Efficiency is not what is under discussion.

Yes it is. Industry records show that efficiency helps solar make people money after eight years (while non-solar users still lose money).

Only if those "solar people" are not paying the actual lifetime costs of the installation. When will you "get" that basic fact?

After eight years, everything is profit. Whether "lifetime" or not.

This is well-known within the solar power industry. You do not "get" this basic fact.
