The multi-busbar (MBB) architecture shortens current pathways and reduces resistive losses, resulting in higher annual energy yield-particularly during shoulder months and under diffuse irradiance conditions. - **Bifacial Dual-Glass Construction** - The module harvests energy from both front and rear surfaces; with high-albedo ground cover (concrete, sand, or snow) or ground-mounted installations with appropriate albedo, an additional 5-15% energy gain over monofacial modules is achievable for the same roof or land footprint. - **Module Efficiency of 22.16-23.1%, Outperforming 2 of 3 Peers** - Emmvee GRAPHITE Monoperc (21.03%) and Lina Energy LEPV 132 HC (21.06%) trail by 1.1-2.1 percentage points. For a 50 m² installation, this difference translates to a real gain of 550-1,050 Wp of installed capacity without increasing the module count. - **30-Year Linear Power Warranty** - The manufacturer guarantees a linear degradation profile over 30 years-5 years beyond the market standard for legacy PERC modules (25 years). This provides investors with more predictable energy production and simplifies financial modeling for both residential prosumer and commercial installations. - **Full Certification Suite and High Mechanical Load Ratings** - The series carries IEC 61215, IEC 61730, ISO 9001, ISO 14001, CE, and RoHS certifications, along with rated mechanical load resistance of 2,400 Pa (wind) and 5,400 Pa (snow), as well as salt mist and ammonia corrosion certifications-making it suitable for industrial and coastal deployment sites. ## Cons - **Efficiency Below Segment Leader** - The Gokin GK-3-54HGF achieves 24.5% efficiency at the same 500 Wp maximum power output, representing a 1.4-2.3 percentage point advantage over the best-performing GKA182N120 variant (23.1%). For space-constrained installations, this gap has a tangible impact on peak power calculations. - **No BNEF Tier-1 Status** - Gamko New Energy (manufacturing capacity of 1.2 GW/year as of 2023) does not appear on the published Bloomberg NEF Tier-1 module manufacturer lists for Q1 2026. For commercial projects requiring debt financing or insurance from underwriters that mandate a Tier-1 guarantor, this may represent a genuine barrier to entry. - **Product Warranty Limited to 12 Years** - A 12-year product warranty sits at the lower bound of the market standard for TOPCon-class modules: Hyundai offers 25 years and SolarSpace offers 15 years, both with the same 30-year linear power warranty. Any mechanical defect or physical damage occurring after year 12 becomes the system owner's financial responsibility. ## About this series The Gamko New Energy GKA182N120 series consists of modules based on **N-type cells in TOPCon technology**, designed to maximize energy generation from the same roof or ground area. The use of a **multi-shed MBB architecture** improves power generation and reduces losses, resulting in more stable operation even with partial shading and in weaker light conditions. The **high PID resistance** is also noteworthy - a key factor where long-term predictable production and reduced degradation are important. In practice, these panels perform well in both residential and commercial installations, especially when the investor wants to maximize power output in a limited space or improve performance during transitional months. The series also features **resistance to harsh environmental conditions**, which will be appreciated by users in locations exposed to wind, snow, or industrial environments. Thanks to **long linear power warranties**, this is a choice for those seeking real durability, not just paper specifications. ## Notable figures - Efficiency of 22.9% matches the \*\*TOPCon 450-500W\*\* median - At 228.7 W/m² power density, this panel generates 3.5 W/m² more per unit area than \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 450-500W\*\* median - At 21.0 kg, this panel is 3.0 kg lighter than \*\*TOPCon 450-500W\*\* median (24.0 kg) - easier handling during installation - Ranked #2585 out of 14129 panels for efficiency in the database ## Questions ### What is the warranty on the Gamko New Energy GKA182N120 panels? The GKA182N120 series comes with a 12-year product warranty covering manufacturing defects and workmanship, as well as a 30-year linear power output warranty. The linear power warranty guarantees that over three decades the panel will retain a specified minimum percentage of its nominal power rating, enabling precise long-term energy yield forecasting and return-on-investment calculations throughout the entire operational lifetime of the system. ### What is TOPCon technology and why should I choose it in the GKA182N120 series? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that incorporates an ultra-thin tunnel oxide layer to suppress charge-carrier recombination at the rear contact. In practice, this translates into higher module efficiency (up to 23.18%) compared to conventional PERC cells, superior low-light performance, and greater resistance to PID (Potential-Induced Degradation). The GKA182N120 series leverages these advantages to deliver a higher annual energy yield from the same roof area. ### Is the GKA182N120 panel bifacial, and what does that mean for my installation? Yes, the GKA182N120 is a bifacial module, meaning it captures solar irradiance from both its front and rear surfaces. The rear side harvests albedo - reflected light from the ground surface beneath the array - which can increase total energy yield by several to over ten percent, depending on the reflectivity of the substrate (e.g., light-colored gravel ballast, white roofing membrane, or snow cover). The bifacial gain is most pronounced in ground-mounted systems and flat-roof installations equipped with a suitably reflective surface. ### Can the Gamko GKA182N120 panels withstand harsh weather conditions such as strong wind and heavy snow loads? Yes, the GKA182N120 series is certified to withstand wind loads of 2,400 Pa and snow loads of 5,400 Pa. Both values exceed the typical structural requirements for residential rooftops in Poland, meaning the panels are suitable even for alpine locations or industrial sites exposed to heavy snowfall and high-velocity wind gusts. Additional certifications for salt mist and ammonia resistance further confirm the modules' durability in demanding environmental conditions. ### What is the maximum power output of the GKA182N120 panel, and how many modules do I need for a residential installation? The GKA182N120 module has a maximum power rating of 500 Wp. A typical residential system sized at 6 kWp requires only 12 panels from this series, while a 10 kWp system requires 20 modules. The high per-module power rating means fewer panels are needed on the roof, simplifying installation logistics and allowing a greater total system capacity to be fitted within a limited roof or ground area. ### Does the GKA182N120 series perform well in winter and on overcast days? Yes, the N-type TOPCon cells used in the GKA182N120 series exhibit superior low-irradiance performance compared to standard PERC cells. The multi-busbar (MBB) cell architecture further reduces power losses caused by partial shading. In practice, this results in higher energy yields during transitional months (March-April and September-October) and under the overcast sky conditions characteristic of the Polish climate. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/gka182n120-480-500w-7c5e4a32569c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, heavier, +2.1 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, +1.9 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, heavier, +1.8 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | Cooler, heavier, +1.8 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, +1.6 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, heavier, +1.6 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | Cooler, +1.6 pp | | [Gamko New Energy GKA182M120 440W](https://comparepv.com/panel/gamko-new-energy-gka182m120-440w) | 440 W | -55 W, hotter, -2.6 pp | | [Gamko New Energy GKA182M120 445W](https://comparepv.com/panel/gamko-new-energy-gka182m120-445w) | 445 W | -50 W, hotter, -2.3 pp | | [Gamko New Energy GKA182M120 450W](https://comparepv.com/panel/gamko-new-energy-gka182m120-450w) | 450 W | -45 W, hotter, -2.1 pp | | [Gamko New Energy GKA182M120 455W](https://comparepv.com/panel/gamko-new-energy-gka182m120-455w) | 455 W | -40 W, hotter, -1.9 pp | | [Gamko New Energy GKA182M120 460W](https://comparepv.com/panel/gamko-new-energy-gka182m120-460w) | 460 W | -35 W, hotter, -1.6 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +65 W, heavier, +1.9 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +60 W, heavier, +1.7 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +55 W, lighter, +1.5 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +45 W, cooler, +1.5 pp | --- Source: https://comparepv.com/panel/gamko-new-energy-gka182n120-495 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.
