High-Efficiency Bifacial Double-Glass Solution

 

Maximize your utility-scale energy yield with the next generation of photovoltaic technology. The TWMNF-66HD series represents a breakthrough in N-type TOPCon cell architecture, delivering a massive 735W nominal power output specifically engineered for large-scale solar projects and demanding industrial environments.

 

By integrating 132-cell half-cut technology with a robust bifacial double-glass structure, this module sets a new benchmark for LCOE (Levelized Cost of Energy) reduction and long-term asset reliability.

735W N-type

Why Professional EPCs Choose 735W N-Type Series

 

1. Superior Bifacial Energy Yield (BNPI)

Unlike mono-facial panels, our bifacial double-glass design captures reflected light from the rear side. Under Bifacial Nameplate Irradiance (BNPI) conditions, the TWMNF-66HD735 reaches an impressive 811.5W. Depending on the albedo of the ground surface (sand, concrete, or snow), you can expect a bifacial gain of up to 25%, pushing the effective power output toward 918W.

 

2. Industry-Leading Temperature Coefficient

Heat is the enemy of efficiency. This module features a low temperature coefficient (Pmax) of -0.28%/°C. In hot climates like the Middle East or Southeast Asia, this ensures your system maintains peak performance while competitors' power curves drop, resulting in 3-5% more energy generated annually.

 

3. Enhanced Durability & 30-Year Warranty

The 2.0mm semi-tempered double-glass construction provides superior protection against PID (Potential Induced Degradation) and harsh environmental stressors like salt mist and ammonia.

  • 12-Year Warranty on Materials and Processing.
  • 30-Year Linear Power Warranty: First-year degradation < 1.0%, with subsequent annual degradation limited to 0.4%. At year 30, the module is guaranteed to maintain 87.4% of its original power.

 

4. Optimized Mechanical Design for BOS Savings

With dimensions of 2384 × 1303 × 33mm and a weight of 37.3 kg, this 66-cell format is optimized for modern tracking systems and fixed racking. The high power density allows for fewer modules per string, significantly reducing BOS (Balance of System) costs, including cabling, racking, and labor.

Superior Yield in High-Heat Environments

For utility-scale developers and EPC contractors, the STC (Standard Test Condition) rating is only the starting point. Real-world performance is defined by how a module handles heat. When solar panels operate under direct sunlight, their surface temperature often reaches 60°C to 70°C, far exceeding the 25°C lab standard.

 

The TWMNF-66HD735 series features a cutting-edge N-type TOPCon architecture that optimizes the Pmax temperature coefficient to a remarkable -0.28%/°C. This is a critical technical advantage over traditional P-type modules (typically -0.35%/°C to -0.39%/°C).

 

What this means for your project ROI:

  • Minimized Power Loss: While standard panels experience significant voltage drops as they heat up, our N-type modules maintain a more stable output curve. At an operating temperature of 65°C, this module provides an additional 3% to 4.5% actual power output compared to industry-average panels.

 

FAQ

Q: What is the first-year and annual degradation rate for the TWMNF-66HD series?

A: Our N-type modules feature zero LID (Light Induced Degradation). The first-year degradation is guaranteed at <1.0%, with a linear annual degradation of <0.4% over 30 years, ensuring at least 87.4% of original power at the end of the term.

Q: Can these modules withstand heavy snow loads or extreme wind?

A: Yes, the module is certified for a front-side static load of 5400Pa (snow/pressure) and a rear-side load of 2400Pa (wind/suction), ensuring structural integrity in harsh weather conditions.

Q: What third-party certifications do you hold for these modules?

A: Our modules are certified by TUV Rheinland/SÜD, CE, and UL. We also actively participate in VeraSol certification through SMQ to ensure compliance with international quality and environmental standards.

Q: How are the modules packaged to prevent micro-cracks during sea freight?

A: We use vertical packaging with 33 pieces per pallet. Each pallet is reinforced with edge protectors and high-tension strapping, then shrink-wrapped to prevent moisture and movement, minimizing the risk of micro-cracks during long-distance transit.

Q: Do you offer technical support for system design or string configuration?

A: Yes, our technical engineering team provides complimentary string calculation reports and layout optimization suggestions to ensure our modules integrate perfectly with your chosen inverter and mounting system.
