Customer ServiceDish/engine systems use a parabolic dish of mirrors to direct and concentrate sunlight onto a central engine that produces electricity. The dish/engine system is a concentrating solar power (CSP) technology that produces smaller amounts of electricity than other CSP technologies—typically in the range of 3 to 25 kilowatts—but is beneficial for modular use.
Customer ServiceSolar irradiation may be transformed into useful thermal energy using solar concentration collectors. These collectors often use a reflector to focus solar heat fluxes into a central point or line, thereby making it easier for a heat transfer fluid (HTF) to absorb the heat.
