Solar Tabber Stringer
1. Stringer can weld 2 3 4 5 bb cells whose length is 156mm or 125mm. suit for the cutting cells whose length are 32mm 39mm 52mm 78mm.
2. YH3000 stringer machines suit for the width of small cutting cells from 6mm to 52mm
soldering. It means that you can produce 3w to 60w small solar panels automatically by this machine.
3. Real capacity of single busbar could reach 2500pcs/hour.
4. Experienced engineer gives the English operate training and the English aftersales service for free.

 

    Step 1: Solar Cell Efficiency Testing
Ensure all solar cells used in a single panel have consistent power ratings by conducting thorough efficiency tests.

Step 2: Solar Cell Cutting by solar cells fiber laser
Precisely cut complete solar cells into smaller pieces as required.

Step 3: Solar Cells Tabbing & String Welding
Stringe the sliced solar cells into strings through an automated welding process.

Step 4: EVA/TPT Cutting
Cut Solar EVA and TPT Backsheets to the required sizes based on the solar panel glass dimensions.

Step 5: Automated  Solar String Layup
Automatically lay the solar cell strings onto the glass and EVA, then transport the module to the next stage.

Step 6: Visual Inspection
Perform a visual inspection to detect any contaminants or irregularities in the raw materials.

Step 7: Defect Identification
Use an Electroluminescence (EL) tester to identify micro-cracks, broken finger wires, and other hidden defects in the solar modules.

Step 8: Solar panel Lamination (Solar laminator machine)
Laminate the inspected materials into a solid solar panel using specialized lamination equipment.

Step 9: Edge Trimming
Trim the edges of the cooled solar panel after it exits the laminator to ensure a clean finish.

Step 10: Sealant Application
Apply sealant to the edges of the panel for additional protection.

Step 11: Framing By Solar panel framing machine
Install the aluminum frame around the solar panel using a framing machine.

Step 12: Additional Sealant Application
Apply sealant to the aluminum frame joints to ensure a watertight seal.

Step 13: Junction Box Installation
Attach and secure the junction box to the back of the solar panel.

Step 14: Electrical Performance Testing
Use a solar simulator to conduct comprehensive electrical tests, measuring power output, current, and other key performance indicators.

Step 15: Insulation Testing
Test the panel for voltage insulation to ensure safety and reliability.

Step 16: Final Defect Check
Conduct a final EL test to identify any remaining defects in the finished solar modules.

Step 17: Labeling
Label the finished solar panels with all necessary information and certifications.

Step 18: Cleaning and Packaging
Clean the surface of the solar panels and package them securely for shipment.
