Durable construction with 9 reinforced layers provides strong resistance to bending, impact, and harsh weather conditions.
Flexible design allows installation on curved roofs, boat decks, or temporary structures.
Lightweight profile reduces load on structural supports while maintaining efficient energy output.



High light transmittance (95%) and optimized solar cell layout enhance energy generation efficiency.
Pre-drilled mounting holes facilitate fast, secure, and versatile installation.
Stable output under STC conditions, supporting consistent power for on-grid and off-grid systems.
The 300W Weather-Resistant Flexible Solar Panel delivers high-performance solar energy for both marine and rooftop applications. With a slim 2.5mm profile and lightweight design (~3.63kg/m²), it easily adapts to curved or irregular surfaces. Certified to CE and RoHS standards, it ensures safe, reliable operation in extreme temperatures ranging from -40°C to +85°C, making it ideal for outdoor, coastal, or high-altitude environments.
