Word up. Solar is still not ready for prime time given the costs/savings. I'll wait for the 5X efficiencies noted in the article.
I do think it'll be workable someday.
You may have quite a while to wait, the efficiencies mentioned in the article are fictitious. To come up with that 5x number, they first pretended that the current crop of solar cells were 2.5x less efficient than they actually are. And then they fudged up their own efficiency by quoting the level they "expected" to eventually achieve, rather than the level currently obtainable. (source)
