Local Renewable Energy: Solar
PV Watts Calculator
NREL's PVWatts™ calculator determines the energy production and cost savings of grid-connected photovoltaic (PV) energy systems throughout the world. It allows homeowners, installers, manufacturers, and researchers to easily develop estimates of the performance of hypothetical PV installations.
Solar Energy Resources for Government Officials
The U.S. Department of Energy's Solar Energy Technologies Office offers resources for state and local government officials.
Solar Power Purchase Agreements
A Solar Power Purchase Agreement (SPPA) is a financial arrangement in which a third-party developer owns, operates, and maintains a photovoltaic (PV) system, and a customer hosts the system on its property and purchases the system's electric output for a predetermined period. EPA's Green Power Partnership provides information on SPPAs, including how they are structured, and the benefits and challenges of implementing them.
A Guide to Community Solar
The U.S. Department of Energy’s online publication A Guide to Community Solar is designed as a resource for those who want to develop community solar projects, from community organizers or solar energy advocates to government officials or utility managers.
Toolbox for Renewable Energy Project Development
EPA's Green Power Partnership is working with stakeholders to identify economic and administrative barriers in the deployment of on-site renewable energy projects. The toolbox website examines six key issues that have important implications for developing on-site solar projects, identifies key resources, and addresses major questions and hurdles sustainability experts have identified as information gaps or obstacles in their development of new on-site solar projects.
Local Government Solar Project Portal
Local governments will find project development resources and learn from industry experts and their peers.
Installed Price of Photovoltaics in the U.S.
Tracking the Sun: The Installed Price of Residential and Non-Residential Photovoltaic Systems in the United States summarizes trends in the installed price of grid-connected PV systems in the United States.
