1. Solder does not break down due to UV.
2. The lead in lead-tin solder will react with moisture to form a white
crumbly oxide. Exposed to the elements, the entire joint will
eventually become porous and brittle. That's why plumbing solder is
lead-free, and that is what I use (otherwise unprotected) for all my
outdoor solder connections.
