Product Overview & System Integration
This series of 430W to 455W monocrystalline modules leverages N-Type TOPCon technology to eliminate Light Induced Degradation (LID) and LeTID. Engineered for global EPC requirements, these panels are compatible with mainstream string inverters and micro-inverters. As a source manufacturer, Hemao provides deep customization, including specific cable lengths (MC4/MC4-EVO2), frame thickness (30mm/35mm), and private labeling for regional wholesalers. Each module is optimized for high-density container loading to reduce per-watt logistics costs in large-scale utility and commercial deployments.

Quality Control & Global Standards
Our Xiamen facility implements a 100% triple EL (Electroluminescence) testing protocol-before lamination, after lamination, and before final packaging-to eliminate micro-cracks and hotspots. All 430W-455W modules are certified under TUV Rheinland, CE, RoHS, and ISO9001. Our N-Type cells undergo rigorous salt mist (IEC 61701) and ammonia corrosion (IEC 62716) testing, ensuring long-term reliability in coastal and agricultural environments.
Packaging & Logistics Safety
To prevent cell micro-fractures during maritime transit, modules are packed in reinforced vertical crates with protective corner spacers. We utilize 40' HQ containers with specialized anti-vibration dunnage bags and steel-strapped wooden pallets. For LCL shipments, additional plywood casing is available to meet 9-layer stacking safety requirements.

FAQ
How does the N-Type TOPCon technology in your 455W panels benefit high-temperature regions?
N-Type cells have a significantly lower temperature coefficient compared to traditional P-type PERC modules. In environments exceeding 40°C, our 455W panels maintain higher voltage stability, resulting in approximately 3-5% more energy yield over the system lifetime, directly improving the project's Levelized Cost of Energy (LCOE).
Can the frame and backsheet be customized for specific aesthetic or environmental needs?
Yes. For residential wholesalers, we offer Full Black (black cell, black backsheet, black frame) options. For utility-scale projects in harsh environments, we provide 35mm reinforced frames and specialized backsheets with enhanced UV resistance and anti-corrosion properties to meet specific EPC tender specifications.
What is the standard lead time and OEM capability for 1MW+ container orders?
Our factory maintains a monthly capacity of 500MW. For standard 430W-455W mono modules, the typical lead time is 15-21 days. We offer full OEM support, including custom cable lengths, logo laser printing on the frame, and customized pallet dimensions to fit specific local warehouse racking.
