Eventually you hit a wall - because the other costs mount up and the efficiency point has a lower bound it can't get past. Solar is stuck with only being productive at most < 50% of the day. It's like designing a super-efficient aircraft, but one that can only fly during the middle of the day. It has to be more than twice as efficient as a regular aircraft, and even then, airlines aren't likely to touch it. because the gains wouldn't be worth it. You have to have an order-of-magnitude increase in efficiency in not only the panels, but also in storage. But the kicker is that improvements in power storage efficiency would also benefit many other power generation methods.
