Solar Module JA Solar JAM54D40-470/LR

With Half-Cut technology, the solar cells are cut in half, which reduces electrical resistance and power losses. The JAM54D40-470/LR uses 108 half-cut monocrystalline cells with 16 busbars, which increases yield and improves performance in partial shading.

In a glass-glass module, the back is not covered with film but with a second glass pane (here 1.6 mm / 1.6 mm). This increases mechanical stability, better protects the cells from moisture, and reduces annual degradation – the basis for the 30-year performance warranty.

Under average irradiation conditions in Austria, a 470 Wp module delivers around 450 to 520 kWh per year. At an electricity price of 25 cents/kWh, this corresponds to savings of about 112 to 130 euros annually per module.

For a typical annual consumption of 4500 to 5500 kWh, you will need about 18 to 24 modules of this type, which corresponds to a system capacity of approximately 8.5 to 11 kWp. The exact number depends on roof orientation, tilt, and desired self-consumption rate.

Yes. The JAM54D40-470/LR is loadable up to 5400 Pa snow load and 2400 Pa wind load and is particularly robust due to its glass-glass construction. Together with the IP68 protection rating of the junction box, it is suitable for snowy and exposed locations in the Alps.
