SVPro SolarVenti solar air collectors
All SVPro solutions are based on the award winning SolarVenti solar air collectors, designed and built in Denmark. SolarVenti has European Keymark and DIN Certo certifications, with test performance verification from the Fraunhofer test laboratories in Germany.
The Solar Air Collector is heated by the solar radiation when the sun shines, there is also ambient heat and good drying on overcast days. The energy, heat and drying converted by the black filtration mat via the solar radiation will be transferred into the building as fresh, low humidity, preheated air. The air enters the collector through a patented perforated rear wall into a plenum. The air then passes through the absorber filter, made of a black technical material, which is resistant to high temperatures. The material is also the effective air filter.
Solar collectors are individual modules of approximately 2m2

A SolarVenti collector is a flat-panel unit mounted on a roof or wall. Sunlight heats air inside the panel, and a solar-powered fan draws outside air through the panel and into the building. The heated, dry air is delivered directly to the space — no batteries, no grid power needed.
In Australian conditions, the delivered air is typically 20–40 °C warmer than outside air, depending on solar intensity and airflow rate.
See the performance datasheets in the Downloads section for model-specific flow curves.
The panel has no moving parts except the fan. The PV cell and fan motor carry manufacturer warranties — confirm current warranty terms with SVPro.
The actual figure depends on collector count, building volume, and supplementary ducted fans.
Solar intensity in southern Australia is lower in winter but the system still delivers heated air on sunny days. Overcast periods slow drying but do not reverse it.
The system is passive during darkness and very low sunlight. Buildings retain heat and lower humidity from daytime operation. A controller can close dampers at night to prevent cold air back-draught.
Performance graphs for Australian capital cities are included in the performance datasheets.
