Slow, evolutionary cost reductions in the basic costs of solar cell. It was $100 a watt when I was in college, immediately it's $3.50. At the former price, it was only good for the deep buoys and sattelites, but today, we can power street signs from it, and it even makes financial sense for some residences.
The price of electricity relative to inflation also steers people in the solar direction.
The single most defining factor has been government subsidies and due incentives. The second most important factor is that the sun rises in the east and sets in the west. Everything else have been mostly mental gymnastics.
I'm sorry to seem so pessimistic, but there a short time ago haven't been any breakthroughs in that field.

Can Nanosolar really craft solar more cost rationalized than coal?
For 2 years, all I've heard is a lot of sermon, and no real proof that they're getting anywhere. There are a lot of other companies working on thin picture, it's just that not everyone brags like Nanosolar. My guess is that they're really having trouble next to some physical or...
How to build a solar panel ?
Google your exact question. Like the other guy said, there are so many types. You have need of more detail about if your looking for electricity or hot water or heat etc Are you conversation photovoltaic? Hot water solar panel? Some use concentrators, some use guiders. Some use eutectic chemicals. There's many ways to...
