on?

An attic fan should be on its own dedicated circuit, to prevent it from overwhelming the other electrical components.

This dedicated line should also have its own breaker switch or a fused disconnect connected to avoid damage or injury during use.

It's recommended to consult an electrician if you're unsure about how and where to install the fan circuit safely and correctly.

What size solar fan do I need?

The size of solar fan you need depends on the square footage of the area to be ventilated.

Generally, for every 500 square feet of attic space, you should select a fan with at least 900 CFM (Cubic Feet per Minute) capacity.

To ensure maximum efficiency, it is recommended that you consult a certified HVAC professional who can help guide you in selecting a properly sized solar fan for your needs.

Can solar panel directly run a fan?

No, solar panels cannot directly run a fan. Solar panels generate DC electricity and fans require AC current for proper operation.

To convert the DC power generated by the panel into AC power suitable for running a fan, you will need certain additional electric components like an inverter or charge controllers.

Inverters are used to turn direct current (DC) from solar energy systems in to alternating current (AC).

The AC can then be used to run most household appliances, including fans.

Do solar attic fans work on cloudy days?

Yes, solar attic fans still work on cloudy days as they draw energy from the sun’s UV rays.

Solar attic fans are designed to operate with low levels of sunlight, meaning that even under cloudy conditions electric current can heat and power the fan motor.

The most efficient solar attic fan models will still provide some cooling benefits on a cloudy day but may not be as effective compared to sunny weather.
