Deep Dive: What Makes TF Series Different?
High conversion efficiency
TF series uses the latest high-efficiency monocrystalline cells or Sunpower cells. Monocrystalline cells can achieve efficiencies of up to 22.8% and SunPower cells of up to 24.4%. This flexible solar panel has a higher conversion efficiency and can provide you with more power.
Extreme Durability
Built with advanced polymer composite and ETFE materials, TF panels resist corrosion, UV, and moisture — keeping stable output in salty air, rain, and strong sunlight.
Reinforced for Impact & Foot Traffic
TF Series panels are built with a reinforced multi-layer composite structure that absorbs impact and disperses pressure. With optimized cell spacing and a wear-resistant surface, they withstand physical stress like stepping and handling — without cracks or performance loss.

What Our Partners Are Saying
Sungold TF Series FAQ
Yes. Sungold TF Series flexible solar panels are designed for foot traffic in suitable installation scenarios. Their reinforced composite structure helps distribute pressure and reduce the risk of micro-cracks, making them a practical option for walkable RV roofs, yacht decks, and other marine surfaces where occasional stepping is expected.
Yes. The TF Series is built for demanding outdoor use, including marine environments. It features IP68-level waterproof protection and uses sealed construction designed to resist moisture intrusion, salt mist, and long-term exposure to humid coastal conditions.
TF-M and TF-S are designed for different priorities. TF-M focuses on balanced performance and broader system compatibility, making it a good fit for larger installations. TF-S uses higher-efficiency cell technology and is often preferred when installation space is limited and maximum output per area is more important.
Yes. TF Series panels are made for curved mounting surfaces and are suitable for applications such as RV roofs, boat decks, and other non-flat structures. Their flexible design helps them adapt more easily than rigid panels in installations where weight and contour matter.
TF Series panels use ETFE surface material, which is chosen for better UV resistance and long-term outdoor durability. Compared with lower-grade surface materials, ETFE helps reduce the risk of yellowing, hazing, and surface aging during prolonged sun exposure.
Yes. Sungold supports OEM and ODM customization for the TF Series. Custom options can include panel size, voltage, cable length, connector type, junction box position, mounting details, and private labeling, depending on project requirements and order volume.
Installation should follow the recommended mounting method for the specific project. In many cases, using a bonding solution that leaves a small ventilation gap underneath the panel can help improve heat dissipation and support more stable long-term performance. The exact installation method should match the substrate, environment, and maintenance needs.
The TF Series is developed for outdoor reliability and is associated with testing or compliance references such as waterproof performance, salt mist resistance, and material durability. The exact certification set may vary by model and market, so buyers should confirm the latest available documents for the specific product version they plan to use.
