Light for its output, weak in heat
The Gamko New Energy GKA210N108 series redefines efficiency standards in the residential and commercial rooftop installation segment, based on advanced N-type TOPCon cell technology. The use of 210 mm silicon wafers combined with a 108 half-cut cell design allows for exceptionally high power density while maintaining compact module dimensions. This solves the problem of limited installation space, offering investors maximum energy yield from every square meter of the roof. A key advantage of this series is the near-total elimination of the LID degradation effect and a significantly lower temperature coefficient, which translates into stable operation and higher electricity production on hot days and in low sunlight. Choosing this product line is an investment in long-term reliability, as N-type cells show a much slower decline in efficiency over time than traditional P-type solutions. Excellent low-current characteristics make these panels work perfectly with modern inverters, minimizing transmission losses. This solution is dedicated to demanding users who seek uncompromising quality and want to shorten their return on investment thanks to above-average performance in real-world weather conditions, which clearly distinguishes this series from standard products available on the market.

Top 2% of the TOPCon 550-600 W segment, against a median of 53.8. Ranked 368th in the whole database.

Top 24% of the TOPCon 550-600 W segment, against a median of 224.4.
Bottom 5% of the TOPCon 550-600 W segment, against a median of -0.290. Ranked 8,778th in the whole database.
The top variant in the series achieves 22.71% module efficiency, outperforming directly comparable products such as the Emmvee Titanium Duo/Clear (22.45%) and ZNShine ZXM7-UHLD144 (22.44%). This difference translates into measurably higher energy yield per m² of roof area for any given installation footprint.
The Pmax temperature coefficient is -0.34%/°C, which at a module operating temperature of 65°C (+40°C above STC) results in approximately 1.6 percentage points fewer losses than a typical PERC module (-0.38%/°C). The elimination of LID inherent to N-type cells further limits degradation during the initial years of operation.
The bifacial design enables an additional energy yield of 5–25% from reflected irradiance, depending on ground albedo (e.g., white gravel ~50%, concrete ~25%). Half-cut cells reduce resistive losses and improve resilience to partial shading compared to full-cell modules.
Certified load resistance of 2,400 Pa (wind) and 5,400 Pa (snow), combined with verified resistance to salt mist and ammonia, makes this series suitable for demanding locations — including coastal, agricultural, and industrial rooftop sites — without additional installation restrictions.
The manufacturer guarantees 84.8% of nominal power output after 30 years of operation. A 30-year warranty horizon is uncommon among smaller manufacturers — most offer 25 years — providing a longer, predictable degradation model and reducing investment risk in projects with extended payback periods.
Leading TOPCon manufacturers (Jinko Tiger NEO, Trina Vertex S+, JA Solar Deep Blue 4.0 Pro) standardly offer 15–25 years of product warranty against manufacturing defects. The Gamko GKA210N108's 12-year product warranty falls short by a minimum of 3 years, which is a significant consideration for bank-financed installations or projects with planned service periods exceeding 12 years.
Nantong Gamko New Energy (capacity ~1.2 GW/year) does not appear on the BloombergNEF Tier 1 list for Q1 2026, which is dominated by LONGi, Jinko, Trina, and JA Solar (each at 80+ GW/year). The absence of Tier 1 status may complicate securing project financing above 1 MW and could limit spare-parts availability over a >15-year horizon.
The stated retention of 84.8% output power after 30 years corresponds to an annual degradation rate of ~0.50%/year — higher than that offered by Jinko Tiger NEO (≥87.4%, ~0.40%/year) or JA Solar Deep Blue 4.0 Pro (≥87.4%). On a 10 kWp system, this cumulative difference over 30 years represents approximately 500–700 kWh less total energy generated.
- At 22.7% efficiency, this panel is on par with typical TOPCon 550-600W modules
- Power density of 227.1 W/m² matches the TOPCon 550-600W median
- Temperature coefficient of -0.34%/°C is 0.05pp worse than TOPCon 550-600W median (-0.29%/°C) - higher losses in summer heat
- 25.5 kg weight - 5.7 kg lighter than TOPCon 550-600W median (31.2 kg), reducing installation effort
- Ranked #3285 out of 14005 panels for efficiency in the database
