The ~1.9 percentage point advantage translates into a meaningfully smaller required installation area or higher energy yield on the same roof surface. - **N-TOPCon Technology with Bifacial Design** - Bifacial N-TOPCon cells exhibit lower LID/LeTID degradation rates and a better power temperature coefficient than legacy PERC cells (typically -0.29%/°C vs. -0.35%/°C for PERC). In the Polish climate - characterized by a high proportion of sunny summer days and reflected irradiance in winter - this delivers a measurably higher annual energy yield. - **30-Year Linear Power Warranty** - The manufacturer guarantees power output for 30 years, exceeding the 25-year standard offered by the IBC Solar 182M reference series and by Goldi Solar and S-Energy models. The extended warranty horizon reduces financial risk for installations with long payback periods (12-15 years for residential prosumers). - **High Mechanical Load Resistance** - The module is certified for wind loads of 2,400 Pa and snow loads of 5,400 Pa (per ENF Solar datasheet), meeting Polish building code requirements even in high-snowfall zones. The IP68-rated junction box ensures watertight integrity under prolonged water immersion. - **PID Resistance and IEC Certifications** - The series carries certified resistance to Potential Induced Degradation (PID) along with IEC 61215 and IEC 61730 certifications - baseline requirements for installations financed through EU funds and for contracts with insurers operating in Poland. ## Cons - **12-Year Product Warranty Falls Short of Industry Standard** - The product warranty stands at 12 years, whereas leading premium-segment manufacturers (JA Solar, LONGi, Jinko Solar) routinely offer 15 years. For commercial installations governed by service-level agreements, this gap may constitute a formal disqualifying criterion in competitive tender processes. - **Not Listed as Tier-1 by Bloomberg BNEF** - Gamko New Energy (Nantong, China; ~1.2 GW of manufacturing capacity in 2023) does not appear on the Bloomberg BNEF Tier-1 Module Manufacturers list, which constrains project bankability - a number of banks and infrastructure funds require Tier-1 status as a financing prerequisite for systems exceeding 50 kWp. ## About this series The Gamko New Energy GKA182N132 (530W-550W) series is designed to maximize energy yield on the same roof or ground area, without compromising durability. The use of **N-TOPCon** cells allows for better performance at high temperatures and reduces degradation over time, resulting in more stable production over multiple seasons. The **M-busbar** design supports efficient current collection from the cells and helps reduce losses, while also improving the aesthetic appearance of the modules on rooftop installations. In practice, this series solves a common problem for investors: how to extract the maximum from limited space and achieve more reliable performance in less sunny conditions. The modules are designed for real-world operating conditions thanks to **PID resistance**, a robust enclosure with an **IP68 junction box**, and a design optimized for long-term, trouble-free operation. This is a good choice for residential, commercial, and agricultural installations, where predictable yield and weather resistance are important. ## Notable figures - 23.2% module efficiency - 0.7pp better than the \*\*TOPCon 550-600W\*\* median of 22.4% - 231.6 W/m² power density - 7.2 W/m² more than \*\*TOPCon 550-600W\*\* median (224.4 W/m²), more power per roof area - 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 Gamko New Energy offer on the GKA182N132 series? The manufacturer provides a 12-year product warranty on GKA182N132 modules, covering material and workmanship defects. In addition, a 30-year linear power output warranty is included, guaranteeing that the panel will not degrade beyond defined threshold limits over the system's lifetime. This represents the standard warranty level for premium-class modules built on N-TOPCon technology. ### What is N-TOPCon technology and why is it worth choosing in the GKA182N132 series? N-TOPCon is a next-generation monocrystalline cell architecture in which a thin silicon oxide passivation layer suppresses carrier recombination at the cell surface. In practice, this translates to higher conversion efficiency - exceeding 23% in the GKA182N132 series - better performance at elevated temperatures, and a lower annual degradation rate compared to mainstream PERC cells. For the end investor, this means more energy harvested from the same roof area over the entire service life of the system. ### Are the Gamko GKA182N132 panels bifacial, and how much additional energy can be gained? Yes, the GKA182N132 series is manufactured in bifacial technology - the rear glass surface also captures irradiance reflected from the ground or rooftop substrate. Depending on the albedo coefficient of the surface (light-colored concrete, gravel, white membrane, etc.), the real-world bifacial gain typically ranges from 5% to 15% above the output of a monofacial module of equivalent nominal power. The effect is most pronounced in ground-mounted installations elevated on taller racking structures, where reflected irradiance on the rear face is maximized. ### Will the GKA182N132 panels withstand Polish winters with heavy snowfall and strong winds? Modules in this series are certified for a snow load of up to 5,400 Pa and a wind load of up to 2,400 Pa. These ratings are sufficient for the vast majority of locations across Poland, including mountainous regions with heavier snow accumulation. The anodized aluminum frame combined with 3.2 mm tempered glass provides the mechanical resilience needed to withstand demanding weather conditions year-round. ### How many Gamko GKA182N132 550 W panels do I need for a typical 10 kWp residential installation? Achieving a peak power of 10 kWp requires just 19 GKA182N132 550 W modules (19 × 550 W = 10,450 W). By comparison, older 400 W panels would require 25 units to reach a similar capacity. The lower module count reduces installation labor costs, minimizes the number of electrical connections, and provides greater flexibility in array layout - particularly valuable when available roof space is constrained. ### Is the GKA182N132 series resistant to PID, and what risk does PID pose to a photovoltaic installation? Yes, GKA182N132 modules carry certified resistance to PID (Potential Induced Degradation). PID is a progressive power loss mechanism caused by leakage currents flowing between the cells and the module frame, and is particularly severe in large string-configured systems operating at high DC voltages. Without adequate PID protection, power output losses of ten percent or more can accumulate within just a few years of operation. Thanks to the N-TOPCon cell architecture, this risk is effectively eliminated across the entire GKA182N132 series. ## 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 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.
