The Solar Technology Acceleration Center (SolarTAC) is an integrated, world-class test facility where the solar industry can research, test, validate, and demonstrate solar technologies. SolarTAC’s mission is to provide a world-class test and demonstration facility where members can perform proprietary and collaborative research, development and demonstration activities that accelerate solar technology.

Located near Denver International Airport in Aurora, Colorado, the 74-acre SolarTAC site offers flat, graded topography and excellent insolation conditions with over 300 days of sunshine a year in one of the most progressive renewable energy states in the country.

The SolarTAC site will include facilities for testing both photovoltaic and concentrated solar power (CSP) technologies, including access to the grid.
