SEIA produces a variety of research and supporting resources for the solar industry, ranging from full reports to short factsheets. This data helps inform policymakers and business leaders alike on the current state of solar and where the industry is headed.

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.

Utility External Disconnect Switch Report

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.
