JA Solar JAM66D45-630/LB Photovoltaic Module (630 W, N-type)

The JA Solar JAM66D45-630/LB solar module is a 630 W bifacial glass-glass panel based on monocrystalline half-cut N-type cells. The 16-busbar (16BB) design ensures high efficiency and reduced degradation over its operational lifespan.

The JA Solar JAM66D45-630/LB solar module features N-type cell technology with 16 busbars (16BB), achieving a nominal power output of 630 W. The bifacial design with 2.0 mm glass on both sides increases the total energy yield by utilizing ground-reflected radiation. The panel stands out with a low temperature coefficient of power at -0.290 %/°C, resulting in stable performance at higher temperatures. The device is designed for integration with photovoltaic systems up to a maximum voltage of 1500 V DC.
