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.

Frequently Asked Questions

How flexible is this 520W panel?
The panel is semi-flexible and can bend up to 30-40 degrees, making it ideal for slightly curved surfaces like RV roofs, boat decks, and curved architectural structures.
Can I walk on the solar panel?
Yes, thanks to the durable ETFE coating, the panel is walkable and can support a load of up to 120kg. However, we recommend avoiding stepping directly on the junction box or connection cables.
Is it completely waterproof for marine use?
Absolutely. The panel is IP67/IP68 rated, meaning it is fully sealed against dust and can withstand rain, salt spray, and even temporary submersion, making it perfect for yachts and sailboats.
How does the weight compare to glass panels?
This flexible panel is approximately 70% lighter than traditional glass solar panels. At only 8.6kg for a 520W output, it significantly reduces the structural load on rooftops and vehicles.
What kind of maintenance is required?
Minimal maintenance is needed. Because of the ETFE non-stick surface, rain usually washes away most dirt. Occasional wiping with a soft damp cloth will ensure maximum energy efficiency.
Is it compatible with 12V or 24V battery systems?
Yes, it features standard MC4 connectors and is compatible with most MPPT charge controllers and inverters for 12V, 24V, and 48V off-grid systems.
