Glass Roof Tiles Collect Energy

With a roof made from these tiles, it is possible to produce 300-500 kWh per square meter per year (28-46 kWh per square foot per year). Heated air collects under the glass tiles like a greenhouse, and is then drawn in and concentrated to transfer the heat to a hot fluid for use in heating the building. The system is ideal for use with a heat pump or a boiler where a hot water storage tank stores the collected heat. Then, when heat is needed, the heat pump or boiler has pre-heated water available, so that less external energy is needed to heat the space.
