JA Solar JAM66D45 LB 625W N-Type Bifacial Dual Glass Solar Panel, 23.3% Efficiency

JA Solar JAM66D45 LB 625W N-Type Bifacial Solar Panel

The JA Solar 625W solar panel price in BD is on this page. JA Solar is a global top-tier module manufacturer, and the JAM66D45 LB is one of its high-output N-type bifacial dual-glass modules, putting 625W into a single panel for fewer panels, less mounting hardware and faster installation.

N-type cells, high efficiency

The panel uses 132 N-type monocrystalline cells arranged 16 x 2 in a half-cell layout, reaching module efficiency of up to 23.3%. N-type technology keeps output steadier in hot weather and loses less capacity over the years than older P-type designs.

Bifacial dual glass

• Generates extra energy from light reflected onto the rear side
• Glass on both faces resists moisture, cracking and corrosion
• 2.0mm glass for strength with lower weight than thick single glass
• Class II protection with an IP68 junction box and three bypass diodes

Electrical figures

At 625W, the maximum power voltage is up to 40.70V and maximum power current is up to 15.48A. Because current is high, make sure each inverter MPPT input accepts at least about 16A, and check string voltage limits against the inverter's maximum PV input voltage.

Fewer panels for the same power

A 3.6kW array needs only six of these panels instead of nine or ten older 370–400W panels. That saves roof space, mounting rails, clamps and cabling, and shortens installation time.

Installation tips

Face the panels south at a tilt of around 20–25° for Bangladesh, raise them above the roof for cooling and rear-side gain, and keep the glass clean through the dry season. A qualified installer should design the strings and protection.
