Crunching Solar Numbers: The Big Apple Uses Big Data

The City University of New York (CUNY) and its partners developed an analytics-based approach that makes it easier to spot key solar market indicators such as new permit applications and photovoltaic (PV) installations as they happen in the city. Through the Energy Department's SunShot Rooftop Solar Challenge, the CUNY-led team is launching an advanced analytics portal that helps community leaders look at solar data in a new light.

The Long Island Solar Farm

In November 2011, a utility-scale solar array became operational in the most unlikely of places: at Brookhaven National Laboratory on densely populated Long Island, New York. Now the largest utility-scale solar power plant in the eastern United States, the Long Island Solar Farm is a remarkable success story whereby very different interest groups capitalized on unusual circumstances to develop a mutually beneficial source of renewable energy.

Overcoming Solar Roadblocks: There's a Map for That

Optony, through the Southwest Solar Transformation Initiative (SSTI), successfully launched their Solar Roadmap with support from the U.S. Department of Energy's Rooftop Solar Challenge. This customizable, interactive web platform, which shows the real-time status of the solar market in more than 70 participating jurisdictions, makes it easier and more cost-effective for residents to obtain clean, locally produced power with solar energy installations.

Model Interconnection Procedures

IREC first developed Model Interconnection Procedures in 2005 in an effort to capture emerging best practices in this vital area. Several important evolutions in best practices are synthesized into the 2013 Model Interconnection Procedures, last updated in 2009.

The important advances incorporated into these model procedures include:

Financing U.S. Renewable Energy Projects Through Public Capital Vehicles: Qualitative and Quantitative Benefits

This paper explores the possibility of financing renewable energy projects through raising capital in the public markets. It gives an overview of the size, structure, and benefits of public capital markets, as well as showing how renewable energy projects might take advantage of this source of new funds to lower the cost of electricity.

Strategic Sequencing for State Distributed PV Policies

State and local policymakers show increasing interest in spurring the development of customer-sited distributed generation (DG), in particular solar photovoltaic (PV) markets. Prompted by that interest, this analysis examines the use of state policy as a tool to support the development of a robust private investment market. This analysis builds on previous studies that focus on government subsidies to reduce installation costs of individual projects and provides an evaluation of the impacts of policies on stimulating private market development.

Powering Your Community With Solar: Overcoming Market and Implementation Barriers (Fact Sheet)

This document introduces the Energy Department's new Solarize Guidebook: A Community Guide to Collective Purchasing of Residential PV Systems. The guide is designed for 'green' consumers, utilities, local governments, and community groups who want to replicate the success of the Solarize Portland model, overcome barriers to implementation, and permanently transform the market for solar energy in their communities.

Increasing Community Access to Solar: Designing and Developing a Shared Solar Photovoltaic System (Fact Sheet)

This document introduces the Energy Department's new Guide to Community Shared Solar: Utility, Private, and Nonprofit Project Development. The guide is designed to help those who want to develop community shared solar projects - from community organizers and advocates to utility managers and government officials - navigate the process of developing shared systems, from early planning to implementation.

Funding Solar Projects at Federal Agencies: Mechanisms and Selection Criteria (Brochure)

Implementing solar energy projects at federal facilities is a process. The project planning phase of the process includes determining goals, building a team, determining site feasibility and selecting the appropriate project funding tool. This fact sheet gives practical guidance to assist decision-makers with understanding and selecting the funding tool that would best address their site goals.
