Non-Exporting DER Programs
Non-Exporting DER programs provide customers with options to generate and use solar energy for their own needs without exporting electricity to the distribution grid. The two main options are Self Generating Facility Zero-Export Solar Systems (SGF ZESS) and Micro-Solar Systems (MSS), each designed for a different purpose and capacity, subject to applicable technical and safety requirements.
SGF ZESS
Self-Generating Facility Zero-Export Solar Systems (SGF ZESS) are solar PV installations intended solely for a customer’s own use and has two classifications. A connected SGF ZESS is equipped with control or isolation mechanisms that prevent electricity from flowing back to the distribution grid, while an isolated SGF ZESS operates independently from the grid.
MSS
Micro Solar Systems (MSS) are small, consumer-grade, plug-and-play solar systems. They typically consist of solar PV modules and a micro-inverter that is connected through a standard household wall outlet or a PEC-compliant circuit. MSS are intended for small-scale applications, with a total PV capacity of up to 1 kWp.
