470W N-Type Double Glass Monofacial LR Traceable Low Carbon 54 Cell Black Frame MC4

This is the low-carbon manufacturing variant of the JA Solar DeepBlue 4.0 Pro JAM54D40-470/LR, a 470W n-type TOPCon 54-cell module built from 108 half-cut cells in a double-glass, monofacial layout, reaching 23.5% module efficiency. Electrical figures are Voc 40.40V, Vmp 33.84V, Isc 14.66A and Imp 13.89A, with temperature coefficients of -0.25%/°C (Voc), -0.29%/°C (Pmax) and +0.045%/°C (Isc) keeping output stable in warm weather. It measures 1762 x 1134 x 30mm, weighs 22.0kg, and is rated for 1500V DC systems. It is certified to IEC 61215 and IEC 61730, and carries a 15-year product warranty and a 30-year linear performance warranty. The low-carbon designation reflects JA Solar's manufacturing process rather than a change to the electrical or mechanical specification.
