45% efficiency is a 12.5% improvement over 40% efficiency - that is quite a big deal. In sunny climes like So Cal, a house with its roof covered in these could probably stay off the grid year-round.

Even with a medium size roof and the inefficient panels available today, people can generate more electricity with solar than they consume... So no need to wait for more efficient panels! I'm in Southern California and am in the process of choosing a solar installer, and it appears it will be no problem zeroing out my electric bill.
