Shipping Notice for 600W+ Solar Panels
All solar panels rated 600W and above exceed liftgate size restrictions and cannot be unloaded via liftgate. Residential deliveries require the customer to provide appropriate unloading equipment (forklift, skid steer, or equivalent) at the delivery location. Failure to provide equipment may result in re-delivery fees assessed by the carrier.
Key Technology
-
N-Type TOPCon 16BB Half-Cut Cells
Lower LID/LeTID degradation and superior low-light performance for improved lifetime energy production. -
Bifacial Dual-Glass Construction
Rear-side gain, depending on albedo, significantly reduces LCOE and increases total system yield. -
Excellent Anti-PID Performance
Passed 192-hour Anti-PID testing for enhanced durability in harsh environments. -
Robust Environmental Resistance
Designed for high-humidity, dusty, and windy regions with IP68-rated junction box. -
Industry-Leading Degradation Rate
≤1% first-year degradation and ≤0.4% annual linear degradation over 30 years.
Best Uses
-
Utility-Scale Solar Farms
High 620W power output reduces BOS costs and improves installation efficiency. -
Commercial & Industrial Ground-Mount Systems
Optimized for tracker systems and high-density arrays. -
Bifacial Installations
Maximizes yield over reflective surfaces such as white membrane roofs or light-colored ground.
Warranty
- Product Warranty: 12 Years
- Performance Warranty: 30-Year Linear Power Output Guarantee
- First-Year Degradation: ≤1%
- Annual Degradation: ≤0.4%
- Guaranteed Output at Year 30: 87.4%
