Small wood frame finishing

I am planning to make a wood frame for a solar panel so it needs to be completely waterproof.

Does anyone have any good ideas for waterproofing that will last forever? And be super water tight. I mean, I can't let any water into this thing or else the metal on the solar cells will corrode.

I read somewhere on this forum, someone suggested covering the wood in plastic. How exactly would I go about doing that?

The only thing I can think of that lasts forever is death and taxes. A coating for wood exposed to the elements creating a film finish would be a marine spar varnish applied in many coats. But, even that would need regular maintenance to be effective.

You might consider making the frame out of a waterproof material like a plastic material, or PVC, Plexiglas, etc. Materials like that are pretty much maintenance free.

If you allow enough space for the cloth you can fiberglass the frame and it will last like a boat. For maintenance every five years put another coat of resin on it.
