Market and Simulation Analysis of PVT Applications for the Determination of New PVT Test Procedures
Abstract
PVT collectors produce simultaneously electricity and heat and combine the technologies of PV and solar heat in one product. Due to lack of testing and certification standards on energy yield and quality they are by now hardly established in the market. Thus, as part of a joint project the focus was to develop test methods for PVT collectors. First, a market research with subsequent typification of PVT products served to identify typical applications and system circuits of PVT collectors. As a result three typical PVT systems have been modeled in simulation models. Then, as basis of future tests on energy yield and quality of marketable products, both typical and extreme operating conditions of PVT collectors are determined by means of dynamic annual simulations of PVT systems in the simulation environment of TRNSYS. Following the module tests conducted by the project partners, exemplary annual simulations and yield forecasts were performed.
