3. TECHNICALLY ADVANCED SOLAR PANELS
4. Fully Automated Manufacturing Setup ADVANTAGES of using Top-Notch Machines:  Precision and Accuracy in Engineering  Minimized Errors and Defects  Increased Production Yield
5. Robotic Layup vs. Gantry Layup DISADVANTAGES of the conventionally used Gantry Layup:  Lower Production Yield  Low Precision in String Positioning on EVA Sheet  Limited Flexibility  Depends on operator skills • Comparatively low investment costs • Established technology and operator familiarity also deters shift to robotic layup.
6. Robotic Layup vs. Gantry Layup Using ROBOTIC LAYUP instead of Gantry Layup in production:  Enhances Production Yield  Ensures Precise String Positioning on EVA Sheet  Solves String Misalignment  Boosts overall panel performance and durability •Robotic Layup requires higher investment •Adoption of latest technology provides a competitive edge and positions Gautam Solar as an industry leader
7. Fully Automatic High-Speed MBB Stringer Using “MERCEDES OF SOLAR STRINGERS” to ensure:  Lower Electrical Losses due to MBB Design  Higher Accuracy with CCD Positioning  Reduced Errors due to Non-contact Infrared Soldering •Require more investment than conventional stringers •Provides long term benefits like enhanced durability •Ensures customer satisfaction
8. Going from Flat to Round Ribbon Flat Ribbon: Drawbacks and Why they still persist What are they? Metal connectors used for connecting various cells in a solar panel. Traditionally used with 5 Busbar layout. Provide Lower Light Utilization. Majority of light falling on ribbon is reflected outside. Only 5-10% is reflected inside and converted to electricity. What are their drawbacks? Flat Ribbon (0.9 mm width) cover significant amount of cell area. Increased Shading on the photosensitive silicon base limits the power generation. Flat Ribbons still persist due to their compatibility with conventional stringers, which require low investment.
9. Going from Flat to Round Ribbon How Gautam Solar’s Round Ribbon Technology boosts Panel Performance Gautam Solar’s superior technology Gautam Solar incorporates Round Ribbon Technology in Multi-Busbar (MBB) Layout. Innovative technology helps ensure superior panel performance. Provide Higher Light Utilization Multiple reflections inside the module ensures that 70% of the light striking ribbon surface is converted into electricity. Benefits of Round Ribbon Technology Round Ribbon (0.35 mm dia) cover much less cell area. Provide 75% Lower Shading Losses. Leads to 2.5% Higher Module Power. Round Ribbons only work on MBB Cell Soldering Stringers, which require much higher investment.
10. Non-Destructive Cutting (NDC) Machine Gautam Solar uses NDC over conventional cutting:  Low Temperature Laser cutting (<130°C)  Lower Chances of micro-cracks  High mechanical strength of solar cells  No Heat-affected Zone More expensive than conventional cutting machine
11. Non-Destructive Cutting (NDC) vs. Conventional Cutting Half-cut cell technology boosts solar panel energy generation by fitting more cells per panel. Enables independent operation of top and bottom halves and ensures continuous power output even when shaded. Cells scribed by high-temperature laser (>1500°C) and split using mechanical separation High chances of micro-cracks Low mechanical strength (almost half of full cell) Formation of heat affected zone (80-150 µm) Disadvantages of conventional cutting method: Conventional cutting process requires low investment.
12. Non-Destructive Cutting (NDC) vs. Conventional Cutting Gautam Solar uses Non-Destructive Cutting (NDC) Process for producing half-cut cells. Advanced cutting process based on the principle of thermal expansion and contraction. Enhances the reliability and module efficiency. Cells scribed by low-temperature laser (<130°C) and separated using controlled thermal stress Negligible chances of micro-cracks High mechanical strength (similar to full cell) No heat affected zone formation Benefits of Non-Destructive Cutting method: NDC process requires specialized machines and represent huge investments.
13. Solar Panel Curing Line/Room Gautam Solar utilizes an Advanced, Fast Curing Technique with benefits:  Enhanced Longevity and Performance of Panels  Automatic Loading and Unloading  Energy Efficient and Eco-friendly • Some manufacturers don’t employ dedicated curing room • Caused by capital/space constraints • Detrimental to quality of panels
14. Automatic Sorting for Module (Imp ) Binning  Sort modules according to test results  Easy Handling of modules  Automatic and Precise arrangement of modules  Imp Binning reduces String mismatch losses
