In practice, this translates to better energy yield under partial shading conditions - a meaningful advantage in typical rooftop installations where uniform irradiance is rarely achievable. - **30-Year Power Warranty (84.8%)** - The manufacturer guarantees at least 84.8% of rated power output after 30 years of operation, a figure comparable to the warranties offered by leading Tier-1 suppliers. For projects with a 20-25 year investment horizon, this is a tangible factor in LCOE calculations. - **Positive Power Tolerance Only** - The 440-460 Wp power range with a 0/+5 W tolerance ensures that no module ships below its rated nameplate value. This makes string design more straightforward and means real-world system output meets or exceeds design projections. - **Certified PID Resistance** - The modules carry certified resistance to Potential Induced Degradation (PID), which is especially important in systems with long DC cable runs, high DC bus voltage, and high-humidity environments - conditions typical of utility-scale PV plants and industrial installations. - **Robust Mechanical Strength** - Certified to withstand a snow load of 5,400 Pa and a wind load of 2,400 Pa, these modules can be installed in climatic zones with heavy snowfall and high wind exposure (zones I-III per PN-EN 1991-1-3) without requiring additional reinforced mounting structures. ## Cons - **Efficiency ~2 pp Below Comparable TOPCon Modules** - The series peaks at 21.02% module efficiency, while direct competitors in the same power class - the Risen RSM96-11-440-460BNDG at 23.00% and the SunKean SKT440~460M12-96D4 at 23.02% - demonstrate the gap clearly. A ~2 percentage point efficiency deficit means that, for the same roof area, a system built around the GKA166M144 will generate approximately 9-10% less energy than N-type modules from a comparable price segment. - **PERC Being Displaced by TOPCon and HJT** - Launched in 2022, the series is based on PERC technology, which has been steadily phased out of mass production since 2023-2024 in favor of TOPCon and HJT. By 2025, TOPCon's share of global module shipments exceeded 70% (per Wood Mackenzie). Choosing PERC today means investing in a technology with a shrinking ecosystem and a widening efficiency gap relative to current-generation products. - **Manufacturer Not Listed on Tier-1 Rosters** - Gamko New Energy does not appear on the BNEF or RENVU Tier-1 module manufacturer lists for 2024-2025. This may be a consideration for bank financing of utility-scale PV projects - many lenders require modules from Tier-1 manufacturers - as well as for the future resale of installations. ## About this series The Gamko New Energy GKA166M144 series consists of monocrystalline modules based on PERC technology, designed for stable operation in real rooftop and ground-mounted conditions. The use of half-cut architecture and **MBB technology** improves power generation and reduces losses in connections, resulting in better energy production even with partial shading and in less sunny conditions. The **PID resistance** is also noteworthy, which is important in installations exposed to more demanding conditions and long cable runs. The modules have **positive power tolerance**, which makes string design easier without the risk of actual performance falling below the expected level. The design is prepared for operation in a demanding environment thanks to tests for resistance to corrosive factors such as **salt fog and ammonia**. This is a reasonable choice for installers and investors looking for predictable performance in residential, commercial, and PV farm applications. ## Notable figures - Module efficiency of 20.6% is 1.9pp below average for \*\*TOPCon 450-500W\*\* panels (median: 22.5%) - Power density of 205.7 W/m² is 19.5 W/m² below \*\*TOPCon 450-500W\*\* median (225.2 W/m²) - needs more roof space - Temperature coefficient of -0.36%/°C is 0.07pp worse than \*\*TOPCon 450-500W\*\* median (-0.29%/°C) - higher losses in summer heat - At 21.0 kg, this panel is 3.0 kg lighter than \*\*TOPCon 450-500W\*\* median (24.0 kg) - easier handling during installation - In the top 80% for efficiency among all TOPCon panels ## Questions ### What warranty is provided for the Gamko New Energy GKA166M144 panels? The GKA166M144 series comes with a 12-year product warranty covering manufacturing defects and structural integrity, as well as a 30-year linear power output warranty. The linear warranty guarantees that after three decades of operation, the module will retain at least the manufacturer-specified minimum percentage of its nominal power. Thanks to the positive power tolerance, real-world output from day one meets or exceeds the declared 460 W rating. ### Are the Gamko GKA166M144 panels suitable for a pitched roof with partial shading? Yes. The half-cut cell architecture - 144 cells divided into two independent halves - ensures that shading from a chimney, antenna, or dormer window affects only a portion of the module rather than the entire string. Multi Busbar (MBB) technology further shortens current flow paths, reducing resistive losses. As a result, the GKA166M144 generates more energy under typical rooftop conditions than legacy full-cell modules. ### What is PERC technology and why does the GKA166M144 series use it? PERC (Passivated Emitter and Rear Cell) is a monocrystalline cell technology that incorporates an additional passivation layer on the rear side of the cell. This layer suppresses charge carrier recombination, resulting in higher solar energy conversion efficiency compared to standard monocrystalline cells. In the GKA166M144 series, PERC works in concert with the half-cut cell design and MBB technology, delivering consistent energy production under both full irradiance and diffuse light conditions. ### Are the Gamko GKA166M144 modules resistant to harsh weather and environmental conditions? Yes. The series has passed salt mist and ammonia resistance tests, confirming its suitability for coastal, agricultural, and industrial installations. The module structure withstands wind loads up to 2,400 Pa and snow loads up to 5,400 Pa, making it safe for deployment in Polish climate conditions where heavy snowfall is common. ### Is the GKA166M144 series resistant to PID degradation, and why does that matter? Yes, the GKA166M144 modules have verified resistance to PID (Potential Induced Degradation). PID is a power loss phenomenon caused by high string voltage combined with moisture, and it is particularly detrimental in large-scale installations with long cable runs and utility-scale PV farms. PID resistance ensures that the module maintains its rated power output throughout the entire warranty period without significant losses attributable to this effect. ### Are the 460 W Gamko GKA166M144 panels suitable for residential installations, or only for utility-scale PV farms? The GKA166M144 is well suited for residential, commercial, and utility-scale PV applications alike. The 440-460 W power range falls within the standard for prosumer systems, and features such as positive power tolerance and PID resistance are equally valuable in small-scale installations. It is advisable, however, to verify that the inverter supports the open-circuit voltage (Voc) characteristic of 144-cell modules in this format, and to consult a certified installer for proper system sizing. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/GKA166M144-440-460W-bcddac4ffc88.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +45 W, cooler, +4.2 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +40 W, cooler, +3.9 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +50 W, cooler, +3.9 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +50 W, cooler, +3.9 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +50 W, cooler, +3.9 pp | | [GCL GCL-NR10R/54BGDF](https://comparepv.com/panel/gcl-gcl-nr10r-54bgdf) | 500 W | +50 W, cooler, +3.9 pp | | [Gamko New Energy GKA166M144 (440W class)](https://comparepv.com/panel/gamko-new-energy-gka166m144-440w-class) | 440 W | -10 W, -0.5 pp | | [Gamko New Energy GKA166M144 (445W class)](https://comparepv.com/panel/gamko-new-energy-gka166m144-445w-class) | 445 W | -0.2 pp | | [Gamko New Energy GKA166M144 (455W class)](https://comparepv.com/panel/gamko-new-energy-gka166m144-455w-class) | 455 W | +0.2 pp | | [Gamko New Energy GKA166M144 (460W class)](https://comparepv.com/panel/gamko-new-energy-gka166m144-460w-class) | 460 W | +10 W, +0.4 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +140 W, cooler, +3.2 pp | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +135 W, cooler, +3.1 pp | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +130 W, cooler, +2.9 pp | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +130 W, cooler, +2.9 pp | --- Source: https://comparepv.com/panel/gamko-new-energy-gka166m144-450 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
