On roof space-constrained installations, this translates into measurably higher annual energy yield without increasing the module count. - **N-TOPCon Technology with Bifacial Construction** - N-type cells exhibit a lower LID degradation rate (below 2% in year one vs. ~3% for PERC) and a more favorable temperature coefficient of power. The bifacial design captures an additional 5-25% of energy from reflected irradiance, depending on ground albedo and mounting angle. - **30-Year Power Output Warranty** - The manufacturer offers a linear power output warranty of 30 years - exceeding the 25-year standard common among many manufacturers in this class. The product workmanship warranty is 12 years, which is typical for this market segment. - **Full IEC Certification and Structural Durability** - Modules are certified to IEC 61215 and IEC 61730 (durability and electrical safety) and are rated for mechanical loads of 2,400 Pa wind and 5,400 Pa snow - values consistent with Polish snow load zones II-III and typical wind loads per PN-EN 1991-1-3. - **Anti-PID Protection and Low-Light Performance** - Guaranteed PID resistance limits power degradation in high-voltage systems (typical string voltages of 1,000-1,500 V). Advanced cell and glass surface texturing improves responsiveness under diffuse irradiance - a meaningful advantage in Polish climatic conditions, where average insolation ranges from 1,650 to 1,900 kWh/m²/year. ## Cons - **Not Listed on BNEF Tier 1** - Gamko New Energy does not appear on the official BloombergNEF Tier 1 module manufacturer list (March 2026 methodology). This may present a limitation when seeking financing for commercial installations from banks and project funds that conditionally require modules from BNEF Tier 1-listed manufacturers. Comparable series (HT-SAAE, MY Solar, Weran Solar) are in the same position, making this a segment-wide characteristic rather than an issue specific to this series. - **Heterogeneity Across 18 Variants Within the Series** - The series spans a power range of 580-620 Wp at efficiencies of 22.44%-23.99% - a spread of 1.55 percentage points. When placing an order, it is critical to confirm the exact variant: the entry-level module (580 Wp, ~22.44%) performs significantly worse than the top-tier model (620 Wp, ~23.99%), and overlooking this distinction can result in actual system yield falling short of design estimates. ## About this series The Gamko New Energy GKA182N144 series consists of modules based on **N-TOPCon cells**, designed for high efficiency and stable operation in Polish conditions. The use of a half-cut architecture and **multi-busbar technology** helps to minimize internal losses and improve performance, especially when partial shading from chimneys or skylights occurs on the roof. This is a good choice for investors who want to "extract" more energy from the same area - without compromising durability. The GKA182N144 stands out due to its **PID resistance**, which translates into a significantly lower risk of power degradation over a longer period of operation. Another advantage is **improved performance in low-light conditions** thanks to the refined surface texture of the cells and glass - which is particularly important during the autumn and winter seasons or in cloudy weather. This series is suitable for both premium residential installations and commercial systems on roofs of halls, where efficiency, reliability, and predictable performance are key. ## Notable figures - Efficiency of 23.4% is 0.6pp above the \*\*TOPCon 600-650W\*\* median (22.8%) - 234.1 W/m² power density - 6.4 W/m² more than \*\*TOPCon 600-650W\*\* median (227.7 W/m²), more power per roof area - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 600-650W\*\* median - At 25.0 kg, this panel is 7.8 kg lighter than \*\*TOPCon 600-650W\*\* median (32.8 kg) - easier handling during installation - In the top 6% for efficiency among all TOPCon panels ## Questions ### What is the maximum power output of the Gamko New Energy GKA182N144 panels, and what type of installation are they best suited for? The GKA182N144 series achieves a peak power output of up to 620 Wp, placing it firmly in the high-power module segment. These panels are well suited for premium residential installations where maximizing energy yield from a limited roof area is a priority, as well as for larger commercial systems on industrial rooftops, warehouses, and logistics centers. Thanks to N-TOPCon cell technology, the modules achieve a conversion efficiency of approximately 23-24%. ### What does it mean that the GKA182N144 panel is bifacial, and does it make sense on a Polish rooftop? Bifacial means that the module features an active rear cell surface and can generate electricity from light reflected off the ground or surrounding surfaces, in addition to direct front-side irradiance. In Polish climate conditions, this effect is most pronounced in ground-mounted installations or on highly reflective surfaces - for example, during winter snowfall or against a light-colored facade. On a typical pitched roof, the rear-side energy gain is more modest, but remains a measurable and real contribution throughout the year. ### What warranty is provided for the Gamko New Energy GKA182N144 panels? The manufacturer provides a 12-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. This means that over three decades of operation, the modules must maintain the declared performance levels in accordance with the degradation curve specified in the product datasheet. These warranty terms are standard for N-TOPCon modules in this performance class. ### Do the GKA182N144 panels perform well in winter and under overcast conditions? Yes. The GKA182N144 series employs advanced cell surface texturing and anti-reflective glass treatment, which improves light absorption at low angles of incidence and under diffuse irradiance - conditions typical of Polish autumn and winter. N-TOPCon technology also features a low temperature coefficient, which means these modules operate more efficiently on cold, sunny days compared to older PERC-based modules. ### Is the GKA182N144 series resistant to mechanical damage from snow, wind, and hail? The GKA182N144 series modules carry certified mechanical load ratings of up to 2,400 Pa for wind load and 5,400 Pa for snow load, meeting the requirements for Polish climatic conditions. The dual-tempered glass construction inherent to the bifacial design also provides superior mechanical strength compared to modules with a conventional polymer backsheet. The manufacturer has additionally certified these modules for resistance to salt mist and ammonia exposure. ### How does N-TOPCon technology in the GKA182N144 differ from standard PERC panels, and is the price premium justified? N-TOPCon cells offer higher efficiency and slower long-term degradation than PERC cells. The key differences lie in the substrate type - n-type silicon instead of p-type - and the presence of a tunnel oxide passivation layer, which significantly reduces charge carrier recombination. This translates into better resistance to potential-induced degradation (PID) and a slower power decline over time: the average annual degradation rate for N-TOPCon is approximately 0.4%, compared to roughly 0.55% for PERC. Over a 30-year operational lifespan, this difference results in a meaningfully higher total energy yield, which typically justifies the higher initial cost. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/2025-182n-600w-620w-ad9d1e046982.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +45 W, cooler, +1.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +40 W, cooler, +1.6 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -45 W, cooler, +1.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +35 W, cooler, +1.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -50 W, cooler, +1.2 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +30 W, cooler, +1.2 pp | | [Gamko New Energy GKA182M144-530W](https://comparepv.com/panel/gamko-new-energy-gka182m144-530w) | 530 W | -75 W, hotter, -2.9 pp | | [Gamko New Energy GKA182M144-535W](https://comparepv.com/panel/gamko-new-energy-gka182m144-535w) | 535 W | -70 W, hotter, -2.7 pp | | [Gamko New Energy GKA182M144-540W](https://comparepv.com/panel/gamko-new-energy-gka182m144-540w) | 540 W | -65 W, hotter, -2.5 pp | | [Gamko New Energy GKA182M144-545W](https://comparepv.com/panel/gamko-new-energy-gka182m144-545w) | 545 W | -60 W, hotter, -2.3 pp | | [Gamko New Energy GKA182M144-550W](https://comparepv.com/panel/gamko-new-energy-gka182m144-550w) | 550 W | -55 W, hotter, -2.1 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | Cooler, heavier, +1.0 pp | --- Source: https://comparepv.com/panel/gamko-new-energy-gka182n144s-605w 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.
