I think the greatest expense and headache is the storage batteries. They require maintainence and do not last as long as the panels.

I can see how that would be the case, most of the other stuff is solid state, and if it is in a dry, properly maintained environment with the wiring properly done, most of the other stuff would likely last a while.

So, yeah...that makes sense to me.
