There are a few things to consider when connecting solar panels with alligator clips. The first is the size of the alligator clips. They should be big enough to accommodate the thickness of the solar panel's wires. The second is the material of the alligator clip's jaws. They should be made of a conductive metal, such as copper or aluminum, in order to create a good connection with the solar panel's wires. Finally, it is important to make sure that the alligator clip's jaws are clean before making any connections. This will help to ensure a good connection and minimize any resistance.
