Efficiency leader, no clear weak spot
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.
Ranking
Signals from the data
Commercial, utility-scale and hot-climate.
Top 8% of the TOPCon 550-600 W segment, against a median of 22.44%. Ranked 1,911th in the whole database.
Top 11% of the TOPCon 550-600 W segment, against a median of 224.4.
Top 14% of the TOPCon 550-600 W segment, against a median of 53.8.
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 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.
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.
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.
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.
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.
- 23.0% module efficiency - 0.6pp better than the TOPCon 550-600W median of 22.4%
- Power density of 230.2 W/m² packs 5.8 W/m² more into the same footprint vs TOPCon 550-600W median (224.4 W/m²)
- At -0.30%/°C, hot weather performance is typical for TOPCon 550-600W panels
- At 26.7 kg, this panel is 4.5 kg lighter than TOPCon 550-600W median (31.2 kg) - easier handling during installation
- Ranked #1911 out of 14005 panels for efficiency in the database
