China is one of the leading producers of solar panels at exceptionally cheap prices. China and the Philippines are currently in a bit of a sour mood with each other. The US could step in with cheap solar panels if they were researching that, but alas, who do you think is going to be providing them with cheap LNG?
So while the story indicates that solar is at it's cheapest it's ever been. Not for the Philippines. The Philippines is a clear cut example of how the United State's continued resistance to a domestic solar panel production industry is literally hurting their long term prospects. There's a lot of nations out there that want panels and right now, China is the only serious game.
