Evaluation of the Solar Energy Potential for Photovoltaic System in Surabaya

The energy output from a photovoltaic (PV) system depends on both device character istics such as efficiency, and surrounding factors where the device is being operated. This paper discusses the aspects related to evaluation and assessment of solar energy potential in a certain location by taking Surabaya as the case of study. The aspects are including solar geometry and position, component of solar radiation, and calculation of amount of solar insulation that can be expected. Results of measurement of global solar radiation in Surabaya (year 2008) shows that global radiation varies from 3.62- 6,10 kWh/m2 with an average of 4,92 kWh/m2. The average of ambient temperature during day time was 32°C. The simulation results shows that, for the fixed panel position, t be most effective of azimuth a ngle is 0° (facing north) with a sloping panel of 15°
