High Penetration Solar Portal

The High Penetration Solar Portal has timely information related to high penetration solar scenarios and integrating solar into the grid. The site allows utilities, grant awardees, regulators, researchers, and other solar professionals can easily share data, case studies, lessons learned, and demonstration project findings.

Through the SunShot Initiative, the U.S. Department of Energy (DOE) supports the development of innovative, cost-effective solutions that allow increasing amounts of solar energy to integrate seamlessly with the national power grid while mitigating associated risks and reducing system costs. Such solutions will help achieve the SunShot goals by ensuring system reliability and encouraging the widespread deployment of solar technologies, such as photovoltaics and concentrating solar power.

Research, Development, and Demonstration

DOE, through the SunShot Systems Integration activities, focuses on research, development, and demonstration to achieve the SunShot goals through reducing the cost of power electronics and balance of system components, reducing project risks and increasing project bankability, and developing technologies and strategies that enable high penetrations of solar electricity on the national power grid.

Competitive Awards

Within the Systems Integration activities, DOE provides funding, through competitive awards, to a range of research and development projects. In addition to projects that advance balance of system hardware technologies such as racking systems and power electronics, DOE funds projects to address the technical challenges associated with integrating high penetrations of solar electricity into the grid.
