Solar panels are integrated into a whole system that combines mounting, wiring, and system integrations. In a manufacturing context, assembly refers to the completion of solar panel backsheets, frames, and junction boxes. For field installations, assemblage secures the various mounts (rails, brackets, or racks) to the panels which electrically connects via MC4 connectors and grounds the system. Proper assembly ensures that the tolerances for optimal airflow and heat dissipation are within a two millimeter threshold. Checks for quality assurance encompass testing insulation resistance and visually inspecting the module for damage. Meeting the requirements of IEC 61215 and codes for local area electrics is an absolute requirement to guarantee safe and efficient energy production.
