Double-sided ETFE material and lightweight
The LEE 120w flexible solar panel is specially designed for yachts, RVs and other scenarios. The double-sided ETFE design improves the overall protection level. It is equipped with bypass diodes to avoid hot spot effects. The MC4 connector can easily connect multiple products in series and parallel. The integrated installation design is convenient for customers to install in a variety of ways
Compatible and versatile
The LEE 120W flexible solar panel is engineered for marine and RV applications, providing a reliable and efficient power source. Its double-sided ETFE design ensures excellent protection against weather, corrosion, and physical damage. Equipped with bypass diodes, the panel prevents hot spot effects that could damage the cells. The MC4 connector enables easy series and parallel connections with other solar products. Additionally, the panel’s integrated installation design allows for versatile and convenient mounting options.
Durable and waterproof
The 120W flexible solar panel can be immersed in water for a short time as a whole, so it is more secure to use in extreme weather. This product is designed according to PV standards. Without the protection of glass, the solar panel is still strong and durable and resistant to salt spray.
Specially designed for marine use
The newly designed 120W flexible solar panels, made from advanced materials, are highly resistant to salt spray and corrosion. Additionally, these components are easy to install and ideal for marine use, including yachts and ships. Users can be confident that prolonged exposure to the ocean will not affect the components’ power generation, and installation will not impact the aesthetics of the vessel.




Frequently Asked Questions

To pursue better high weather resistance, high salt spray resistance, high corrosion resistance, and high aging resistance, LEE series solar panels especially uses the design of double-sided ETFE, suitable for marine life.

The use of LEE series solar panel is recommended for yachts, RVs, offshore monitoring, off-grid systems for seaside buildings, plateau equipment, plateau camping, and outdoor travel.

If the modules are exposed to the sun for a long time, the cells are easily exposed to ultraviolet rays and the edges turn yellow, which is a normal phenomenon.

3 years warranty. LEE series flexible solar panels have service life of 15 years

Be careful not to cover the flexible solar panels in a large area during use, which will cause hot spot effect and damage the solar cells.
