Abstract
Within the IEA PVPS Task 13, a group of experts representing several leading R&D centers, universities and project developers/EPC companies, is developing a framework for a quantitative analysis of yield assessments (YAs). Several sites were selected in different climates and partners were asked to provide independent yield assessment based on their best practices and/or their own developed simulation tools. The results were analysed and uncertainty reduction scenarios were studied. The final aim is to link the uncertainty framework and the scenarios with cash flow models and Levelized Cost of Energy (LCOE) calculations compared to real case studies.
