SunShot Prize to Cut Solar Installation Costs

SunShot Prize: Race to the Rooftops

Sponsored by the U.S. Department of Energy (DOE), the SunShot Prize aims to spur low-cost rooftop solar installations across the nation. This competition offers a total of up to $10 million in cash awards to the first three teams that repeatedly demonstrate an average of $1 per watt (W) for non-hardware costs such as permitting, interconnection, and inspection.

Despite unprecedented cost reductions for solar hardware over recent years, as much as 50% of the total cost for residential and small-commercial photovoltaic (PV) systems is related to the price to plug in. Enabling dramatic reductions in the non-hardware costs—or "soft costs"—of solar is now the greatest challenge to achieving cost-competitive solar by 2020.

The SunShot Prize directs the efforts of solar innovators at solving the soft cost challenge. Winning teams will successfully deploy 5,000 small-scale (2–15 kilowatt) rooftop PV systems with non-hardware costs averaging $1/W during Phase I of the competition. Phase II, which is intended to assess business sustainability of the winning teams, calls for the installation of an additional 1,000 qualifying systems.  Details at
