united states – Affordable Solar Power, Creating Renewable Energy with Solar Panels

Who is the leader in manufactering solar panels in the United States?

I think the question pretty much explains itself. I’m looking for the leader and hopefully who’s the best in commerical and private solar panels.

Is it possible to power the whole United States by solar power?

I saw a movie at school a while ago that said we could power the whole united states if we made a certain state all solar power (I can’t remember which state). Also how many watts does the united states use that way i can calculate how many solar panels would be needed.

How long before all homes in America have solar panels enabling us to sell power back to the providers?

It would be great to have an electric meter that ran both ways. Thereby only allowing the electric companies to charge us for the power we did not compensate for by solar power.
