"In response to public interest in customer-sited distributed solar photovoltaics (PV), state and local policymakers have implemented policy initiatives with the goal of encouraging private investment and building a robust PV market. Policymakers face challenges, including limited budgets and incomplete information about the effectiveness of the various policy options in their specific situation and in crafting and executing policy that supports market development goals.

This paper builds on [earlier] research to determine the most effective policy strategies for different types of states, as determined by their physical, demographic and macroeconomic context."
