Going Solar to Save Money?

Here's the full story. 

Pat Kennell's motivation for installing sun power in his home is typical of the solar industry's new customer: He did it to save money.
The retired police officer from Stony Point, New York, said his cost of energy per kilowatt hour will go from 20 cents with the local utility company to 13 cents with his new solar technology. And it didn't cost him anything to install. The firm Kennell worked with, SolarCity, offered him a lease program, where customers with long-term contracts can have the equipment installed and maintained for free. Rivals of SolarCity offer similar programs.
