Passive solar power systems

TES systems have somewhat more variety of use. Passive solar power systems used in houses and commercial buildings soak up energy from the sun that can be used to heat interior water or air. Likewise, systems that use off-peak energy to make ice that later contributes to refrigeration operate in large buildings to save electricity costs. For instance, the Dallas Veterans Allairs Medical Center incorporated a chilled-water TES that reduced electricity consumption nearly 3,000 kW and saved more 200,000 in its first year of operation. 

Solar Thermal Collector A device designed to receive solar radiation and convert it into thermal energy. Normally, a solar thermal collector includes a frame, glazing and an absorber, together with the appropriate insulation. The heat collected by the solar thermal collector may be used immediately or stored for later use. Typical use is in solar hot water heating systems. Also, see Passive Solar and Concentrated Solar Power (CSP). ...
