A recent NREL report finds that in 2011, 17% of U.S supermarkets were in utility territories where PV could be installed at or below the cost of traditional generation. In 2012, they estimate that this percentage increased to 40%. The report is

The National Renewable Energy Laboratory (NREL) routinely estimates the technical potential of specific renewable electricity generation technologies.
At high penetration of solar generation there are a number of challenges to economically integrating this variable and uncertain resource.
Concentrating solar power (CSP) deployed with thermal energy storage (TES) provides a dispatchable source of renewable energy.
Establishing interconnection to the grid is a recognized barrier to the deployment of distributed energy generation. This report compares interconnection processes for photovoltaic projects in California and Germany.
To stimulate investment in renewable energy generation projects, the federal government developed a series of support structures that reduce taxes for eligible investors--the investment tax credit, the production tax credit, and accelerated depre
Utility-scale solar projects have grown rapidly in number and size over the last few years, driven in part by strong renewable portfolio standards (RPS) and federal incentives designed to stimulate investment in renewable energy technologies.
More than half of the electricity produced in the southeastern states is fuelled by coal. Although the region produces some coal, most of the states depend heavily on coal imports.
Technical concerns with integrating higher penetrations of photovoltaic (PV) systems include grid stability, voltage regulation, power quality (voltage rise, sags, flicker, and frequency fluctuations), and protection and coordination.
