%X The volatile fossil fuel price currently creates an opportunity for the development of alternative approaches in electricity generation. Comprehensive and concerted efforts are focused at developing solar electricity generating system (SEGS). One of the challenges faced by SEGS is the apparent trajectory of the sun. Often, SEGS designers use standard testing conditions, whereby the level of solar insolation is taken to be a constant value of 1000W/m 2. The only value of solar insolation that is taken to be constant is known as solar constant, which is approximately 1353W/m2. Solar constant is the solar insolation received outside the earth's atmosphere. This value drops significantly as the solar radiation passes through the atmosphere, where the typical range is between 150 W/m2 and 1000W/m2. The reducing intensity of solar insolation is also due to the apparent trajectory of the sun. The sun's path changes daily, and in this project, a novel design of the sun tracker has been tested and is able to do two-axis tracking for photovoltaic based SEGS. © 2012 American Institute of Physics. %R 10.1063/1.4757461 %D 2012 %J AIP Conference Proceedings %L scholars2565 %O cited By 2; Conference of 2nd International Conference on Fundamental and Applied Sciences 2012, ICFAS 2012 ; Conference Date: 12 June 2012 Through 14 June 2012 %C Kuala Lumpur %V 1482 %A B.S.
