Production Oversight

This service includes experienced SolarBuyer Quality Engineers deployed in the factory during manufacturing of product for your project(s). Our Engineers monitor production to ensure that all critical material, process and production controls are applied – and applied correctly.

We ensure that only certified, qualified materials and components are used. We also verify that only qualified factories and workshops are used to manufacture the product and track product by serial number. Our Engineers don’t just check that the manufacturer is following their own standards and procedures; we also check the standards and procedures themselves for any gaps or weaknesses.

The Engineers can have the authority to stop production or reject product if controls do not meet pre-defined standards and criteria. Batch-based management reports are provided with details of all findings and actions taken to protect quality.

Overseeing production is the only way to ensure certain critical defects caused by poor controls are identified and removed. These types of defects CANNOT be identified and screened in the final product. Examples include poor soldering or lamination – serious defects that can impact the safety, reliability and performance.

SolarBuyer provides criteria against which manufacturing performance during production oversight can be measured, assessed and utilized to accept / reject product. This service typically includes oversight of the following areas within production – any of which may be tailored dependent on the risk profile of the particular manufacturer:
