Its mission short period energy storage, potential longer time storageis to build the most affordable, modular and scalable solar technology would make parabolic dish more appealing.solution in the industry. Designed and developed by Solar Space Frame Parabolic Dish systems use satellite‐like mirror dish(es) Industrial Co.,Ltd the, SolarCatcher™, CSP technology is ato focus the light onto a single central receiver in front of 10 or 25‐kilowatt‐electric (kWe) system generating cleanthe mirror. They so far have the highest heat‐electricity solar energy. The SFI, SolarCatcher™, achieved commercialconversion efficiencies among all CSP designs up to 30 %. deployment at the 2 MW KHO TAO Solar Plant in Thailand in early 2011. The size of the concentrator is determined by its engine.A dish/Steam Turbine system’s concentrator with a nominal The SolarCatcher™ technology makes it possible fordirect solar insolation from 500‐1,000 W/m2 and a 10‐ large power facilities to provide clean, reliable, cost‐kWe@500 W/m2 or 25‐kWe@1,000 W/m2 capacity has a effective and truly sustainable solar power todiameter of approximately 10 meters. communities, while addressing renewable energy portfolio targets, and tackling global climate change by actively It could also run on a single Rankine cycle, where water, reducing our planet’s carbon emissions.or other gas is compressed, heated and expanded into aturbine.
