For investors, this translates to greater yield predictability and lower financial risk throughout the full system lifetime. - **Bifacial PERC + Multi-Busbar + Half-Cut Cells** - The combination of bifacial light harvesting, multi-busbar (MBB) technology, and a half-cut cell layout reduces internal resistance and mismatch losses under partial shading - a significant advantage in Poland's climate, which sees a high proportion of diffuse irradiance. The bifacial design can yield an additional 5-15% energy gain with appropriate mounting configurations. - **IP68 Junction Box and High PID Resistance** - The IP68-rated junction box ensures watertight integrity even during prolonged submersion, which is particularly relevant for flat-roof installations where standing water may accumulate. The declared high resistance to PID (Potential Induced Degradation) safeguards long-term performance, especially in high-voltage systems (>1000 V DC). - **Mechanical Load Rating: 5400 / 2400 Pa** - The module is certified for a snow load of 5400 Pa and a wind load of 2400 Pa, meeting the requirements for climate zones with snow load class S2-S3 per EN 1991-1-3 - fully adequate for Polish atmospheric conditions. - **182 mm (M10) Format - High Power Density** - The 182 mm cells arranged in a 132-cell layout (half-cut, 66×2) deliver peak power up to 505 Wp at an efficiency of up to 21.27%, enabling effective use of limited roof area without requiring the larger 210 mm format, which demands wider racking rails. ## Cons - **PERC vs. N-Type: ~1.43 Percentage Points Lower Efficiency** - The maximum efficiency of the GKA182M132 series is 21.27%, while direct N-type TOPCon equivalents - the Sunova Tangra M Pro HD and Q-SUN Qrystal N10 - reach 22.7% at the same peak power of 505 Wp. The ~1.43 percentage-point efficiency gap over the same surface area results in measurably lower specific yield or requires additional modules in space-constrained projects. Furthermore, PERC technology is susceptible to LID (Light-Induced Degradation), a phenomenon that N-type cells are largely immune to. - **Product Warranty Limited to 12 Years** - The workmanship warranty covers only 12 years, whereas Tier-1 manufacturers such as JA Solar, Jinko Solar, and LONGi standardly offer 25 years. The shorter product warranty period represents elevated risk for investors in the event of mechanical or electrical defects occurring after year 12 of operation. - **Gamko Not Listed on BNEF Tier 1** - Nantong Gamko New Energy (annual manufacturing capacity ~1.2 GW per ENF Solar) does not appear on Bloomberg NEF Tier 1 lists or PV Evolution Labs Top Performer rankings - unlike brands such as Jinko, JA, LONGi, or even Sunova. This may result in more difficult access to project finance for large commercial installations where lenders require manufacturer warranties recognized by insurers. ## About this series The Gamko New Energy GKA182M132 series comprises monocrystalline modules based on large-area cells and a half-cut design, specifically engineered for stable operation in rooftop and larger commercial installations. The use of **PERC** technology and a **multi-busbar** construction enhances current collection from the cell and reduces losses, resulting in improved energy production, particularly in partially shaded conditions and under less intense sunlight - common in the Polish climate. The module utilizes tempered glass and a robust aluminum frame, while a sealed connection box with **IP68** protection ensures safe operation on rooftops and in humid environments. A key feature is **high PID resistance**, which helps to minimize power degradation over the long term and increases the predictability of energy yields. The GKA182M132 series is ideal for installers and investors who want to optimize energy yield from limited space and opt for **long-term power warranty** without paying extra for "marketing" add-ons. ## Notable figures - At 21.3% efficiency, this panel is on par with typical \*\*PERC 500-550W\*\* modules - 212.7 W/m² power density - 3.7 W/m² more than \*\*PERC 500-550W\*\* median (209.0 W/m²), more power per roof area - Temperature coefficient of -0.36%/°C matches the \*\*PERC 500-550W\*\* median - At 23.0 kg, this panel is 5.3 kg lighter than \*\*PERC 500-550W\*\* median (28.3 kg) - easier handling during installation - #8918 for efficiency, #12425 for temperature performance out of 14129 panels ## Questions ### What warranty does the Gamko New Energy GKA182M132 series offer? The GKA182M132 series comes with a 12-year product warranty covering physical and material defects, as well as a 30-year power output warranty. After 30 years, the panel is guaranteed to retain at least 84.8% of its nominal output power. These are solid warranty terms for a budget-tier product - comparable to the guarantees offered by leading Tier 1 manufacturers. ### What does it mean that the GKA182M132 panel is bifacial, and does it make sense on a Polish rooftop? Bifacial means the module harvests energy from both the front and rear surfaces - the rear side responds to irradiance reflected from the mounting surface or a light-colored roofing membrane. In Poland, the bifacial gain on a pitched roof is limited (approximately 3-8% additional yield), but it is real in installations with a highly reflective substrate or in ground-mounted dual-tilt configurations. On dark-colored roofs, the difference is minimal. ### Can the Gamko GKA182M132 505 W panel handle heavy snow loads or strong winds? Yes. According to the specification, the module withstands a snow load of up to 5,400 Pa and a wind load of up to 2,400 Pa. These values are fully adequate for typical Polish climatic conditions, including mountainous regions. Tempered glass and an aluminum frame provide structural rigidity, while IEC 61215 and IEC 61730 certifications confirm compliance with applicable safety standards. ### Why is high PID resistance in the GKA182M132 series important for long-term operation? PID (Potential Induced Degradation) is a phenomenon of gradual power loss caused by voltage potential between the cells and the frame, which is aggravated by humidity and elevated temperatures. The GKA182M132 series is engineered for high PID resistance, meaning that real-world energy production after 10-20 years should track more closely to the nominal degradation curve than modules without this protection. This is particularly significant in systems operating at high DC system voltages. ### What are the dimensions and weight of the GKA182M132 panel, and can it be carried onto a roof by hand? The module measures 2,094 × 1,134 × 30 mm and weighs approximately 23 kg. These are typical dimensions for 132-cell modules based on the 182 mm (M10) wafer format. Two-person manual installation on a rooftop is feasible, though the size and weight make it advisable to work in pairs or use a mechanical lift aid. Installers familiar with the M10/182 mm format should have no difficulty integrating these modules into standard racking systems. ### Do Gamko GKA182M132 modules perform efficiently under overcast skies and low winter irradiance? Yes. PERC technology combined with a half-cut cell layout (132 half-cells) and a multi-busbar interconnection scheme improves low-irradiance performance compared to conventional full-cell modules. Module efficiency ranges from 20.42% to 21.27%, and the manufacturer declares strong Low Irradiance performance - which is particularly relevant in Poland, where a significant share of annual energy yield occurs during autumn and winter months and on days with diffuse radiation. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/GKA182M132-485-505W-ab3f3dc564b5.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, +3.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +3.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, +3.4 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | Cooler, heavier, +3.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +50 W, cooler, +3.3 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +3.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | Cooler, +3.2 pp | | [Gamko New Energy GKA182M132S-485](https://comparepv.com/panel/gamko-new-energy-gka182m132s-485) | 485 W | -20 W, -0.8 pp | | [Gamko New Energy GKA182M132S-490](https://comparepv.com/panel/gamko-new-energy-gka182m132s-490) | 490 W | -15 W, -0.6 pp | | [Gamko New Energy GKA182M132S-495](https://comparepv.com/panel/gamko-new-energy-gka182m132s-495) | 495 W | -10 W, -0.4 pp | | [Gamko New Energy GKA182M132S-500](https://comparepv.com/panel/gamko-new-energy-gka182m132s-500) | 500 W | -0.2 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +85 W, cooler, +2.6 pp | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +80 W, cooler, +2.4 pp | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +75 W, cooler, +2.2 pp | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +75 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/gamko-new-energy-gka182m132s-505 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
