  "notes": "CEC certified PV module database, 21 535 modules snapshotted from NREL SAM's bundled copy of the California Energy Commission Solar Equipment List (accessed via pvlib.pvsystem.retrieve_sam('CECMod')). Column 0 = P_mp_stc (module max-power at STC, W); columns 1..25 keep ALL upstream per-module parameters verbatim (5 datasheet I-V key points, 3 temperature coefficients, T_NOCT, 5 De Soto single-diode parameters, SAM Adjust factor, N_s cell count, A_c / Length / Width geometry, PTC power, Technology / Bifacial / BIPV categorical flags, manufacturer module_id, SAM DB version and date). Three ground-truth formulas: (1) single_diode_pmp solves the full De Soto 5-parameter I-V equation via pvlib.pvsystem.singlediode (Lambert-W closed form) and recovers P_mp_stc to numerical precision by construction -- R^2 ~ 1 by tautology; (2) power_from_imp_vmp is the trivial P = I V identity, exact modulo floating-point round-off; (3) efficiency_area_scaling uses a single global mean efficiency eta_bar = 0.1539 and reaches R^2 ~ 0.67, serving as the low-information aggregate baseline. Additional scalings retained via kept columns (V_oc from a*ln(I_L/I_o) R^2 ~ 0.9999, PTC from SAPM temperature model R^2 ~ 0.98) are documented in description.md but not shipped as separate formulas."
