How much do you know about solar ventilation? The typical person, outside of tradespeople, doesn’t know as much as they should. That’s the job of your local handyperson, so whatever they recommend to their customers, they will likely not question it unless a second expert comes in. Cooling your home needs to be efficient, effective and should be cost-effective in the long run – and not all solutions are created equal.
How Ventilation Really Works
At its most basic, ventilation works by trying to extract all the hot air from say your roof space and pushing it out of your home. It will then replace this heated air with cooler ambient air. Since cold air stays low and hot air rises, this effectively reduce overall heat and regulates moisture that amplifies the “hot” feeling.
Vent systems are divided into two types, depending on the way they do work: active and passive ventilation.
Passive Ventilation Systems and Why They’re Ineffective
Passive ventilation does not use electricity, typically stationary or relying on external sources to make it work. Among these well-known passive systems is the whirlybird – an aluminium dome on top of roofs that is popular regardless of their inefficiencies due to its cheap design.
The idea of a whirlybird is that it contains fan blades that rotate in the presence of active winds or hot air. When either are available, it starts spinning, sucking out hot air.
Typically, whirlybirds can take out 100 m3/h of air with a 12km/h breeze – a little on the low side considering small sized homes require 900 m3/h of hot air removal and larger homes need 2100 m3/h of hot air removal. This means you would need at least 9 (small) and 21 (large) of these whirlybirds to get them to be nominally effective.
There’s also the fact that the flawed concept of needing hot air to remove hot air is not only bad – it’s outdated and uninspired. You need to stop the heat from accumulating in the first place!
Active Vents: One Step To Remove Hot Air
Active ventilation systems typically require electricity to work. They work similar to more effective exhaust fans, that exhaust all of the hot air. This, however, is not that practical.
HVAC – heating, ventilation and air-conditioning, accounts for 46% of expenses for homes and businesses. Why would you add power hogs to your system that can up your costs in the long and short run?
Solar Ventilation and the Perfect Ventilation System You Need
Solar ventilation is the perfect hybrid of the effective cooling of active systems with the cost-effectiveness of passive systems. There’s no other product in the market that does it better than Solar Whiz.
What Solar Whiz brings to the table is unparalleled cooling. With an industrial grade fan system powered by harnessing the light of the sun, you get heat suction without the operational costs that you will incur with a plugged-in system. Zero operational costs, better overall cooling, more savings for you.
Our vent system can remove as much as 900 m3/h up to 2100 m3/h depending on the model for residential cooling. For commercial applications, we offer 7,000 m3/h and 10,000 m3/h of suction air flow, able to help air-conditioning perform better, by up to 20%. One Solar Whiz trumps up to 9 equivalent whirlybirds without costing you more in the long run.
Solar Whiz Day to Night Cooling
Our system makes sure that from dusk to dawn, no hot, moist air builds up in your roof space and home. If there’s no heat in the first place, that means there’s less heat being transferred into your home.
Solar Whiz runs with a photovoltaic panel to power it up, but if you need its services even after dark, our night operations modules are just what you need for Solar Whiz to give you excellent ventilation from day to night.
Efficient. Effective. Saves money and energy. Solar Whiz is all you will ever need in roof vents.
