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 Busbarlayout.
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 Shadingon 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 GautamSolar’sRound Ribbon Technology boosts Panel Performance
GautamSolar’ssuperior technology
GautamSolar 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
GautamSolar uses NDCover 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
GautamSolar 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
I
mpBinning reduces String mismatch losses
