5 Limitations Of Current Crystalline PV Modules Aluminium frames required for strength and protection Metal frames needs to be earthed Heavy & Rigid construction Extremely susceptible to micro cracks and power loss Cell interconnections can be damages due to fatigue and residual stress Comparatively inefficient current collection design

6 Key Considerations for Innovation Improve performance by reducing losses Eliminate tradeoff between form factor and efficiency Increase Cell & Module reliability, reduce micro crack impact Avoid new materials, radically different manufacturing processes Reduce installation costs and time

7 Merlin PV Modules By Waaree Energies Technology Partner: Merlin Solar, USA

8 Merlin Module Types High Efficiency Crystalline Cells with Multiple Form Factors Fold Up Modules Flexible/Frameless Modules Roll Capable Modules

9 Merlin Module Features Merlin technology is designed to protect against vibration induced damage to solar panels: Strengthens solar cell by sandwiching the fragile silicon wafer between two copper grids and reduces extent of cracking. By collecting current in a distributed fashion, Merlin eliminates the electrical impact of cell cracks Demonstrated resistance to fatigue related interconnect failure, a big performance & reliability issue

10 Merlin Module Features Merlin Module Characteristics: Cell technology agnostic Can be integrated into existing production lines Upto 3.5% more power compared to std. modules 50% reduction in silver usage 180+ Cell interconnects for redundancy Frameless Light Weight - 9Kgs weight (60 cell module) Can be glued to the roof of vehicle/building

11 Rugged Field Performance Merlin As Manufactured 3BB As Manufactured Merlin Post Field Deployment 3BB Post Field Deployment

12 Tested and Proven Technology 30 µm finger width improves efficiency Extreme Crack & bend Tolerance Minimal Power Loss due to cell damage In High Vibration Test

13 Higher Normalized Energy Yield 0.9 Watt Hour (Generated) / Watt Peak (Rating) of Merlin Vs 3BB Module Wh/Wp Merlin 3BB Time of The Day Intermittently Cloudy, 37 Day Cumulative Data, Roof Mount, California. Certification Lab Data

14 Merlin Advantages Frameless modules can be racked/mounted faster Lower BoS/MMS cost Peal & Stick/Back rail mounting options Flexible modules for curves surfaces or Vehicles Better efficiency and power output Minimal power loss due to cracks and physical damage Improved module reliability and life Better aesthetics

15 Merlin Peal and Stick Application

16 Merlin Transportation Applications High efficiency modules suitable for roof mounting on railway coaches Flexible modules permit better integration to curved rood space Extreme vibration tolerance minimizes damage during high speed movement No compromise of performance for better form factor Ideal for electric buses, trucks, e-rickshaws Electric car charging stations can employ Merlin Modules Traditional Modules Are not well suited for Mobile applications due to large footprint
