Situation
Solar cells are subject to various loads. Thermal expansion places loads on the soldered contacts between tabbing and printed busbars both during production and during solar module use. However, these contacts still have to provide loss-free conductivity over the entire life of the module. The GP PULL-TEST .Advanced combined with the GP STAB-TEST .Pro evaluates the quality of these contacts through reliable measurement of adhesion force of the tabbing on the cell.
Principle
- Adhesion force measurement of the tabbing on the cell
Advantages
- Numerous different measurements can be performed
