Solar power is showing a nice pattern of gradual gains and is becoming quite competitive with fossil fuel. As much as conservatives complained about the bungling of Solyndra, the govt's general investment in multiple solar companies sparked the industry and made solar cheaper.
China's gov't jumped into the field also, creating a kind of solar "space race", which cranked up the rate of R&D. It's a good "fight". (China was later caught under-pricing their solar products to drive out foreign competitors, but that's another story. I took a nasty stock hit due to that.)
Thus, even though Solyndra was a lost battle, it seems Obama won the solar war. Over-focusing on the failures has made many conservatives miss the bigger picture.
Solyndra was a really cool idea: paint the roof white and use regularly spaced solar-collecting tubes. It was especially useful for low sun angles, resulting in fairly even power throughout all seasons . It just didn't pan out because flat panels eventually got fairly cheap due to flat panel R&D such that flat panel INefficiency at low sun angles mattered less.
