Yingli Photo voltaic unveils new bifacial n-type TOPCon photo voltaic modules for rooftop purposes.

“Utilizing lighter supplies and frames, the Panda 3.0 Professional 108 cell has some great benefits of lightness and simple set up along with excessive energy, excessive effectivity, excessive bifaciality, and excessive reliability,” stated an organization spokesperson stated. pv journal. “The product is extra appropriate for residential energy crops and different distributed energy crops.”

The 108-cell Panda 3.0 PRO modules can be found in six variations, with energy outputs from 410 W to 435 W and efficiencies from 21.0% to 22.28%. The open-circuit voltage is between 37.75 V and 38.69 V and the short-circuit present is between 13.91 A and 14.22 A. The utmost system voltage is 1,500 V.

The panels measure 1,722 mm x 1,134 mm x 30 mm and weigh 24.8 kg. They characteristic IP67 enclosures and a couple of mm tempered glass. They’ve a temperature coefficient of -0.30% per diploma Celsius and an working temperature from -40 C to 85 C.

The brand new merchandise include a 30-year linear energy output guarantee and a 12-year product guarantee. The 30-year ultimate energy output is assured to be a minimum of 87.4% of the nominal energy output.

“A brand new floor passivation system improves the open-circuit voltage of the cell,” an organization spokesperson stated. “And a low-power laser splitting expertise reduces the lack of cell reducing.”

The modules are based mostly on a TOPCon 24.5%-efficient cells with front-laminated composite movie passivation. It’s reported that the again tunnel oxide passivation contact expertise can enhance the cell open-circuit voltage of greater than 710 mV.

Yingli at present has a TOPCon cell capability of 5 GW. It ought to attain 10 GW subsequent 12 months and 15 GW in 2024. In August, it unveiled the 156-cell Panda 3.0 PRO module with energy outputs of as much as 615 W.
