PAN File Builder

Beta

Pick a module from the CEC database and we translate its single-diode (De Soto / six-parameter) coefficients into a valid PVsyst .PAN file you can import directly. Every translated parameter is shown with exactly how it was derived and what was assumed — so you can decide whether to trust it.

How faithfully the stored CEC coefficients reproduce the module's nameplate keypoints. Large gaps here mean the underlying CEC fit is imperfect — the PAN will inherit that error.

Methodology & Assumptions

Same circuit, different bookkeeping

The CEC (De Soto six-parameter) model and PVsyst both solve the single-diode equation. The translation re-expresses CEC's coefficients in PVsyst's terms rather than re-fitting anything:

Gamma = a_ref / (Ns · k·Tref/q) — CEC stores the ideality factor as a voltage (a_ref); PVsyst wants it dimensionless.
RSerie = R_s — series resistance is one constant in both models, copied directly.
RShunt = R_sh_ref — CEC's reference shunt resistance is PVsyst's shunt at STC.
Temperature coefficients (muISC, muVocSpec, muPmpReq) are unit-converted from CEC's alpha_sc / beta_oc / gamma_r.

Where the two models diverge

The honest gaps — these are PVsyst defaults, not CEC-derived:

Where output may differ from an OEM PAN

A manufacturer's official PAN is fit to measured flash-test data across irradiance and temperature. This file is reconstructed from CEC's STC-anchored coefficients, so the closest agreement is at STC. Expect small differences in low-light efficiency (driven by the Rp_0 / Rp_Exp shunt model) and in the Isc temperature response (CEC's Adjust factor is not transferable). Bypass-diode reverse characteristics and the IAM profile use PVsyst defaults.
