Title and Abstract of the Speech:
Investigating challenges and solutions for desert PV application
Fraunhofer CSP, Germany
An increasing amount of PV installations is taking place in desert environments. In addition to the advantages of high irradiation values, the desert climate entails increased stress factors for PV modules, which could drastically reduce the power output and PV module lifetime. This especially includes high ambient temperatures and temperature changes, increased losses from soiling and degradation caused by high UV doses. Within the presentation, an overview of challenges of desert PV is provided. Advanced laboratory stress tests, extensive outdoor testing and microstructural investigations help to understand the degradation behavior of the different PV materials. This provides the basis for optimizing used components and PV module design to better meet the increased requirements of desert application. In addition, innovative technologies and solutions for desert PV are investigated with respect to their techno-economical feasibility.
