A device that collects solar energy, concentrates it, and converts it to useful forms of energy. Typical systems are based on heat‐absorbing (usually black) panels containing pipes through which air or water is circulated, either by thermal convection or by a pump. The air or water is heated as it passes through the panel, and the heat is usually circulated around a building through pipes. Such collectors require a lot of sunshine to work efficiently, and are not really suited to high latitudes. The energy produced is relatively expensive because of the high capital cost of installing the heater systems. A form of active solar heating.
