Trina Solar secures first commercial order for perovskite-silicon tandem solar modules in New Zealand

This development reflects the completion of Trina Solar's full innovation cycle - from laboratory research and standardized product development to large-scale global commercialization.

Compared to conventional crystalline silicon modules, the tandem panels offer clear advantages. Their high conversion efficiency can reduce balance-of-system (BOS) costs by approximately 15%-20%, lowering overall system costs.

In addition, improved temperature coefficients and low-light performance can increase energy yield by 20%–30% per installation area, maximizing rooftop utilization and economic returns.

The New Zealand project validates the global applicability and competitiveness of the company's tandem technology while establishing a scalable model for expansion into other high-end distributed markets.

This achievement set a new world record for tandem module performance and marked the 41st record set by the company in the PV sector.
