A numerical model to predict the behavior of a novel concept of a hybrid system composed of photovoltaic-thermal solar panel and heat pipe is presented hereby. This model has been developed to assess the performance, and energy conversion process of the hybrid system as well as the individual efficiencies of this process to produce hot water and electricity. The two-dimensional heat transfer and fluid flow dynamic model was developed to describe the behavior of a hybrid system under different conditions, namely; solar irradiance, heat pipe conditions and different refrigerants. The model is based upon the dynamic mass and energy equations coupled with the heat transfer formulas, and thermodynamic properties of refrigerants as well as thermal material properties of the PV solar panel and heat pipes. Finally, the model's prediction has been validated and fairly compared with available experimental data.

“…It is well known that the cell temperature impacts the PV output current, performance and its time-variation can be determined from [18][19][20][21][22]. The AC power of the inverter output P(t) is calculated using the inverter efficiency η inv , output voltage between phases, neutral V f n , and for single-phase current I o and cosϕ as follows:…”

“…It is assumed that T m is equal to the surface temperature of the heat exchanger tubes welded to the solar PV cell/panel in close contact to the back surface of each of the PV cells. The heat transferred from the back of the PV cell to the heat transfer fluid flowing in the heat exchanger tubes as shown in Figure 1 is computed by the following forced heat transfer convection relationship [16,19]:…”

A numerical simulation model for a novel concept of a hybrid composed of photovoltaicthermal solar panels and a heat pump is presented. This concept was developed to assess the performance and energy conversion efficiency of the hybrid system used to produce domestic hot water and electricity. A two-dimensional heat transfer and fluid flow dynamic model was developed to describe the behavior of the hybrid system under different solar irradiance, heat pump boundary conditions and different refrigerants. The model is based on dynamic mass and energy equations coupled with the heat transfer coefficients, and the thermodynamic properties of refrigerants as well as material properties. The model compared fairly to experimental data.

Purpose This paper aims to develop a selective energy optimisation of the photovoltaic–thermal (PV/T) system performance. The PV cell inside the PV/T system could be periodically manipulated to produce domestic hot water without applying an external power supply. Design/methodology/approach A numerical simulation model of the proposed PV/T model was developed in MATLAB/Simulink to analyse the selective energy optimisation of the model. The extrinsic cell resistance (Rse) is adjusted to control the ratio of thermal to the electrical energy, generated from the PV cell inside the PV/T system. Therefore, the internal heat of the PV cell inside the PV/T system is periodically used as a thermal element to produce electrical power and hot water. Findings The optimisation of PV/T energy shows that the electrical power efficiency can increase by 11.6% when Rse was 0 Ω, and the 200 L water tank temperature increased by 22ºC when Rse was 50 Ω. Originality/value This study showed that the use of the PV cell could be extended to domestic hot water and space heating, and not only for electricity.
