120W Monocrystalline Flexible Solar Panel, 18V

The 120W Monocrystalline Flexible Solar Panel is a lightweight, high-efficiency solution designed for versatile solar energy applications. Built with advanced monocrystalline silicon cells, this panel achieves up to 24% cell efficiency, delivering superior power generation compared to conventional polysilicon panels. Its flexible, ultra-thin design (just 3mm thick) makes it ideal for installations on curved or uneven surfaces, such as RVs, boats, rooftops, and off-grid solar systems.

Engineered for durability and performance, the 120W Monocrystalline Flexible Solar Panel features a PET-coated surface treated for enhanced wear resistance and optimal sunlight absorption. The IP67-rated junction box ensures waterproof protection, while integrated bypass diodes and overcharge/reverse current protection safeguard your system against electrical faults. The panel operates reliably in extreme temperatures, from -40°C to +80°C, and is built to withstand harsh outdoor conditions.

Installation is simple and efficient, thanks to its lightweight construction (just 2.06 kg) and plug-and-play PV connectors. The panel is compatible with 12V and 24V battery systems, making it suitable for a wide range of uses, including household backup, camping, RVs, yachts, street lighting, and solar power stations. For optimal performance, pair this solar module with a quality charge controller and battery setup.

Solar photovoltaic system manual

Important safety instructions
This manual contains the safe installation and operation instructions of solar modules and solar controller (hereinafter referred to as “controller”).
Please read all instructions and precautions in each product manual and manual carefully before installation and use.

1 Solar module products
a. This product must not be in contact with highly corrosive substances to avoid excessive bending and long-term bending;
b. The solar panel should be prevented from stacking and falling down, the solar flexible panel cannot be disassembled, do not collide with hard objects, avoid trampling, and avoid scratching the surface with hard objects during use;
c. A large number of scratches or dirt on the surface of the solar panel may result in low efficiency of the solar panel, which may seriously cause burnout;
d. The suitable ambient temperature range of solar panels: -20 ℃-80 ℃, do not exceed this range;
e. The solar panel must be installed in an area with good sunlight and no shadow. The solar panel may work in the shaded sunlight for a long time and there may be a risk of burnout;
f. When used in series connection, the “+” of the previous component is connected to the “-” of the next component. The same panel cannot be directly connected to the positive and negative poles.

2 Solar panel connection installation method
When you use a 12V battery, use a parallel connection; when you use a 24V battery, use two serial connections. Please install the solar panel on a smooth surface with good sunlight and no shadow, and try not to install it on uneven areas. Solar panels can be fixed with glue or bolts.
