Depends of what part of the country you are in and what kind of rebates and incentives are available. Joe Solar up in Alaska will probably have a harder time than someone in New Jersey, Arizona or California. Solar installatioins have steadily increased over the last few years but we can do better.
This industry is incentive driven (

Ontario, Canada is enjoying a boom in solar because of a very lucrative microFiT program, the same type that Germany has had for 5 years. FiTs are a great way to encourage people to install solar as long as the program can sustain itself. Spain, for example, showed us how to run a FiT program, and how not to run one.
