How to Connect Your Solar Panels in Series and Parallel
These videos show how to connect two 100 watt solar panels in parallel and series using MC4 branch connectors. For a parallel connection, connect positive leads with one adapter and negative leads with another adapter, and then connect to the adapter kit. For a series connection, connect the negative lead from one panel with the positive lead from the other, and then connect the remaining positive and negative leads to the adapter kit. A parallel connection maintains a 12-volt system, while a series connection creates a 24-volt system. These can be connected to a 12-volt or 24-volt battery bank, respectively, using a PWM charge controller.
