Tilt angle estimation for building integrated photo-voltaics-an investigative study

Abstract

This paper demonstrates an investigation procedure to determine the optimum tilt angle for eight different regions of Bangladesh, a country of South Asia situated in the Northern Hemisphere. The work focuses on determining one tilt angle for each region for a whole year and finally finds out the suitable areas to accumulate more incident energy through installing photovoltaic panels that are tilted at an optimum angle. The simulation outcome observation also shows that the energy accumulation increases because of the optimization of the tilt angle of photovoltaic panels. From the result analysis, the paper observed that location-wise the optimum tilt angle varies from 25.57° to 22.10°. Moreover, the study also finds out that the Southern Region of Bangladesh is more suitable to install building-integrated photovoltaic tilting the solar panels at an optimized angle because the tilted photovoltaic panels in the Southern region can harness almost 9%-10% more energy than Northern Region.
