GCL Solar 625 Wp Panel; NT12R/66GDF-625Wp Bifacial Dual Glass Monocrystalline Module (720)

The GCL NT12R/66GDF-625 is a 625Wp bifacial dual glass monocrystalline module built on n-type cell technology and 210R large-format wafers, delivering 23.14% module efficiency — the top of its series — across 132 half-cut cells. The larger wafer format cuts the number of support brackets, cable runs and land area needed per megawatt, lowering overall LCOE on utility-scale ground mount. Non-destructive cutting reduces micro-crack risk during manufacture, and n-type construction gives better reliability with markedly lower LID and LETID. 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 675.2W. Both faces use 2.0mm heat-strengthened glass 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.
