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
Answer: Absolutely. Unlike standard flexible panels that develop "death by a thousand cracks" from walking, the TF Series is built with a reinforced composite core.
It’s designed to absorb and redistribute pressure.
We’ve stress-tested this over 14,700 steps; the result was zero structural damage and negligible power loss (<3%).
It’s a "worry-free" solution for yacht decks and high-traffic RV roofs.
Answer: We engineered the panel for movement.
By combining a high-flex polymer backsheet with optimized cell interconnects, the TF Series thrives in high-vibration environments.
It can maintain a 260mm arc indefinitely without the cells snapping—making it the go-to choice for curved surfaces that are always in motion.
Answer: No. We skip the cheap PET materials used in entry-level panels and use top-tier ETFE.
It’s chemically inert and UV-stable.
This means you won’t see the typical "clouding" or browning even after years of exposure to intense sunlight.
The transparency stays high, and so does your power output.
Answer: It’s built for the ocean.
The TF Series is IP68 rated and has survived 672 hours of intensive salt mist testing (IEC 61701) with almost no degradation.
We’ve sealed every layer to ensure that salt-air corrosion never reaches the internal circuitry.
Answer: Heat is the enemy of efficiency, so we use high-grade, heat-resistant substrates.
For the best results, we recommend a "ribbon-bond" installation using 3M VHB tape.
This creates a small 3mm air gap underneath.
This simple setup keeps the cells roughly 15°C cooler than direct gluing, significantly boosting both performance and the panel's lifespan.
Answer: Most of our B2B business is custom.
We can adjust dimensions, shift junction box locations (front or rear), and pre-apply adhesives or stainless eyelets to fit your production line.
Our goal is to make the panel "plug-and-play" for your specific vehicle or boat model.
