SOLARKIT reviews

The LONGi Hi-MO 7 445 Wp panel is one of the manufacturer's most advanced solutions, based onn-type HPDC cell technology. This cell shape improves light capture and reduces losses.
The bifacial (double-sided) design allows the panel to generate energy on the back side as well, with up to 80±5% efficiency on the rear side. This is particularly useful in bright, reflective environments such as snow or gravel.
The 445 Wp power output and 22.8% module efficiency are among the best in its class.
