Berkeley Lab’s annual Tracking the Sun report describes trends among grid-connected, distributed solar photovoltaic (PV) systems in the United States. The latest edition of the report focuses on systems installed through year-end 2021, and is based on data from roughly 2.5 million systems. New to the report this year is an expanded coverage of paired PV-plus-storage systems, including details on system design and pricing trends.
The report describes trends related to:
- Project characteristics, including system size, module efficiencies, prevalence of paired PV with storage, use of module-level power electronics, third-party ownership, mounting configurations, panel orientation, and non-residential customer segmentation ownership
- Median installed-price trends, both nationally and by state, including preliminary data for first half of 2022
- Variability in pricing according to system size, state, installer, equipment type, and other factors, relying on both descriptive and econometric analysis.
