The practical question
An ambiguous result can reflect module damage, an unfamiliar module family or an unreliable capture. The next decision is whether to acquire another optional measurement, repeat a capture, stop testing or ask a specialist.
The research approach
The proposed study investigates whether capture conditions and cross-modal physical consistency can improve sequential test selection across unfamiliar retired crystalline-silicon module lots. A PV-specific policy would weigh another optional test or repeat capture against its expected decision benefit and full cost, then stop with an eligible route recommendation or refer the case. PV and ML specialists will define the admissible actions and physical relationships. Required safety and qualification procedures remain outside the policy’s control; independent reference findings establish condition, function and eligibility separately from its recommendations.

Test the decision against independent findings.
The proposed study compares what the candidate policy recommends with qualified reference assessments, then asks what errors, expert work and costs remain.
Representative modules, documented provenance.
Agree the operating context, handling/access protocol, module identity and source-lot records.
Keep related modules and observations together.
Separate development/calibration groups from held-out evaluation groups before preprocessing, fitting and calibration.
Evidence → optional test or stop → update / refer
Record identity, physical observations and capture-quality context. Investigate how measurement reliability and unfamiliar source lots affect the choice to acquire an optional test, repeat a capture, stop or refer. Freeze the policy before held-out evaluation.
Qualified tests → adjudication → findings
Establish condition/function findings and an eligibility rubric. Mask adjudicators to model recommendations where practicable; preserve disputed or unresolved cases.
Operator rules, efficient fixed testing and established adaptive methods.
Give each method the same eligible measurements and information. Compare complete costs at matched routing-error and decision-coverage limits. Keep mandatory safety checks, independent reference findings and downstream eligibility separate from the optional-acquisition policy.
Retain a measurement, revise the policy, stop a pathway or scope the next pilot.
Who would use it
For recyclers, decommissioning firms and repowering operators: evidence about when extra testing earns its cost, when it can stop and when specialist assessment is necessary.
Research to date
Completed Montclair circular-PV feasibility, data exploration and customer discovery established the research foundation. The next physical study is in protocol and access planning. Integrated PV inspection and adaptive feature acquisition already exist; the candidate contribution is a PV-specific method whose advantage under unfamiliar source lots must be tested.
The next validation gate
Agree module access and an independent reference protocol, masking assessors to policy recommendations where practicable. Compare actual operator practice, a cost-tuned fixed workflow, an established adaptive method and the candidate under equivalent measurement access. Keep each module and source lot in one partition; freeze policies, calibration and thresholds before final evaluation. Compare route errors and complete costs at matched decision coverage, with uncertainty intervals. Test capture-quality ablation and prospective workflow timing. Retain simpler methods if they match the candidate or new-lot performance fails.
