Light for its output, no clear weak spot
The Gamko GKA182N132 photovoltaic panel series utilizes innovative N-type TOPCon cell technology, placing it at the forefront of solutions in terms of efficiency and durability. The use of large 182 mm silicon wafers combined with a half-cut design significantly reduces resistance losses, which translates into stable module operation even in difficult lighting conditions typical for the Polish climate. A key advantage of this series is its exceptionally low temperature coefficient, thanks to which the panels maintain high efficiency on hot days when traditional modules lose power. The use of N-type cells effectively eliminates the problem of light-induced degradation (LID), guaranteeing investors a longer lifespan and higher energy yields over decades of operation. This solution is dedicated primarily to large commercial installations and demanding prosumers looking for an optimal balance between modern technology and a fast return on investment. The solid frame construction ensures high resistance to mechanical loads, such as heavy snow or strong wind, making the GKA182N132 series a safe choice for rooftop and ground-mounted farms. Thanks to precise quality control, these panels offer consistent parameters, which sets them apart from standard products available on the market.

The top-tier variant in this series achieves 23.16% module efficiency, while directly comparable products - Goldi Solar GS10-B144-TF, IBC Solar 182M, and S-Energy SL65-72BGJ - top out at 21.3%. The ~1.86 percentage-point advantage translates into meaningfully higher energy yield from the same roof or ground area.
N-type TOPCon cells eliminate light-induced degradation (LID), which in legacy PERC modules can cause up to 2-3% power loss during the first months of operation. The lower temperature coefficient inherent to this technology also ensures higher power output on hot days, which is particularly relevant during summer generation peaks in Poland.
The bifacial construction enables absorption of irradiance reflected from the ground surface. In ground-mounted installations with a light-colored substrate or snow cover, this can increase annual energy yield by 5-15% compared to a monofacial module of equivalent STC power rating.
The manufacturer provides a 30-year performance warranty, exceeding the 25-year standard offered by most peers in this price class (Goldi Solar, S-Energy). For commercial installations with longer financing horizons, this represents a significant advantage in LCOE analysis.
Certified mechanical load ratings per IEC 61215 (5400 Pa snow, 2400 Pa wind) make this series well suited for Polish climatic conditions, including mountainous regions with heavy snowfall, without requiring additional structural reinforcements.
Gamko New Energy (annual production capacity ~1.2 GW as of 2023 data) does not appear on the BloombergNEF Tier 1 or Wood Mackenzie H1 2025/Q1 2026 module lists, which serve as the reference standard for institutions financing utility-scale PV projects. This may complicate or preclude bank financing for larger commercial installations that require a bankable equipment list.
- At 23.2% efficiency, this panel is 0.7pp above typical TOPCon 550-600W modules (median: 22.4%)
- Power density of 231.6 W/m² packs 7.2 W/m² more into the same footprint vs TOPCon 550-600W median (224.4 W/m²)
- Temperature coefficient of -0.30%/°C matches the TOPCon 550-600W median
- Weight of 23.0 kg (8.2 kg below TOPCon 550-600W median of 31.2 kg) allows easier transport and roof mounting
- Ranked #1533 out of 14129 panels for efficiency in the database
