Hmmm...
You post an article showing dropping sales and state the tech will never work.
Then you state several posts into the thread that you have solar installed on your roof and are at the break even point.
People that argue with themselves like this are usually the same kind of kooks still living off the Y2K supplies stored in their bomb shelters.
Have you actually been to Japan? Few Japanese actually have a roof of their own. Those that do, do not have a lot of surface area.
I would like to have a system of my own, but here in Minnesota high sun days are rare and power from the grid is still pretty cheap.
