Abstract

An autonomous mobile photovoltaic–thermal device (PVTD) was developed to ensure reliable production of both electricity and hot water throughout the year, including during winter and summer seasons. The system creates the required solar radiation intensity even in harsh mountainous and foothill conditions, enabling stable performance under extreme climatic environments. In the experiment, two 200 W monocrystalline silicon photovoltaic (PV) panels and the PVTD were observed simultaneously, and the measurement results were compared through the calculation of power. The backside of the PVTD was equipped with a cooling system. It was also equipped with controllable reflectors that adjust according to seasonal changes in solar flux density. According to the experimental results, it was determined that the amount of energy produced by the PVTD was 1.81 times greater than that of the PV. In addition, by passing cold water at 9 °C through the collector located on the rear front side of the PVTD, usable hot water at 53 °C was obtained at a rate of 20 liters per hour. The experiment was conducted in winter months, under daily air temperatures ranging from –4°C to 5°C.
