Solar Soft Costs Reduction Strategies

An Initiative of the U.S. Climate Alliance

In December 2018, the U.S Climate Alliance and the National Association of State Energy Officials released the Solar Deployment Guidebook: A Resource for State and Local Governments, aimed at elevating crucial strategies and tools for state and local governments to reduce the non-hardware costs of solar development.

│ Background

Solar “soft costs” are the non-hardware costs associated with solar energy projects. Soft costs include permitting, interconnection, financing, installation and acquiring new customers. While solar hardware costs continue their rapid decline, soft costs now often make up as much as two thirds of total costs of a project. Reducing softs costs is therefore essential to continued progress in solar deployment and the creation of robust, self-sustaining markets for solar in the U.S.

In January 2018, the federal government enacted import tariffs on solar hardware components including cells and panels, which are forecast to increase the total cost of U.S. solar projects by about 10 percent and reduce installations by 11 percent nationwide. As a result, the tariffs may reduce installed solar capacity by 7.6 gigawatts over the next five years.

│ State Leadership to Date

Many U.S. Climate Alliance states have implemented strategies to support the deployment of solar and reduce soft costs. In one example, New York State, through the NY Sun program, has developed a “Guidebook for Local Governments” with information, tools, and step-by-step instructions to support local governments managing solar energy development in their communities.

│ U.S. Climate Alliance Collaboration

U.S. Climate Alliance states are acting to accelerate solar adoption and soften the impact of the federal solar tariff by collaborating on characterizing and lowering solar soft costs. States are working together to develop a national solar-ready community guidebook to support solar deployment and reduce costs. The guidebook will synthesize existing solar market best practices and lessons learned, provide sample policy and program frameworks, and identify additional key state, federal, and private resources. The guidebook will further provide implementation tools to assist local governments with permitting and inspection, siting, zoning, property taxes, and solar procurement by municipalities. States are planning to deliver the guidebook in the fall of 2018.



To assist states and localities in accelerating solar adoption, The United States Climate Alliance (USCA) partnered with the National Association of State Energy Officials (NASEO) to elevate crucial strategies and tools for state and local governments to reduce the non-hardware costs of solar development. This Guidebook was written for state and local governments to identify gaps and opportunities for innovation in local solar market design; provide sample local policy and program frameworks, applications, and language; include local solar policy decision making considerations and planning scenarios; and point states and localities to additional state, federal, and private resources.
