Guide to Solar Incentives in America's 12 Biggest Cities



Uncle Sam and many state and local governments and utilities offer financial incentives to homeowners who install a solar power system. The federal Residential Renewable Energy Tax Credit will reduce your federal income tax bill dollar for dollar for 30% of the up-front cost of a system (the system must be in service by December 31, 2016). States may also offer a tax credit, and states and cities often offer rebates as well as sales and property tax exemptions.

We asked, which provides comparisons of estimates from solar-panel installers, to estimate the size and cost—before and after incentives—of a solar power system that would cover a $100 monthly electricity bill in America's 12 biggest cities. (If you use more than that, you will have to buy electricity directly from your electric utility to cover the excess.) The site also estimated annual and total savings for both a purchased system and one leased over 20 years, plus the payback period—that is, how long it would take to recoup the up-front cost of a solar power system.


In most areas, homeowners can get credit for any excess electricity that their system produces (called net metering). That credit is baked into the estimated monthly and annual savings.
