A Review of Mathematical Models for Performance Analysis of Hybrid Solar Photovoltaic - Thermal (PV/T) Air Heating Systems

Abstract:

In recent years, many researches are being carried out on the integration of solar thermal systems with solar photovoltaic modules in many countries for heat generation along with electricity generation. The electrical energy generated by the solar PV modules is utilized for the operation of fan. The hybrid solar photovoltaic - Thermal (PV/T) technology provides an opportunity to enhance the electrical and thermal performances. This paper deals with analysis of various parameters which affect the electrical and thermal performances of different types of hybrid solar photovoltaic - Thermal (PV/T) air heating systems. These systems deliver more useful energy per unit area of the heater than that of individual solar PV and solar thermal systems and can be used for preheating the air for many applications such as drying of agricultural products, space heating and industrial process heating. The performance comparisons among the various models reveal that the model III in which the air flows above and below the absorber plate is most suitable for converting the solar energy into high quality electrical energy and low quality heat energy.
