Light for its output, weak in heat
The Gamko New Energy GKA210N132 series consists of large-format modules based on N-type monocrystalline cells using the TOPCon technology, designed to maximize energy yield for a given surface area. In practice, they stand out due to their high efficiency and stable operation in demanding conditions - which is particularly important in Poland, with its variable weather and frequent periods of reduced solar irradiance. The manufacturer also emphasizes PID resistance, which helps to reduce the risk of accelerated degradation in installations operating at higher voltages.
The GKA210N132S Standard version is a versatile choice for PV farms and commercial installations. The GKA210N132BK Black version is ideal for applications where aesthetics are important, such as representative roofs of service buildings. The GKA210N132BF Bifacial, with its bifacial design and commonly used glass-on-glass system, allows for better utilization of reflected light, which is particularly beneficial in bright environments, in ground-mounted and carport systems. This series is for investors who expect real benefits in terms of yield, durability, and the flexibility to choose the version that best suits their project.
Ranking
Signals from the data
Commercial and utility-scale.
Hot climates, roofs where every square metre has to count and tight roof space.
Top 10% of the TOPCon 700-750 W segment, against a median of 52.9. Ranked 847th in the whole database.
Bottom 4% of the TOPCon 700-750 W segment, against a median of -0.290. Ranked 8,846th in the whole database.
Bottom 7% of the TOPCon 700-750 W segment, against a median of 230.2. Ranked 4,048th in the whole database.
Bottom 11% of the TOPCon 700-750 W segment, against a median of 23.00%.
The peak efficiency of 23.18% is identical to that of direct peer Renesola RS9-700~720NBG-E1 (23.18%) and only 0.02 percentage points below the DMEGC DMxxxG12T-B66HSW (23.2%). The series therefore ranks at the very top of large-format 700-720 W modules available on the market in 2025-2026.
N-type TOPCon cells are free from boron-oxygen-induced LID and exhibit no LeTID, with an annual degradation rate of ≤0.40%/year compared to 0.45-0.55%/year for PERC modules. Over a 30-year project lifetime, this translates into measurably higher cumulative energy yield from the same installed area.
Gamko provides a linear power output warranty for 30 years, with first-year degradation ≤1% and ≤0.4% per year thereafter. The market standard for PERC modules is 25 years; the extended warranty directly lengthens the horizon of guaranteed revenue for PPA projects.
The GKA210N132BF glass-glass configuration enables an additional 5-15% energy gain from reflected irradiance (albedo) in typical ground-mount installations and carports over light-colored surfaces. A bifaciality factor of 85% is on par with the best bifacial TOPCon modules in this power class.
Certified load ratings of 2,400 Pa (wind) and 5,400 Pa (snow) satisfy the requirements for the vast majority of locations in Poland in accordance with EN 1991-1-3, simplifying engineering procedures for both rooftop and ground-mount installations.
Gamko New Energy does not appear on the BNEF Tier 1 list (Q1 2026 or any prior edition), meaning its bankability has not been independently confirmed - a requirement imposed by most commercial lenders for PV project financing above 10 MW. Projects requiring project finance may need additional due diligence or module warranty insurance.
Gamko's annual production capacity was approximately 1.2 GW in 2023, while leading Tier 1 manufacturers (JA Solar ~80 GW, Trina Solar ~50 GW) operate at many times that capacity. For large orders (>5 MWp), this may introduce supply-chain timing risk and reduce pricing stability under long-term procurement contracts.
- At 22.5% efficiency, this panel is on par with typical TOPCon 700-750W modules
- At 225.3 W/m², this panel generates 4.9 W/m² less per unit area than TOPCon 700-750W median (230.2 W/m²)
- Temperature coefficient of -0.34%/°C is 0.05pp worse than TOPCon 700-750W median (-0.29%/°C) - higher losses in summer heat
- Weight of 32.0 kg (6.0 kg below TOPCon 700-750W median of 38.0 kg) allows easier transport and roof mounting
- Bifacial design (100% factor) captures reflected light - adds 5-15% yield on ground-mount or white roof
