Light for its output, weak in heat
The Gamko GKA210N132 panel series is an advanced solution based on N-type TOPCon cell technology, setting new standards for efficiency in the renewable energy sector. The use of large 210 mm silicon wafers allows for achieving impressive power density, which translates directly into space savings and reduced mounting structure costs. These modules effectively solve the problem of limited roof or ground space, generating significantly more energy per square meter compared to older technologies. A key advantage of the series is its exceptional resistance to light and temperature degradation, allowing the system to maintain high efficiency even on hot days or in low-light conditions. The innovative design ensures minimized transmission losses, making these panels an ideal choice for investors building large-scale photovoltaic farms and modern industrial installations. By choosing these modules, you gain stable energy yields in the long term and the assurance that the system will meet the demands of harsh weather conditions. This solution stands out from the competition with a perfect balance between module size and the technological advancement of the active layer, guaranteeing a faster return on investment while maintaining the highest standards of component reliability.
Ranking
Signals from the data
Utility-scale and hot-climate.
Hot climates.
Top 7% of the TOPCon 700-750 W segment, against a median of 52.9. Ranked 524th in the whole database.
Bottom 4% of the TOPCon 700-750 W segment, against a median of -0.290. Ranked 8,778th in the whole database.
The 730–750 W variants achieve 24.14% module efficiency, placing them on par with direct competitors: Tongwei TWMNF-66HD (24.1%), SunEvo EVO 6N (24.1%), and Ocean Solar AOX-132G12HC (24.2%). For utility-scale installations, this translates to a smaller land footprint for the same installed capacity.
N-type TOPCon cells exhibit significantly lower LID degradation (<1%) and a better temperature coefficient (approx. –0.30%/°C) compared to PERC technology (~–0.35%/°C). Bifacial light harvesting typically adds 5–15% in annual energy yield on high-albedo surfaces (e.g., gravel, concrete, snow), resulting in a measurably lower LCOE.
The manufacturer offers a 30-year linear power degradation warranty — the same standard as Tongwei and Ocean Solar in the large-format segment. For externally financed projects, an extended warranty horizon directly improves the risk profile in DCF models.
The use of G12 (210 mm) wafers in a 132-cell configuration delivers 750 Wp per module, reducing unit count, DC terminations, and Balance of System (BoS) costs per installed MW compared to M10 (~182 mm) modules of equivalent total farm capacity.
The series carries IEC 61215 (performance) and IEC 61730 (safety) certifications, along with mechanical load ratings of 2,400 Pa (wind) and 5,400 Pa (snow). CE, ISO 9001, and ISO 14001 certifications are required by a number of financial institutions funding renewable energy projects in the EU.
Gamko New Energy does not appear on any available Bloomberg NEF Tier 1 list (Q1–Q4 2025, Q1 2026). For projects requiring non-recourse financing or technology insurance, the absence of Tier 1 status may present a bankability barrier and complicate access to favorable lending terms.
The 700–720 W variants achieve efficiencies of 22.53–23.18%, approximately 0.9–1.6 percentage points below the peak models of competing manufacturers (Tongwei, Ocean Solar, SunEvo: 24.1–24.2%). In space-constrained installations, these variants deliver noticeably less energy per m², reducing the attractiveness of the lower end of the series portfolio.
The product defect warranty stands at 12 years, whereas Tongwei and other utility-segment manufacturers standardly offer 15 years, and market leaders (e.g., Jinko Tiger Neo, LONGi Hi-MO) provide up to 25 years. The shorter coverage period increases the risk of module replacement costs during the mid-life phase of an installation (years 12–25).
- Efficiency of 23.0% matches the TOPCon 700-750W median
- Power density of 230.2 W/m² matches the TOPCon 700-750W median
- -0.34%/°C temperature coefficient - 0.05pp worse than TOPCon 700-750W median (-0.29%/°C), expect higher hot weather losses
- 32.0 kg weight - 6.0 kg lighter than TOPCon 700-750W median (38.0 kg), reducing installation effort
- Ranked #1797 out of 14005 panels for efficiency in the database
