Company Profile:
A high-efficiency photovoltaic device containing two or more cell junctions, each of which is optimized for a particular part of the solar spectrum.
Industry:Energy
A high R-value insulation product usually made from urethane that can be injected into wall cavities, or sprayed onto roofs or floors, where it expands and sets quickly.
Industry:Energy
A high efficiency silicon photovoltaic concentrator cell that employs light trapping techniques and point-diffused contacts on the rear surface for current collection.
Industry:Energy
A heating unit where heat is distributed by means of convection or fans.
Industry:Energy
A heating system where heat is supplied (radiated) into a room by means of heated surfaces, such as electric resistance elements, hot water (hydronic) radiators, etc.
Industry:Energy
A heating system that uses only outside air for combustion and vents combustion gases directly to the outdoors. These systems are less likely to backdraft and to negatively affect indoor air quality.
Industry:Energy
A heating system in which steam or hot water for space heating or hot water is piped from a central boiler plant or electric power/heating plant to a cluster of buildings.
Industry:Energy
A heat storage system that uses a heat storage medium, and where the additional or removal of heat results in a change in temperature.
Industry:Energy
A heat source, such as a space heater, used to provide more heat than that provided by a primary heating source.
Industry:Energy
A heat exchanger that transfers the heat contained in a liquid heat transfer fluid to air.
