Technology Highlight

BYCIUM + Cell

High-density Encapsulation technology with higher power and efficiency and low degradation.

Premium Modules

Better low irradiance response. All JA Solar Deep Blue 4.0 panels lose around 0.29% efficiency for each degree the temperature is over 25°C.

Higher Bifacial Benefits

Better performance under lower temperature and low-light environment. On a typical roof, this increase may be under 10%. But on a reflective white membrane roof it could result in a 27% increase.
