� High System Voltage module can withstand higher system voltage up to

1500V, which is the key differentiator to other products .

• Allow higher system voltage as 1500V

• Lighter weight compared with double glass module

• High static mechanical load 3800Pa / 5400Pa, Dynamic

mechanical load ±±±± 1000 Pa

• Compared to 1000V, 3%~4% Balance of System ( DC side) will be saved by 1500V system voltage (combiner box, cables, string monitor, etc.)

• A faster return on investment
