J-Boxes? Waterproof? Where to Buy?

Hey all,

I am looking for a source of various junction boxes for the newly build semi-flexible panels for my install. We'd like to try various configurations and try to figure out which one is the most watertight and wind/sun resistant for the roof of an RV.

Smaller is better. They should allow for around 8 amps or so at 24V

Thanks,

Rich

    You really don't want waterproof ones. What happens is that they get cold at night and moisture condenses internally, and has no way to get out. It is almost impossible to get them totally airtight, so over time the water will build up inside.
