430W Flexible Solar Panel: High-Efficiency Bendable Power for Curved Surfaces

Experience the future of solar integration with our 430W Flexible Solar Panel, engineered to deliver robust power on curved surfaces where traditional rigid panels fail. Combining a high 23.5% conversion efficiency from advanced TOPCon cells with an ultra-thin 2.7mm profile, this module is the ideal solution for seamless integration on RV roofs, marine vessels, and commercial buildings. Certified by TÜV SUD to withstand harsh conditions—including 25mm hail impacts and 5400Pa snow loads—it offers a perfect blend of performance, durability, and aesthetic discretion.

Product Introduction & Key Features

• High Power & Superior Efficiency: Generate 430W of clean energy with industry-leading 23.5% module efficiency, maximizing output even in limited spaces.

• True Flexibility & Ultra-Thin Design: With a slim 2.7mm thickness and flexible substrate, it conforms perfectly to curved surfaces up to a 30-degree arc, enabling direct, low-profile installation.

• Advanced TOPCon Cell Technology: Features 108 N-Type TOPCon cells that ensure higher energy yield, better performance in high temperatures, and lower degradation over time compared to conventional PERC cells.

• Exceptional Durability & Certification: Rigorously tested and certified by TÜV SUD, it withstands hail impacts (25mm at 32m/s), heavy snow loads (5400Pa), and strong winds (2400Pa).

• Lightweight & Cost-Effective Installation: The frameless design and minimal weight (~5.6kg) eliminate the need for heavy racking, significantly reducing structural load and installation time and costs.

Technical Deep Dive: How It Works

This panel utilizes state-of-the-art TOPCon (Tunnel Oxide Passivated Contact) cell technology. A key differentiator is the ultra-thin silicon oxide layer and doped poly-silicon layer on the cell's rear surface. This structure dramatically reduces charge recombination, allowing the cell to operate at a higher voltage and efficiency. The excellent temperature coefficient of -0.26%/°C for Pmax means the panel maintains more of its rated power on hot days, a common issue with standard panels.

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.

Frequently Asked Questions (FAQ)

Q: What is the maximum bending angle for safe installation?
A: The panel can be safely bent to a maximum of 30 degrees. Exceeding this may cause micro-cracks and void the warranty.

Q: How do I mount this flexible panel?
A: We recommend using a high-strength, UV-resistant adhesive (like 3M VHB tape) for direct bonding. Mechanical fasteners can be used as a supplement in high-wind areas.

Q: Can it handle snowy conditions?
A: Yes, with a 5400Pa front-side load rating, it can withstand significant snow accumulation, equivalent to over 2 feet of heavy, wet snow.

Q: How does the temperature coefficient benefit me?
A: The low-temperature coefficient of -0.26%/°C for power means you will lose less energy output on a hot summer day compared to panels with a higher coefficient (e.g., -0.35%/°C), resulting in more stable annual energy production.

Important Installation Notes

• Ensure the mounting surface is clean, dry, and free of sharp protrusions.

• Leave a small air gap (≥10mm) between the panel and the mounting surface for passive cooling.

• Do not install in a manner that stresses the junction box or cables.

• Use appropriate fusing and a charge controller compatible with the panel's high current and VOC.

• We recommend professional installation for optimal performance and safety.
