Product Briefing Outline: Pasan SA has introduced a new electronic load that is more accurate and offers several additional features for the testing of solar cells and modules. This electronic load not only is fitted to module and cell flashers, but also can be combined with continuous light sources. Furthermore the equipment is suitable for outdoor testing.
Problem: Testing of modules and cells demand higher accuracy and an increasing number of features. This influences the light source as well as the electronic load. Furthermore the line integration and interfacing with control and quality management systems become more and more important.

Solution: First of all the system acquires and processes data much faster than before. It also provides a higher D/A and A/D resolution of 16 bits instead of 12 bits. The maximum current is increased to 50 A in order to enable testing of large panels. For each chanel a deviation of +/- 0.1 % at 25°C is guaranteed instead of formerly +/- 0.2 %. The start of measurement is programmable from the starting point of flash. The new electronic load can also provide up to two different irradiance levels during one flash. By that, series resistance (Rs) on modules can be determined according to IEC standard in one single flash. The new electronic load will be introduced by stages in all Pasan module and cell testers. It also will be available as a stand alone unit.
Applications: Module and cell flashers, continuous light sources, outdoor applications
Platform: All Pasan equipments are based on xenon single-flash technology, giving closest approach to spectral irradiance of sun, with negligible heating of module or cell to be tested. The new electronic load will be introduced in stages in all Pasan module and cell testers. It also will be available as a stand alone unit.
Availability: April 2009 onwards.
