440W Flexible Solar Panel: High-Efficiency Bendable Power Solution

Experience unparalleled solar performance with our 440W Flexible Solar Panel, designed for applications where both high power output and surface adaptability are essential. This premium solar module combines exceptional 440W power output with advanced TOPCon cell technology, achieving 23.5% conversion efficiency in an ultra-thin 2.7mm profile. Perfect for curved RV roofs, marine applications, and commercial installations where traditional rigid panels cannot be used. With TÜV SUD certification for hail impact resistance and 5400Pa load capacity, this panel delivers reliable performance in the most demanding environments while maintaining a discreet, low-profile appearance.

Key Features & Benefits

• Maximum Power Output: 440W rating provides superior energy generation for power-intensive applications, making it ideal for off-grid systems and large RV installations

• Advanced TOPCon Technology: Featuring 108 N-type TOPCon cells that deliver higher efficiency and better temperature performance than conventional solar cells

• Ultra-Thin Flexible Design: At just 2.7mm thick, this panel conforms perfectly to curved surfaces without compromising structural integrity or performance

• Exceptional Durability: Certified to withstand 25mm hail impacts at 72mph, 5400Pa snow loads, and extreme weather conditions

• Easy Installation & Cost Savings: Frameless design and adhesive mounting options eliminate need for heavy racking systems, reducing installation time and costs by up to 50%

Technical Excellence & Performance

This solar panel utilizes cutting-edge TOPCon (Tunnel Oxide Passivated Contact) cell technology, which incorporates an ultra-thin silicon oxide layer and doped polysilicon layer on the cell's rear surface. This advanced architecture minimizes electron recombination, enabling higher open-circuit voltage and superior performance in high-temperature environments. With a temperature coefficient of -0.26%/°C for maximum power, the panel maintains optimal output during peak summer temperatures where conventional panels experience significant efficiency drops.

Application Scenarios

The versatility of this flexible 120W panel opens up a wide array of applications across diverse sectors:

• Building & Construction Integration: Ideal for commercial and industrial roofs with limited load-bearing capacity, where its lightweight nature eliminates structural concerns. It is also the perfect solution for curved and special architectural structures, such as arched canopies, awnings, and heritage buildings, enabling seamless solar integration without compromising design.

• Transportation Infrastructure: Can be deployed on highway slopes and noise barriers, turning underutilized public infrastructure into efficient power-generating assets, contributing to smart city and greenway projects.

• Agriculture & Aquaculture: Excellently suited for PV agricultural greenhouses and flower markets, where its semi-transparent properties and light weight allow for simultaneous crop growth and solar generation, reducing energy costs for climate control.

• Portable & Mobile Energy Systems: Perfect for balcony PV systems (BIPV) for urban residents, and for integration onto the roofs of vehicles, buses, and train carriages. This provides auxiliary power for air conditioning, lighting, and electronic devices, enhancing energy independence for mobile applications.

Our Advantages

We provide cutting-edge solar solutions that redefine where and how solar power can be deployed. Our core advantages are rooted in superior engineering and a deep understanding of real-world application challenges:

• Ultimate Lightweight & Flexible Design: Our modules boast an exceptionally low weight of just 2.7kg/m² (approximately 30% of traditional glass modules) and an ultra-thin profile of only 2.7mm. This revolutionary form factor eliminates concerns for weight-restricted roofs and enables perfect conformity to various curved surfaces.

• Rackless Installation & Superior Convenience: The flexible and lightweight nature allows for installation typically without complex metal racking systems. The modules can be directly adhered or simply fastened, significantly reducing installation complexity, labor costs, and time, offering unparalleled ease of deployment.

• Proven High Reliability: The product has successfully passed multiple stringent TÜV SÜD tests, including hail impact, mechanical load, and humidity freeze tests. This ensures stable power output and long-term performance durability even in harsh environments, providing you with complete peace of mind.
