Performance Comparison of 3 Kwp Solar Panels between Fixed and Sun Tracking in Palembang - Indonesia

Abstract

Photovoltaics or also called solar cell is a technology that can be used directly into electrical energy in DC currents. The voltage generated by solar cells on available solar radiation. Photovoltaic systems can be improved by several methods, one of which is by installing solar panels. The pattern is mounting with solar tracking system into a solution to increase energy efficiency. This paper is a case study to analyse and compare the performance of different photovoltaic systems in its mounting pattern. Analysis and comparison of the photovoltaic (PV) system consist of 3 KWp Fixed Mounting Photovoltaic and 3 KWp Sun Tracking Photovoltaic with the same type of silicon monocrystalline. The solar photovoltaic system is located in Plaju Palembang (South Sumatra, Indonesia) where the daily irradiation rate is 4.96 kWh / m2. To find out the power production rate, data collection is done for three months in December 2017, January 2018 and February 2018. During the rainy season like December 2017, Fixed Installation of Photovoltaics has greater than 0.4% Sun Tracker Photovoltaic. In the dry season, Sun Tracker Photovoltaic has 0.5% greater interference than Photovoltaic Fixed Mounting. The maximum efficiency in Photovoltaic Fixed Installation is 12.4%, while the maximum efficiency of Sun Tracker photovoltaic is 13%.
