The Gamko New Energy GKA210N132 (730W-750W) series is designed to maximize energy generation from a limited surface area - making it particularly suitable for locations where every square meter of roof or ground-mounted structure is valuable. The use of TOPCon monocrystalline cells helps maintain high production even in less sunny conditions and under real-world operating conditions where the module heats up in the summer. The large format with a 132-cell architecture supports stable operation of strings and reduces losses, while tempered glass with an anti-reflective coating improves light utilization in the morning and afternoon hours. In practice, this means faster self-consumption and better return on investment. For B2B investors, long power warranty is also important, which facilitates long-term planning. It is a good choice for PV farms, warehouses, factories, and other energy-intensive facilities, where the advantage lies in the high module power without having to multiply the number of panels.

What owners get
24.14% Efficiency – Segment Peer Leader

Module efficiency of 24.14% outperforms all three direct peer comparables (SunEvo EVO 6N, Tongwei TWMNF-66HD, Sunplus Hi-Max – each at 24.1%), translating into measurably higher energy yield from the same roof area.

Bifacial N-Type TOPCon – Dual-Sided Gain

N-type TOPCon cells exhibit significantly lower LID (Light-Induced Degradation) than PERC technology, while the bifacial construction enables additional energy yield of 5–15% from ground albedo reflection – particularly valuable in ground-mounted systems and flat-roof installations with light-colored membranes.

30-Year Power Warranty – Above Market Standard

The manufacturer offers a 30-year linear power warranty, whereas the industry standard among many non-top-tier producers typically stands at 25 years. The extended warranty horizon simplifies NPV modeling for PV farm projects and improves bankability with project finance lenders.

132-Cell Format / 750 W – Lower BoS Costs

At 750 Wp per module, fewer panels, mounting hardware, cables, and labor hours are required for the same installed capacity. For systems exceeding 100 kWp, the difference in Balance of System (BoS) costs can reach several percentage points compared to 400–500 Wp modules.

Full IEC and CE Certification Package

The series holds IEC 61215 (mechanical and electrical performance), IEC 61730 (safety), CE, ISO 9001, and ISO 14001 certifications, along with compliance with the European EPR regulation (Germany, France) – eliminating regulatory barriers for EU export and grid interconnection.

Trade-offs
No BNEF Tier-1 Status

Gamko New Energy does not appear on the Bloomberg NEF Tier-1 Solar Module Manufacturers list (Q1 2026). For large-scale PV farm projects financed by banks or infrastructure funds, BNEF Tier-1 status is frequently a formal bankability requirement, which may restrict the series' applicability in projects above 1 MWp with third-party debt financing.

Limited Manufacturing Scale vs. Market Leaders

Gamko's annual production capacity is approximately 1.2 GW (2023), while leading TOPCon manufacturers (Jinko, LONGi, Tongwei) operate at 60–100 GW. The smaller scale introduces risks of supply delays on large orders and reduced negotiating leverage within the component supply chain.

Common questions

6 answered
What warranty does the Gamko New Energy GKA210N132 series carry, and what does it cover?
The GKA210N132 series is covered by a 12-year product warranty against physical defects and material failures, as well as a 30-year linear power output warranty. The power warranty means the manufacturer guarantees that the modules will maintain a specified minimum energy production level for three decades — a critical factor when modeling the return on investment for a utility-scale PV farm or a large commercial installation.
What is TOPCon technology, and why does the GKA210N132 series use it?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that minimizes charge-carrier recombination at the cell surface. In practical terms, this translates to module efficiency of approximately 23%, improved performance at elevated temperatures during summer months, and a lower power degradation under low-irradiance conditions compared with conventional PERC cells — all of which contribute to higher annual energy yield.
Is the GKA210N132 750W panel bifacial, and does that matter for ground-mounted installations?
Yes, the GKA210N132 series is a bifacial module, meaning it generates electricity from both the front and rear faces by capturing albedo radiation reflected from the ground surface. In ground-mounted installations with a light-colored substrate or bright gravel ballast, the rear-side gain can reach 5–15% of additional energy output, improving the farm's economic performance without requiring any additional land area.
Can the Gamko GKA210N132 panels withstand Polish weather conditions, including heavy snow and strong wind?
The GKA210N132 series is certified for a snow load of up to 5,400 Pa and a wind load of up to 2,400 Pa. This means the modules can withstand the deep snow accumulation typical of Polish winters without structural damage. Additional certifications for salt mist and ammonia resistance (issued by TÜV Nord) make the series equally suitable for installations near agricultural areas or coastal environments.
What types of projects and installations are the GKA210N132 730W–750W series best suited for?
With rated power up to 750 W in a 132-cell format, the series is optimally suited for applications where available space is limited but energy demand is high: utility-scale PV farms, manufacturing facilities, warehouses, large agricultural operations, and commercial buildings with high electricity consumption. The high per-module wattage reduces the total number of modules required to reach a target system capacity, which lowers balance-of-system (BoS) costs and shortens installation time.
Is the Gamko GKA210N132 series still available for purchase?
Yes, the GKA210N132 series in the 730W–750W power range is currently available and in continuous production. Gamko New Energy maintains stock in European warehouses, which significantly reduces lead times for order fulfillment. For large B2B projects, however, it is advisable to confirm the availability of the required volume with your distributor in advance to avoid delays in the construction schedule.
