Product Overview
This 400-watt solar module represents the forefront of monocrystalline PERC (Passivated Emitter and Rear Cell) technology. Designed with 144 high-efficiency half-cut cells, it maximizes power output while minimizing performance loss from shading and high temperatures. The panel features a durable anodized aluminum frame, tempered glass with high light transmittance, and robust junction box with bypass diodes. It is certified to international standards (IEC, UL) and comes with industry-leading performance and product warranties, offering peace of mind for your critical energy projects.
Key Features
- High-Efficiency Monocrystalline PERC Cells: Achieves module efficiencies exceeding 20.5%, generating more power per square meter and optimizing land/roof space utilization.
- Half-Cell Technology: Reduces internal current and resistive losses, lowers operating temperature, and improves performance in partial shading conditions.
- Enhanced Durability: Constructed with anti-PID (Potential Induced Degradation) cells, salt mist, and ammonia corrosion resistance, suitable for harsh environments.
- Advanced Weather Resilience: Withstands high wind loads (2400Pa) and snow loads (5400Pa), ensuring structural integrity in diverse climates.
- Smart Bypass Diodes: Integrated diodes minimize power drop caused by shading, soiling, or cell mismatch, maintaining higher system output.
- Lower LCOE (Levelized Cost of Energy): The competitive 400 watt solar panel price, combined with high energy yield, results in a lower lifetime cost of electricity generation.

FAQ
What factors influence the final 400 watt solar panel price for a large order?
The final price is determined by order volume (container loads), Incoterms (FOB, CIF, etc.), current market pricing for raw materials like polysilicon, and specific certification requirements. We provide transparent, volume-based quotations.
Do you offer OEM services or custom branding?
Yes, for bulk orders, we can provide OEM services, including custom packaging, logos on the panels and junction boxes, and tailored documentation to meet your brand specifications.
What is the typical lead time for a 1MW order?
For standard products, lead time is typically 2-4 weeks after deposit confirmation, depending on factory schedule. We provide clear production and shipping schedules upon order confirmation.
How does the 25-year linear power warranty work?
We guarantee that the panel will deliver at least 97% of its rated power in the first year, with a gradual decline not exceeding 0.55% annually, ensuring a minimum of 85% of original power output at the end of year 25.
Can you provide test reports and certification documents?
Absolutely. We provide full certification documents (IEC, UL, etc.), recent third-party lab test reports (e.g., from TÜV, CSA), and factory audit reports upon request to facilitate your project due diligence and financing.
