Solar photovoltaics are, depending on the day, between 8-15% efficient meaning much of the sun's energy's is lost as heat. While solar thermal systems offer a way to harvest this heat energy for heating water or interior spaces, this option has usually displaced the electricity generating PV on rooftops. A new system from SolarWall, the SolarDuct PV/T, offers a combination of solar photovoltaic and solar thermal in one assembly providing a means to heat and power from the sun with one product.
The system is an evolution of the SolarWall system, a vertical mounted solar thermal and heat recapture system that transfers heat into or away from a building's HVAC mechanicals depending on the season. The SolarDuct PV/T is based on the same principle of capturing heat from the sun and heat generated from excessive solar gain on buildings. The new system adds photovoltaic over thermal ducts to maximize energy efficiency.
