More solar data near Sagadahoc County

County assignment is derived from installation ZIP codes via the Census 2020 ZCTA↔county crosswalk (primary county by land-area overlap) — approximate at county boundaries. Market penetration = recorded installations ÷ housing units (U.S. Census Bureau ACS 5-Year, Table B25001); it undercounts where dataset coverage is partial. See methodology.
