Key Messages

With increasing contribution of solar PV based systems in our energy mix, it is crucial to understand their vulnerabilities. Various factors can affect the performance of PV systems. In this context, CSTEP explores questions such as: What is the effect of standard module degradation on plant techno-economics, for locations spread across different climate zones? What is the permissible rate of annual module degradation such that the plant remains financially viable? What is the effect of the cleaning cycle on plant techno-economics (via soiling losses)?
