Product Features

1. Multi-grid line battery: strong current collecting ability, special circuit design brings lower heat spot humidity;
2. Anti-PID: Excellent PID resistance in 96 hours (85 ° C /85%) testing, and can also be improved to meet higher standards, suitable for particularly harsh environments;
3. Bursting crack: excellent resistance to cracking, more balanced internal stress;
4. Module efficiency up to 21.16% : The half-cell structure process results in low resistance characteristics, higher generation and lower power attenuation;
5. Low light performance: Excellent power generation performance under low light conditions due to multiple grid lines;
6. Strong mechanical load capacity: tested at 2400Pa wind pressure and 5400Pa snow pressure, ensuring a stable mechanical life of the components.
