62000H-S series -
Chroma ATE Inc.
The latest programmable solar array simulator power supply 62000H-S Series released by Chroma provide simulation of Voc (open circuit voltage) up to 1800V and Isc (short circuit current) up to 30A. The 62000H-S provides an industry leading power density in a small 3U high package. The solar array simulator is highly stable and has a fast transient response design, which are both advantageous to MPPT performance evaluation on PV inverter devices. The 62000H-S Series have many unique advantages including high speed & precision digitizing measurement circuits with a 100kHz A/D, 25kHz D/A controlled I-V curve and a digital filter mechanism. It can simulate an I-V curve accurately and response the mains ripple effect from the PV inverter. In addition, the built-in EN50530/Sandia SAS I-V model in the standalone unit can easily program the Voc, Isc, Vmp, and Imp parameters for I-V curve simulation, without a PC controller.

Optosolar GmbH
For series connected multijunction cells, at a given spectrum (e.g. AM 1.5 or AM 0 for space solar cells), one of the cells will limit the current in the series connection of cells. All solar simulators deviate from the true AM 1.5 spectrum, and they are only classified in wide spectral bands (100nm width). So even for class A or A+ solar simulators, it can easily happen that the bandgaps of the multijunction cells are such distributed that the 'wrong' cell will limit the current, if a solar simulator with fixed spectrum is used. In the 70s and 80s, when these measurements were first developed, intercomparisons showed deviations of cell efficiency in fixed spectrum solar simulators of more than 40%.

Optosolar GmbH
Solar simulators enable the measurement of (dark and) light IV characteristics and of power and efficiency of photovoltaic An artificial light source is used to create illumination conditions that are similar to those in natural sunlight. International standards hosted by ASTM, IEC and JIS allow to classify the properties of a solar simulator with respect to spatial light uniformity, spectral content of the light and time variation of intensity.
