I'm not regurgitating anything. I'm looking at how much electricity my panels generate, and what percentage of it I use, and I can say definitively that it would not make financial sense for me if not for the feed-in tariff program that pays me a guaranteed rate for electricity I sell back to the grid.

You can't just blindly say "PVs save you money". It matters very much how much sunlight you get, the orientation of your roof, how much electricity costs, how much labor and installation costs, etc.

My location is far from ideal for solar. But with incentives - which are funded in my country via a per-kWh surcharge on everyone's electricity bills - it just barely makes financial sense to have solar panels on my roof.
