And how much of that is a direct result of the fact they are competing against Chinese-made panels that are directly funded by the Chinese government?
There is literally no way you can have a discussion about ANY renewable energy without it being political. Either the US is going to protect US industry from Chinese goods being sold below-cost, or we're going to have to do the same thing to compete.
You're assuming the politicians have the area's best interest at heart. Start by thinking - what's in it for them? Good press for bringing in a nationally recognized brand to the area. Maybe campaign contributions from said company. Maybe you get thrown some more campaign contributions from the construction companies that get work out of the deal.
Keep in mind the opportunity cost for these deals. Cut the company a tax break, or continue to not collect taxes on a vacant lot. If Buffalo actually brought cash to the table... that was quite a gamble.
