Bisol unveils its new half-cut cell solar panels for residential use

Bisol has announced a new residential PV module series developed with M10, half-cut cells and 10 thin-wired busbars. The modules are available in 400 W, 410 W and 420 W versions. Their power conversion efficiencies range from 20.5 per cent to 21.5 per cent. The open-circuit voltage is between 37 V and 37.4 V and the short-circuit current is between 13.74 A and 14.06 A. The panels can function at operating temperatures of -40 °C to 85 °C with a maximum system voltage of 1,500 V. They have a size of 1,722 mm x 1,134 mm x 30 mm, weigh 22 kg and are fabricated with 108 half-cut PERC cells. The new products also feature 3.2 mm anti-reflective tempered glass coating, and a junction box with an IP68 rating. Their temperature coefficient is -0.34 per cent °C. The company provides a 25-year linear power output guarantee as well as a 15-year product guarantee for the modules. The degradation rate in the first year is purportedly 3 per cent.
