Each service can be commissioned on its own or combined into a project-specific quality surveillance plan, from supplier qualification, through active production and shipment release, to receiving and corrective action.
Independent assessment of quality-management-system maturity, process controls, personnel competency, equipment and calibration, material management, in-line and final testing, document control, and finished-product handling. Ideal before you approve a new supplier or place high-volume orders.
On-site oversight during active production to verify the approved bill of materials, work instructions, control plans, process parameters, in-line inspections, testing, and the disposition of nonconforming product. Catches material substitutions and process drift while they are still correctable.
Lot-based release inspection using agreed acceptance criteria and AQL sampling: visual review, EL image assessment, flash/IV verification, hipot and ground-continuity checks, labeling, packaging, and sample traceability, with a clear pass, hold, or reject disposition supported by evidence.
Verification after transport to identify handling damage, hidden cell cracking, packaging issues, and shipment condition before modules are released to installation, so transport-induced defects are caught at the warehouse, not on the racking.
Finding classification, containment review, root-cause challenge, 5D/8D evaluation, objective-evidence verification, and closure support for recurring or high-risk quality issues, pushing corrective action to close the cause, not just the symptom.
Review or development of inspection plans, sampling logic, quality gates, SOP expectations, defect criteria, traceability requirements, records, and escalation workflows, giving your team a repeatable, defensible framework for every future order.
Reports are only as good as the observation behind them. That is why the work happens on the floor, at incoming inspection, on the line during production, and at the loading dock before release, verifying that what was approved is what is actually being built and shipped.
Scope is tailored to the contract, module technology, factory risk, and project phase. Reviews can reference client specifications, approved quality plans, AQL criteria, manufacturer procedures, and applicable IEC or ISO requirements where relevant.
Inspected to recognized methods: IEC 61215 & IEC 61730 (module design & safety), IEC 60904 (PV measurement), ISO 2859-1 (AQL sampling), and ISO 17020 inspection practice.
The deliverable should make the next decision easier. Reports are designed to separate high-risk issues from noise and make closure requirements explicit.
Findings are prioritized by potential impact to safety, reliability, conformity, traceability, and project acceptance.
Photos, records, serials, process data, procedures, interviews, and observations support the conclusion.
Recommendations focus on containment, root cause, systemic prevention, and verifiable closure.
Executive summaries and detailed technical findings serve procurement, engineering, quality, and management.
Tell us the project phase, supplier, location, volume, and timing. We will recommend the right combination of services and sampling intensity.
No manufacturer ties. No conflicts of interest. Just the evidence.
Sisoko works only for the party commissioning the inspection, your interests, documented objectively.
