Abstract
The purpose of this study is to deduct BIPV system installation current status and characteristics of BIPV module size and output through case analysis of building integrated photovoltaic systems applied in public buildings by new & renewable energy installation obligation system from 2007 to 2012 and present BIPV system supply performance improvement plan. Analysis by year, capacity, subject organization, facility categorization of BIPV system and size, output by unit area of BIPV module was analyzed. The analyzed results are as follows. (1) BIPV system was installed in 71 locations of 2.7MW from 2007 to 2012 and frequency by BIPV system installation capacity range was highest in 10kW~20kW with 31%. Also, it was most applied in public work facilities with 33.8% and next was education society educational institutes with 26.8%. (2) BIPV module was most installed in building facades instead of curtain walls in which form was G-to-G double-glaing type and G-to-T type with proportion of 38% each. (3) BIPV module size was all under $2m^2$ and most size was $1.0{\sim}1.5m^2$. This size is scarce to replace building material with BIPV module. Therefore, research development on large-scale BIPV module is required. (4) BIPV module output by unit area was most frequent in $100{\sim}125W/m^2$. Based on these results, it is thought that $9{\sim}10m^2$ installation area is required to install 1 kW BIPV system. Also, high-efficiency of BIPV module is required to install BIPV system of more capacity in limited area.
