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 several 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 work you? And, more importantly, will it work long enough to pay for itself?

If your roof has sarking these won’t work as well, as the roof space is 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.

Whether you’re building a brand-new home or retrofitting a 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?

A solar powered vent on a roof is a solar powered fan that is installed onto a building’s roof or gable to cool a building’s attic space down during hot days. The mechanical fan is powered by either a mounted solar panel or a solar panel connected to the fan via cables1. These vents can reduce roof temperatures by up to 30°C and room temperatures by up to 6°C2. They are cost-effective and energy-efficient solutions to your home’s ventilation problems3. 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 twenty times the volume of air of one standard whirlybird

Solar Roof Ventilation and how it works

A solar roof ventilation allows warm 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 clever 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.

Benefits of Solar Vents

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.

  • They make your home more energy efficient
  • Keeps air circulating to keep your home cooler
  • Improves energy efficiency
  • Reduces air conditioning costs
  • Can be used year-round
  • Saves money on heating and cooling costs

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. Have a professional come out and measure the rooms for you so you’ll have an accurate idea of how many vents you need. It’s also a good idea to have at least one extra vent than what you need. You can always add more vents later if you find that your house gets too hot during the summer.

You can find out which vent is right for you by calling 1300 766 337 or visit our solar roof vents page.

Wayne and his expert roofing team are the ideal trades team. From the initial call for a quote to the follow up after the job was complete Wayne and AllCoast roofing were a delight to deal with. The quote was not the cheapest or the most expensive but the finished product I have no doubt is the best possible. Our roof was checked over, an accurate assessment made, and value-for money quote provided. Then the very thorough cleaning, repointing and renovation work, and finally painting were all carried out by their respective tradesmen in a thorough and professional way. After dealing with a few other trades for other services I can honestly say AllCoast roofing is the best in the business! Thank you Wayne and team, I love my updated roof!
