The series therefore ranks at the very top of large-format 700–720 W modules available on the market in 2025–2026. - **N-type TOPCon technology — low degradation** - N-type TOPCon cells are free from boron-oxygen-induced LID and exhibit no LeTID, with an annual degradation rate of ≤0.40%/year compared to 0.45–0.55%/year for PERC modules. Over a 30-year project lifetime, this translates into measurably higher cumulative energy yield from the same installed area. - **30-year linear power warranty** - Gamko provides a linear power output warranty for 30 years, with first-year degradation ≤1% and ≤0.4% per year thereafter. The market standard for PERC modules is 25 years; the extended warranty directly lengthens the horizon of guaranteed revenue for PPA projects. - **Bifacial variant with up to 85% bifaciality** - The GKA210N132BF glass-glass configuration enables an additional 5–15% energy gain from reflected irradiance (albedo) in typical ground-mount installations and carports over light-colored surfaces. A bifaciality factor of 85% is on par with the best bifacial TOPCon modules in this power class. - **Structural load ratings suited to Polish conditions** - Certified load ratings of 2,400 Pa (wind) and 5,400 Pa (snow) satisfy the requirements for the vast majority of locations in Poland in accordance with EN 1991-1-3, simplifying engineering procedures for both rooftop and ground-mount installations. ## Cons - **No BNEF Tier 1 status** - Gamko New Energy does not appear on the BNEF Tier 1 list (Q1 2026 or any prior edition), meaning its bankability has not been independently confirmed — a requirement imposed by most commercial lenders for PV project financing above 10 MW. Projects requiring project finance may need additional due diligence or module warranty insurance. - **Limited manufacturing scale** - Gamko's annual production capacity was approximately 1.2 GW in 2023, while leading Tier 1 manufacturers (JA Solar ~80 GW, Trina Solar ~50 GW) operate at many times that capacity. For large orders (>5 MWp), this may introduce supply-chain timing risk and reduce pricing stability under long-term procurement contracts. ## About this series The Gamko New Energy GKA210N132 series consists of large-format modules based on N-type monocrystalline cells using the **TOPCon** technology, designed to maximize energy yield for a given surface area. In practice, they stand out due to their **high efficiency** and stable operation in demanding conditions - which is particularly important in Poland, with its variable weather and frequent periods of reduced solar irradiance. The manufacturer also emphasizes **PID resistance**, which helps to reduce the risk of accelerated degradation in installations operating at higher voltages. The GKA210N132S Standard version is a versatile choice for PV farms and commercial installations. The GKA210N132BK Black version is ideal for applications where aesthetics are important, such as representative roofs of service buildings. The GKA210N132BF Bifacial, with its **bifacial design** and commonly used glass-on-glass system, allows for better utilization of reflected light, which is particularly beneficial in bright environments, in ground-mounted and carport systems. This series is for investors who expect real benefits in terms of yield, durability, and the flexibility to choose the version that best suits their project. ## Notable figures - Efficiency of 23.0% matches the \*\*TOPCon 700-750W\*\* median - At 230.2 W/m² power density, roof space requirements are typical for \*\*TOPCon 700-750W\*\* panels - At -0.34%/°C, loses 0.05pp more power per degree than \*\*TOPCon 700-750W\*\* median (-0.29%/°C) - Weight of 32.0 kg (6.0 kg below \*\*TOPCon 700-750W\*\* median of 38.0 kg) allows easier transport and roof mounting - In the top 13% for efficiency among all TOPCon panels ## Questions ### What warranty is offered on the Gamko New Energy GKA210N132 panels? The manufacturer provides a 12-year product warranty on GKA210N132 series modules and a 30-year linear power output warranty. This means that over three decades the panel is guaranteed to maintain a defined efficiency level in accordance with the degradation curve specified in the datasheet. These are standard warranty terms for premium-class TOPCon modules and are comparable to those offered by leading manufacturers in the industry. ### What is TOPCon technology and why does the GKA210N132 series use it? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that achieves higher conversion efficiency than older PERC cells. In the GKA210N132 series, this translates to a module efficiency of up to 23.18%, which means more energy generated from the same roof area. N-type cells are also less susceptible to LID (Light Induced Degradation), so the panel experiences less power loss during its initial hours of operation. ### How does the GKA210N132BF Bifacial variant differ from the standard GKA210N132S? The Bifacial variant features a dual-glass, double-sided construction that captures light from both the front and the rear of the module, utilizing irradiance reflected from the mounting surface below. On highly reflective surfaces — such as in ground-mounted, agrivoltaic, or carport installations — energy yield can be several to more than ten percent higher than that of a standard single-sided panel. The GKA210N132S is the classic choice for pitched rooftops and commercial installations where the bifacial gain cannot be effectively utilized. ### Do Gamko GKA210N132 panels perform well in Poland's climate with frequent cloud cover and low irradiance? Yes. The GKA210N132 series is equipped with N-TOPCon cells featuring textured glass and optimized optics that improve the absorption of diffuse light. The manufacturer certifies these modules as low-light performance rated, which is particularly important in Poland, where overcast days and a low solar angle in winter are the norm. PID (Potential Induced Degradation) resistance further protects against accelerated power loss in systems operating at higher system voltages. ### What mechanical loads can the Gamko GKA210N132 modules withstand — are they suitable for regions with heavy snowfall? GKA210N132 series modules are certified to withstand a snow load of 5,400 Pa and a wind load of 2,400 Pa. For reference, 5,400 Pa corresponds to a layer of wet snow approximately 50–60 cm deep. In practice, this means the panels are well suited for mountainous regions of Poland and rooftops exposed to heavy precipitation, provided the mounting structure is properly engineered and installed. ### Is the GKA210N132BK Black variant suitable for the roof of an office or commercial building? Yes. The Black variant was developed specifically for installations where aesthetics matter. The black frame and dark backsheet deliver a uniform, understated appearance on the representative rooftops of commercial buildings, office complexes, and apartment developments. Technical specifications and warranties are identical to those of the Standard version, with a marginally higher purchase cost for the visual effect. It is a popular choice for installations visible from street level or required by an architectural design brief. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/gka210n132-700-720w-b794471e0e1f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | -35 W, cooler, +2.2 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | -40 W, cooler, +2.0 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, heavier, +2.0 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, heavier, +1.9 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | -45 W, cooler, +1.8 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | -45 W, cooler, +1.8 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | -45 W, cooler, +1.8 pp | | [Gamko New Energy GKA210M132-655W](https://comparepv.com/panel/gamko-new-energy-gka210m132-655w) | 655 W | -60 W, heavier, -1.9 pp | | [Gamko New Energy GKA210M132-660W](https://comparepv.com/panel/gamko-new-energy-gka210m132-660w) | 660 W | -55 W, heavier, -1.8 pp | | [Gamko New Energy GKA210M132-665W](https://comparepv.com/panel/gamko-new-energy-gka210m132-665w) | 665 W | -50 W, heavier, -1.6 pp | | [Gamko New Energy GKA210M132-670W](https://comparepv.com/panel/gamko-new-energy-gka210m132-670w) | 670 W | -45 W, heavier, -1.4 pp | | [Gamko New Energy GKA210M132-675W](https://comparepv.com/panel/gamko-new-energy-gka210m132-675w) | 675 W | -40 W, heavier, -1.3 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +90 W, cooler, +2.1 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +85 W, cooler, +1.9 pp | | [AIKO AIKO-A795-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a795-grh78dw) | 795 W | +80 W, cooler, +1.8 pp | | [AIKO AIKO-A790-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a790-grh78dw) | 790 W | Cooler, heavier, +1.6 pp | --- Source: https://comparepv.com/panel/gamko-new-energy-gka210n132-715w-series Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
