Regulations and certification systems have been installed in many building-applied renewable energy systems (BARESs). Efforts to investigate and maintain the performance of renewable energy systems (RESs) have been lacking from the perspective of users or facility managers. This maintenance issue has obstructed the RES from operating in terms of its original purpose. Therefore, in this study, the operation status is evaluated through a power generation performance analysis on building attached photovoltaic (BAPV) systems, which are representative BARESs. The average performance ratio (PR) was 68.97%, with 78.42% in 2012 when monitoring started and 62.34% after 6 years. The PR continued to decline over time, with a difference of 16.07% between 2012 and 2018. In addition, the losses were 2.22%, 3.14%, 3.51%, and 22.16% over the entire period for the balance of the system (BOS), module temperature, incident angle modifier, and miscellaneous losses, respectively. Although other losses did not change over time, the miscellaneous loss was 10.43% in 2012, which increased to 29.49% in 2018. The BAPV system has experienced a continuous performance degradation since 2012. This indicates that managers have conducted no maintenance or performance surveys. Furthermore, more power can be generated by the BAPV system if maintenance is regularly conducted. The literature review has shown that a system installed for regulation or certification is not maintained, and that the facility managers are being challenged. Therefore, it is necessary to consider means to guide the maintenance points or methods applied.
