Abstract
A solar heat and power hybrid system can simultaneously generate electricity and thermal energy. In this study, several experiments were carried out with a solar heat and power hybrid unit. Then, a method to increase the photovoltaic efficiency and amount of thermal energy was suggested based on a comparative analysis. The experiment was conducted using only the photovoltaic system as a reference case, with the photovoltaic-thermal air system as a hybrid case. A numerical increase in the photovoltaic efficiency per $1^{\circ}C$ was suggested based on a comparative data analysis of these two cases. In this experiment, the surface temperature on the air hybrid system was $13.52^{\circ}C$ lower than that in the reference case, and the photovoltaic efficiency was increased by 5.09. The amount of thermal energy produced was 15.69 Wt per $1^{\circ}C$ difference between the ambient and outlet temperatures. In this paper, therefore, a photovoltaic efficiency increase of 0.34 per $1^{\circ}C$ is proposed for the air hybrid system based on the analysis of the experimental data.
