The GKA-PRO solar panel series is an advanced solution based on N-type TOPCon technology, which redefines efficiency standards in challenging lighting conditions. Thanks to the use of N-type cells, these modules are characterized by significantly lower light-induced degradation and a better temperature coefficient, which translates into stable energy production even during hot days. The bifacial design used in this series allows for additional energy yield from reflected light reaching the back of the module, making them an ideal choice for ground-mounted installations and commercial carports. An innovative approach to production processes eliminates the PID effect problem, ensuring maximum system lifespan for decades. The GKA-PRO series solves the problem of limited installation space by offering high power density per square meter, allowing for a faster return on investment while maintaining the highest safety standards. Compared to the competition, these panels stand out with an excellent balance between advanced technology and mechanical reliability, confirmed by high resistance to loads from snow and wind. This is an uncompromising choice for investors seeking modern components for building efficient and durable solar power plants that maintain their technical parameters over a long-term horizon.

What owners get
Up to 24.06% Efficiency - Ahead of the Competition

The series' peak module efficiency of 24.06% clearly outpaces its direct competitors: Astronergy ASTRO N5 Bifacial reaches 23.3% and Trina Solar Vertex N reaches 23.0%. In practical terms, this translates to approximately 3-4% more energy yield from the same roof or ground area.

N-Type TOPCon + Bifacial - A Dual Advantage

N-type TOPCon cells exhibit a significantly lower light-induced degradation rate (LID <0.5% vs. ~1-2% for PERC) and a more favorable power temperature coefficient, reducing output losses on hot days. The bifacial construction further increases annual energy yield by 5-15% in ground-mounted systems or installations over high-reflectivity surfaces such as gravel or concrete, assuming a typical albedo of 0.2-0.3.

30-Year Linear Power Output Warranty

The manufacturer provides a 30-year performance warranty, matching the standard set by direct peer comparables Astronergy and Trina Solar. This extended coverage horizon reduces investment risk and facilitates project finance approvals.

Wide Power Range: 20 Variants from 460 to 650 Wp

With 20 wattage configurations within a single series, the lineup allows precise module selection to suit any project scale - from small prosumer rooftop systems to large utility-scale ground-mounted farms - eliminating the need to mix series and simplifying procurement logistics.

Trade-offs
Not Listed on the BNEF Tier 1 Index

Gamko New Energy (annual manufacturing capacity ~1.2 GW as of 2023 data) does not appear on any publicly available BloombergNEF Tier 1 module manufacturer list, unlike Astronergy and Trina Solar. This may present a barrier to securing project finance from lenders and insurance coverage from underwriters that require Tier 1-listed components.

12-Year Product Warranty

Leading Tier 1 manufacturers - including Jinko Solar and LONGi - have moved to a 15-year product warranty. Gamko's standard 12-year coverage means that over a 30-year investment horizon, the final 18 years fall outside full factory protection against workmanship and materials defects.

About the GKA-PRO series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What warranty applies to Gamko New Energy GKA-PRO panels and what does it cover exactly?
The GKA-PRO series comes with a 12-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. This means the manufacturer guarantees a specified minimum energy yield over three decades. Such an extended power warranty is made possible by N-type TOPCon technology, which exhibits exceptionally low annual degradation compared to older P-type cells.
What does it mean that the GKA-PRO panel is bifacial, and does it genuinely produce more energy?
Bifacial means the module's rear glass also transmits light, allowing the cells to generate current from irradiance reflected off the ground surface. In ground-mounted installations over light-colored soil, gravel, or snow, the rear-side energy gain can add an extra 5-15% relative to a monofacial module. In practice, this translates into a measurably lower levelized cost of energy (LCOE) per installed kilowatt.
Are the GKA-PRO 650 W panels suitable for ground-mounted installations in Poland?
Yes, GKA-PRO modules rated up to 650 W are particularly well suited for ground-mounted and commercial installations. The bifacial design maximizes yield from reflected irradiance, while the certified mechanical load ratings - 5,400 Pa snow load and 2,400 Pa wind load - meet Polish building code requirements. The high per-module power rating also reduces the total number of modules required to reach a target farm capacity.
How does the TOPCon technology in the GKA-PRO series differ from mainstream PERC panels?
N-type TOPCon cells incorporate an additional ultra-thin tunneling silicon oxide layer that suppresses charge-carrier recombination. The result is higher efficiency (up to approximately 23%), an improved temperature coefficient, and significantly lower light-induced degradation (LID). During hot Polish summers, a TOPCon panel loses less power output than a comparable PERC module, which directly increases annual energy production.
Is Gamko New Energy a reliable manufacturer, and where are GKA-PRO panels produced?
Gamko New Energy (Nantong Gamko New Energy Co., Ltd.) is a Chinese photovoltaic module manufacturer holding IEC 61215, IEC 61730, ISO 9001, and ISO 14001 certifications, as well as CE marking. The production facility is located in China. Modules undergo a three-stage quality control process including electroluminescence (EL) imaging and flash testing, minimizing the risk of hidden cell microcracks prior to shipment.
How does the GKA-PRO panel perform under low-irradiance conditions, such as overcast days?
N-type TOPCon technology delivers superior low-light performance compared to P-type PERC cells. This means that on overcast days or during the early morning and late evening hours, a GKA-PRO module generates proportionally more energy than lower-cost alternatives. Given Poland's climate, which features a high number of days with diffuse irradiance, this characteristic has a direct and measurable impact on annual energy output.
