How to choose the right Solar Roof Ventilator

How To Choose The Right Solar Powered Vent For Your HomeSolar vents are becoming increasingly popular with homeowners. There are a number of options when it comes to choosing the right solar powered vent for your home. With all the talk about going green, a lot of people are turning to solar energy to help them reduce their energy bills. But, how do you know if the solar powered vent you are choosing will actually work for you? And, more importantly, will it work long enough to pay for itself?

There are a number of factors to consider. For example, if your roof has sarking these won’t work as well, as the roof space is essentially sealed. You can always call us at AllCoast Roofing for advice.

The energy savings come from the outside in, so there’s no need for expensive ductwork or insulation upgrades. Plus, the environmental benefits of going solar powered are huge! In fact, switching from conventional energy sources to solar power could prevent up to 1,036 pounds of CO2 emissions per year, equal to removing the carbon footprint of an average car for an entire year.

So what exactly is a solar powered vent? It’s a simple device made of weather strip that fits over the register of your central air conditioner or heater. The idea is that, when the air coming out of your registers is forced back against the weather strip, it creates a seal that prevents the conditioned air from escaping back into the room.

Whether you’re building a brand new home or you’re trying to retrofit a current home with solar power, there are several factors you’ll need to consider when selecting the “right” solar powered roof ventilator for your home.

What Is A Solar Powered Vent?

Solar powered vents are a type of exhaust fan that uses solar energy to operate. They can be used as part of your home’s ventilation system, or as standalone units that operate independently. These fans provide a constant airflow and will keep removing hot air even when the wind stops. One solar roof ventilator removes 20 times the volume of air of one standard whirlybird

How Do Solar Vents Work?

A solar powered vent allows hot air to escape a building without using electricity which lowers the temperature inside the building. There are several ways a solar powered vent can be constructed. One way is to have a fan push the hot air out through a tube that is wrapped in special foil that has the same heat-absorbing qualities as a blanket. Another type of solar powered vent uses a pump to push the air out through a tube.

It is important to think about where you are going to put it. On a roof, it should be located so that it will receive direct sunlight. The area where the vent is going to be located should not get direct sunlight at any other time. It’s also a good idea to place the vent so it is near the egress (the exit) of the building. This will help to keep the air moving and avoid creating a condition known as “draughting”. Draughts occur when there is a calm spot in the air flow. That means there is a current of still air which allows mould and mildew to grow. If you have a solar powered vent near the egress, it will help to keep the air moving which eliminates mildew and mould .


There are several benefits to using solar roof ventilators, including the fact that they are much cheaper to install than other ventilation systems. They also provide a significant energy savings. For example, a single panel will reduce your heating bill by about 10% each year. And, they are much easier to maintain than other ventilation systems.

The first step is to determine where the vents are located on your house. This is simple: just look for them! They’re almost always placed high up on the wall near the ceiling.

Once you know where the vents are, the next step is to measure the square footage of each room in your home. Divide that number by the total number of solar powered vents you choose to install. This number will tell you how many square feet of vents you should use in each room of your home. It’s a good idea to have a professional come out and measure the rooms for you so you’ll have an accurate idea of how many vents you need in each room. It’s also a good idea to have at least one extra vent than what you actually need. You can always add more vents later if you find that your house gets too hot during the summer.
