Efcient – high-perormance – reliable. 

Solar cells rom Bosch Solar Energy.

High perormance – Stable yields.Bosch Solar Cell M 3BBC3 1200

Our monochrystalline solar cells oer impressive eatures including:

High annual yields, even with sub-optimal levels o sunlight,

thanks to excellent perormance in weak light conditions

Exceptionally stable perormance thanks to using purest silicon and to

high-resistance waers, produced in-house

Improved cell processing as a result o narrow perormance tolerances

Reliability o short and long term supply, due to high production capacity

Pioneering 3-busbar technology reduces the series resistance and helps

to boost the power output in the module

Packaging:

150 pack as smallest packaging unit

Suitable or controlling/checking incoming goods digitally using a barcode system

Production & quality control:

100 % classifcation under IEC 60904 and IEC 60891

100 % testing o reverse-current

Regular calibration at Fraunhoer ISE
