"For right now, thin film’s great for commercial jobs with huge amounts of space, for residential, silicon panels are the way to go."

Not very good at math, I see. The difference in space needed for 14% efficient cells vs 22% efficient cells simply isn't that great, considering that the 14% efficient cells cost ~1/4 as much as the 22% cells. If you were talking about using them to power a comsat, you might have a case, but for rooftop use.....no.
