Light for its output, weak in heat
Gamko New Energy GKA210N120 series panels represent a breakthrough in energy efficiency thanks to the use of advanced N-type TOPCon technology. The use of large silicon cells in the 210 mm (M12) format allows for achieving higher power density, which is crucial for limited installation space on the roofs of residential and commercial buildings. This series effectively eliminates the problem of rapid efficiency loss, offering users a minimal level of light-induced degradation, which translates into higher yields throughout the entire lifecycle of the installation. They stand out from the competition with excellent performance characteristics in diffuse light conditions and high resistance to extreme temperatures, allowing the system to produce more energy in Poland-s real-world weather conditions. These modules are dedicated to demanding investors who focus on maximizing yields per square meter while simultaneously reducing BOS system costs. Thanks to the innovative cell design, the GKA210N120 series ensures exceptional mechanical stability and resistance to micro-cracks, guaranteeing the safety and reliability of the investment for many years. This is a solution that combines modern engineering with economic viability, setting the direction for modern energy-efficient construction and professional solar farms.

Top 3% of the TOPCon 650-700 W segment, against a median of 53.2. Ranked 219th in the whole database.
Bottom 6% of the TOPCon 650-700 W segment, against a median of -0.290. Ranked 8,778th in the whole database.
The GKA210N120 series delivers module efficiency of 23.32–24.03%, clearly outperforming comparable models such as the SpolarPV SPV680 and Solaria panels (21.92%). The 2.1 percentage-point efficiency advantage translates to approximately 60 Wp of additional output from the same roof area at an equivalent nameplate power rating.
N-type TOPCon cells exhibit minimal light-induced degradation (LID <1%) and a more favorable temperature coefficient than legacy P-type PERC cells (~−0.35%/°C). Under typical Polish summer operating conditions with module temperatures of 60–70°C, this results in measurably higher annual energy yield.
The bifacial module construction enables collection of albedo irradiance reflected from the ground surface. With a white roofing membrane or gravel ballast, this typically yields a 5–15% increase in energy output compared to monofacial modules of equivalent front-side power rating.
The manufacturer provides a 30-year linear power warranty, exceeding the current market standard of 25 years offered by manufacturers such as JA Solar and Trina Solar. The extended warranty horizon improves project bankability in project finance structures.
The large-format M12 cells enable 660–680 Wp per module, reducing the total number of modules, connectors, and mounting hardware required for a given system capacity. For a 1 MWp ground-mount array, this equates to approximately 60–80 fewer modules compared to legacy 182 mm formats, directly lowering installation labor and balance-of-system costs.
Gamko New Energy does not appear on the Bloomberg NEF Tier 1 module manufacturer list for Q1 2026 or Q2 2025. This is a practical constraint for utility-scale PV projects seeking financing from independent commercial lenders, which frequently require modules sourced from confirmed Tier 1 manufacturers as a condition of credit approval.
The direct competitor AIKO Comet 3N72 (ABC technology, 680 Wp) achieves 25.2% efficiency versus a maximum of 24.03% for the GKA210N120 — a gap of 1.17 percentage points. On a 100 m² roof, this corresponds to approximately 1.2 kWp less installed capacity, which may be a decisive factor where available roof area is severely constrained.
- At 23.3% efficiency, this panel is 0.9pp above typical TOPCon 650-700W modules (median: 22.4%)
- 233.2 W/m² power density - 9.5 W/m² more than TOPCon 650-700W median (223.7 W/m²), more power per roof area
- Temperature coefficient of -0.34%/°C is 0.05pp worse than TOPCon 650-700W median (-0.29%/°C) - higher losses in summer heat
- At 28.0 kg, this panel is 6.6 kg lighter than TOPCon 650-700W median (34.6 kg) - easier handling during installation
- Ranked #973 out of 14005 panels for efficiency in the database
