The ~1.86 percentage-point advantage translates into meaningfully higher energy yield from the same roof or ground area. - **N-Type TOPCon Technology - No LID Effect** - N-type TOPCon cells eliminate light-induced degradation (LID), which in legacy PERC modules can cause up to 2-3% power loss during the first months of operation. The lower temperature coefficient inherent to this technology also ensures higher power output on hot days, which is particularly relevant during summer generation peaks in Poland. - **Bifacial Design - Additional Yield from the Rear Side** - The bifacial construction enables absorption of irradiance reflected from the ground surface. In ground-mounted installations with a light-colored substrate or snow cover, this can increase annual energy yield by 5-15% compared to a monofacial module of equivalent STC power rating. - **30-Year Power Output Warranty** - The manufacturer provides a 30-year performance warranty, exceeding the 25-year standard offered by most peers in this price class (Goldi Solar, S-Energy). For commercial installations with longer financing horizons, this represents a significant advantage in LCOE analysis. - **High Mechanical Load Ratings: 5400 Pa Snow / 2400 Pa Wind** - Certified mechanical load ratings per IEC 61215 (5400 Pa snow, 2400 Pa wind) make this series well suited for Polish climatic conditions, including mountainous regions with heavy snowfall, without requiring additional structural reinforcements. ## Cons - **No Tier 1 Status on BNEF / Wood Mackenzie Lists** - Gamko New Energy (annual production capacity ~1.2 GW as of 2023 data) does not appear on the BloombergNEF Tier 1 or Wood Mackenzie H1 2025/Q1 2026 module lists, which serve as the reference standard for institutions financing utility-scale PV projects. This may complicate or preclude bank financing for larger commercial installations that require a bankable equipment list. ## About this series The Gamko GKA182N132 photovoltaic panel series utilizes innovative **N-type TOPCon cell technology**, placing it at the forefront of solutions in terms of efficiency and durability. The use of large 182 mm silicon wafers combined with a half-cut design significantly reduces resistance losses, which translates into stable module operation even in difficult lighting conditions typical for the Polish climate. A key advantage of this series is its **exceptionally low temperature coefficient**, thanks to which the panels maintain high efficiency on hot days when traditional modules lose power. The use of N-type cells effectively eliminates the problem of light-induced degradation (LID), guaranteeing investors a **longer lifespan and higher energy yields** over decades of operation. This solution is dedicated primarily to large commercial installations and demanding prosumers looking for an optimal balance between modern technology and a fast return on investment. The solid frame construction ensures **high resistance to mechanical loads**, such as heavy snow or strong wind, making the GKA182N132 series a safe choice for rooftop and ground-mounted farms. Thanks to precise quality control, these panels offer consistent parameters, which sets them apart from standard products available on the market. ## Notable figures - At 23.2% efficiency, this panel is 0.7pp above typical \*\*TOPCon 550-600W\*\* modules (median: 22.4%) - Power density of 231.6 W/m² packs 7.2 W/m² more into the same footprint vs \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - Temperature coefficient of -0.30%/°C matches the \*\*TOPCon 550-600W\*\* median - Weight of 23.0 kg (8.2 kg below \*\*TOPCon 550-600W\*\* median of 31.2 kg) allows easier transport and roof mounting - Ranked #1533 out of 14129 panels for efficiency in the database ## Questions ### What warranty does the Gamko GKA182N132 series carry and what does it cover? The GKA182N132 series comes with a 12-year product warranty covering material and workmanship defects, along with a 30-year power output warranty. The manufacturer guarantees that after 30 years of operation the module will retain at least 87.4% of its nominal power. N-type TOPCon cell technology effectively eliminates LID degradation, so real-world energy yields remain more stable throughout the entire warranty period compared to legacy P-type cells. ### What does it mean that the Gamko GKA182N132 is bifacial, and does it make sense for a rooftop installation? A bifacial module harvests light through both its front and rear cell surfaces. On a pitched roof the rear-side gain is limited and depends on the albedo of the underlying surface, but in ground-mounted systems or over high-reflectivity substrates it can contribute an additional 5-15% of energy yield. For rooftop installations, the primary benefit of bifaciality in this module lies in the inherently higher cell efficiency of N-type TOPCon technology, which reaches 23.16% for this module. ### Can the Gamko GKA182N132 550 W modules handle heavy snow loads typical in Poland? Yes. The GKA182N132 module is certified for a snow load of 5,400 Pa and a wind load of 2,400 Pa. Polish standards for snow loads typically range from 1,000 to 2,000 Pa depending on the climatic zone, so the module exceeds those requirements with a substantial safety margin. The anodized aluminum frame and 3.2 mm tempered glass ensure structural integrity throughout the entire service life. ### Does TOPCon technology in the GKA182N132 series genuinely deliver better performance on overcast days? Yes. N-type TOPCon cells exhibit higher sensitivity to diffuse irradiance than conventional PERC cells. In typical Polish conditions-characterized by frequent cloud cover-this means the module generates proportionally more energy than older technologies of comparable nominal power. In addition, the exceptionally low temperature coefficient ensures that on hot days the GKA182N132 suffers less power loss than P-type modules. ### What types of installations is the Gamko GKA182N132 550 Wp series best suited for? The GKA182N132 550 Wp series is primarily designed for large commercial installations, utility-scale ground-mounted solar farms, and industrial applications where a high per-module power rating reduces BoS costs, including mounting hardware and cabling. The module's physical dimensions (2,094 × 1,134 mm) require appropriately engineered racking structures. Demanding prosumers with large roof surfaces or land available can also deploy this series successfully, achieving a faster return on investment. ### How does the Gamko GKA182N132 differ from this manufacturer's older M-type (PERC) models? The fundamental difference is cell technology: the GKA182N132 uses N-type TOPCon cells, whereas older Gamko series (e.g., GKA182M132) are based on P-type PERC cells. N-type cells offer higher efficiency (up to 23.16% vs. approximately 21% for PERC), zero LID degradation, and a superior temperature coefficient. This translates into higher annual energy yields and greater long-term power stability over a 30-year operating lifetime. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/gka182n132-530-550w-da9e00df08b2.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | -40 W, cooler, +1.8 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, heavier, +1.6 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | -45 W, cooler, +1.5 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | -45 W, cooler, +1.5 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, heavier, +1.4 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | -50 W, cooler, +1.3 pp | | [Gamko New Energy GKA182M132S-485](https://comparepv.com/panel/gamko-new-energy-gka182m132s-485) | 485 W | -65 W, hotter, -2.7 pp | | [Gamko New Energy GKA182M132S-490](https://comparepv.com/panel/gamko-new-energy-gka182m132s-490) | 490 W | -60 W, hotter, -2.5 pp | | [Gamko New Energy GKA182M132S-495](https://comparepv.com/panel/gamko-new-energy-gka182m132s-495) | 495 W | -55 W, hotter, -2.3 pp | | [Gamko New Energy GKA182M132S-500](https://comparepv.com/panel/gamko-new-energy-gka182m132s-500) | 500 W | -50 W, hotter, -2.1 pp | | [Gamko New Energy GKA182M132S-505](https://comparepv.com/panel/gamko-new-energy-gka182m132s-505) | 505 W | -45 W, hotter, -1.9 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +40 W, heavier, +0.7 pp | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +35 W, heavier, +0.5 pp | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +30 W, heavier, +0.3 pp | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +30 W, heavier, +0.3 pp | --- Source: https://comparepv.com/panel/gamko-new-energy-gka182n132-550w 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.
