Under trade mark Pasan, Belval S.A. is manufacturing testing systems destined to photovoltaic industry and official laboratories. Her apparatus are based on electronic Xenon single-flash technology, permitting a spectral repartition very close to natural sunlight, and giving negligible heating of device under test .
Appliances are in-process testing for photovoltaic cells and panels and laboratory testing.
A to 30 A. Electronic load is able to measure up to 63 points during one 2 ms single flash. General characteristics are similar, but more functions are controlled by computer, as measuring scales and reference cell sensitivity. Also it is fitted with 12-bits converters. By example it can give Isc at one flash, Voc at another flash or current at predetermined voltage. It is able to measure panels and arrays on-site using natural sunlight.
