Product information:

The ASWS Strong StyleHJT double glass module scores with an output of 420 watt and the use of so-called heterojunction technology. It features 108 HJT solar cells, original Stäubli MC4 connectors and the fire protection class A.

Due to the use of bifacial solar cells in a glass composite (with a bifacial factor of 90±5%), double-sided power generation is possible. Under standard measurement conditions (BSTC), the Strong StyleHJT solar module generates up to 470 watt.

The ASWS-420-MH108N-BG glass-glass solar module is suitable for various applications and especially for installation surfaces with high fire protection requirements. Therefore, the ASWS Strong StyleHJT is very popular in the planning of solar systems for private houses (e.g. terraced houses).
