The Solar Simulator is used for the indoor characterization of modules and other photovoltaic devices under controlled laboratory conditions. The main equipment in the laboratory is a Helios 3198 solar simulator, which features a fixation and alignment structure adaptable to any technology, as well as a spectroradiometer for conducting measurements and tests based on the light spectrum and different wavelengths.

The solar simulator is used to measure the modules under controlled conditions during the screening, verification, and validation processes.
