White zip ties are for tying up the bag of shop garbage.

If you can find them (Fastenal, etc.) we prefer metal barbed, black UV resistant zip ties. Also, a "flush cut" dykes/diagonal cutter (Knipex is my favorite) is a must for getting the tails of the zip ties cut flush with the cinch end to avoid sharp ends.

Weatherpak connectors, buss bars, and weatherproof labeling will make your life much easier.
