A PVT SYSTEM and its competition for a one family house

摘要

Over the past few years, PVT systems that combine solar thermal technology and solar PV have gained more attention. IEA SHC started in 2018 the Task 60 called "PVT systems" to better understand the applications of the technology. PVT solutions can be used in several ways Task 60 is currently investigating. Heating or cooling for residential, commercial, administrative or industrial buildings is the main application. In this paper we compare a PVT solution for a single house to other classical solutions chosen by swiss villa owners.We show in this analysis that the PVT solution for a one family house remains expensive while bringing a high solar fraction and the least CO2 emissions. A better cost competitiveness could be reached if the electricity price was higher and if the investment cost could be lower or if the CO_2 emission penalty costs were much higher. The PVT solution can lead to higher heat pump performances and a high renewable energy fraction that could be even 100% with some electrical storage not considered in this study.
