That prices of these cleaner forms of energy are falling so far and so fast has a lot to do with global manufacturing scaling up, financial markets getting smarter, local government better understand the technology, large scale utility installations investing in research and more factors after that. And more importantly that all of those factors – are that everyday people accept and want solar power as part of their energy mix.

Interestingly, these projections from Swanson have actually been underestimating the fall in price of solar. Expect more price drops to occur – but also expect incentives to fall.
