Part 5 – Watch a solar expert from AS Solar demonstrate how to install a Do It Yourself (DIY) solar panel kit. With this easy to follow guide, you can now easily install a roof solar panel system in your home!
Here in Part 5 it’s time to mount the panels. We start by showing you how to assemble the panel clamps and roughly position them. After that we connect the panel’s wiring to the micro-inverters we installed in Part 4. Up goes the first panel, finger-tightened, and then the second panel. We don’t show the final torquing down of the panel clamps – every panel manufacturer has a different number so we didn’t want to pick a single one.
This section doesn’t show the WEEBs under the panels, so here’s the scoop:
Every panel has to have at least one WEEB. This is easy enough if you install them in a zig-zag pattern. So start with a WEEB on one of the end clamps, say the top at one end of the rail.
Now put another on the bottom mid clamp on the other side of that same panel, between the panel on the end and the second one in.
Now put another WEEB on the top mid clamp on the other side of the second panel, between it and the 3rd panel. Then the lower between the 3rd and 4th, and so on.
This ensures not only that every panel has at least one WEEB even if you remove the panel beside it, but it also grounds the two rails together through the panel frames.
We don’t show the final grounding or how to wire the system into the AC power grid. These are both tasks for a licensed electrician.
