Trinasolar has launched its latest Vertex S+ G3 series modules for residential and C&I applications
It also promoted Vertex N G3 series products for utility-scale applications
The former modules share a common dimension of 1,762 × 1,134 × 30 mm, while the latter have dimensions of 2,384 × 1,303 × 33 mm and 2,382 × 1,134 x 30 mm
During the KEY Energy Expo in Italy, Trinasolar, a well-known TOPCon PV maker, unveiled its latest modules, aimed at residential, commercial & industrial (C&I), and utility applications.
For residential and C&I applications, the company promotes 3 new Vertex S+ G3 series modules.
The NEG9RP.28Z model, equipped with 144 half-cut cells and a dual-glass configuration, is rated at 485 W power output and 24.3% efficiency at standard test conditions (STC). Without sharing data, the company states that its low open-circuit voltage (Voc) and high short-circuit current (Isc) support a longer but reduced fewer-string configuration compared to its peers for the same plant capacities (kW or MW). This, in turn, helps installers optimize balance-of-systems (BoS) components, such as combiner boxes, array junction boxes (AJBs), and surge protection devices (SPDs).
The company promotes the NEG9R.25Z series monofacial module for residential rooftop applications, featuring full-black aesthetics. This module is rated for a maximum power output of 480 W and an efficiency of 24.0%. The company states that it maintains consistent performance at high operating temperatures, which are common in monofacial rooftop installations with very narrow rear free spaces for proper ventilation. However, the company’s press release didn’t share its rated operating temperature range or maximum hotspot temperature. It also performs satisfactorily in low or diffuse light conditions, such as early morning, overcast conditions, or late afternoon. While the baseline data for this comparison are unknown, we assume this is due to the cell’s high shunt resistance (Rsh).
For installations in challenging environments with high wind and frequent hailstorms, the company promotes the Shield (NED9R.28Z) series module. While the datasheet of the currently available models suggests that it uses 2 mm front and rear glass (heat-strengthened), Trinasolar doesn’t disclose the maximum front and rear side loading capacities.
All these displayed modules have common dimensions of 1,762 × 1,134 × 30 mm and carry warranties of up to 25 years for the product and 30 years for performance.
On the large-scale utility installation side (tracker-based), the company offers NEG21C.20Q and NEG19RC.20Q models from the Vetex N G3 series. The former product, comprising 132 M12 (210 × 210 mm) half-cut cells and a double-glass (front and rear) design, is rated at a power output of up to 760 W and an efficiency of up to 24.5%. It measures 2,384 × 1,303 × 33 mm. The latter, with a smaller size of 2,382 × 1,134 × 30 mm, boasts a maximum power output of 670 W and an efficiency of 24.8%, suitable for 1P tracker systems. Both modules, however, feature maximum bifaciality of 85% and offer a performance warranty of up to 30 years.
According to the company, these modules will be commercially available in H2 2026.
