As in other photovoltaic systems, an increase in module temperature leads to a reduction in performance in the building integrated photovoltaic (BIPV) system. Therefore, BIPV designers must consider the temperature characteristics of the BIPV at the design stage, and this needs to be reviewed based on long-term data. However, because most previous studies were conducted in the short term under specific weather conditions, it is difficult to obtain basic data on long-term performance. For this reason, this study aimed to provide basic data based on the domestic typical meteorological year by using a simulation for a vertical exterior wall-type BIPV system. The research method was as follows: (i) collect necessary data from the field-installed BIPV system, (ii) establish and verify the simulation model based on the measurement data, and (iii) calculate annual data of the vertical BIPV system using the simulation model. As a result of the study, the surface temperature range, which accounts for 90% of the power generation time under the weather conditions in Daejeon, was 2.5℃ ~ 42.0℃ under ventilator open conditions and 4.7℃ ~ 47.5℃ under ventilated closed conditions. Accordingly, the reduction in module efficiency attributable to temperature increase was as high as 7.2% in the ventilator open condition and 9.6% in the ventilated closed condition. Due to this temperature difference, the power generation difference was as high as about 2% in the winter when vertical solar radiation was high. In the summer, the difference was 1% ~ 1.5%. |
