For solar-plus-storage—the pairing of solar photovoltaic (PV) and energy storage technologies—NLR researchers study and quantify the economic and grid impacts of distributed and utility-scale systems. Much of NLR's current energy storage research is informing solar-plus-storage analysis. Energy. 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. 7 gigawatts direct current (GWdc) of capacity in Q3 2025, a 20% increase from Q3 2024, a 49% increase from Q2 2025, and the third largest quarter for deployment in the industry's history. 80 billion in 2024 and is projected to reach USD 193. Market expansion is supported by rising electricity costs, growing consumer demand for decentralized. The distributed solar PV energy generation market is experiencing significant expansion, propelled by heightened climate change awareness, decreasing solar panel costs, favorable government incentives for renewable energy, and growing demand for energy independence across residential and commercial. The US Energy Storage Monitor is a quarterly publication of Wood Mackenzie Power & Renewables and the American Clean Power Association (ACP). Each quarter, new industry data is compiled into this report to provide the most comprehensive, timely analysis of energy storage in the US.
