- Photoelectric efficiency and temperature management
|
characteristic |
PA219 |
TF Series |
|
Standard efficiency |
22.7% (monocrystalline silicon) |
22.8% (single crystal) 24.4% (SunPower) |
|
Hot spot management |
Borderless anti-PID design |
Optimize circuit anti-shadowing |
|
High temperature attenuation |
Slightly faster than traditional boards (needs quality assurance hedging) |
Significantly affected by environmental dirt |
Key insights:
TF series is more efficient under ideal lighting, but PA219 is more stable in high temperature/partial shadow environment
- Installation adaptability: when flexibility meets curved surface

- Ultimate Selection Guide: Matching by Scenario
Choose PA219 when you need:
- Permanent curved installations (curved roofs/yacht decks)
- Fight against extreme climate (blizzard/salt spray/chemical plants)
- Ultra-low load-bearing limit (old building renovation)
- Zero light pollution requirement (airports/ecological protection areas)
Choose TF series when you need:
- Mobile power supply for RV/backpacking expeditions
- Extreme lightweight (when every gram counts)
- Instantaneous and efficient power generation (SunPower battery peak advantage)
- Fast stain self-cleaning (dusty environment)
- Shanggu Optoelectronics' Flexible Technology Philosophy
These two products represent our in-depth thinking on different energy scenarios:
PA219 redefines "flexible durability" with military-grade protection - allowing solar energy to conquer traditional restricted areas
TF series achieves "energy invisibility" with breakthroughs in materials science - making electricity integrated into life like fabric
Your scenario determines the choice:
Want to conquer extreme environments? PA219 is your silent steel guard
Want energy to follow you everywhere? TF series becomes your personal energy steward
