When Will Solar Be Cost-Competitive with Electricity?

Comparing silicon crystaline solar panels with thin film is not as simple as you make it out to be. Cost per watt is not the primary driving factor in purchasing solar panels for your roof for example. What you want it the most watts per square foot, and for that, conventional panels beat thin film two to one. Where space is less limited, thin film may be the better choice.

I have read that solar thermal is the cheapest form of solar energy at present. And solar thermal plants can store heat and produce electricity at night.
