State Clean Energy Policies Analysis: State, Utility, and Municipal Loan Programs

This report relies on six in-depth interviews with loan program administrators to provide descriptions of existing programs. Findings from the interviews are combined with a review of relevant literature to elicit best practices and lessons learned from existing loan programs. Data collected from each of the loan programs profiled are used to quantify the impacts of these specific loan programs on the commonly cited, overarching state clean energy goals of energy security, economic development, and environmental protection.

Massachusetts: The Next Hot Solar Market?

Following in the footsteps of states like New Jersey, Pennsylvania, and Maryland, Massachusetts is about to implement a Renewable Portfolio Standard (RPS) solar requirement. Like other solar RPS states, Massachusetts will spark solar demand by creating a market for Solar Renewable Energy Credits (SRECs), each of which represents one megawatt-hour of solar electricity generation.

Inspector Guidelines for PV Systems

Guidelines included in this report form a framework for inspecting and permitting PV systems. Guidelines are divided into two stages: plan checking and field inspection. The objective of these guidelines is to facilitate the installation of safe PV systems at minimal cost.

Solar Photovoltaic Financing: Residential Sector Deployment

This report presents the information that homeowners and policy makers need to facilitate PV financing at the residential level. The full range of cash payments, bill savings, and tax incentives is covered, as well as potentially available solar attribute payments. Traditional financing is also compared to innovative solutions, many of which are borrowed from the commercial sector.

Green Power Marketing in the United States: A Status Report (11th Edition)

This report documents green power marketing activities and trends in the United States, focusing on consumer decisions to purchase electricity supplied from renewable energy sources.

Utility-Interconnected Photovoltaic Systems: Evaluating the Rationale for the Utility-Accessible External Disconnect Switch

This report examines the utility-accessible external disconnect switch debate in the context of utility-interactive PV systems for residential and small commercial PV installations. It focuses on safety, reliability, and cost implications of requiring an external disconnect switch.

Feed-in Tariff Policy: Design, Implementation, and RPS Policy Interactions

This report explores the design and implementation of feed-in tariff policies, including a policy definition, various payment structures, and payment differentiation options. The report also discusses the interaction between FIT and RPS policies.

The Impacts of Commercial Electric Utility Rate Structure Elements on the Economics of Photovoltaic Systems

This analysis uses simulated building data, simulated solar photovoltaic (PV) data, and actual electric utility tariff data from 25 cities to better understand the impacts of different commercial rate structures on the value of solar PV systems. By analyzing and comparing 55 unique rate structures across the United States, this study seeks to identify the rate components that have the greatest effect on the value of PV systems.

Solar Leasing for Residential Photovoltaic Systems

This publication examines the solar lease option for residential PV systems and describes two solar lease programs already in place. As a result of the $2,000 cap on the residential ITC being lifted in 2009, the expansion of the solar lease model across the United States may be slower than anticipated. The lease model, though, still offers homeowners some distinct advantages. This publication helps homeowners revisit the comparison between the solar lease and home-equity financing in light of the change to the ITC.

Power Purchase Agreement Checklist for State and Local Governments

This fact sheet addresses the financial, logistical, and legal questions relevant to implementing PPAs for PV installations.
