Panel Junction Boxes

One of my biggest peeves about the solar industry is the move to MC4 junction boxes. These boxes have the wires sealed and no access inside the j-box under the panel. In the marine environment I personally prefer a j-box with a terminal strip. It allows for easier paralleling of the panels and if installed correctly they last for a long time. I always try to find panels that do not ship with MC4 connections.

This Sun Wize panels ships with a standard j-box. Most DIY's do not own the proper crimp tool for crimping MC-4 solar connectors. If you buy a panel with MC-4's you'll either need to pay to have them terminated or pay to buy the proper crimping tool.
