Abstract EN
Photovoltaic-thermal (PVT) collectors combine photovoltaic modules and solar thermal collectors, forming a single device that receives solar radiation and produces electricity and heat simultaneously.
PVT collectors can produce more energy per unit surface area than side-by-side PV modules and solar thermal collectors.
There are two types of liquid-type flat-plate PVT collectors, depending on the existence of glass cover over PV module: glass-covered (glazed) PVT collectors, which produce relatively more thermal energy but have lower electrical yield, and uncovered (unglazed) PVT collectors, which have relatively lower thermal energy with somewhat higher electrical performance.
In this paper, the experimental performance of two types of liquid-type PVT collectors, glazed and unglazed, was analyzed.
The electrical and thermal performances of the PVT collectors were measured in outdoor conditions, and the results were compared.
The results show that the thermal efficiency of the glazed PVT collector is higher than that of the unglazed PVT collector, but the unglazed collector had higher electrical efficiency than the glazed collector.
The overall energy performance of the collectors was compared by combining the values of the average thermal and electrical efficiency.
