Intelligent solar facades represent a promising approach to reduce the energy consumption of the building and to progress the net goals. The inclusion of concentrating photovoltaics (CPV) technology can generate more electricity, with both environmental compatibility and cost efficiency improving. In this study, we designed, tested, tested and analyzed an intelligent solar liner with a linear concentration element with a concentration ratio of 2.49 ×. For the first time, standard solar cells of the Standard Passiva emitter and back contact (PERC) were integrated into such a configuration. The facade achieved a top performance generation of 174 W/m2, while 63 % of the visible light was transmitted, which maintained a natural daylight in the interiors. The thermal analysis showed that the solar cell reached a top temperature of 339 K under Standard 1 sun lighting (1000 W/m2). In addition, a comprehensive economic assessment showed a repayment in the range of 7 to 11 years in various climate zones, which emphasizes the system of the system for widespread adoption in sustainable building acids. Apart from the traditional economic evaluation, this study includes a holistic sustainability analysis, including embodied CO2 playback, climate adjustable performance and the potential to achieve environmentally friendly certification.
