Photovoltaic array distance will be calculated that can have maximum output through the rearrangement of photovoltaic array by comparing and analyzing the power output decrease from the shadows of photovoltaic arrays according to the consideration of incidence angle that is not suitable to the situation of our country among the causes of power output decrease by sampling photovoltaic power generation plants. When relocate simulation result photovoltaic array 1 line, when relocate about 2.8[%], photovoltaic array 3 lines when relocate about 1.2[%], photovoltaic array 2 lines, output of about 5.0[%] improved. Also, gained space gains of photovoltaic array party 1.29[m] when relocate photovoltaic array party 0.82[m], 3 lines when relocate photovoltaic array party 0.39[m], 2 lines when relocate 1 line. As gains occur on photovoltaic array clearance, time that receive effect of shade was slowed down gradually and showed result that elevation of output shows finally.

This paper presents Building Integrated Photovoltaic system of the balcony type which is influenced by conditions such as irradiation, module temperature, shade and array arrangement. When architecture component, trees and cloud shade connecting array in series, total PV array current is reduced. So, before PV system design, a planner have to simulate many situations. And then array should be composed suitable for parallel and series modules. By the results, it is very important to develop optimal design of array considering shade effect for the balcony PV system.
