The price of solar power in the United States keeps dropping. Back in 2008, the cost of installing a rooftop solar system was about $8 per watt. Today, it’s about half that — and still falling.

Up until 2012, that price decline was largely due to the fact that the photovoltaic panels themselves were getting cheaper, driven by a glut of Chinese manufacturing and various technology improvements. This story got a lot of attention in the press.
