Efficiency leader, no clear weak spot
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.

GKA182M modules achieve a cell efficiency of 23%, while comparable products in the same power class — Lina Energy LPEPV 60 SUPERIOR and SP Enerji P60 — top out at 17.52%, and the Solitek SOLID Solrif at 14.45%. This translates into meaningfully higher energy yield from a limited roof area, which is especially critical for prosumer installations.
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.
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 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.
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.
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.
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.
- At 23.0% efficiency, this panel is 7.0pp above typical TOPCon 0-400W modules (median: 16.0%)
- At 241.0 W/m² power density, this panel generates 81.2 W/m² more per unit area than TOPCon 0-400W median (159.8 W/m²)
- Weight of 10.8 kg (12.7 kg below TOPCon 0-400W median of 23.5 kg) allows easier transport and roof mounting
- In the top 14% for efficiency among all TOPCon panels
