The GKA210N132 series delivers a maximum power output of 750 W with module efficiency reaching up to 23.18%. These figures result from the use of N-type TOPCon cells on large 210 mm silicon wafers in a 132-cell configuration. In practical terms, this means significantly more energy can be harvested from the same roof or ground area compared to older PERC-based modules. ### What is TOPCon technology and why is it worth choosing for the GKA210N132 series? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology in which a tunnel oxide passivation layer minimizes charge carrier recombination. In practice, this translates to higher efficiency than conventional PERC cells, improved resistance to light-induced degradation (LID), and more stable energy yield at elevated temperatures. As a result, the GKA210N132 series maintains high performance throughout the entire operational lifetime of the installation. ### Are the Gamko GKA210N132 panels bifacial, and what does that mean for an installation? Yes, the GKA210N132 series consists of bifacial modules. The rear side of the panel captures light reflected from the ground or rooftop surface, generating additional energy — typically 5–15% more depending on the albedo of the underlying surface. To fully exploit this capability, installation at a suitable height above a high-reflectivity surface is recommended, such as light-colored gravel, a white roofing membrane, or sand. Ground-mounted installations with adjustable tilt angle benefit the most from bifacial energy gain. ### What warranty is provided for the Gamko GKA210N132 panels and what does it cover? The manufacturer provides a 12-year product warranty covering material and workmanship defects, as well as a 30-year linear power output warranty. The power warranty guarantees that the panel will retain a minimum performance level as specified in the documentation for the full 30-year period. It is worth noting that any warranty claims are handled directly with the Chinese manufacturer; therefore, purchasing through an authorized distributor with after-sales support in Poland or the EU is strongly recommended. ### Are the 750 W Gamko GKA210N132 panels suitable for building a large-scale photovoltaic farm? Yes, the GKA210N132 750 W series is designed primarily for utility-scale PV farms and industrial installations. The large 210 mm wafers and high power density reduce the total number of modules required to reach the target farm capacity, thereby lowering costs associated with mounting structures, cabling, and labor. The modules are certified for wind loads of 2,400 Pa and snow loads of 5,400 Pa, meeting the structural requirements for ground-mounted installations in the Polish climate. ### How do the Gamko GKA210N132 panels perform under low-irradiance conditions and high temperatures? The N-type TOPCon technology used in the GKA210N132 series features a low temperature coefficient of power, meaning efficiency losses during hot weather are smaller compared to P-type PERC cells. The advanced textured glass and cell surface improve light absorption under overcast conditions, as well as during early morning and late afternoon hours. As a result, the installation generates energy for a longer portion of the day and on less sunny days — a particularly important advantage in the Polish climate. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/gka210n132-730-750w-6d5817162ef7.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | -40 W, cooler, +1.2 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | -45 W, cooler, +1.1 pp | | [AIKO AIKO-A690-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a690-mae78dw) | 690 W | -50 W, cooler, +0.9 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | +50 W, cooler, heavier | | [Trina Solar TSM-NEG21C.20Q-760](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-760) | 760 W | Cooler, heavier, +0.7 pp | | [AIKO AIKO-A785-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a785-grh78dw) | 785 W | +45 W, cooler, heavier | | [Gokin GK-4-78HGBD-780M](https://comparepv.com/panel/gokin-gk-4-78hgbd-780m) | 780 W | +40 W, cooler, heavier | | [AIKO AIKO-A780-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a780-grh78dw) | 780 W | +40 W, cooler, heavier | | [Jetion JT755SLk(B)](https://comparepv.com/panel/jetion-jt755slk-b) | 755 W | Cooler, heavier, +0.5 pp | | [Trina Solar TSM-NEG21C.20Q-755](https://comparepv.com/panel/trina-solar-tsm-neg21c-20q-755) | 755 W | Cooler, heavier, +0.5 pp | | [Gamko New Energy GKA210M132-655W](https://comparepv.com/panel/gamko-new-energy-gka210m132-655w) | 655 W | -85 W, heavier, -2.7 pp | | [Gamko New Energy GKA210M132-660W](https://comparepv.com/panel/gamko-new-energy-gka210m132-660w) | 660 W | -80 W, heavier, -2.6 pp | | [Gamko New Energy GKA210M132-665W](https://comparepv.com/panel/gamko-new-energy-gka210m132-665w) | 665 W | -75 W, heavier, -2.4 pp | | [Gamko New Energy GKA210M132-670W](https://comparepv.com/panel/gamko-new-energy-gka210m132-670w) | 670 W | -70 W, heavier, -2.2 pp | | [Gamko New Energy GKA210M132-675W](https://comparepv.com/panel/gamko-new-energy-gka210m132-675w) | 675 W | -65 W, heavier, -2.1 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +65 W, cooler, heavier | --- Source: https://comparepv.com/panel/gamko-new-energy-gka210n132-740 Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
