This translates into measurably higher annual energy yield under Polish climatic conditions, particularly during summer months when rooftop surface temperatures are elevated. - **Bifacial Design - Additional Yield from Albedo** - The bifacial module construction enables energy harvest from irradiance reflected off the mounting surface. At typical albedo values for light-colored rooftops or ground surfaces (10-25%), bifacial gain reaches 5-15% of additional output, making this feature especially valuable in space-constrained installations. - **30-Year Linear Power Warranty** - The manufacturer offers a 30-year linear power warranty, exceeding the 25-year standard provided by the Suntech Ultra V Pro (the direct competitor in this segment). The extended warranty horizon simplifies IRR calculations and facilitates project financing with banks or lessors that require long-term yield certainty. - **Efficiency Up to 23.04% - Segment-Leading Performance** - The peak efficiency of 23.04% matches the top-performing units in the peer comparison group (SunKean/Sunket SKT430~450M10-108D5: 23.04%) and is significantly higher than the Suntech Ultra V Pro (max. 22.5%). This series therefore delivers the highest available energy yield per square meter among the considered peer comparables. - **Robust Structural Load Ratings (2400/5400 Pa)** - Certified load ratings of 2400 Pa (wind) and 5400 Pa (snow) confirm suitability for operation in the Polish climate (snow load zones up to 3.0 kN/m² per PN-EN 1991-1-3). Anti-reflective coated tempered glass and a high-ingress-protection junction box further support the long-term reliability of outdoor installations. ## Cons - **Not Listed on BNEF Tier 1 (Q1 2026)** - Gamko New Energy does not appear on the BloombergNEF bankable manufacturers list (Q1 2026), which is led by Jinko, LONGi, Trina, JA Solar, Tongwei, and Aiko. The absence of Tier 1 status may present a barrier to project financing (loans, leasing) from financial institutions that routinely require modules sourced from manufacturers on this list. - **Limited Manufacturing Scale vs. Tier 1 Producers** - Gamko's production capacity stood at approximately 1.2 GW/year in 2023, while Tier 1 leaders exceed 80 GW annually. The smaller scale may imply elevated risk regarding spare-part supply continuity and the long-term fulfillment of warranty obligations over a 30-year horizon. ## About this series The Gamko New Energy GKA182N108 series is designed for installations where maximizing energy yield from a limited roof area is crucial. The use of **N-type cells in TOPCon technology** helps maintain high efficiency even in challenging conditions - at elevated temperatures and during periods of reduced sunlight. This is a practical solution to common issues faced by users in Poland: seasonal energy production fluctuations and summer performance drops. A key advantage of this series is **a long linear warranty on power output**, which simplifies long-term investment planning. The modules are also designed for real-world outdoor operation thanks to **a robust construction with tempered glass and anti-reflective coating**, which minimizes light reflection losses. Furthermore, the **high-sealing junction box** ensures reliability in rain, snow, and extreme temperature variations. The GKA182N108 is a good choice for single-family homes, small businesses, and prosumer installations where stable production and predictable performance are expected over the long term. ## Notable figures - Efficiency of 22.5% is 0.5pp above the \*\*TOPCon 400-450W\*\* median (22.0%) - At 225.3 W/m² power density, this panel generates 5.1 W/m² more per unit area than \*\*TOPCon 400-450W\*\* median (220.2 W/m²) - At -0.30%/°C, hot weather performance is typical for \*\*TOPCon 400-450W\*\* panels - Weight of 19.0 kg (3.0 kg below \*\*TOPCon 400-450W\*\* median of 22.0 kg) allows easier transport and roof mounting - In the top 29% for efficiency among all TOPCon panels ## Questions ### What warranty coverage applies to Gamko New Energy GKA182N108 panels? The GKA182N108 series comes with a 12-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. After 30 years of operation, the module is guaranteed to retain at least 87.4% of its nominal rated power. This is one of the longer warranty standards available in this price class, making it easier to evaluate return on investment over multi-decade horizons. ### What does it mean that the GKA182N108 panel is bifacial, and does it matter for a residential rooftop installation? Bifacial means the module can harvest light from both its front side and rear side - for example, irradiance reflected off a lighter-colored roofing surface or underlayment membrane. In a typical pitched-roof installation, the energy gain from the rear side is modest, typically 3-8%, but becomes more pronounced with high-albedo roofing materials or ground-mounted systems. For a standard single-family home this is not a critical parameter, but it does provide an additional efficiency margin at no extra cost. ### How does the GKA182N108 perform during summer high-temperature conditions? N-type TOPCon cells feature a lower power temperature coefficient of -0.30%/°C, which is a better result than standard PERC cells, which typically range from -0.35 to -0.40%/°C. In practice, this means that during hot summer days the GKA182N108 series loses output efficiency more slowly than older PERC-based modules. This advantage is particularly relevant on dark-colored roofs, where module operating temperature can easily exceed 60-70°C. ### How much does a single GKA182N108 panel weigh, and can a typical roof structure support it? The GKA182N108 module weighs approximately 19 kg and measures 1722×1134×30 mm. A typical 10 kWp system comprising around 22 panels results in a combined weight of approximately 420 kg distributed across roughly 43-45 m² of roof area. The vast majority of standard pitched-roof structures in Poland can comfortably support this load; however, if there is any doubt, it is advisable to have a structural engineer assess the roof before installation. ### Are Gamko GKA182N108 panels certified and approved for use in Poland? Yes, the GKA182N108 series holds IEC 61215 and IEC 61730 certifications, both of which are required under European regulatory and safety standards. The modules are tested for mechanical durability, including wind load resistance up to 2,400 Pa and snow load resistance up to 5,400 Pa. They also meet resistance requirements for salt mist and ammonia exposure. Holding these certifications is a mandatory condition for eligibility under Polish subsidy programs such as Mój Prąd. ### What is the maximum power output of the GKA182N108 panel, and how many modules do I need for a 10 kWp system? The highest-power variant in the GKA182N108 series is rated at 450 Wp. To build a system with a total capacity of 10 kWp, you need approximately 22-23 modules. With module efficiency reaching up to 23% and dimensions of 1722×1134 mm, the array will occupy approximately 43-45 m² of roof surface. This is a relatively compact footprint for a system of this capacity, which is a significant advantage for installations on smaller roof sections. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/gka182n108-430-450w-8258d40cafce.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, cooler, +2.0 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, cooler, +2.0 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +45 W, cooler, +1.8 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +45 W, cooler, +1.8 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +45 W, cooler, +1.8 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +45 W, cooler, +1.8 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +45 W, heavier, +1.8 pp | | [Gamko New Energy GKA182M108-395W](https://comparepv.com/panel/gamko-new-energy-gka182m108-395w) | 395 W | -45 W, hotter, -2.3 pp | | [Gamko New Energy GKA182M108-400W](https://comparepv.com/panel/gamko-new-energy-gka182m108-400w) | 400 W | -40 W, hotter, -2.1 pp | | [Gamko New Energy GKA182M108-405W](https://comparepv.com/panel/gamko-new-energy-gka182m108-405w) | 405 W | -35 W, hotter, -1.8 pp | | [Gamko New Energy GKA182M108-410W](https://comparepv.com/panel/gamko-new-energy-gka182m108-410w) | 410 W | -30 W, hotter, -1.5 pp | | [Gamko New Energy GKA182M108-415W](https://comparepv.com/panel/gamko-new-energy-gka182m108-415w) | 415 W | -25 W, hotter, -1.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +70 W, cooler, +2.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +55 W, cooler, +2.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +65 W, cooler, +2.2 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +65 W, heavier, +2.2 pp | --- Source: https://comparepv.com/panel/gamko-new-energy-gka182n108-440 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.
