PV Quality Control
With quality audits, provided by Solarif Risk Management, the number of problems are reduced to a minimum and are cut from the production process. An intensification of the number of inline audits decreases the potential problems that can arise during operation.
The in-line quality inspection consists of testing and flashing randomly selected PV modules in addition to checks on;
- Raw materials and movement of materials from stock
- Operational excellence of the plant personnel
- Witness testing on site
- Review of the quality systems
- Check if the product requirements are met
Solarif Risk Management performs quality control inspections within the manufacturers factory to coincide with the production run of the client’s goods, covering IQC, IPQC, FQC as well as OQC.
Incoming Quality Control
Incoming Quality Control tool refers to the quality control / sample testing of primary materials. These materials are used during the production of a solar PV module, e.g. cells, interconnectors and junction boxes. This inspection is commonly done on samples. In-Process Quality ControlThis process consists of quality control performed on semi-finished PV modules during the production phase up until curing. Tests typically involved in this process are visual inspection, electroluminescence imaging and primary material inspections and is performed on each piece of the sample.
Final Quality Control
The FQC refers to quality control of finished PV modules after they are cured. It mainly involves visual inspection, electroluminescence imaging, I-V measurement, ground resistance test and insulation test. This step of inspection involves all testing prior to packing and is performed on each piece of the sample.
Outgoing Quality Control
The OQC denotes inspection of final PV modules that are already packed. This test is typically done on the basis of a sampling plan with an acceptable quality limit (AQL). These inspections undertaken on behalf of Solarif Risk Management check the whole process and flow of goods from entry, until they leave the factory.
