Technical Specifications & Buying Guide
Selecting the right solar modules depends largely on project size, climatic conditions, and budget constraints. As a supplier specializing in tiered distribution, we categorize our wholesale inventory by technology to meet a variety of grid requirements.

Products Description
The durability of a solar module is dictated by its BOM (Bill of Materials) and assembly precision. Our manufacturing process integrates multi-busbar (MBB) and half-cut cell technologies to reduce internal resistance and mitigate shading losses.
We utilize high-transmittance, low-iron tempered glass (3.2mm for standard, 2.0mm+2.0mm for dual-glass) combined with anti-PID (Potential Induced Degradation) EVA encapsulation. The frames are constructed from anodized aluminum alloy, engineered to withstand wind loads up to 2400 Pa, and snow loads up to 5400 Pa. This industrial-grade mechanical stability ensures minimal micro-cracking during transit and installation.

Why Choose Hemao Industry
As a direct manufacturer, we ensure supply chain transparency and technical accountability, while strictly controlling quality at every stage.
High Annual Production Capacity: Our highly automated production facilities can handle large-scale orders and strictly adhere to delivery schedules.
Dual EL Inspection Process: Every module undergoes two electroluminescence (EL) imaging inspections—one before lamination and one after—to ensure zero hidden microcracks.
Global Certifications: All production lines comply with ISO 9001/14001 standards. Our modules hold TÜV, CE, and INMETRO certifications, ensuring compliance with grid connection requirements in international markets.
OEM/ODM Flexibility: For bulk purchase customers, we offer custom label printing, specific anodized frame colors (silver/black), and variable cable lengths (300 mm to 1,200 mm).

Frequently Asked Questions
Q: How do you handle warranty claims for bulk shipments?
A: We provide a 12-year product material warranty and a 25-year (30-year for dual-glass) linear power output warranty. Claims are processed directly through our engineering department based on flash test data and serial number tracking.
Q: Are your N-Type TOPCon panels compatible with standard micro-inverters?
A: Yes. Our N-Type modules are engineered with standardized electrical parameters (Voc and Isc) to ensure full compatibility with major string inverters and micro-inverters used in commercial and residential arrays.
Q: Do you offer third-party inspection prior to factory dispatch?
A: Absolutely. We welcome third-party quality control agencies (such as SGS or Intertek) to conduct pre-shipment inspections (PSI), flash test verifications, and visual checks at our facility.
