A well-ventilated roof is essential in areas that experience weather extremes. Australia often experiences long periods of extreme heat, cold or rainy weather because of its geographical location. To make their homes more comfortable, many people use air conditioning systems, fans and space heaters.
These temperature control systems address the immediate challenge to feel warmer or cooler. Yet, they don’t address the long term challenges created by poorly ventilated roofs. The accumulation of moisture or heat in your roof can cause lasting damage to your building. Poor ventilation can also reduce the efficiency of your heating or cooling systems.
This article features some of the benefits of solar-powered roof ventilation. Read on if you would like to know more about it.
Why is Roof Ventilation Necessary?
It is easy to overlook the value of the cavity between your ceiling and roof. This cavity acts as a barrier between your house and the outside environment. On hot days, your roof cavity traps the excess heat so that it does not overwhelm your living spaces. It alsocreates an extra layer of insulation to keep your home warmer on colder days.
Yet, without proper air circulation, excess heat and moisture can accumulate in your roof cavity and cause new challenges. These include
- Growth of Mould and Mildew
- Wood Rot
- Structural damage
- Pest infestation
- Water damage
How Solar Roof Ventilation Works
Roof ventilation systems can either be passive or active. Passive ventilation systems rely on air pressure differences to draw the air out of your roof cavity. Active ventilation solutions use powered systems to force air out of your roof.
In resource-rich regions, you can use wind or solar energy to power active roof ventilation systems. Wind-powered systems, such as whirlybirds, pump air out of your roof when the wind blows.
Solar-powered roof ventilation systems harness the unlimited power of the sun to operate the fans that ventilate your roof. Solar ventilation systems are active both in the winter and summer because they only need a little sunlight to generate power.
Advantages of Solar Roof Ventilation
Can Work Both Day and Night
Solar ventilation systems use highly efficient fans that have low power requirements. As such, they can work properly even on cloudy days. Most solar systems have solar battery storage systems that enable the ventilators to work day at night.
Sophisticated solar ventilation systems are fitted with thermostats and other sensors to regulate their operation. These sensors activate the ventilator when the temperate or humidity in your roof exceeds the predefined limits. With such a system, your ventilation system can run automatically even when you are away from home.
Reduced Energy Costs
The roof ventilation system runs on free solar energy. This reduces your reliance on the utility power supply. A reliable roof ventilation system also enhances the thermal efficiency of your roof. This reduces your air conditioning or heating requirements and helps you to save energy and money.
Most solar roof ventilation systems have a modular design. The solar panel and fan assembly come as a single unit. This makes it easy to install if you like DIY tasks. If you prefer to use a technician, the installation will be complete in about 30 minutes. Solar roof ventilation gives you the benefits of an active ventilation system with the peace of mind of a passive one. You never need to worry about switching the ventilators on or off. It helps you to save money while protecting your home from damage.
