Everyone and their brother are jumping on the PV solar cell bandwagon, which is good for consumers, but I can't see it being all the profitable for most of these firms. 

Is Intel using proprietary PV cell tech, or leasing other's? Some cells are more efficient than others. Some are much better than others, and thus command and a premium. 

I find it ironic the solar plant is in Oregon. I bet that 50 mil Intel spent, was more than offset by the massive tax breaks from state of OR, and their 'green' love fest.

per year?

per month?
