Worldwide Patented Reflective Isomeric Ribbon
Based on patented design and dedicated technology, Fundant reflective isomeric welding ribbon provides simple, economical and highly-efficient ultimate solution to the electric confluence ribbon shading problem of PV modules which has troubled the PV industry for many years.
Patented Design + Dedicated Technology
♦ Compatible to the existing PV welding equipment
Simple-and easy-to-use, without the need to change production process
Production efficiency/yield similar to traditional flat ribbon
♦ improving the module's grades distribution
Equivalent to substitute high-grade cells with low-grade ones
Complete specifications, meanwhile provide bulk customization services
♦ Strengthening module weatherability
Superior soldering intensity compared to conventional flat ribbon
Reducing local stress concentration with design of surface grooves

1 The data above is just based on ribbon of 4BB/1.1*0.25mm or 5BB/0.9*0.25mm (total shading area accounts for 2.8% of module
surface area).The competitive power gain is higher of wider ribbon, which secures low - grade batteries to replace high - grade ones.
2 Continue to use the production plan of conventional flat ribbon with two/three lower grade cells substituted.
