Abstract

The excess heat that is generated from PV modules can be removed and converted into useful thermal energy. A photovoltaic/thermal (PVT) module is a combination of photovoltaic module with a solar thermal collector, forming one device that converts solar radiation into electricity and heat simultaneously. In general, two types of PVT can be distinguished : glass-covered PVT module, which produces high-temperature heat but has a slightly lower electrical yield, and uncovered PVT module, which produces relatively low-temperature heat but has a somewhat higher electrical performance. In this paper, the experimental performance of water type PVT combined module, glass-covered, analyzed. The electrical and thermal performance of the module were measured in outdoor conditions, and the results are analyzed. The results showed that the thermal efficiency of the PVT module was 27.6% average and its PV efficiency was about 10.0% average, both depending on solar radiation, inlet water temperature and ambient temperature.
