It produces from the light reflected from underneath as well, not only from above: 625 W on the front, 23.1% efficiency, 80% bifaciality and up to 688 W equivalent on reflective ground.
It is a large, bifacial panel from the Trina Vertex N series. Bifacial means that it has glass on the back as well and converts into current also the light that is reflected from the ground towards the rear side of the module - from light gravel, white membrane or snow. The construction is solid, with two sheets of heat-strengthened glass and a thick aluminium frame, designed for ground and hall installations, not for small houses. It is the typical panel for photovoltaic parks and commercial projects.
On the front, the module delivers 625 W at an efficiency of 23.1%; with reflective ground, the gain from the back raises the equivalent power to 656 W for a plus of 5% and to 688 W for a plus of 10%, values that the datasheet gives explicitly for sizing the inverters. At NOCT, that is at the real temperature in the field, the module gives 478 W. At 2382 x 1134 x 30 mm and 33.7 kg, the panel is installed by two people and requires appropriately sized structures; it withstands 5400 Pa positive load and 2400 Pa negative load. It is declared resistant to salt mist, ammonia, sand and high humidity, so it works by the sea, next to livestock farms or in dusty areas. The warranty is 12 years on the product and 30 years linear on the power, with a maximum of 1% degradation in the first year and 0.40% per year afterwards, that is a minimum of 87.4% at 30 years.

Specifications confirmed from the manufacturer's datasheet
TSM-NEG19RC.20-625 is the top bin of the Trina Vertex N series (595-625 W), a double-glass bifacial module with monocrystalline N-type i-TOPCon cells in 210R format, cut in half and arranged in 132 half-cells. The construction uses two sheets of 2.0 mm heat-strengthened glass - the front with an antireflective coating and high transmission, the back with a white grid - POE/EVA encapsulation and a 30 mm anodised aluminium frame.
At STC the module delivers 625 W on the front, with Vmp 41.7 V, Imp 15.00 A, Voc 49.9 V and Isc 15.92 A, at an efficiency of 23.1%; at NOCT the values are 478 W, 39.1 V and 12.22 A. The bifaciality factor is 80% +/- 5%, and the datasheet also includes sets of values for a rear gain of 5% and 10% (668-688 W total equivalent power), useful for sizing the inverters in ground-mounted projects. The SMBB (super multi-busbar) technology reduces the series resistance and improves light capture, and the non-destructive cutting of the cells limits microcracks.
The temperature coefficients are -0.29 %/deg C for Pmax, -0.24 %/deg C for Voc and +0.04 %/deg C for Isc, with a NOCT of 43 +/- 2 deg C. The maximum system voltage is 1500 V DC, the maximum string fuse 35 A, and the admissible mechanical load 5400 Pa positive and 2400 Pa negative. The junction box is IP68, the connectors TS4 PLUS / TS4, the cable 4.0 mm2. The module is certified IEC 61215 / IEC 61730 / IEC 61701 / IEC 62716 / UL 61730 and has declared resistance to salt mist, ammonia, sand and high humidity. Weight 33.7 kg.
More energy from the same roof area: 600 W from a single module, at 23.2% efficiency, with the contacts moved to the back for a fully active front face.
Fewer parts and faster installation for the same power: 615 W per module, at 23.8% efficiency, in a panel of 27 kg and 2278x1134x30 mm.
455 W and 22.8% efficiency in a 21.5 kg panel, with cells without metal contacts on the front and low losses in heat.
The front of the panel has no metal stripes: 450 W, 22,6% efficiency and only 21,5 kg, with good behaviour under partial shading.
