Performance Advantages

Premier TOPCon Solar Panels are designed to deliver outstanding performance, efficiency, and long-term reliability. Utilizing advanced N-Type TOPCon cell technology, these modules achieve higher energy conversion efficiency, allowing more power generation from the same installation area. Their low temperature coefficient helps maintain stable performance even in hot weather conditions, while the bifacial design captures sunlight from both the front and rear sides to increase overall energy yield.

Higher Efficiency

Achieves module efficiencies ranging from 22.0% to 23.3%, enabling greater energy production from the same installation area.

Lower Temperature Coefficient

Maintains stronger performance under high-temperature conditions with a temperature coefficient of approximately -0.30%/°C.

Superior Bifacial Gain

The bifacial design captures reflected sunlight from both sides of the module, increasing total energy yield by up to 85% under optimal conditions.

Reduced Degradation

Advanced N-Type technology minimizes LID and LeTID effects, ensuring consistent power output throughout the panel's lifespan.

Electrical Specifications (STC)

The Electrical Specifications (STC) represent the solar panel’s performance under Standard Test Conditions, providing a reliable benchmark for evaluating power output and efficiency. Premier TOPCon Solar Panels deliver a power range of 430W to 455W with module efficiencies reaching up to 23.3%, ensuring excellent energy generation from available sunlight.
