Also, at the installation site, persons without electrical experience may easily perform on-site installation of the BIPV panels. Accordingly, the BIPV panel 200 may comprise a wiring channel dimensioned to provide a passage for wiring bussing. In this way, the wiring will remain concealed on the exterior of the BIPV panel 200.
