Light for its output, weak in heat
The Gamko New Energy GKA182N144 series consists of modules based on N-TOPCon cells, designed for high efficiency and stable operation in Polish conditions. The use of a half-cut architecture and multi-busbar technology helps to minimize internal losses and improve performance, especially when partial shading from chimneys or skylights occurs on the roof. This is a good choice for investors who want to "extract" more energy from the same area - without compromising durability.
The GKA182N144 stands out due to its PID resistance, which translates into a significantly lower risk of power degradation over a longer period of operation. Another advantage is improved performance in low-light conditions thanks to the refined surface texture of the cells and glass - which is particularly important during the autumn and winter seasons or in cloudy weather.
This series is suitable for both premium residential installations and commercial systems on roofs of halls, where efficiency, reliability, and predictable performance are key.

Top 1% of the TOPCon 600-650 W segment, against a median of 53.1. Ranked 186th in the whole database.
Top 21% of the TOPCon 600-650 W segment, against a median of 22.80%.
Top 24% of the TOPCon 600-650 W segment, against a median of 227.7.
Bottom 19% of the TOPCon 600-650 W segment, against a median of -0.290.
A peak efficiency of 23.99% clearly outperforms direct competitors: HT-SAAE HT66-18X(ND)-F (23.0%), MY Solar G&A TOPCon (22.95%), and Weran Solar LR7-72HTH (23.0%). On roof space-constrained installations, this translates into measurably higher annual energy yield without increasing the module count.
N-type cells exhibit a lower LID degradation rate (below 2% in year one vs. ~3% for PERC) and a more favorable temperature coefficient of power. The bifacial design captures an additional 5-25% of energy from reflected irradiance, depending on ground albedo and mounting angle.
The manufacturer offers a linear power output warranty of 30 years - exceeding the 25-year standard common among many manufacturers in this class. The product workmanship warranty is 12 years, which is typical for this market segment.
Modules are certified to IEC 61215 and IEC 61730 (durability and electrical safety) and are rated for mechanical loads of 2,400 Pa wind and 5,400 Pa snow - values consistent with Polish snow load zones II-III and typical wind loads per PN-EN 1991-1-3.
Guaranteed PID resistance limits power degradation in high-voltage systems (typical string voltages of 1,000-1,500 V). Advanced cell and glass surface texturing improves responsiveness under diffuse irradiance - a meaningful advantage in Polish climatic conditions, where average insolation ranges from 1,650 to 1,900 kWh/m²/year.
Gamko New Energy does not appear on the official BloombergNEF Tier 1 module manufacturer list (March 2026 methodology). This may present a limitation when seeking financing for commercial installations from banks and project funds that conditionally require modules from BNEF Tier 1-listed manufacturers. Comparable series (HT-SAAE, MY Solar, Weran Solar) are in the same position, making this a segment-wide characteristic rather than an issue specific to this series.
The series spans a power range of 580-620 Wp at efficiencies of 22.44%-23.99% - a spread of 1.55 percentage points. When placing an order, it is critical to confirm the exact variant: the entry-level module (580 Wp, ~22.44%) performs significantly worse than the top-tier model (620 Wp, ~23.99%), and overlooking this distinction can result in actual system yield falling short of design estimates.
- Efficiency of 23.2% matches the TOPCon 600-650W median
- At 232.2 W/m² power density, this panel generates 4.5 W/m² more per unit area than TOPCon 600-650W median (227.7 W/m²)
- Temperature coefficient of -0.30%/°C matches the TOPCon 600-650W median
- 25.0 kg weight - 7.8 kg lighter than TOPCon 600-650W median (32.8 kg), reducing installation effort
- Ranked #1332 out of 14129 panels for efficiency in the database
