GET /api/v1/cities/{slug}/solar

Solar irradiation + PV yield per city (PVGIS, Tier A)

Solar potential per city from the keyless PVGIS computation API (EU JRC, PVcalc). PVGIS computes any EU coordinate, so all cities are covered. A multi-year climatological average at the city centre, normalized to a 1 kWp system at the optimal tilt: annual_yield_kwh_kwp (annual yield kWh/kWp), annual_irradiation_kwh_m2 (global irradiation kWh/m²), optimal_slope_deg/optimal_azimuth_deg and 12 monthly values (monthly). system_loss_pct is the configured (intended) system loss from cabling/inverter/soiling (the loss parameter passed to PVGIS, typically 14 %), NOT the overall performance delta; that is carried separately as total_performance_delta_pct (PVGIS l_total, incl. temperature/irradiance/ angle effects, negative = overall reduction). No observation timestamp, so observed_at=null; the reference period is carried as period_start/period_end. Tier A (EU reuse policy). Toggle off -> 200 source_status="disabled"; dead upstream with no cache -> 503 with a hint.
