Product Overview & System Integration
The 635-665W dual glass solar panel series utilizes high-density 210mm large-format silicon wafers to maximize energy yield per square meter. Engineered strictly for utility-scale grid-tied plants and large commercial EPC projects, this bifacial module captures up to 25% additional rear-side power gain depending on ground albedo. It operates with high stability within 1500V DC system environments, lowering cable and tracker Balance of System (BOS) costs. As a direct China manufacturer, Xiamen Hemao Industry executes precise OEM production orders, offering custom anodized aluminum frame coloring, exact cable length modifications for specific tracking systems, and matched MC4-compatible junction box configurations.

Quality Control & Global Standards
Xiamen Hemao Industry enforces rigorous inline inspection protocols for high-wattage modules. Every 635-665W dual glass solar panel undergoes double 100% EL (Electroluminescence) imaging-once before lamination and once after framing-to eliminate micro-cracks and soldering defects. Modules are subjected to severe salt mist, ammonia, and PID (Potential Induced Degradation) resistance testing. Our manufacturing facility guarantees compliance with IEC 61215, IEC 61730, CE, and TUV international certification standards, ensuring global grid-connection compliance for EPC contractors.

Packaging & Logistics Safety
Heavy-duty packaging is deployed to secure heavy-format 210mm dual glass modules during international ocean freight. We utilize export-grade corrugated cartons reinforced with steel banding on solid wood pallets. Internal corner guards and specialized foam separators isolate glass surfaces to prevent vibration friction. Container loading is optimized for 40HQ vessels, employing vertical portrait stacking and tensioned cargo nets to guarantee zero tilt or mechanical stress during transit.

FAQ
How does the 635-665W dual glass panel perform with 1500V single-axis tracking systems?
This module is explicitly engineered for 1500V DC utility architectures. We provide customized 4.0mm² cable lengths to prevent tension during tracking rotation. The 2.0mm double-glass structure provides extreme rigidity against torsional stress caused by single-axis tracker movements.
What is the exact linear degradation rate for these bifacial solar modules over 30 years?
Our high-efficiency N-type/P-type dual glass modules guarantee less than 2.0% power degradation in the first year. From years 2 to 30, the annual linear power attenuation remains strictly under 0.45%, ensuring at least 84.95% of nominal power output at year 30.
Can we customize the aluminum frame thickness and color for specific high-wind EPC projects?
Yes. As a source factory, we accept wholesale OEM orders. While standard AL6005-T5 frames support 2400Pa wind loads, we can extrude thicker alloy frames or apply black anodization based on your structural engineering data. Minimum Order Quantity (MOQ) applies to custom molds.
