Sun simulator for Bifacial modules with double light source
Ecoprogetti is innovating once again with a New LED Sun Simulator specifically designed to automatically get the most precise and realistic results for Bifacial PV panels. Ecoprogetti’s ECOSUN Bifacial is a LED sun simulator designed to simultaneously test both sides of a bifacial module. The test is carried out in one step, with no need to move or flip the panel nor to repeat the operation. One LED unit is placed on top of the module, illuminating at 1200 W/m², and the second unit illuminates the rear side at between 100 and 1200 W/m².
The double light source system ensures a much faster testing speed for bifacial modules, testing them in just one step and simulating the final installation conditions of the modules as on the field/rooftop, where the light is coming and reflected on both sides. Being the light reflected to the rear side of the module the biggest variable, it’s important to provide to the final client the possibility to replicate as many test conditions as possible. To have a highly flexible model of the environment of installation, and therefore to arrange a high level of irradiation on the rear side is a key element for future developments for measuring the bifacial performance.
