This translates into meaningfully higher energy yield from a limited roof area, which is especially critical for prosumer installations. - **Bifacial Design – Energy Harvest from Both Sides** - The bifacial cell architecture generates additional energy from ground-reflected irradiance (albedo), which under typical mounting conditions — light-colored roofing membrane, gravel, or snow — delivers a yield gain of 5–15% compared to the monofacial modules used by direct competitors in this power class. - **30-Year Product and Power Warranty** - The manufacturer provides both a 30-year product warranty and a 30-year linear power output warranty, exceeding the industry-standard 25-year term used by Jinko, JA Solar, and Trina Solar in comparable product lines. The extended warranty horizon directly improves project bankability and IRR. - **Half-Cut + Multi-Busbar – Minimized Internal Losses** - Half-cut cell technology reduces internal cell resistance by approximately 50%, while the multi-busbar (MBB) layout shortens the electron path and limits power losses under partial shading. In practice, the GKA182M series maintains higher energy yield under non-uniform irradiance than older full-cell, non-MBB designs used by Solitek and Lina Energy. - **Robust Mechanical Strength and Certifications** - Modules are certified to IEC 61215 and IEC 61730, rated for wind loads of 2,400 Pa and snow loads of 5,400 Pa, and carry certified resistance to salt mist and ammonia. A three-stage quality control process — EL testing, flash testing, and an automated production line — minimizes the risk of hidden microcracks. ## Cons - **100–285 Wp Power Range – Niche Market Segment** - The series peaks at 285 Wp, while the prosumer and commercial markets in Poland currently operate with 400–600 Wp modules. A 10 kWp system requires approximately 35 GKA182M panels (285 W) versus roughly 20 panels at 500 W, resulting in higher BoS costs (mounting hardware, cabling, and labor). The series is optimally positioned for mobile, marine, and off-grid applications rather than conventional rooftop prosumer installations. - **No Confirmed BNEF Tier 1 Status** - Gamko New Energy (capacity ~1.2 GW/year based on 2023 data) does not appear on publicly available Bloomberg NEF Tier 1 lists — the standard required by banks and insurers when financing larger PV projects. For commercial installations above 100 kWp, this may present a barrier during financial due diligence. ## About this series The Gamko New Energy GKA182M panel series is an advanced solution based on M10-type monocrystalline cells, setting new efficiency standards for prosumer and commercial installations. Thanks to the use of **Half-Cut and Multi-Busbar (MBB)** technology, these modules effectively minimize energy losses resulting from internal resistance and partial shading. This design directly translates into a higher energy yield per square meter, which is crucial when mounting space on roofs is limited. These panels solve the problem of power degradation over time, offering exceptional **PID resistance** and excellent mechanical stability in harsh weather conditions, such as strong winds or heavy snow loads. The GKA182M series stands out from the competition with an **optimized temperature coefficient**, allowing it to maintain high efficiency even on very hot days when standard modules lose performance more quickly. It is an ideal choice for investors seeking a balance between modern technology and a quick return on investment. Additionally, the **high transmittance of the tempered glass** and the reinforced frame construction ensure many years of trouble-free operation, making this series one of the most substantial choices in its price segment. ## Notable figures - Efficiency of 23.0% is 3.6pp above the \*\*PERC 0-400W\*\* median (19.4%) - 208.1 W/m² power density - 13.7 W/m² more than \*\*PERC 0-400W\*\* median (194.4 W/m²), more power per roof area - Weight of 9.0 kg (11.5 kg below \*\*PERC 0-400W\*\* median of 20.5 kg) allows easier transport and roof mounting - Ranked #1919 out of 14005 panels for efficiency in the database ## Questions ### What warranty is offered on the Gamko New Energy GKA182M panels? The GKA182M series comes with a 30-year product warranty and a 30-year power output warranty. This means that for three decades the manufacturer is liable for both physical defects in the module and for maintaining the minimum efficiency specified in the warranty certificate. This is one of the longest warranty packages available on the market and significantly reduces the financial risk of the entire photovoltaic investment. ### What is TOPCon technology and why was it chosen for the GKA182M series? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that minimizes recombination losses at the silicon surface. In the GKA182M series this translates into higher module efficiency compared to older PERC panels, superior performance under low-irradiance conditions (overcast days, early mornings), and virtually zero light-induced degradation (no LID effect). The result is a measurably higher annual energy yield. ### Are the GKA182M panels bifacial, and does that make sense on a pitched roof? Yes, the GKA182M series consists of bifacial modules that generate current from both sides — the front face (direct irradiance) and the rear face (irradiance reflected from the substrate). On pitched roofs the bifacial gain is smaller than in ground-mounted systems, but it still delivers a few percent increase in yield, especially when the roof surface is covered with a light-colored membrane or gravel. The greatest benefit is achieved by maintaining a ventilation gap between the module and the roof surface. ### Does the Gamko GKA182M panel lose a significant amount of power on hot days? Thanks to TOPCon technology, the GKA182M series features an optimized temperature coefficient of power (approximately -0.35%/°C), which is lower than that of typical PERC modules. In practice, when a cell heats up to 65°C during summer, the panel loses proportionally less power than older modules. This means higher yield during the hottest months, when solar irradiance is at its peak and elevated temperatures can substantially reduce the efficiency of lower-grade panels. ### Can the GKA182M panels withstand snow loads and strong winds typical of Polish weather conditions? Yes. Modules in the GKA182M series are certified for a snow load of up to 5,400 Pa and a wind load of up to 2,400 Pa. In practical terms, this corresponds to resistance against several hundred kilograms of wet snow and extremely powerful wind gusts. The reinforced aluminum frame and high-transmittance tempered glass ensure years of trouble-free operation even in mountainous regions of Poland with heavy snowfall and gusty winds. ### How many Gamko GKA182M panels do I need for a residential installation of 6 or 10 kWp? The peak power output of a single GKA182M module is up to 285 Wp. A 6 kWp system requires approximately 21–22 panels, while a 10 kWp system requires approximately 35–36 modules. The exact number depends on the available roof area, the tilt angle and orientation of the roof surface, and the household's annual energy consumption. It is advisable to consult an installer who will factor in local irradiance conditions and any potential shading. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/2024-GAMKO-CATALOG-MOBILE-48-8a7a81e40e9e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Gamko New Energy GKA182M160W](https://comparepv.com/panel/gamko-new-energy-gka182m160w) | 160 W | +10 W | | [Gamko New Energy GKA182M180W](https://comparepv.com/panel/gamko-new-energy-gka182m180w) | 180 W | +30 W | | [Gamko New Energy GKA182M200W](https://comparepv.com/panel/gamko-new-energy-gka182m200w) | 200 W | +50 W | | [Gamko New Energy GKA182M120W](https://comparepv.com/panel/gamko-new-energy-gka182m120w) | 120 W | -30 W, lighter | | [Gamko New Energy GKA182M135W](https://comparepv.com/panel/gamko-new-energy-gka182m135w) | 135 W | -15 W, lighter | | [Gamko New Energy GKA182M100W](https://comparepv.com/panel/gamko-new-energy-gka182m100w) | 100 W | -50 W, lighter | | [Gamko New Energy GKA182M110W](https://comparepv.com/panel/gamko-new-energy-gka182m110w) | 110 W | -40 W, lighter | | [JA Solar NS-100MH-36](https://comparepv.com/panel/ja-solar-ns-100mh-36) | 100 W | -50 W, -1.7 pp, -5 yr warranty | | [PolyCrown Solar Tech NS-100MH-36](https://comparepv.com/panel/polycrown-solar-tech-ns-100mh-36) | 100 W | -50 W, -1.7 pp, -5 yr warranty | | [LinkSol LKS-5M-115](https://comparepv.com/panel/linksol-lks-5m-115) | 115 W | -35 W, lighter, -5.8 pp | | [LinkSol LKS-5M-110](https://comparepv.com/panel/linksol-lks-5m-110) | 110 W | -40 W, lighter, -6.5 pp | | [Waaree WS-110 /12V](https://comparepv.com/panel/waaree-ws-110-12v) | 110 W | -40 W, -7.2 pp, -20 yr warranty | | [LinkSol LKS-5M-105](https://comparepv.com/panel/linksol-lks-5m-105) | 105 W | -45 W, lighter, -7.3 pp | | [Waaree WS-105 /12V](https://comparepv.com/panel/waaree-ws-105-12v) | 105 W | -45 W, -8.0 pp, -20 yr warranty | --- Source: https://comparepv.com/panel/gamko-new-energy-gka182m150w Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
