Automatic Dual Axis Solar Tracking System

Abstract

Solar energy has gained tremendous attention in recent years due to various reasons such as a fluctuating of price of crude oil awareness of public on environment issues, supporting policies and subsidies taken by local government to boost renewable energy sectors, and prize reduction of photovoltaic (PV) panels.  Due to depletion of major conventional energy sources like petroleum, coal and natural gas. It has become urgent necessity to invest in renewable energy sources that can power the future sufficiently. Solar panels directly convert radiation from the sun into electrical energy. This paper seeks to identify a way of improving solar panels.’ For solving the problem of electricity and power the best solution or the market need is dual axis solar tracker system.’ The tracking mechanism moves and position solar array such that it is positioned for maximum power output.  There are various type of tracker can be used for increase in the amount of energy that can be obtained by solar panels. Dual axis trackers are among the most efficient, though these comes with increased complexity. Dual axis tracker is the solution of big problems that is electricity. It helps to the development of new type of sensor system that is able to track the sun correctly and also in the development of prototype solar panel holder with to axis actuator mechanism at elevation and azimuth.
