Probably cheaper energy, and also perhaps a different subsidy/regulatory environment. I know in California, the utilities are fighting to make solar users pay more than they currently do, saying the solar customers don't pay their fair share of distribution and transmission costs. Also, as a former leased-solar customer, there are some downsides. Having solar in my area adds a few thousand dollars to a roof replacement. Furthermore, solar panels are sort of an acquired taste, aesthetically speaking. When I had solar, it was nearly a wash in terms of how much I saved vs how much I paid monthly to SunRun, the company I leased them from. It did allow me to run my air conditioner nearly all the time because I was incentivized to use the power I generated, but it also meant I had a loud box outside my bedroom window and the clicking of the relays woke me up many mornings.
