Smart Insights (data-driven)
  • At 22.5% efficiency, this panel is on par with typical TOPCon 700-750W modules
  • Power density of 225.3 W/m² is 3.5 W/m² below TOPCon 700-750W median (228.8 W/m²) - needs more roof space
  • Temperature coefficient of -0.29%/°C matches the TOPCon 700-750W median
  • #3342 for efficiency, #1739 for temperature performance out of 11672 panels

Show series description

The JA Solar JAM66D46 LB series is designed for maximizing yield in installations where every square meter counts and ensuring stable performance year after year – especially on warehouse roofs, large industrial halls, and extensive PV farms. The application of N-type TOPCon cells translates to high resistance to light-induced degradation, facilitating predictable energy production over the long term. The bifacial double-glass construction allows for the use of reflected light while simultaneously enhancing the module's resistance to environmental factors critical for ground and industrial applications. The half-cut layout improves performance under partial shading and minimizes losses in practical installation conditions. It also helps that the better temperature coefficient supports efficiency during hot periods, and the refined performance under low-light conditions is another advantage. Compared to many standard PERC modules, JAM66D46 LB offers a more future-oriented technology and a more favorable long-term production profile.
