Keep Your Home Comfortable With A Solar Roof Fan

Solar roof fans, also called PV fans, work similarly to other types of attic fans. They help remove hot air from your attic and replace it with cooler air, reducing the workload of your HVAC system in keeping your home comfortable in terms of temperature.

Solar roof fans are different because they use solar power instead of regular fossil-fuel energy sources. By utilizing the sun's natural energy, you reduce your home's carbon footprint and save money compared to a conventionally powered attic fan. A conventionally powered fan consumes the same amount of energy as an HVAC system. So, solar roof fans are a win-win!

If you have an attic, chances are it's a good fit for installing a solar roof fan. You don't need much extra space compared to a gable or roof-mounted attic fan. Just like any solar panel, ensure the mechanism gets plenty of sunlight to generate the power it needs. Luckily, most solar roof fans can be adjusted to capture as much sunlight as possible. Plus, on sunny days when the attic gets hot, these fans use the sun's energy to stay cool anyway!

A solar roof fan is an excellent option for homeowners with limited electrical capacity in their attic or those who prefer to avoid dealing with the wiring and connections of an electric-powered attic fan.

How a Solar Roof Fan Will Benefit Your Home

More energy-efficient. A solar-powered attic fan uses the sun’s energy rather than the fossil fuel used for electrical power in many homes. The lack of harmful emissions helps your home reduce its carbon footprint.

Super-quiet. Like many solar-powered components, a solar roof fan collects energy without generating excessive noise pollution. The only sound will come from the rotating fan blades, not electrical components.

Cools the attic and controls humidity. A solar roof fan works as effectively as its electrical counterparts to moderate attic temperature and prevent moisture buildup.

Protects your roof.  Excessive attic heat or condensation can cause roof shingles to warp, melt, or encourage mold or mildew growth. A solar roof fan keeps ventilation active and controls humidity to keep your roof from enduring those problems.

Extends the life and energy usage of your HVAC unit. All attic fans are designed to relieve some of the pressure from a home’s HVAC system. But solar roof fans do so without any fossil-fuel consumption. You can extend the life of your HVAC system while reducing your carbon footprint.

More cost-effective. In addition to the moderate cost savings from using less electric power, installing a solar roof fan can generate more savings in the form of federal tax credits for using renewable energy.

How do solar attic fans work?

Roof solar fans work by taking the heat that is radiated onto a rooftop and transferring it away from the home, creating an air flow. This air flow is created by using energy from the sun, which is absorbed by solar panels on the roof's surface. These solar panels convert the sun’s energy into electricity, which powers a fan attached to them. The fan then pulls in cooler air from outside and pushes out heated air from inside. These fans are becoming increasingly popular due to their ability to reduce energy costs since they do not use any energy other than that of the sun. They also provide increased ventilation and help remove excess moisture from a room or attic, promoting overall better indoor air quality.

Solar roof fans are typically placed on flat roofs with south-facing exposure to receive maximum sunlight throughout the day. This exposure ensures they can capture as much of the sun’s energy as possible for optimal operation. The solar panel collects direct radiation from the sun and converts it into electricity which then passes through a controller board and powers up an electric motor that drives the fan blades. As long as adequate sunlight is available, these fans will run continuously without drawing additional power from your home’s energy supply.

These fans require very little maintenance as they have no moving parts other than their internal components, meaning they don’t need to be lubricated or cleaned regularly like traditional exhaust systems do. Solar roof fans also require fewer wiring connections than regular electric exhaust systems; this helps cut down their installation time significantly while ensuring safety for those who install them. These types of systems are also more environmentally friendly since they contribute zero pollution when running on solar power alone.
