Product Description
70W / 75W / 80W Durable ETFE and CIGS Cell Laminate Flexible Solar PV Sheets (FLEX-03NS)
Our flexible solar panel adopts advanced CIGS technology, achieving aperture efficiency as high as 17%, rivaling traditional rigid glass panels while maintaining complete flexibility.
Technology & Production
Starting with high-grade stainless steel foil, we utilize an advanced PVD semiconductor deposition process to produce the world's most stable flexible CIGS cells. The cell structure is protected by a specialized plastic-cell interconnect mesh-wire system and high-performance water barrier plastics. An internal aluminum film in the backsheet prevents water transmission, ensuring the longevity and power of the stainless steel CIGS cells.
Key Benefits
⚖️ Ultra Light Weight
Less than 2.4 kg/m² (<0.5 lb/ft²). Ideal for structures with low dead load limits like greenhouses or RVs.
⚡ High Efficiency
The highest efficiency thin-film CIGS modules today, providing 4x the power generation per kilogram compared to silicon.
🛠️ Easy Installation
Simple peel-and-stick application. No penetrations or racking required, reducing leak risks and BOS costs.
🌀 Superior Flexibility
Conforms easily to curved surfaces where traditional rigid panels cannot be installed.
🛡️ Disaster Resistant
Shatterproof and resistant to debris. Offers excellent wind and seismic resistance due to direct surface adhesion.
📡 Industry Reliability
Features a unique redundant interconnect design to ensure leading performance and reliability.

Frequently Asked Questions
1. What makes CIGS technology different from standard solar panels?
CIGS (Copper Indium Gallium Diselenide) technology allows for high efficiency (up to 17%) in a flexible, thin-film form factor. Unlike rigid panels, it can be applied to curved surfaces and is significantly lighter.
2. How are these flexible solar sheets installed?
The FLEX-03NS series uses a "peel-and-stick" application. This eliminates the need for heavy racks or roof penetrations, making it faster to install and safer against potential roof leaks.
3. Can these panels withstand harsh weather or natural disasters?
Yes. Being only 2.5mm thick and adhering directly to surfaces, they offer excellent wind and seismic resistance. They are also shatterproof and will not break if struck by debris.
4. What is the weight advantage of using these modules?
These modules weigh less than 2.4 kg/m², which is substantially lighter than traditional silicon panels. This makes them perfect for roofs with low load capacity or vehicles like trucks and RVs.
5. Are these panels suitable for curved surfaces?
Absolutely. The modules conform to curved surfaces, enabling solar power generation on structures where traditional rigid panels simply cannot be mounted.
6. What type of warranty is provided with the FLEX series?
The product comes with a 5-year workmanship warranty and a tiered 10/25 year warranty against power loss to ensure long-term reliability.
