While not a new technology, energy storage is rapidly gaining traction as a way to provide a stable and consistent supply of renewable energy to the grid. The energy storage system of most interest to solar PV producers is the battery energy storage system, or BESS. While only 2–3% of energy storage systems in the U.S. are BESS (most are
could alleviate this challenge by storing PV energy in excess of instantaneous load. b. Many utilities are discontinuing “net metering” policies and assigning much lower value to PV energy exported to the grid. Batteries allow the PV energy to be stored and discharged at a later time to displace a higher retail rate for electricity. 3.
With the rapid evolution of photovoltaic systems over the last few decades, the National Electrical Code (NEC) has been tasked with “keeping up” with new solar markets, equipment and system innovations, and fire
