Both roofs and facades can be explored for the architectural potential of integration. Any part of the roof or external walls that is exposed to sunlight or daylight e.g. skylights, claddings, windows, external shading devices and railings can be used for PV integration. Integration of PV into buildings has the following advantages (Reijenga et
To mitigate land exploitation, building-integrated PV (BIPV) systems, such as solar roof tiles (SRTs), play a crucial role (Victoria et al., 2021; Virtuani et al., 2023).BIPV involves integrating PV modules into the structural elements of a building envelope, such as roofs, windows, or facades, to harness energy from incoming photons and meet building energy
