JA Solar bifacial glass-glass modules - maximum energy yield meets stability
JA Solar 's bifacial glass-glass modules combine two high-performance technologies:
Bifacial cells that convert light into electricity from both sides, and a glass-glass structure that protects the sensitive solar cells all around. This combination makes the modules particularly durable, efficient and ideal for professional installations with high demands on yield and service life.

Technology in focus: Why bifacial and glass-glass?
- Bifacial cell technology: The back of the modules is active - it uses reflected light from the ground, roofs or water surfaces. Depending on the substrate, additional yields of up to 20 % are possible.
- Glass-glass structure: Two 2 mm thick layers of glass enclose the solar cells on both sides. This protects against moisture, temperature fluctuations, mechanical loads and increases fire safety.
- Longevity: Only 0.4 % degradation per year and up to 30 years linear performance guarantee - ideal for systems with a long service life.
- PID resistance & durability: Certified for environments containing salt spray and ammonia - also suitable for coastal regions and agriculture.
