AbstractThe efficiency of photovoltaic (PV) modules is inversely correlated with their operating temperatures. Extensive research has shown that cooling PV systems to maintain a stable and low surface temperature enhances PV efficiency, power generation and prolongs the life span of the modules by limiting the degradation caused by thermal fatigue. The extracted heat can be potentially recovered by the rest part of building energy service systems. To implement this, Building Integrated PV-Thermal systems can be integrated with low temperature heating systems, such as existing heating and ventilation installations running on low-temperature level or integrated with heat pumps. BIPVT technology has however not disseminated successfully and this aspect is insufficiently investigated in current literature. The purpose of this study is to highlight vital performance and integration characteristics of BIPVT as well as roadblocks to their widespread adoption.
