Flexible solar panel 125W monocrystalline for 12V battery, camping, boats, RV

The flexible solar panel 125W is a practical solution for those who want an independent power source for travel, camping, or boating. Using 18BB monocrystalline technology, this panel provides high efficiency and stable charging for a 12V battery. The flexible body makes it easy to attach to uneven surfaces such as boat decks, RV roofs, or tents.

Flexible solar panel - key features

• 18BB monocrystalline technology — Higher energy generation efficiency even with limited installation space.
• Flexible body — Allows bending the panel to match the surface shape, making it suitable for boats, cars, and tents.
• Japanese ETFE film — Resistant to corrosion, water, snow, and small hail, suitable for outdoor use.
• Built-in bypass diodes — Protects the circuit and improves performance under partial shading conditions.
• Pre-wired cables — Includes 2.5MM2 cables with connectors, approximately 900MM long, making installation easier.
• 6 mounting holes on the back — Allows for quick and reliable attachment of the panel to the desired surface.
