GM-SEUS 2025: Ground-Mounted Solar Arrays and Panel-Rows in the United States

A 2025 release, the GM-SEUS v2.0 dataset contains 18,980 commercial- and utility-scale ground-mounted solar arrays across the United States, representing 292 GW of capacity. Created by Jacob Stid and published on figshare, it harmonizes open-access data with image analysis to provide detailed geometries and attributes for arrays and panel-rows.

Use Cases

• Model renewable energy generation potential based on array capacity and location data.
• Assess land-use impact and ecosystem services based on array area and ground cover ratio.
• Plan infrastructure and grid integration based on installation year and array technology attributes.
• Analyze solar farm design and efficiency based on panel-row geometries, tilt, and inter-row spacing.

Strengths

• Includes 18,980 solar arrays with a total capacity of 292 GW and area of 3,817 km².
• Provides detailed panel-row geometries for 12,739 arrays, comprising 3.43 million unique rows.
• Harmonizes value-added attributes like installation year, azimuth, tilt, and ground cover ratio from multiple sources.
• A subset of 15,744 arrays is verifiable through high-resolution imagery, aiming for low commission error.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count for the primary data table is unknown, which may limit suitability assessment.
• Data is up-to-date through November 7th, 2025; freshness for applications beyond that date should be verified.
