Installing the solar panels



Started installing the solar panels yesterday
First steps are to measure and drill the mounting holes. My buddy Mike has been assisting during the whole project.




Then wire up the panel (first pre-measure the wire length)


First panel is mounted (not tightened). I was VERY relieved that our hole measurements worked out!


Three panels are in. The downfeed gland is also installed. There will be a combiner box under the last panel. Its output line will go to the downfeed. The hole in the roof was just a tiny bit too small to fit a standard .5" conduit thread. Must be metric. Anyway, I enlarged it to 13/16" with a hole punch, which nicely fits the conduit.


I modified a waterproof bulkhead angle conduit coupler and a wire gland to make the downfeed gland. I didn't want the gland facing up to reduce the chance of leaks. Also, there was not enough clearance between a vertical gland and the rack channel.


The downfeed assembled It still need lap sealant, but that will wait until the cable is run.




Next steps are to install and wire in the combiner box under the last panel, install that panel, shim the panels, and tighten 'em down.
