This difference translates into measurably higher energy yield per m² of roof area for any given installation footprint. - **Low temperature coefficient with N-type TOPCon technology** - The Pmax temperature coefficient is -0.34%/°C, which at a module operating temperature of 65°C (+40°C above STC) results in approximately 1.6 percentage points fewer losses than a typical PERC module (-0.38%/°C). The elimination of LID inherent to N-type cells further limits degradation during the initial years of operation. - **Bifacial + half-cut, 108 cells on 210 mm wafer** - The bifacial design enables an additional energy yield of 5–25% from reflected irradiance, depending on ground albedo (e.g., white gravel ~50%, concrete ~25%). Half-cut cells reduce resistive losses and improve resilience to partial shading compared to full-cell modules. - **Commercial-grade mechanical durability** - Certified load resistance of 2,400 Pa (wind) and 5,400 Pa (snow), combined with verified resistance to salt mist and ammonia, makes this series suitable for demanding locations — including coastal, agricultural, and industrial rooftop sites — without additional installation restrictions. - **30-year linear power output warranty** - The manufacturer guarantees 84.8% of nominal power output after 30 years of operation. A 30-year warranty horizon is uncommon among smaller manufacturers — most offer 25 years — providing a longer, predictable degradation model and reducing investment risk in projects with extended payback periods. ## Cons - **Product warranty limited to 12 years** - Leading TOPCon manufacturers (Jinko Tiger NEO, Trina Vertex S+, JA Solar Deep Blue 4.0 Pro) standardly offer 15–25 years of product warranty against manufacturing defects. The Gamko GKA210N108's 12-year product warranty falls short by a minimum of 3 years, which is a significant consideration for bank-financed installations or projects with planned service periods exceeding 12 years. - **Manufacturer not on BNEF Tier 1 list (Q1 2026)** - Nantong Gamko New Energy (capacity ~1.2 GW/year) does not appear on the BloombergNEF Tier 1 list for Q1 2026, which is dominated by LONGi, Jinko, Trina, and JA Solar (each at 80+ GW/year). The absence of Tier 1 status may complicate securing project financing above 1 MW and could limit spare-parts availability over a >15-year horizon. - **Power warranty of 84.8% after 30 years — below premium tier** - The stated retention of 84.8% output power after 30 years corresponds to an annual degradation rate of ~0.50%/year — higher than that offered by Jinko Tiger NEO (≥87.4%, ~0.40%/year) or JA Solar Deep Blue 4.0 Pro (≥87.4%). On a 10 kWp system, this cumulative difference over 30 years represents approximately 500–700 kWh less total energy generated. ## About this series The **Gamko New Energy GKA210N108** series redefines efficiency standards in the residential and commercial rooftop installation segment, based on advanced **N-type TOPCon** cell technology. The use of 210 mm silicon wafers combined with a 108 half-cut cell design allows for exceptionally high power density while maintaining compact module dimensions. This solves the problem of limited installation space, offering investors maximum energy yield from every square meter of the roof. A key advantage of this series is the near-total **elimination of the LID degradation effect** and a significantly lower temperature coefficient, which translates into stable operation and higher electricity production on hot days and in low sunlight. Choosing this product line is an investment in long-term reliability, as N-type cells show a much slower decline in efficiency over time than traditional P-type solutions. **Excellent low-current characteristics** make these panels work perfectly with modern inverters, minimizing transmission losses. This solution is dedicated to demanding users who seek uncompromising quality and want to shorten their return on investment thanks to **above-average performance in real-world weather conditions**, which clearly distinguishes this series from standard products available on the market. ## Notable figures - At 22.7% efficiency, this panel is on par with typical \*\*TOPCon 550-600W\*\* modules - Power density of 227.1 W/m² matches the \*\*TOPCon 550-600W\*\* median - Temperature coefficient of -0.34%/°C is 0.05pp worse than \*\*TOPCon 550-600W\*\* median (-0.29%/°C) - higher losses in summer heat - 25.5 kg weight - 5.7 kg lighter than \*\*TOPCon 550-600W\*\* median (31.2 kg), reducing installation effort - Ranked #3285 out of 14005 panels for efficiency in the database ## Questions ### What warranty does the Gamko New Energy GKA210N108 series carry, and what exactly does it cover? The GKA210N108 series comes with a 12-year product warranty covering material defects and workmanship, as well as a 30-year linear power output warranty. The latter means the manufacturer guarantees that the module will maintain its power output above a specified level for three decades. In practice, N-type TOPCon cells degrade more slowly than conventional P-type cells, so the actual service life frequently exceeds the warranted performance parameters. ### Is the Gamko New Energy GKA210N108 a bifacial panel, and how much additional energy does bifaciality provide? Yes, the GKA210N108 is a bifacial module that captures irradiance from both the front side and the rear side — for example, light reflected from roofing material, gravel, or snow. Depending on the albedo of the surface below and the mounting angle, rear-side generation typically contributes an additional 10–20% of energy relative to the nameplate power rating. This bifacial gain is most pronounced over high-albedo, reflective surfaces and in ground-mounted installations, but it also delivers measurable benefits on light-colored metal roofs. ### How does the 580 Wp GKA210N108 panel perform during summer when ambient temperatures exceed 35°C? The N-type TOPCon technology used in the GKA210N108 series has a lower temperature coefficient than standard P-type cells. This means that power output degrades less steeply as module temperature rises above 25°C (STC). On hot days, power losses are measurably lower, and real-world energy production is noticeably higher compared to previous-generation panels with the same nominal rating of 580 Wp. ### Is the GKA210N108 series suitable for installation on a typical pitched roof of a single-family home? Yes, the GKA210N108 series is built around 210 mm wafers in a 108 half-cut cell configuration, which delivers high power density within relatively compact module dimensions. This makes installation easier on roofs with limited usable surface area. The module is certified for wind loads up to 2,400 Pa and snow loads up to 5,400 Pa, meeting the requirements of typical residential rooftop installations in Poland. Mechanical durability is therefore not a limiting factor for standard roofing structures. ### How do the N-type TOPCon cells in the GKA210N108 series differ from mainstream P-type panels, and is the price premium justified? N-type TOPCon cells virtually eliminate the LID (Light Induced Degradation) effect, which causes P-type modules to lose as much as 2–3% of their rated power shortly after installation. In addition, they offer higher conversion efficiency — the GKA210N108 reaches up to 22.44% — and superior performance under low-irradiance conditions and at elevated temperatures. This translates into meaningfully higher annual energy yield and a shorter investment payback period, which justifies the higher purchase price. ### Which inverters are compatible with the 580 Wp Gamko New Energy GKA210N108 panels? The GKA210N108 modules at 580 Wp produce a relatively high open-circuit voltage, characteristic of a 108-cell configuration. They are compatible with grid-tie inverters from leading manufacturers such as SMA, Fronius, Huawei, and Growatt, provided that the inverter's MPPT input voltage range encompasses the string voltage parameters of arrays built from these modules. Before purchasing, it is advisable to review the string design with a qualified installer or to use the inverter manufacturer's string sizing calculator. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/GKA210N108-560-580W-9c50f302e7c1.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -20 W, cooler, +2.1 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -25 W, cooler, +1.9 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | Cooler, heavier, +1.7 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +1.7 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -40 W, cooler, +1.7 pp | | [Gamko New Energy GKA210M108-530W](https://comparepv.com/panel/gamko-new-energy-gka210m108-530w) | 530 W | -50 W, -2.0 pp | | [Gamko New Energy GKA210M108-535W](https://comparepv.com/panel/gamko-new-energy-gka210m108-535w) | 535 W | -45 W, -1.8 pp | | [Gamko New Energy GKA210M108-540W](https://comparepv.com/panel/gamko-new-energy-gka210m108-540w) | 540 W | -40 W, -1.6 pp | | [Gamko New Energy GKA210M108-545W](https://comparepv.com/panel/gamko-new-energy-gka210m108-545w) | 545 W | -35 W, -1.4 pp | | [Gamko New Energy GKA210M108-550W](https://comparepv.com/panel/gamko-new-energy-gka210m108-550w) | 550 W | -30 W, -1.2 pp | | [Jetion JT590SJk(B)](https://comparepv.com/panel/jetion-jt590sjk-b) | 590 W | Cooler, heavier, +0.4 pp | | [Resun Solar RS9V-M-DG-590](https://comparepv.com/panel/resun-solar-rs9v-m-dg-590) | 590 W | Cooler, heavier, +0.4 pp | | [Jetion JT585SJk(B)](https://comparepv.com/panel/jetion-jt585sjk-b) | 585 W | Cooler, heavier | | [Resun Solar RS9V-M-DG-585](https://comparepv.com/panel/resun-solar-rs9v-m-dg-585) | 585 W | Cooler, heavier | | [Jetion JT580SJk(B)](https://comparepv.com/panel/jetion-jt580sjk-b) | 580 W | Cooler, heavier | | [Resun Solar RS9V-M-DG-580](https://comparepv.com/panel/resun-solar-rs9v-m-dg-580) | 580 W | Cooler, heavier | --- Source: https://comparepv.com/panel/gamko-new-energy-gka210n108-580w 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.
