Chinese PV module manufacturer TCL Sunpower has expanded its P Class portfolio with two new series of shingled modules aimed at residential and commercial rooftop installations. The P Class RES Black line offers powers from 465 W to 475 W with efficiency up to 23.8%, while the P Class COM range delivers 580 W to 600 W and efficiency up to 24%.
Both series are designed for high-density roof applications and feature a multi-busbar, shingled cell architecture aimed at improving shade tolerance and mechanical resilience.
“This new product line is an upgrade from our shingle range that we launched four years ago,” said Irene Miranda, the company’s sales representative for Italy. pv magazine at the Key Energy fair in Rimini, Italy. “We increase module efficiency while maintaining the same dimensions. In addition, the module is particularly resistant to salt fog.”
The P Class RES Black series is offered in three power classes – 465 W, 470 W and 475 W – with module efficiencies of up to 23.8%. The 475 W variant provides an open-circuit voltage of 54.0 V and a short-circuit current of 10.91 A.
Designed for residential roof applications, the modules measure 1,860mm x 1,134mm x 30mm and weigh 24.2kg. They are constructed with 2.0mm heat strengthened glass and framed in black anodized aluminum. The junction box has an IP68 rating and the temperature coefficient is -0.29%/C. It is suitable for a maximum system voltage of 1500 V DC and operates within a temperature range of -40 C to 85 C.
For commercial and industrial applications, the P Class COM bifacial series has output levels of 580 W, 590 W and 600 W, with efficiencies up to 24%. At STC, the 600 W version achieves a maximum power of 600 W, supported by an open-circuit voltage of 48.5 V and a short-circuit current of 15.73 A. The module operates at a maximum supply voltage of 40.7 V and a maximum power current of 14.71 A.
The commercial modules measure 2,278mm x 1,134mm x 30mm and weigh 32.5kg, reflecting their larger size and higher power density. As with the residential line, they feature 2.0mm heat-resistant glass and IP68-rated junction boxes.
Both panels have a temperature coefficient of -0.29%/C and promise a minimum guaranteed efficiency of 99% in the first year and a maximum annual degradation of 0.4%. They come with a 30-year product warranty and a 30-year performance warranty.
According to the manufacturer, both panels have been tested to withstand mechanical loads of up to 5,400 Pa at the front and 2,400 Pa at the back, making them suitable for roofs exposed to heavy snowfall or strong wind loads.
