MCP server for US solar market data: permitting timelines (SolarTRACE), installed systems (Tracking the Sun), utility-scale plants (USPVDB), AHJ lookup
Listed on its own since 2026-09-27. Until then it was part of solar-data, where its earlier checks remain.
Wellknown found it in public sources; nobody has proven control of it yet. Claiming takes one click if the repository is under your GitHub account, or a small file on your domain otherwise. Verified owners get the badge, 15-minute checks, status alerts, edits that outrank crawled data, and a ranking boost.
Agents can do it too: POST https://wellknown.network/api/v1/claims with {"agent":"solar-data-mcp-market","method":"well_known_file"} — machine-readable steps at claim.json, guide at /docs/claim.
Everything here was measured by our prober or read from a registry. Nothing is self-reported.

# solar-data-mcp-market MCP server for US solar market intelligence — the market domain of [solar-data-mcp](https://github.com/hoodsy/solar-data-mcp). | Tool | Answers | |---|---| | `query_installed_systems` | "Median $/W in CO since 2022?" (LBNL Tracking the Sun) | | `get_permitting_timelines` | "How long does permitting take in Denver?" (SolarTRACE) | | `find_utility_scale_projects` | "Biggest solar farms in Texas — batteries?" (USPVDB, live) | | `identify_ahj` | "Who issues the permit here?" (SunSpec registry; token by email) | | `market_snapshot` | One-call state overview: installs, $/W, permitting, big projects | | `sync_tracking_the_sun` / `sync_solartrace` | Load the bulk datasets into the local store | The bulk datasets sync into a local DuckDB store with explicit `sync_*` tools and cited vintages — query tools tell you which sync they need. No API keys required. Run standalone: `uvx --from solar-data-mcp-market solar-market-mcp` — but not alongside `solar-economics-mcp` (both open the same single-process DuckDB store). Most users want the combined [`solar-data-mcp`](https://github.com/hoodsy/solar-data-mcp/blob/main/packages/solar-data-mcp/README.md) server instead — all four domains plus the skill and report layer on one install. Quickstart: [repo README](https://github.com/hoodsy/solar-data-mcp#quickstart).
