"Supply Curves for Rooftop Solar PV-Generated Electricity for the United States" shows methods for comparing the relative costs of PV electricity capacity based on solar resources. The report estimates total avilable rooftop capacity potential of 661,000 megawatts and generating potential of 819,000,000 megawatt-hours.

The National Renewable Energy Laboratory has published "A Historical Analysis of Investment in Solar Energy Technologies (2000-2007)." This paper explores the private and public investment in solar energy and how it has fueled industry growth. It shows that investment in solar technologies increased at an annual rate of 145% from 2004 to 2007.

The report reviews the efficacy of existing laws and regulations to protect solar access for new and existing buildings and recommends specific measures to improve and ensure solar access for those planning to use solar energy systems on homes and commercial buildings.

Some states and utilities require installation of UEDS between PV power systems and the utility grid as a device to ensure line worker safety. However, eight states and many major utility companies have recognized that safety devices and features already part of all code-compliant PV systems make the UEDS redundant and have eliminated its requirement.
