Passports Array Builder Impact Second Use

Grades used solar panels against each other, then wires them for the most power.

Measurements come from the Afterglow bench: every panel's short-circuit current at the same instant, its open-circuit voltage, then a sweep of each wiring. Grades compare panels measured together under the same light. Demo panels are simulated and always labelled as such.
