You must not have read any of the case studies at the site I linked (which came from your post), and that's not even a recently updated site.
From a business standpoint, solar power devices will simply not keep being installed if they haven't proven cost effective. The market has proven they do have a place as a supplemental or alternative power source.
Reality is flying in the face of your statements, yet you choose to keep plodding along with your mindset.

Incorrect. Tax subsidies hide almost the entire cost from the consumer. Please review this link from the article: Financial Incentives for Solar Energy
