Paper Title
Computer Based Solar Position Tracking Using Astronomical Algorithms

This paper presents an innovative method of tracking the solar panels which are used for power production purposes in the renewable energy market. This computer based simple, low cost and efficient technique offer the possibilities of intelligent sun tracking mechanisms for photovoltaic systems. For that an algorithm containing astronomical equations is designed and programed through computer which drives the motors that rotate the panels in precise angles. The proposed design can be used in any part of the world regardless of the sun rise and sun set timings. The panel will exactly locate the position of the sun instead of heat or light and thus improves the efficiency and reduces the vibrations that occurs in the presence of clouds. The validity is checked through different model predictions and comparisons and the results are verified. Indexterms - Excel Macro, Visual Basic for Applications (VBA), Chronological Tracking.
