Abstract

The effects of color coating and insulation on the power generation performance of building-integrated photovoltaic (BIPV) systems were experimentally analyzed. A mock-up test bed was constructed, and the irradiance and power generation were measured for one year using south-facing modules. The analysis included colorless (reference), red (Color A), and dark blue (Color B) modules under both insulation (I) and noninsulation (NI) conditions. The output of the Color B module was higher than that of Color A owing to the higher light absorption efficiency of the shorter blue wavelengths. Under insulation conditions, the performance ratio (PR) of Color A was lower by –12% to –24% and that of Color B was lower by –2% to –10% than that of the reference, mainly owing to heat accumulation from suppressed rear heat dissipation. The power generated by BIPV modules is strongly influenced by building envelope factors, such as the coating color and insulation structure.
