Output energy of photovoltaic module directed at optimum slope angle in Kuala Lumpur, Malaysia

Abstract

This research analyzes the optimal choice of the tilt angle for (PV) module sequentially to collect the maximum power. The tilt and slope angles of a Photovoltaic (PV) array affect the amount of occurrence solar radiation exposed on the array. It based on the measured values of daily global and diffuse solar radiation on a horizontal surface which generate the maximum power. It had shown the different optimal angle of tilt (β) for each direction during sunny days per year. To allow to collected the maximum power energy for Kuala Lumpur site on yearly bases. The influences of PV roofing orientation on the power output of PV modules are also investigated. Annual optimum tilt angle is found to be approximately equal to latitude of the location was 15° at South direction. Compared with the different optimum tilt (β) and four directions. Results give implementation for the optimum tilt angles for BIPV applications. © Medwell Journals, 2011.
