“…3 A new configuration was presented in Saygin et al 4 The PV panel was cooling using a counter air flow by forcing the air to pass through an opening at the middle of the collector cover. Mojumder et al 2 developed a simulation model to study the effect of length and height of aluminum fins used to cool the back surface of PV cells using duct embedded below the PV panel.…”

“…One of the suitable methods to attain uniform distribution of PV panel surface temperature is by using coverage channel to increase the flow speed at exit. 3 A new configuration was presented in Saygin et al 4 The PV panel was cooling using a counter air flow by forcing the air to pass through an opening at the middle of the collector cover. The effect of the PV panel position and the thickness of air gap were investigated to achieve the optimal design.…”

Summary A hybrid solar photovoltaic/wind system is proposed and investigated theoretically. The hybrid system is based on attaching a converging inclined duct beneath the photovoltaic (PV) panels and directed upward after the end of the panels. A wind turbine is attached at the exit of the converging duct. The converging duct will capture wind currents that at its inlet and enhances these current by buoyancy effect created by the rejected heat from the panels. The mixed convection air flow is used in cooling the PV panels and in generating electricity by driving the wind turbine at the duct exit. A mathematical model is proposed to describe the system hydrodynamic and thermal behavior. In addition to the mixed convection case, the pure free convection case, when there is no wind speed, has been tested. The design of the wind duct capturing system is not included in this study, which should be carefully manufactured to eliminate the reversed flow. The simulation results show that the integration of both systems not only enhances the performance of PV cell due to the effective cooling but also generates more electric power from the inserted turbine. At low wind speeds, it is found that the ducting system helps more in cooling the panels rather than driving the wind turbine. At these low wind speeds, the buoyancy effect may have a significant effect. However, at high wind speeds, the ducting system acts in both cooling the panels and driving the turbine, and at these high speeds, the buoyancy effect is insignificant.

“…In another study, the electrical and thermal efficiencies of a modified PVT configuration were assessed empirically. In this assessment, the effect of the mass flow rate on the electrical and thermal efficiency were studied, and it was demonstrated that increasing the mass flow rate improved the thermal performance, but did not have an impressive effect on the electrical efficiency [39]. In 2017, Slimani et al [40] presented an electrical-thermal model for three different photovoltaic/thermal collectors and photovoltaic modules in order to compare the efficiencies of the proposed configurations.…”

A main method to increase the solar energy utilization efficiency is to combine heat and power generation together. In this paper, a critical review of the literature on solar combined heat and power systems (CHP) is conducted, which includes solar photovoltaic/thermal systems, concentrated photovoltaic/thermal systems, and various combination with different solar collectors and applications. It shows that there are serious gaps in this field, which calls for more research. The modeling and analysis of the electrical parts of the CHP systems are not adequate, and there are limited studies on the economic and exergy assessments of the solar concentrating CHP systems. The solar collectors for combined CHP were focused on optimizing the performance of the maximum average useful power generation and minimum total heat transfer area, little environment impact analysis was conducted. Careful exergy, economic and environmental analysis on both electronic and thermal performance is suggested, especially for large CHP system.

“…In recent times, the performance of PVT air collectors is improved in terms of energy output and cost-effectiveness (Kima et al, 2014;Sun et al, 2016;Shams et al, 2016;Dissa et al, 2016;Su et al, 2017;Saygin et al, 2017). It is credited to the modification in design and incorporation of new solar cell technologies (materials) which increase the efficiency and reduces the overall cost of the system.…”
