The Gokin GEM G12R/108D 500W Full Black Solar Panel is a modern, high-performance N-Type TOPCon solar panel module that combines high energy output with a premium, all-black design. With a 500 W nominal power output and a 22.5% module efficiency, it is an excellent choice for residential and commercial solar systems where aesthetics are an important consideration alongside the efficient use of available roof space.

The GEM series’ advanced N-Type cell technology ensures low degradation, favorable thermal properties, and long-term performance. In addition, the module is bifacial, with a glass-on-glass design, so under suitable installation conditions, it can also harness light falling on its rear side to generate energy.

N-Type TOPCon cell technology

The Gokin GEM G12R/108D uses state-of-the-art N-Type TOPCon cells. As a result, the module offers favorable degradation and temperature characteristics, while delivering high power output despite its relatively compact size.

Another advantage of N-Type technology is its increased resistance to LID and LeTID degradation. As a result, the module is able to maintain its performance over a longer period of time, which is particularly important for solar power systems designed to operate for several decades.

500 W power output and 22.5% module efficiency

The module's rated power is 500 W, while its efficiency is 22.5%. The high module efficiency makes it possible to install a higher total solar panel capacity on a given roof area.

This is particularly advantageous when roof space is limited. Furthermore, thanks to the higher power output per module, the same system output can be achieved using fewer solar panels.

Full Black – Premium Look

The Full Black design gives the module a uniform, dark appearance. The black cell surface and black frame create a modern, clean overall look, which is why the Gokin GEM series is particularly well-suited for the rooftops of modern single-family homes and upscale buildings.

In this way, the solar panel not only functions as an energy-generating device but can also serve as an aesthetically harmonious part of the building.

Double-sided, glass-to-glass design

The Gokin GEM G12R/108D bifacial solar panel—meaning that, under the right conditions, the back of the module can also harness reflected sunlight. The manufacturer specifies a bifacial factor of 80 ±5%.

In addition, the module features a double-glass design: both the front and back sides are made of 1.6 mm thick glass. This design provides durable protection for the solar cells while contributing to a long service life.

Favorable thermal properties

The power output of solar panels naturally decreases as the cell temperature rises. The Gokin GEM G12R/108D has a temperature coefficient of Pmax of -0.29%/°C .

As a result, it ensures favorable energy-generation characteristics even at higher operating temperatures. This is particularly important during the summer months, when the surface temperature of the solar panel can significantly exceed the ambient temperature.

Durable mechanical design

The module measures 1961 × 1134 × 30 mm and weighs 22.2 kg. The anodized aluminum alloy frame provides adequate mechanical stability, while the module's design is capable of withstanding heavy loads.

The maximum static load capacity of the front side is 5,400 Pa, while that of the back side is 2,400 Pa. Furthermore, the module meets the requirements of a hail test conducted with hailstones 25 mm in diameter traveling at a speed of 23 m/s.

IP68 junction box and 1,500 V system voltage

The module features an IP68-rated junction box , providing adequate protection against the effects of outdoor environments.

The maximum system voltage is 1,500 V DC, while the maximum in-line fuse rating is 30 A. This makes the module suitable for use in both modern residential and larger solar power systems.

Low degradation and a long warranty

Gokin offers a 15-year product warranty and a 30-year linear performance warranty for the GEM G12R/108D series .

In the first year, the maximum power degradation is 1%, and thereafter, the manufacturer estimates an annual degradation of no more than 0.4% between the 2nd and 30th years. As a result, the guaranteed power output at the end of the 30th year is 87.4%.
