Yingli Solar has introduced a new bifacial n-type solar module, Panda 3.0 PRO 590–615 W, which is based on tunnel oxide passivated contacts (TOPCon) solar cells. Reportedly, the front-laminated composite film passivation of TOPCon 24.5 per cent efficient cells helps the module’s ability to use back TOPCon technology to boost the cells’ open-circuit voltage by over 710 mV. There are six versions of the 156-cell Panda 3.0 PRO module, ranging in power output from 590 W to 615 W and in efficiency from 22 per cent to 22.11 per cent. Its short-circuit current ranges from 13.72 A to 14.12 A, and its open-circuit voltage ranges from 54.74 V to 56.44 V. The maximum system voltage is 1,500 V.
A panel weighs 35 kg, and its dimensions are 2,465 mm x 1,134 mm x 30 mm. Additionally, the module has a 2 mm tempered glass panel and an IP67 enclosure. Its working temperature spans from -40 °C to 85 °C, and its temperature coefficient is -0.30 per cent per °Celsius. The new items have a 12-year product guarantee and a 30-year linear power output guarantee. Furthermore, the power output is expected to degrade by 1 per cent in the first year, and will be at least 87.4 per cent of the nominal output power in 30 years.
