Some solar panels come with wire connected to the wire box on the back of the panel. Attached to these wires are a male and female Solar Connector.
These connectors join two solar panels wires together by simply plugging the two solar panels into a set of these connectors.
It will help make panel installation much easier and additional panels can be added in future by simply adding more of these connectors.
They are dust and waterproof.
The Quick Release Solar Connectors fit into these connectors as well.
