Higher power density translates to fewer modules per MW of installed capacity and lower BoS costs. - **Bifacial + Multi-Busbar + Half-Cut** - Bifacial cells enable additional energy yield of 10–20% depending on ground albedo and mounting angle. Multi-busbar technology combined with half-cut cell architecture reduces resistive losses and mitigates the impact of partial shading, which is particularly valuable in commercial rooftop and ground-mounted utility-scale installations. - **Full IEC Certifications and 30-Year Power Warranty** - The series carries IEC 61215, IEC 61730, CE-LVD, CE-EMC, ISO 9001, and ISO 14001 certifications. The manufacturer offers a 30-year linear power warranty — matching Meyer Burger White and exceeding the standard 25-year warranty offered by most Tier-1 suppliers such as JA Solar and Trina Solar. - **Mechanical Resistance: 5400 Pa / 2400 Pa** - Modules are certified for snow loads up to 5400 Pa and wind loads up to 2400 Pa, meeting the requirements for installations in climatic zones with heavy snowfall. These values comply with IEC standards and are essential for industrial installations in demanding northern European environments. - **Salt Mist and Ammonia Resistance** - Certified resistance to salt mist and ammonia enables deployment in harsh industrial environments — including agricultural facilities and coastal sites — without risk of accelerated corrosion of connectors and frames, directly supporting product durability over the 30-year warranty horizon. ## Cons - **No Confirmed BNEF Tier 1 Status** - Gamko New Energy does not appear on publicly available BNEF Tier 1 bankable manufacturer lists (Q1 2026). The absence of this designation may present a barrier to financing large-scale projects (>10 MW) through independent commercial banks and complicate the procurement of project finance in European markets. - **Limited Manufacturer Scale** - Gamko's annual production capacity is approximately 1.2 GW (2023), whereas Tier-1 market leaders — LONGi, JA Solar, and Trina Solar — operate at 50–100 GW per year. The smaller scale may result in higher unit pricing for large orders, limited service availability, and elevated supply continuity risk over the 30-year warranty period. ## About this series The Gamko New Energy GKA210M photovoltaic panel series is based on the use of innovative, large-format silicon cells that redefine the efficiency of modern energy systems. The application of **multi-busbar (MBB)** technology in combination with half-cut cell architecture allows for the effective minimization of resistive losses and a significant improvement in current flow. This solution directly translates into higher module efficiency even on cloudy days or at high operating temperatures. Investors opting for this series primarily gain **lower BOS system costs**, as generating more power from a single module drastically reduces the number of mounting elements and cabling needed. The GKA210M series was designed with demanding commercial installations and solar farms in mind, offering the **lowest levelized cost of energy (LCOE)** in the long-term perspective. It is distinguished from the competition by its **exceptional mechanical resistance** to wind pressure and snow load, confirmed by rigorous quality tests. This is the ideal choice for entities looking for uncompromising energy stability and maximum utilization of available ground or roof space. A special **anti-reflective coating** with low dirt accumulation ensures that the panels maintain high productivity without the need for frequent maintenance. ## Notable figures - Efficiency of 23.0% is 7.0pp above the \*\*TOPCon 0-400W\*\* median (16.0%) - Power density of 207.6 W/m² packs 47.8 W/m² more into the same footprint vs \*\*TOPCon 0-400W\*\* median (159.8 W/m²) - At 17.1 kg, this panel is 6.4 kg lighter than \*\*TOPCon 0-400W\*\* median (23.5 kg) - easier handling during installation - #1919 for efficiency, #13924 for temperature performance out of 14005 panels ## Questions ### Are the Gamko New Energy GKA210M panels bifacial, and what does that mean in practice? Yes, the GKA210M series consists of bifacial modules. The rear surface of the panel captures irradiance reflected from the ground (e.g., light-colored gravel, snow, or a white roofing membrane), generating additional energy. In practice, this translates to a real increase in energy yield of several to over ten percent compared to monofacial panels, particularly in ground-mounted installations with a high-albedo background. ### What power warranty is offered for the Gamko GKA210M panels, and what does it cover? The manufacturer provides a 30-year linear power warranty for the GKA210M series. This means that over three decades of operation, the panel maintains a specified minimum performance level in accordance with a defined degradation schedule. The product warranty covering workmanship and materials is a separate document — it is advisable to ask your distributor for its full scope and terms before purchasing. ### What is the peak power output of the GKA210M panel, and is it sufficient for a residential installation? The peak power of the GKA210M module is 400 Wp. This rating is characteristic of the commercial segment and utility-scale PV farms, where minimizing the levelized cost of energy (LCOE) is the primary driver. For a typical residential system of 5–10 kW, 13–25 modules of this series are sufficient. The high per-unit power output reduces the number of panels and balance-of-system (BoS) mounting components, thereby lowering labor costs. ### Do the Gamko GKA210M panels perform well on overcast days and under low-irradiance conditions? Yes. The half-cut cell technology, combined with an anti-reflective coating and the textured glass surface, improves the absorption of diffuse irradiance under cloudy conditions. The GKA210M series has received certifications confirming high performance at low light intensity, meaning the installation generates energy even on typical Polish overcast days. ### What mechanical loads can the Gamko GKA210M panel withstand — will it hold up in Poland under strong winds and heavy snow? The GKA210M panel is certified for a wind load of up to 2,400 Pa and a snow load of up to 5,400 Pa. Under Polish climatic conditions, these values provide a substantial safety margin above the normative zonal load requirements. The module has also passed salt mist and ammonia resistance tests, confirming its durability in harsh atmospheric environments. ### What is the multi-busbar (MBB) technology used in the GKA210M series, and why does it matter? Multi-busbar technology replaces a small number of wide busbars with a larger number of thin conductors. This shortens the current path within the cell, reducing resistive losses. At the same equivalent cell area, the GKA210M panel therefore produces more energy. Furthermore, the increased number of slender busbars reduces thermally induced mechanical stress within the cell, resulting in a longer service life and lower power degradation over time. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/GKA210M-380-400W-5730c5b36c12.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [JA Solar NS-330MH-80](https://comparepv.com/panel/ja-solar-ns-330mh-80) | 330 W | -50 W, lighter, -5 yr warranty | | [PolyCrown Solar Tech NS-330MH-80](https://comparepv.com/panel/polycrown-solar-tech-ns-330mh-80) | 330 W | -50 W, lighter, -5 yr warranty | | [Gamko New Energy GKA210M340W](https://comparepv.com/panel/gamko-new-energy-gka210m340w) | 340 W | -40 W | | [Gamko New Energy GKA210M360W](https://comparepv.com/panel/gamko-new-energy-gka210m360w) | 360 W | -20 W | | [Gamko New Energy GKA210M380W (1/4\*4\*38)](https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-4-4-38) | 380 W | Very close match | | [Gamko New Energy GKA210M400W (1/2\*4\*20)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-2-4-20) | 400 W | +20 W | | [Gamko New Energy GKA210M400W (1/4\*4\*40)](https://comparepv.com/panel/gamko-new-energy-gka210m400w-1-4-4-40) | 400 W | +20 W | | [Maxeon SPR-MAX3-430-R](https://comparepv.com/panel/maxeon-spr-max3-430-r) | 430 W | +50 W, heavier, +10 yr warranty | | [Maxeon SPR-MAX3-400-COM](https://comparepv.com/panel/maxeon-spr-max3-400-com) | 400 W | +20 W, -0.4 pp, +10 yr warranty | --- Source: https://comparepv.com/panel/gamko-new-energy-gka210m380w-1-2-4-19 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
