Packaging & Logistics Safety
Bulk export shipments utilize heavy-duty, moisture-resistant wooden pallets engineered for long-distance marine transport. Each pallet incorporates anti-collision corner guards, internal reinforced strapping, and rigid carton enclosures to prevent transit stress. Optimized container loading metrics (e.g., 36 pcs/pallet, 864 pcs/40HQ) maximize freight efficiency for B2B wholesale buyers.

FAQ
Q: How does this 450W mono TOPCon panel integrate with existing 1500V string inverters?
A: The panel supports 1500V DC maximum system voltage, reducing total string quantity and BOS costs. Standard MC4-compatible connectors and optimized short-circuit current strictly match leading hybrid and string inverter MPPT parameters without clipping.
Q: What is the exact linear power degradation curve over the 30-year warranty?
A: N-type TOPCon technology limits first-year degradation to <1.0%. From year 2 to 30, annual power attenuation remains strictly under 0.40%, guaranteeing an 87.4% nominal power output retention at the end of the 30-year lifecycle.
Q: Can regional distributors request custom frame colors and private OEM labeling?
A: Yes. We execute batch OEM services for wholesale orders. Hardware customization includes black or silver anodized aluminum alloy frames, custom backsheet options, specific cable lengths, and laser-printed corporate logos directly on the module rating labels.
