Sumitomo Electric Industries Ltd has commercialized a solar cell module equipped with a concentrator system and delivered the first product to the Kibana Campus of the University of Miyazaki.
The solar cell module uses small-size multi-junction (MJ) compound semiconductor photovoltaic (PV) cells and collects light with a Fresnel lens. The thickness and weight of the module are about 100mm and less than 10kg, respectively. On the top of a pillar whose height is 8m, 64 modules are installed. The 64 modules measure 7 x 6m and have a rated output of 7.5kW or higher. Sumitomo Electric purchased the PV cells from outside the company.
