Cold string voltage (V)
Linear temperature-corrected open-circuit module voltage × series count; verify device voltage limits separately.
Hot string voltage (V)
Linear temperature-corrected open-circuit module voltage × series count; verify device voltage limits separately.

Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; Linear temperature-corrected open-circuit module voltage × series count; verify device voltage limits separately. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
