The Fort Irwin, California, REM developed and coordinated a 1MW concentrated solar array through the Environmental Security Test Certification Program (ESTCP). The concentrated solar array system tracks the sun to optimize exposure, which increases the efficiency of normal roof top or stand-alone photovoltaic. This project will save Fort Irwin around 2.4M kWh per year at a value of $310,000 per year and equivalent 8,392 MBTU savings.
