RESEARCH: Tracking the Sun by Berkeley Lab

Berkeley Lab’s annual Tracking the Sun report describes trends among grid-connected, distributed solar photovoltaic (PV) and paired PV+storage systems in the United States. For the purpose of this report, distributed solar includes residential systems, roof-mounted non-residential systems, and ground-mounted systems up to 5 MW-AC.  Ground-mounted systems larger than 5 MW-AC are covered in Berkeley Lab’s companion annual report, Utility-Scale Solar.  The latest edition of the report is based on 3.7 million systems installed through year-end 2023, representing roughly 80% of systems installed to date. Tracking the Sun | Energy Markets & Policy (lbl.gov)
