%T Tracking the Sun: Pricing and Design Trends for Distributed Photovoltaic Systems in the United States, 2023 Edition
%8 09/2023
%X <p>Berkeley Lab’s annual <em>Tracking the Sun</em> 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.&nbsp; Ground-mounted systems larger than 5 MW-AC are covered in Berkeley Lab’s companion annual report, <a href="https://emp.lbl.gov/utility-scale-solar/"><em>Utility-Scale Solar</em></a>.</p><p>The latest edition of the report is based on 3.2 million systems installed through year-end 2022, representing more than 80% of systems installed to date. The report describes and discusses key trends related to:</p><ul><li><strong>Project characteristics</strong>, 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</li><li><strong>Median installed-price trends</strong>, both nationally and by state</li><li><strong>Variability in pricing</strong> according to system size, state, installer, equipment type, and other factors, relying on both descriptive and econometric analysis</li></ul><p>The report also includes a multi-variate regression analysis to estimate the effects of key pricing drivers for residential systems installed in 2022.</p>
