Determining the optimum tilt angle and orientation for photovoltaic (PV) systems in Bangladesh
Tilt angle of a PV module is one of the most significant parameters for receiving maximum solar irradiation falling on the PV systems. This research article investigates the numerical aspects of selecting the optimal tilt angle for the PV modules used in Bangladesh and makes recommendations on how the collected power output of the module can be increased by altering the tilt angle. The results show that the optimum tilt angle of Cox's Bazzar Chittagong, Dhaka, Jessore, Ishurdi, Bogra, Sylhet and Rangpur is 26°, 25°, 30°, 25°, 27°, 27°, 28° and 29°, respectively. The annual energy production of Cox's Bazar and Sylhet has shown the highest and the lowest energy production, the month was March and July, respectively. The characteristics curves obtained by the simulation with the data provided by using simulated software SAM (System Advisor Model). Finally, the article measures the optimum tilt for PV applications in Bangladesh on Monthly and yearly bases.
