Product Description

The 520W Flexible Solar Panel is a high-efficiency, lightweight, and bendable monocrystalline module designed for versatile solar energy applications. Utilizing advanced thin-film technology with ETFE coating, this ultra-thin (2mm) panel delivers up to 520W output with 22%+ efficiency, making it ideal for curved surfaces, portable setups, and space-constrained installations.

Unlike rigid panels, it's semi-flexible (up to 30-40° bend radius), shatter-resistant, and walkable, perfect for off-grid power generation, marine, RV, and rooftop systems. With superior weather resistance (IP67/IP68) and low-light performance, it maximizes energy harvest in challenging environments while being 70% lighter than traditional glass panels.

Key Features & Benefits

• High Efficiency & Power Output: 520W rated power with 22-23% module efficiency using premium monocrystalline cells. Excellent low-irradiance performance for cloudy or shaded conditions.

 

• Flexible & Lightweight Design: Ultra-thin 2mm profile, bendable up to 30-40°, and weighing only ~8kg-easy to install on curved roofs, boats, or tents without mounting frames.

 

• Durable ETFE Coating: Corrosion-resistant, UV-stable ETFE surface protects against hail, salt, and scratches. Walkable design (up to 120kg load) for marine or rooftop use.

 

• Weatherproof & Reliable: IP67/IP68 rated for waterproof and dustproof performance. Operates in -40°C to 85°C, with anti-PID and low LID for long-term stability.

 

• Easy Installation & Portability: Pre-drilled holes, adhesive backing, or grommets for quick setup. No glass-roll/fold for transport in backpacks or vehicles.

 

• Eco-Friendly & Long Lifespan: Low-carbon footprint, recyclable materials. 25-year power warranty (80% output retention) and 10-year product warranty.

 

• Versatile Compatibility: Junction box with MC4 connectors; integrates with MPPT controllers, inverters, and batteries for 12V/24V/48V systems.

Project Case

Application Scenarios

• RV, Camper, & Camping: Bendable design fits curved RV roofs or tents; lightweight for portable charging of batteries, lights, and devices during off-grid adventures.

 

• Marine & Boat Use: Waterproof and salt-resistant for yacht decks, sailboats, or fishing vessels-power navigation, lights, and pumps without heavy mounting.

 

• Curved Rooftop & Building Integration: Ideal for irregular or metal roofs on homes, greenhouses, or sheds; seamless BIPV (Building-Integrated Photovoltaics) for urban solar energy.

 

• Portable & Emergency Power: Rollable for backpacks or emergency kits; quick setup for disaster relief, hiking, or remote work sites to charge phones, laptops, or medical devices.
