Abstract
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.
Highlights
PV Technology is one of production of renewable energy the conversion system of solar irradiation into electrical power and having a big potential at current to fulfill the rising energy demand of cities
The solar panel is dusting by electrodynamic screen (EDS) this screen placed on pv module can grantee the automated and constant removal of dry dust deposition without use of liquid or any moving hardware parts [34]
The water-based cleaning technique, semiautomatic mechanism of dusting, labor-intensive cleaning, electro-dynamic curtain solution and so, on is discussed in this paper, it is recommended that the panel must be clean all time
Summary
PV Technology is one of production of renewable energy the conversion system of solar irradiation into electrical power and having a big potential at current to fulfill the rising energy demand of cities. The huge amount of solar energy that falling on PV panel is wasted into thermal energy, and that heat energy produces deterioration in the output power of pv panel due to high temperature [4]. The rise in temperature of pv cell originates a high reduction in the voltage and a little rise in the current, consequent of that total generation is reduced of pv module [5]. The efficiency decreases from 0.35 to 0.8 percent for every 1C of temperature rise in polycrystalline pv module [6]. Whereas the silicon crystalline pv cells efficiency falls by 0.5 percentage with rise of 1C Temperature [8,9]. The major technique to improve the PV module performance that techniques are discussed in detail i.e. cooling PV panel, cleaning latest technique and to minimizing the PS effect techniques
