Solar Panel Wiring Methods

WINAICO Wiring Techniques

The Leapfrog Technique

The name of this wiring arrangement is named after the method of skipping every second panel, to wire them together on the return path. WINAICO designed the wire lengths of all the current solar products to facilitate Leapfrogging.

The positive wire of the 1st panel in a string will connect to the ground of the 3rd panel. The positive wire of the 3rd panel will connect to the ground of the 5th and so on. At the end of the string the wiring will return backwards. An image has been provided to help illustrate the technique.

Leapfrogging has several advantages over the 'Daisy-Chain' Technique. The method permits better extension of the wires behind the panels reducing their exposure to the weather. It also does not require a return wire.


Daisy Chain Wiring

The daisy chain method as demonstrated in the image above is another method of wiring panels together. The design is simplier and easier to apply for string panels, especially when a string is not in a straight line.

The longer return wire can be a cause of earthing fault if incorrectly pulled through. Please take care of ensuring the return wire is not damaged during installation.
