Up to 50%+ More Thermal Energy
Independent testing and field applications have shown that SolarWall 2-Stage will deliver up to 50+% more energy than a conventional SolarWall system, with temperature rises over 100°F being achieved on a regular basis.

SolarWall® 2-Stage is the latest version of the SolarWall® technology and is more suited to solar space heating applications. It builds on the technological success of the original solar air heating system, generating substantial economic and environmental benefits.

SolarWall® 2-Stage has been configured to deliver a higher temperature rise – up to  36-100 °F ( 20-55 °C) above ambient temperature. It is also ideally suited for windy locations and roof-mount projects. [And as the wind speed increases, the energy output of the 2-stage system will continue to increase relative to the conventional SolarWall system.] It operates on the same premise as the original SolarWall® technology in that outside air is heated and drawn into an air cavity via tiny mirco-perforations in the SolarWall collector. With the 2-Stage system, the air is then heated a second time (which boosts the temperature rise) as it passes though a second stage of the system. The solar heated air is then directed into the building’s ventilation system - or through a dedicated SolarWall fan & ducting system - where it is distributed throughout the building.
