GCL Solar 590 Wp Panel; NT10/72GDF-590 Wp Bifacial Dual Glass Monocrystalline Module (720)

The GCL NT10/72GDF-590 is a 590Wp bifacial dual glass monocrystalline module built on n-type cell technology, delivering 22.84% module efficiency across 144 half-cut cells. N-type construction gives better reliability and markedly lower LID and LETID than p-type alternatives, so output holds up over the life of the plant. A -0.29%/°C Pmax temperature coefficient keeps performance strong on hot days, and bifaciality of 80±5% adds rear-side yield — at a 10% irradiance ratio the module produces 637.5W. Both faces use 2.0mm glass: anti-reflection coated on the front, heat-strengthened on the back, set in an anodized aluminium frame rated to 2400Pa wind and 5400Pa snow load. The IP68 junction box carries three bypass diodes with MC-compatible connectors and 4.0mm² cable. Salt mist, ammonia corrosion and sand blowing tested to IEC 61701, IEC 62716 and DIN EN 60068-2-68, making it suitable for coastal, agricultural and desert sites. Every module passes 2×100% EL inspection. Rated for 1500V DC systems across -40°C to +85°C, with a 0~+5W positive power tolerance. Backed by a 12-year product warranty and 30-year linear power warranty at 0.40% annual degradation, retaining 87.4% at year 30, with additional insurance backed by Swiss RE. Manufactured under ISO 9001, ISO 14001 and ISO 45001.
