Meyer Burger Investor Presentation

4 KEY BENEFITS SMARTWIRE CONNECTION TECHNOLOGY (SWCT®) 3 2 1 MEYER BURGER Busbar SmartWire MAXIMAL ABSORPTION > The geometrical shape of the thin round wire reduces the effective shading on the active surface of the solar cell by up to 20% due to their significantly smaller contact surface Glass OF SUNLIGHT > Sunlight is reflected on the round wire surface and trapped in the module MINIMAL ELECTRICAL > SWCTⓇ reduces the electrical loss by spreading the current with up to 38 wires LOSS > 2% increase in module output is thus possible HIGH DURABILITY AND RESILIENCE > Modules with SWCTⓇ meet IEC criteria in triplicate, which is far beyond the industry standard > In addition, the modules are highly resistant to mechanical stress and tolerate a wide range of climatic conditions RESOURCE SAVER > SWCTⓇ with significant reduction in silver consumption › Copper electrodes are encased using an exclusive alloy and are mounted directly on the thin contact fingers without a silver busbar print > SWCTⓇ it is a resource-saver and futureproof¹ as it does not use any indium or lead and already fulfills the RoHS Directives for hazardous substances Notes: 1) Fraunhofer Gutachten 05/2020 Source: MBT SWCT Factsheet 05/2019 Power performance Glass Busbar Active surface SWCT Active surface Solar cell Solar cell 5BB 98% SWCT ■IEC 95% 98% 98% 61215M Standard 1x 2x 3x Lifetime simulation.
