- Three advanced core technologies:
- Ultimate crystalline silicon solar cell technology HPBC 2.0
- Innovative TaiRay wafer
- Cutting-edge Industry Technology 0BB
Economical and Value-added
- Added installed capacity in same area
- Additional power generation in same area
- Additional generation income
- Anti-shading function recovering power loss
Safe and High Reliability
- Preventing localized overheating to eliminate hazards
- High-strength/thicker TaiRay wafers reduce hidden cracks
- Unique cell welding structure, excelsior qualified BOM & process
- Heightened full-scene test ensures 30-year power warranty
Aesthetic
