ABSTRACT: In this paper, We have simulated the output variation of the PV arrays installation with position & angle change. The existing 3 solar array system are 43 southeast and each of the mounting angle is 17. The PV output power is 240 kW. The compositestudied systems in this paper arrays altered 2 PV array among 3 PV array system- the output 144kW. We simulated this system using SolarPro ver.4.1. The simulation conditions are southwest 43/array, mount angle 27/array. Because the southeast have shadow effect-higher mountain The purpose of southwest 43 is reduce the shadow effect. The simulation results of the suggestion design algorithm compared to 1,590 kWh/year output is increased with the southeast.

Key words: Photovoltaic, Shadow Effect, Mount angle, Solar Array, Wiring, Surge
