Comparison of PV System Energy Output Between with and without Solar Tracking: Simulation in a Mountain Area in Indonesia

One of the key performances of a PV system is the amount of solar irradiation received by PV modules. Solar irradiation will be maximum received by solar modules when the angle of incidence is kept 0° using a solar tracker system. This paper studies comparison of the energy output of PV systems between with and without solar tracking in a mountain area of Bromo, Pasuruan, East Java, Indonesia. The studies are carried out using SolarGIS PV Planner simulation. It found that specific energy output PV system with two axes solar tracking system is 2060 kWh/kWp per year, while for the system without solar tracking (fixed optimized), the specific energy production is 1657 kWh/kWp.
