Study of sufficient number of optimal tilt angle adjustment to maximize residential solar panels yield

In this paper a comprehensive study is carried out on the optimal number of intervals for adjusting the optimal tilt angle of a solar panel. The tilt angle of solar panels is important for capturing solar radiation and it depends on the path of the sun in the location of the solar panel. A Bee Algorithm is used to compute the optimal tilt angle for a given period. The main goal is to show instead of using a tracking system, which is costly for residential usage, manual adjustment of the tilt angle of a solar panel for a certain number of times during a year is sufficient to receive most of the solar radiation. This study is performed for different locations across the US with different latitudes and longitudes. The optimal number of intervals for each location is computed and the effects of the changes in the longitude and latitude are investigated.
