first row of panels are up.

We're finished with the first row of panels. The wiring of the panels is pretty simple. The panels have a positive and negative end that have male/ female connectors. One panel's negative end connects to the next panel's positive end until reaching the end or the 7th panel which ever comes first. The negative end connects into the combiner box to the ground bus bar. The positive end will go into the combiner box and connect to the fuse. If you are only using up to 3 series of panel rows, you can connect directly to the Sunny Boy inverter. There is a small grounding clip that goes between each of the panels that fits on the top mounting clamp. At the end of the panel a grounding clamp needs to be placed to fasten the grounding wire that goes into the combiner box and clamp onto the grounding bus bar. Each panel has 4 top mounting clamps, two on each side of the panels that a nut is secured onto the the bolt that is in a channel on the top of the rail. The first and last panels on the outsides are only holding the one panel on, but all the ones in the middle secure adjacent to each other.
