Extreme Balance of System Hardware Cost Reduction

On September 1, 2011, DOE announced $42.4 million in funding over three years for the Extreme Balance of System Hardware Cost Reduction (BOS-X) funding opportunity. Part of the SunShot Systems Integration efforts, the following projects are actively working under this effort:


BOS-X projects are focused on research and development to reduce the cost of balance of system (BOS) hardware, making it inexpensive, safe, and highly reliable. BOS hardware includes all components used in solar power installation other than the module and power electronics, and represents a major opportunity to achieve significant cost reductions.


Under BOS-X, DOE is funding new components and system designs to overcome scientific, technological, and engineering barriers to achieving safe, very low-cost, high-reliability BOS hardware.
