Is solar power a good cap and trade play?

The darling of the green revolution?

Yesterday, a MadMoney caller asked Jim Cramer why most solar stocks have been tanking recently, even as cap and trade moves closer and closer to becoming law. Because solar power simply isn't viable without massive government incentives, even if cap and trade becomes law, replied Cramer.

I don't know if Cramer is right, but I was pretty shocked to hear Cramer's response. Kind of makes one wonder if solar power is really a good green investment, or whether solar power is just a good hedge against oil prices.
