Solar connectors facilitate electrical connectivity in solar energy systems. Numerous versions of connectors or standard non-connector junction boxes are employed in the solar industry and are the primary characteristic elements of solar modules.
The most common variation is the MC4 ("multiple contact, 4 mm pin") product. MC4 components and compatible models account for the majority of solar panels in current use. The male and female pairs are snapped together by hand for easy assembly. Their configuration requires the use of a tool to detach them, making the link more reliable in case the panels move.
