Optimum tilt angle and orientation for solar collector in Brunei Darussalam

摘要

One of the important parameters that affects the performance of solar collector is its tilts angle with the horizontal. This is due to the fact that the variation of tilt angle changes the amount of solar radiation reaching the collector surface. A mathematical model was used for estimating the total (global) solar radiation on a tilted surface, and to determine the optimum tilt angle and orientation (surface azimuth angle) for the solar collector in Brunei Darussalam on a daily basis, as well as for a specific period.
