Abstract.

This study investigates the shading on PV systems. Shading has considerable influence on the solar cells characteristics, temperature and radiation on site need to be considered as the basis for designing PV systems. Modeling conducted on a 1 kWp PV system at a latitude of 6°53'2.69"S and a longitude of 107°32'28.69", to find the magnitude of solar radiation, surface temperature, and tilt angle, and partial shadow simulation using PVsyst software. Testing result shows the characteristic PV 1 kWp is obtained with the angle of solar cell shade at 18˚ and azimuth 0˚, the shading per year generates 4.71 kWh/m
in a solar active area at 6.9m 22, the power losses of 20.8% of its nominal power.
