Mechanisms for Improving the Productivity of the Existing Photovoltaic Panels: A Review

Increasing the productivity of the photovoltaic panels is a major problem in recent developments. An existing operative solar panel is far from being optimized, because of the critical problems like weather changes, dust deposition and stains deposited over it. Weather changes are due to temperature, humidity, and cloudy atmosphere, dust deposition due to plants, traffic, air pollution and stains due to birds shit. Brief overview of different existing methods to boost the capacity of these panels is given in this paper. These available existing methods are: tracking system with panel, anti-reflecting coating for solar panels, dust cleaning by various methods and cooling of the panel.
