Bifacial light absorption delivers a real-world yield gain of 8-15% on rooftop installations and 20-30% on ground-mounted systems with high-albedo surfaces, translating into higher annual energy yield without increasing the installation footprint. - **21.28% Efficiency - Among Top Peers in Its Class** - The maximum module efficiency of 21.28% matches that of the IBC Solar 182M Half Cell 540-550W and sits only 0.02 percentage points below the Goldi Solar GS10-B144-TF and S-Energy SL65-72BGJ (both at 21.3%). The series therefore sacrifices nothing in power density relative to its direct competitors in this cell format. - **30-Year Linear Power Warranty** - Gamko offers a 30-year linear power output warranty - exceeding the 25-year standard common among most mainstream Chinese manufacturers. The extended warranty horizon directly improves bankability for externally financed projects and supports stronger IRR figures in 25+ year financial models. - **Wide Power Range: 10 Variants from 530 to 550 Wp** - Availability across 10 variants spanning 530-550 Wp allows precise module selection to match a fixed number of strings without exceeding inverter input limits - particularly valuable for expanding existing installations or projects subject to strict grid connection power caps. - **IEC 61215 and IEC 61730 Certified** - The modules carry IEC 61215 (performance and durability testing) and IEC 61730 (electrical safety) certifications, and according to ENF Solar data also hold CE, ISO 9001, and ISO 14001 marks. This full certification package enables installation and subsidy eligibility under national support programs (Mój Prąd, KPO) without risk of rejection during audits. ## Cons - **PERC, Not TOPCon - Older Cell Technology** - In 2025-2026, the premium segment for the 182 mm format is broadly migrating to TOPCon (N-type) technology, which exhibits approximately 0.3-0.5% lower annual LID degradation rate and a better temperature coefficient (approx. -0.30%/°C vs. -0.35%/°C for PERC). Over the 30-year warranty horizon, this translates into measurably lower cumulative energy yield compared to manufacturers that have already transitioned to N-type in this power class. - **Not Listed as Tier-1 by BNEF** - Gamko New Energy (1.2 GW of manufacturing capacity in 2023) does not appear on Bloomberg NEF's Tier-1 Module Manufacturer lists. For installations financed through bank loans or institutional leasing, this may create difficulties in obtaining lender module approval and result in less favorable residual value insurance terms compared to Tier-1 manufacturers. - **12-Year Product Warranty - Below Premium Standard** - A 12-year workmanship warranty is the norm for Chinese mid-tier suppliers, but falls noticeably short of the 15-25 years offered by European and Korean manufacturers in a comparable price bracket (e.g., IBC Solar at 15 years). In longer-term commercial installations, this gap directly affects the cost of potential module replacements once the manufacturer's product warranty has expired. ## About this series The Gamko New Energy GKA182M144 series consists of modules with a large active area, designed to maximize energy yield in a limited mounting space. The use of **monocrystalline PERC cells** and a **half-cut (semi-cut) design** helps minimize losses and improves panel performance even with partial shading - a common occurrence in Poland due to chimneys, skylights, or trees. The **MBB multi-busbar design** also enhances current collection and supports stable operation in everyday conditions. The GKA182M144 is suitable for both high-end residential installations and larger commercial and industrial projects, where rapid power generation and predictable energy production are crucial. Thanks to its refined design, the module performs well even in less sunny conditions, and its **resistance to degradation and long-term performance** sets it apart from many standard panels in this segment. ## Notable figures - Efficiency of 20.9% is 1.8pp below the \*\*TOPCon 500-550W\*\* median (22.7%) - 208.9 W/m² power density is 18.5 W/m² below \*\*TOPCon 500-550W\*\* median (227.4 W/m²) - requires larger installation area - -0.36%/°C temperature coefficient - 0.07pp worse than \*\*TOPCon 500-550W\*\* median (-0.29%/°C), expect higher hot weather losses - At 25.0 kg, this panel is 2.0 kg lighter than \*\*TOPCon 500-550W\*\* median (27.0 kg) - easier handling during installation - #10369 for efficiency, #12425 for temperature performance out of 14129 panels ## Questions ### What warranty does the Gamko New Energy GKA182M144 panel series carry? The GKA182M144 series comes with a 12-year product warranty covering material and manufacturing defects, along with a 30-year power output warranty. This means the module is guaranteed to maintain the manufacturer-specified performance level for three decades. These are standard premium-segment terms, comparable to those offered by leading Asian manufacturers. ### Is the Gamko New Energy GKA182M144 a bifacial panel, and what does that mean in practice? Yes, the GKA182M144 series is a bifacial module, meaning it collects light on both sides. The rear surface captures light reflected from the ground - such as a light-colored roofing membrane, gravel, or snow - which can increase energy yield by several to over ten percent compared to a conventional monofacial panel. The gain is most pronounced when the albedo of the surface below is sufficiently high and the mounting angle is optimized accordingly. ### What is the peak power of the highest-wattage variant in the GKA182M144 series, and is it suitable for a small residential installation? The top variant in the series is rated at 550 Wp. For a typical residential system of 6-10 kWp, only 11-19 modules are required, which translates to fewer modules and fewer BoS mounting components compared to lower-wattage alternatives. The series is well suited to both prosumer rooftop installations and larger commercial projects where reaching the target capacity quickly is a priority. ### Can the GKA182M144 panels handle a Polish winter and snow loads? Yes. The GKA182M144 series modules are certified for a snow load of up to 5,400 Pa and a wind load of up to 2,400 Pa, satisfying the structural requirements for the vast majority of locations in Poland. The half-cut cell layout combined with MBB technology also improves performance under diffuse irradiance conditions typical of overcast autumn and winter months. ### How do the PERC cells in the GKA182M144 series differ from standard monocrystalline cells? PERC (Passivated Emitter and Rear Cell) cells feature an additional passivation layer on the rear side of the cell that reduces charge-carrier recombination, enabling higher conversion efficiency than conventional monocrystalline cells. Combined with the half-cut cell configuration and multi-busbar (MBB) design, this translates to better performance under partial shading conditions and lower long-term degradation. ### Is Gamko New Energy a reputable manufacturer and can they be trusted? Gamko New Energy (Nantong Gamko New Energy Co., Ltd.) is a Chinese PV module manufacturer with an annual production capacity exceeding 1.2 GW. The company is listed in the ENF Solar directory and holds certifications for durability in aggressive environments, including salt mist and ammonia resistance. The brand is less widely recognized in Poland than market leaders, so it is advisable to verify the local distributor's credentials and confirm the availability of in-country warranty service before purchasing. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/GKA182M144-530-550W-744449ed5433.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | -30 W, cooler, +4.1 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | -45 W, cooler, +3.9 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +20 W, cooler, +3.9 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | -35 W, cooler, +3.8 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | -35 W, cooler, +3.8 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +15 W, cooler, +3.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | -50 W, cooler, +3.6 pp | | [Gamko New Energy GKA182M144-530W](https://comparepv.com/panel/gamko-new-energy-gka182m144-530w) | 530 W | -10 W, -0.4 pp | | [Gamko New Energy GKA182M144-535W](https://comparepv.com/panel/gamko-new-energy-gka182m144-535w) | 535 W | Very close match | | [Gamko New Energy GKA182M144-545W](https://comparepv.com/panel/gamko-new-energy-gka182m144-545w) | 545 W | Very close match | | [Gamko New Energy GKA182M144-550W](https://comparepv.com/panel/gamko-new-energy-gka182m144-550w) | 550 W | +10 W, +0.4 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +110 W, cooler, +4.3 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +105 W, cooler, +4.1 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +100 W, cooler, +3.9 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +95 W, cooler, +3.7 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +90 W, cooler, +3.5 pp | --- Source: https://comparepv.com/panel/gamko-new-energy-gka182m144-540 Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
