Paper Abstract
To simulate solar radiation at the earth's surface, a new economical multiple-lamp solar simulator was designed. The
solar simulator is comprised of 188 reflector sunlight dysprosium lamps whose light spectrum is very similar to air mass
1.5 (AM1.5) solar spectrum terrestrial standards. Lamps are configured in a hexagonal pattern with 15 columns of 12 or
13 lamps at a lamp-to-lamp spacing and column-to-column spacing of 295mm. Without altering the radiation spectral
distribution, the average irradiance on target irradiated area can be adjusted over a wide range between 150 and
1100W/m2 by means of the variation of lamps number or/and lamp-to-irradiated area distance. At the height of 2.0m the
solar simulator provides 2m×1.5m irradiated area with over 1000 W/m2. Measurement of irradiance indicates that the
multiple-lamp simulator conforms to Class B of ASTM (American Society for Testing and Materials) Standard (ASTM
E927-2005) in regard to spectrum match, irradiance uniformity and stability. To enlarge the effective irradiated area, two
large mirror-like stainless steel plates was mounted on both of the long sides of the solar simulator. The radiation
characteristics of simulator are improved and the optimized effectively irradiation surface is expanded up to 81.6%.
