Abstract: This study analyzes the optimal choice of the tilt angle for (PV) module in order 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. The study is based on the measured values of daily global and diffuse solar radiation on a horizontal surface which generate the maximum power. It is shown that 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 and monthly bases. The influences of PV roofing orientation on the power output of PV modules is also investigated, the module surface is assumed to be facing toward basic orientation with different angles. 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 reasonable solutions for the optimum tilt angles for BIPV applications for grid-connected system.
