New Berkeley Lab study analyzes the financial performance of Connecticut solar leasing program that targets low- and moderate-income customers


Policymakers are increasingly interested in how to expand access to rooftop photovoltaic systems.

New Berkeley Lab Report Looks at How Low- and Moderate-Income Solar Programs are Evaluated


Over 40 programs seek to bring solar to low-income households, but with varying levels of evaluation

New Berkeley Lab report on solar-adopter income trends


new report by Lawrence Berkeley National Laboratory highlights income, demographic, and other socio-economic trends among U.S. residential rooftop solar adopters.

New Berkeley Lab Report Documents Trends in System Impacts, Reliability and Market Value of Solar in the United States


With continued deployment of solar across the United States, assessing the interactions of solar with the power system is increasingly important. Impacts of solar on the bulk power system are obvious in the CAISO system, including changes to the net load, wholesale prices, and the market value of solar. The same impacts are not seen in ISOs with much lower penetrations of solar.

Berkeley Lab releases updated distributed solar dataset


New data illustrates trends in distributed solar pricing and design trends

We are pleased to announce the release of Berkeley Lab’s Distributed Solar 2020 Data Update. These data are available in the form of a public data file, interactive data visualizations, a graphical slide deck summary, and summary data tables.

Berkeley Lab webinar: Comparative trends in utility-scale wind and solar markets in the United States


Please join us on Tuesday, December 8, at 10:00 AM Pacific / 1:00 PM Eastern time for a free webinar presenting highlights from Berkeley Lab’s 2020 utility-scale wind and solar data updates.

New data compilation illustrates the continued growth and declining cost of utility-scale solar


We are pleased to announce the release of Lawrence Berkeley National Laboratory’s 2020 Utility-Scale Solar Data Update. The release provides an updated overview of data and trends in ground-mounted solar projects in the United States that are larger than 5 MWAC, in the form of a comprehensive data file, a briefing slide deck summarizing select insights, and a series of data visualizations.

Berkeley Lab study explores measures to increase solar adoption equity


Low- and moderate (LMI) income households are less likely than high-income households to adopt rooftop solar photovoltaics in the United States, though policy-makers and others in the industry have increasingly sought out strategies for addressing this inequity.

Berkeley Lab report evaluates utility-owned rooftop solar


The rapid growth of rooftop solar photovoltaic (PV) systems can pose a number of financial challenges for both electric utility shareholders and their customers. One potential pathway to resolving those concerns involves allowing utilities to own and operate rooftop solar systems. However, the financial impacts of this business model are not well understood.

Interest in Hybrid and Co-Located Power Plants Continues to Grow


New data compilation from Berkeley Lab tracks existing and proposed projects

As battery prices fall and wind and solar generation rises, power plant developers are increasingly combining wind and solar projects with on-site batteries, creating “hybrid” power plants. But hybrid or co-located plants have been part of the U.S. electricity mix for decades, with widely ranging configurations that extend beyond pairing a generator with a battery.

New research assesses fleet-wide performance of utility-scale PV in the United States, and how it has changed with age


Berkeley Lab is pleased to announce a new article recently published in the Journal of Renewable and Sustainable Energy, titled “System-Level Performance and Degradation of 21 GWDC of Utility-Scale PV Plants in the United States.” This study finds that first-year performance generally lives up to ex ante expectations, while the rate of performance decline over time depends on factors such as plant vinta

New study finds solar PV permitting timelines are getting shorter, but customers still face significant uncertainty


Local permitting timelines for rooftop solar systems are getting shorter but remain highly variable, according to a new Berkeley Lab study published in the journal Energy Policy. Most PV permitting processes take fewer than 2 months from permit application to a passed inspection, but some customers face substantially longer timelines. The differences in permitting authority experience and policies explain some of this variation.



New study finds increase in expected useful life and decrease in operating expenses over time for utility-scale PV


Solar professionals report that the assumed useful life of PV projects now exceeds 30 years in most cases, with OpEx dropping by 50% over the last decade.

New Berkeley Lab report on solar-adopter income trends


A new report by Lawrence Berkeley National Laboratory highlights income trends among residential rooftop solar adopters.

Latest Grid Data Book Reveals Key Trends in Renewable Integration


Biennial Data Compilation Identifies Changes in Markets and Power System Operations as Renewables Are Integrated onto the Grid

The share of variable renewable energy (VRE)—mainly solar and wind—generation on U.S. regional power systems more than doubled on average from 2012 to 2018, according to the newly released 2018 Renewable Energy Grid Integration Data Book.

Berkeley Lab’s “Utility-Scale Solar” report sees continued growth and falling costs for big solar


We are pleased to release the 2019 edition of Berkeley Lab’s Utility-Scale Solar report, which presents analysis of empirical project-level data from the U.S. fleet of ground-mounted photovoltaic (PV) and concentrating solar-thermal power (CSP) projects with capacities exceeding 5 MWAC.

Distributed Solar Prices Continue to Fall as Systems Become Larger and More Efficient


The latest edition of Lawrence Berkeley National Lab’s annual Tracking the Sun report finds that prices for distributed solar power systems continued to fall in 2018, that industry practices continue to evolve, and that systems are getting bigger and more efficient.

New report develops simple methods to explore the resource adequacy contribution of solar and storage


Resource adequacy contribution of solar and storage depends on the configuration

We are pleased to announce the publication of a new report titled “Drivers of the Resource Adequacy Contribution of Solar and Storage for Florida Municipal Utilities.” This report describes relatively simple methods for estimating the resource adequacy contribution of solar and storage. Simple methods can be useful for many utilities and regions addressing similar questions prior to evaluation of specific cases that require more detailed and resource-intensive modeling.

New report finds attractive wind energy prices, at under 2¢/kWh on average


Annual DOE Report Finds that Wind Energy Is Being Sold at Record-Low Prices

We are pleased to announce the release of the U.S. Department of Energy (DOE)’s “2018 Wind Technologies Market Report,” which provides an annual overview of trends in the U.S. wind power market.

Student capstone papers yield new insights into solar market dynamics


Summary of UT Austin Student Capstone Projects

We are pleased to release a summary of the key findings from seven different papers completed by teams of University of Texas (UT) at Austin students, each of which explored a different aspect of the solar market.
