SunShot Initiative

Chosen by the U.S. Department of Energy in December 2011 as one of 22 regional teams nationwide, the Diablo Innovation Alliance is leading a local effort to develop innovative solutions that will dramatically accelerate market adoption of rooftop solar photovoltaic (PV) energy systems by addressing key market barriers in the following four action areas:


The Rooftop Solar Challenge is part of the DOE SunShot Initiative, which seeks to reduce the costs of installing residential and small commercial solar PV systems so that solar energy is cost-competitive with other forms of energy by the end of the decade. By addressing the four action areas noted above, the DIA will clear a path for rapid expansion of solar energy and serve as a model for other communities across the nation. Aggressively driving innovation, the DOE is supporting efforts to reduce the cost of solar so that it can achieve grid parity and thus enhance the nation's energy security and reduce greenhouse gas emissions while supporting economic growth and job creation.

The DIA is working with local building officials from eight jurisdictions within Contra Costa County—including the county and the cities of Antioch, Brentwood, Concord, Martinez, Oakley, San Ramon, and Walnut Creek—and other participants including the California Solar Energy Industries Association (CALSEIA), local solar contractors, PG&E, and financial institutions, to develop model processes and practices in the four action areas that can be rapidly deployed and scaled up statewide.
