Longi has unveiled its new Hi-Mo 7 PV module for large-scale and C&I applications. The new product is based on tunnel oxide passivated contact (TOPCon) cells, M10 wafers and high performance hybrid passivity dual junction technology. The PV module weighs 31.8 kg and has dimensions of 2,278 mm x 1,134 mm x 30 mm. It has an IP68 rating, 2.0 mm dual glass and an anodised aluminium frame. The temperature coefficient is -0.28 per cent per °C. The new series has seven different versions with power outputs 560-590 W. The power conversion efficiency varies between 21.7 per cent and 22.8 per cent. The short-circuit current varies between 13.89 A and 14.1 A, and the open-circuit voltage between 50.89 V and 51.63 V. The panels used in PV systems have a maximum voltage of 1,500 V. For 88.18 per cent of the initial yield, the company provides a 12-year product guarantee and a 30-year power output guarantee.
