The solar irradiation falling on PV-module that converted into heat hence the reducing efficiency. The dust deposition decreases efficiency and resist the amount of solar radiation interacting on surface of PV-panel. The mismatch position placed of PV string can make the mutual shading between the PV-Module, Due to this reason of shading the totally efficiency of PV system falls. To overcome all mentioned problem, in this paper the review of environmental factor and their latest minimizing techniques for optimizing performance of PV-Module is discussed. This paper merely focused on the review of cooling, Cleaning and shading effect techniques.

In this paper, we propose a thermal model of a hybrid photovoltaic/thermal concentration system. Starting from the thermal balance of the model, the equation is solved and simulated with a MATLAB code, considering air as the cooling fluid. This enabled us to evaluate some of the parameters influencing the electrical and thermal performance of this device. The results showed that the temperature, thermal efficiency and electrical efficiency delivered depend on the air mass flow rate. The electrical and thermal efficiencies for different values of air mass flow are encouraging, and demonstrate the benefits of cooling photovoltaic cells. The results show that thermal efficiency decreases air flow rate greater than 0.7 kg/s, whatever the value of the light concentration used. The thermal efficiency of the solar cell increases as the light concentration increases, whatever the air flow rate used. For a concentration equal to 30 sun, the thermal efficiency is 0.16 with an air flow rate equal to 0.005 kg/s; the thermal efficiency increases to 0.19 with an air flow rate equal to 0.1 kg/s at the same concentration. An interesting and useful finding was that the proposed numerical model allows the determination of the electrical as well as thermal efficiency of the hybrid CPV/T with air flow as cooling fluid.

Interest in solar energy is growing by the day, because it is clean and unlimited. Concentrated photovoltaic-thermal (CPV/T) systems are one of the systems that are attracting a great deal of attention among solar energy systems. In this work, a study of a hybrid concentrated photovoltaic-thermal (CPV/T) system that enables the simultaneous production of electrical and thermal energy has been presented. As the experimental realization of such devices is costly, it is necessary to develop numerical models. The aim of this work is to evaluate the thermal efficiency of the system based on the thermal model, using an iterative simulation procedure. Propose a numerical model to evaluate the thermal efficiency of a CPV/T hybrid system. Starting from the energy conservation equations, a numerical modelling and simulation of the concentrated photovoltaic-thermal hybrid (CPV/T) system is carried out. A parametric analysis is carried out to study the influence of concentration, water mass flow rate, cell surface area and Reynolds number on the system's thermal and electrical performance. The results show that thermal efficiency decreases with increasing Reynolds number and mass flow rate. However, it increases when the water mass flow rate is equal to 0.0001kg/s, from 0.4% to 0.7%, for a flow rate equal to 0.0010kg/s. An interesting and useful finding was that the proposed numerical model allow the determination of the electrical as well as thermal efficiency of the hybrid CPV/T.
