Market and simulation analysis of PVT applications for the determination of new PVT test procedures

摘要

PVT collectors produce simultaneously electricity and heat and combine the technologies of PV and solar heatrnin one product. Due to lack of testing and certification standards on energy yield and quality they are by nowrnhardly established in the market. Thus, as part of a joint project the focus was to develop test methods for PVTrncollectors. First, a market research with subsequent typification of PVT products served to identify typicalrnapplications and system circuits of PVT collectors. As a result three typical PVT systems have been modeled inrnsimulation models. Then, as basis of future tests on energy yield and quality of marketable products, bothrntypical and extreme operating conditions of PVT collectors are determined by means of dynamic annualrnsimulations of PVT systems in the simulation environment of TRNSYS. Following the module tests conductedrnby the project partners, exemplary annual simulations and yield forecasts were performed.
