Optimization of a Photovoltaic Power Plant in Indonesia with Proper Tilt Angle and Photovoltaic Type using a System Advisor Model

Aiman Setiawan, Eko Adhi Setiawan


Abstract: As a tropical country,
Indonesia has great solar energy potential, with an average solar radiation
intensity of 4.8 kWh/m2/d. Consequently, the optimization of solar
power plants in Indonesia is necessary. The objective of this paper is to
investigate solar panel optimization in Indonesia using system advisor model
(SAM) software. Optimization focuses on two main concerns, choice of
photovoltaic (PV) type and optimum PV tilt angle. Research is conducted in
three different cities in Indonesia. The annual energy production simulation is
conducted on 5 kWDC PV on-grid systems with different PV types and
slope angles. According to simulation results, Indonesia has a relatively low
proper PV tilt angle, with a value of 11o, 11o and 6o
for Jakarta, Makassar and Jayapura,
respectively. It can also be derived that when compared to crystalline PV
modules, thin film PV modules have better performance, with the highest annual
energy production due to its temperature coefficient characteristics.
Keywords: Cost of energy; Photovoltaic; PV tilt angle; System advisor model; Temperature
