You cannot legally or safely become a Solar Photovoltaic (PV) installer without first qualifying as an electrician. There is no legitimate "PV-only installer" pathway bypassing electrical competence requirements. Solar PV systems comprise DC (Direct Current) arrays on rooftops generating electricity, feeding inverters converting DC to AC (Alternating Current), then integrating into building electrical installations at consumer unit level. The AC connection work falls under BS 7671 Wiring Regulations requiring circuit design, protective device selection, earthing verification, cable sizing for voltage drop and current-carrying capacity, and initial verification testing identical to adding any final circuit to electrical installation.
