The NREL study models market penetration of rooftop photovoltaics in the United States in a variety of scenarios and on a state-by-state basis for years 2007 to 2015. The report found significant potential for rooftop solar in the United States in terms of potential cumulative installations and contributions to future...

The NREL report analyzes soft cost reduction trajectories, and compares those with the cost-reduction goals of the US Department of Energy’s SunShot Initiative. The report found that at both residential and commercial scales, the current trajectory case does not achieve US DOE SunShot Targets by 2020.

This North Carolina Solar Center and Meister Consultants reports addresses uncertainty over how PV systems should be valued and tax for property tax purposes.  The report assesses property taxes as they apply to solar PV systems and how systems are assessed under PV-specific and general property tax laws. The report...

This paper explores the feasiblity of extending the Real Estate Investment Trust (REIT) model to solar projects. Just as REITs have spurred investment into commercial real estate, Solar-REITS (S-REITs) could open up solar projects to small investors, increasing capital flows into solar energy markets. The income...
