A low cost, high flux, large area solar simulator has been designed, built and characterized for the purpose of studying optical melting and light absorption behavior of molten salts Seven 1500 W metal halide outdoor stadium lights are used as the light source to simulate concentrating solar power (CSP) heliostat output Metal halide bulbs and ballasts are far less costly per-watt than typical xenon arc lamp solar simulator light sources They provide a satisfactory match to natural sunlight although unfiltered' metal halide lights have irradiance peaks between 800 and 1000 nm representing an additional 5% of measured energy output as compared to terrestrial solar irradiance over the same range With the use of a secondary conical concentrator, output fluxes of approximately 60 kW/m(2) (60 suns) peak and 45 kW/m(2) (45 suns) average are achieved across a 38 cm diameter output aperture Unique to the design of this simulator, the tilt angle and distance between the output aperture and the ground are adjustable
