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 (http://www.dsireusa.org/
) and I think we need to get off that model eventually, especially before the money dries up. I don't think that is possible until the modules themselves really come down in price.
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.
