Optimization of tilt angle on-grid 300Wp PV plant model at Bukit Jimbaran Bali

Abstract

Abstract Optimum tilt angle of the photovoltaic (PV) modules are needed for determining the optimum solar energy producing in some specific area. Currently, there is no data for the optimum tilt angle in the area of Bukit Jimbaran Bali. In this paper, the optimization of the tilt angle of the on-grid 300-Wp PV plant model is presented using the PV system software simulation with solar radiation data are from Metronome 7.2. The system specifications on this research use a standard type module system, ground base disposition mounting, monocrystalline cell technology, and free-standing ventilation property. Using azimuth from 0 to 180 degrees in each direction and tilt angle from 0 to 90 degree with 1-degree interval, the simulations found that for fixed solar panels in a year, the optimum tilt angle values are from 12 to 18 degree in the azimuth of 0-degree direction with the system output at 528 kWh/year. The tilt angle is changed every six months, and for April to September, the optimum tilt angle is 32 degree at the azimuth of 0 degrees, while in October to March is in 24 degrees at the azimuth of 180 degrees with the system output at 561 kWh/year.
