Helios 3198

The Helios 3198 Solar Simulator for CPV provides an indoor CPV module power measurement and classification capability for both laboratory and production line use. The simulator is the end result of 10 years of research and development by the IES-UPM into CPV indoor measurement requirements and techniques, and provides an integrated solution to the complex problems of indoor CPV test: the need for highly collimated light, a large illuminated area, and special attention to spectral balancing for multi-junction cells.

Solar Added Value has industrialized this solar simulator technology, creating a test equipment product that is robust and easy to use and install. The system includes both the lighting system and the I-V curve tracing electronics, as well as a custom design control software package that can be adapted to the needs of each customer, including such functions as module sorting, automatic test, and database integration.


Basic requirements for in-door CPV modules testing

The key challenge to in-door CPV measurement is obtaining a light source that is very similar to the sun, both in spectrum and angular size. Because of the limited angular acceptance of CPV modules, highly collimated light must be used. The SAV-HELIOS® 3198 has a collimation angle that approaches the angular size of the sun, allowing it to detect defects in the alignment of a module optics in a realistic and scientific manner. The 2 meter beam of light produced by the proprietary collimating optic of the SAV-HELIOS® 3198 is uniform spatially, and may be used to to characterize the I-V curve of any concentration technology. The spectrum is matched to AM1.5D but balanced with especial attention accurate measurement of modern III-V multi-junction cells.

Because of the various size and form factors of different CPV modules, the system setup with versatile, with the lamp placed at the collimator focus (on-axis) for smaller modules, and moved to an off-axis position to allow the entire 2m area illuminated area to be used for larger modules or more flexibility.
