Interesting article on the solar panels, I don't like to be a conspiracy theorist, but it sounds a bit suspect for me. I don't doubt there are issues as claimed, but they appear to be suggesting they're very difficult or insurmountable to solve, which seems a little convenient.
The rate energy costs are rising, it won't be long at all before solar is competitive, and this certainly sounds like one way energy companies can slow down the transition. Might be a good short opportunity in the near future (energy companies that refuse to adapt).
