In addition to the photovoltaic cells, a solar panel is made up of a number of other photovoltaic cells, each of which is different in size (depending on the number of cells required to convert sunlight into electrical energy), and is made up of several photovoltaic cells. The requirement for precise power conversion necessitates the maintenance of control throughout the manufacturing process, both before and during the manufacturing process itself.

Pre-production is the stage that occurs prior to the start of production.

  • Several steps must be completed before the actual manufacturing process can begin, including pre-selection of the cells that will be integrated into the final solar panel, verification of the glass control process for mechanical resistance and transparency control, verification of the lamination time, and confirmation of the various stages of control that will be implemented during the manufacturing process


Following the completion of a production, it is customary to

According to ProQC, manufacturers should conduct Pre-Shipment Inspections (PSI) after the solar panel has been fully assembled in order to ensure that the final product is of high quality and meets customer specifications.

An extensive number of different components of the complete solar panel are examined during the final quality control inspection process. Following is a checklist that should be used as a guideline for the end-to-end verification process:

The first step is to conduct a visual examination.

Cosmetic and sanitary condition of the product – the product's overall appearance and cleanliness


Each system is subjected to a visual inspection to ensure that the solar panels, batteries, inverters, solar chargers, cables, and other accessories all have an appealing overall appearance. Damage or deformation of any kind (including scratches, dents, and dirt) must be avoided at all costs on each of these.

Check to see that the sealant around the edges of the solar panels is tight and properly adhered to the panels.

Examine the product to make sure that nothing is broken, that there are no cracks in the solar panel laminate, that the frame is not damaged, that all of the fixing/installation/drain/grounding holes, junction box, and anything else specified in the product specifications are present, and that the product meets all of the requirements.

Make sure the correct branding and origin of the various components are present, including the following: glass, tedlar, aluminum frame, cells, junction box, cables, MC4 connector, inverters, solar chargers, and batteries, among others;

2. Dimensions are checked for accuracy:

Dimensions are measured in length, width, and thickness.

A comparison of the diametrical differences Labels are a way of categorizing something.

3. Examination of the Product's Function and Special Features: Because the product must conform to all of the information provided, the solar panel quality inspection services inspection must include examinations of the product's operation and special features.

Measurements of power, voltage, and current are made. Charge and discharge tests should be performed.

Use a high-potency liquid to conduct the test.

Taking the temperature is a must.

Make sure there is no polarity.

Make sure everything works properly by testing a solar-panel setup by connecting the inverter, solar charger, and batteries in the most complete manner possible to ensure that everything works properly.

4. Inspect the logo, labeling, and markings to ensure they are correct:

All barcodes must be free of debris and properly positioned in accordance with the manufacturer's instructions.

The logo's quality, colors, size, positioning, and alignment are all important considerations to take into account.

Labeling and marking: Make certain that the label contains accurate information and that it is properly marked. Labeling and marking:

Product rating labels are checked and examined to ensure that they are accurate and that they meet all applicable standards.

5. Inspect the packaging for any damage:

It is necessary to inspect the contents of the package as well as the quantity of items and accessories contained within ISO9000 Quality System Audit.

There has been adequate protection provided for the contents of the box in order to prevent any damage during transit. The shipping marks and labels have been placed in the proper locations.

The artwork on the retail packaging is correct in all respects.

Within the package, it is critical to have the appropriate printed literature available for use.

Inspectors from outside the solar panel manufacturing industry can provide valuable insight into the process of quality audit control in the industry.
