About Course

IPQC (In-Process Quality Control) involves real-time inspections and checks during the manufacturing process to identify and rectify defects or deviations from quality standards. It helps ensure product consistency and reduces the likelihood of producing faulty items.

OQC (Outgoing Quality Control) takes place at the end of the manufacturing process, just before products are shipped to customers. It involves comprehensive inspections and tests to verify that finished products meet predetermined quality criteria, ensuring that only high-quality items are delivered to customers.

Both IPQC and OQC are essential quality control measures that collectively contribute to the overall quality and reliability of manufactured products.

Course Content

Quality Inspection
Quality inspection in a module line involves systematic checks and assessments to ensure that solar modules meet predetermined standards and specifications. This process includes visual inspections, measurements, and functional tests to identify defects or deviations from quality requirements. Quality inspectors play a crucial role in maintaining product consistency and reliability by detecting and addressing issues early in the manufacturing process. Inspection results inform decisions on product acceptance, rework, or rejection, contributing to overall product quality and customer satisfaction. In a module line, stringent quality inspection practices are essential to deliver reliable and high-performance solar modules to end-users.

Quality System
"Quality system involves cultivating a culture of quality within an organization, encompassing training, communication, recognition, leadership support, and continuous improvement."

PV Module raw materials
PV module raw materials are the essential components used in the production of solar panels. These materials include silicon wafers, which serve as the core of solar cells and absorb sunlight to generate electricity. Encapsulation materials like ethylene-vinyl acetate (EVA) protect the cells, while backsheet materials provide insulation and protection. Electrode materials, typically silver paste, enable the collection of electrical current. Aluminum frames and junction boxes support the module's structure and electrical connections. These materials collectively play a crucial role in harnessing solar energy and converting it into electricity for various applications.

Techniques of QC
The seven significant QC techniques are Statistical Process Control (SPC), Six Sigma, Total Quality Management (TQM), Root Cause Analysis (RCA), Failure Mode and Effects Analysis (FMEA), Poka-Yoke, and Design of Experiments (DOE). These methods employ statistical tools, continuous improvement philosophies, and error-prevention strategies to optimize processes, reduce defects, and enhance overall product and service quality across various industries.

Solar Module classification criteria for Yield
Solar module classification for yield is vital for assessing a panel's performance. Key criteria include efficiency (how effectively it converts sunlight into electricity), temperature coefficient (impact of temperature on performance), tolerance (variation from the rated power output), dust and dirt performance (resistance to dust buildup), and shading tolerance (ability to maintain output in partially shaded conditions). These factors help users choose modules that will deliver optimal energy production and reliability for their specific solar installations.

EL test and inspection standard
Electroluminescence (EL) Test: EL testing is a non-destructive technique for identifying defects in photovoltaic (PV) solar modules. It works by capturing images of modules emitting light under reverse-bias voltage, revealing hidden flaws. EL testing is crucial for quality control, as it detects issues like cracks, delamination, and cell damage. It helps ensure the long-term reliability and performance of PV systems. Inspection Standards: Standards such as IEC 61215, IEC 61730, UL 1703, and ISO 9001 provide guidelines for testing, safety, and quality management in the PV industry. Adherence to these standards ensures that PV modules are safe, reliable, and perform consistently.

Rejects Appearance of solar module
Rejects appearance on a solar module pertains to visible imperfections or defects that can compromise its performance and reliability. These defects may encompass cracks, delamination, discoloration, burn marks, broken cells, or damaged busbars. Such issues can reduce the module's electrical output, efficiency, and lifespan, negatively impacting its overall effectiveness in a photovoltaic system. Effective quality control measures are crucial for identifying and addressing these defects during production to ensure the delivery of high-quality and durable solar panels to customers, minimizing performance issues and long-term maintenance costs.

Final Review
A final review is a comprehensive and thorough examination or assessment conducted at the end of a project, process, or task to ensure that all aspects are in line with the desired goals, objectives, and standards. It involves scrutinizing various elements, checking for errors, discrepancies, or deviations from the original plan, and making any necessary corrections or adjustments. The purpose of a final review is to validate that all requirements have been met, quality is assured, and the project or process is ready for deployment or the next phase. Final reviews are critical for quality assurance and ensuring that the end result aligns with the initial objectives.

6s Occupational Health, Safety, and Environment
6S Occupational Health, Safety, and Environment in a solar module line is a comprehensive approach to ensuring a safe, environmentally responsible, and efficient workplace. It involves six key principles: Sort, Set in order, Shine, Standardize, Sustain, and Safety. This methodology streamlines processes, reduces waste, minimizes environmental impact, and prioritizes the health and safety of employees. By implementing 6S, solar module manufacturing can achieve higher productivity while maintaining a commitment to worker well-being and environmental stewardship.
