Efficiency leader, no clear weak spot
The Gamko New Energy GKA210M photovoltaic panel series is based on the use of innovative, large-format silicon cells that redefine the efficiency of modern energy systems. The application of multi-busbar (MBB) technology in combination with half-cut cell architecture allows for the effective minimization of resistive losses and a significant improvement in current flow. This solution directly translates into higher module efficiency even on cloudy days or at high operating temperatures. Investors opting for this series primarily gain lower BOS system costs, as generating more power from a single module drastically reduces the number of mounting elements and cabling needed. The GKA210M series was designed with demanding commercial installations and solar farms in mind, offering the lowest levelized cost of energy (LCOE) in the long-term perspective. It is distinguished from the competition by its exceptional mechanical resistance to wind pressure and snow load, confirmed by rigorous quality tests. This is the ideal choice for entities looking for uncompromising energy stability and maximum utilization of available ground or roof space. A special anti-reflective coating with low dirt accumulation ensures that the panels maintain high productivity without the need for frequent maintenance.
Ranking

Commercial and shaded-installations.
Top 1% of the TOPCon 350-400 W segment, against a median of 18.20%. Ranked 1,919th in the whole database.
Top 1% of the TOPCon 350-400 W segment, against a median of 68.9. Ranked 574th in the whole database.
Top 6% of the TOPCon 350-400 W segment, against a median of 181.8. Ranked 10,584th in the whole database.
The module's rated efficiency of 23% (up to 23.18% per ENF Solar) clearly outperforms all listed competitors: Meyer Burger White at 21.7% (+1.3 pp), Solaria PowerXT at 20.2% (+2.8 pp), and DMEGC GH400M10T-B48HST at 15.48% (+7.5 pp). Higher power density translates to fewer modules per MW of installed capacity and lower BoS costs.
Bifacial cells enable additional energy yield of 10–20% depending on ground albedo and mounting angle. Multi-busbar technology combined with half-cut cell architecture reduces resistive losses and mitigates the impact of partial shading, which is particularly valuable in commercial rooftop and ground-mounted utility-scale installations.
The series carries IEC 61215, IEC 61730, CE-LVD, CE-EMC, ISO 9001, and ISO 14001 certifications. The manufacturer offers a 30-year linear power warranty — matching Meyer Burger White and exceeding the standard 25-year warranty offered by most Tier-1 suppliers such as JA Solar and Trina Solar.
Modules are certified for snow loads up to 5400 Pa and wind loads up to 2400 Pa, meeting the requirements for installations in climatic zones with heavy snowfall. These values comply with IEC standards and are essential for industrial installations in demanding northern European environments.
Certified resistance to salt mist and ammonia enables deployment in harsh industrial environments — including agricultural facilities and coastal sites — without risk of accelerated corrosion of connectors and frames, directly supporting product durability over the 30-year warranty horizon.
Gamko New Energy does not appear on publicly available BNEF Tier 1 bankable manufacturer lists (Q1 2026). The absence of this designation may present a barrier to financing large-scale projects (>10 MW) through independent commercial banks and complicate the procurement of project finance in European markets.
Gamko's annual production capacity is approximately 1.2 GW (2023), whereas Tier-1 market leaders — LONGi, JA Solar, and Trina Solar — operate at 50–100 GW per year. The smaller scale may result in higher unit pricing for large orders, limited service availability, and elevated supply continuity risk over the 30-year warranty period.
- Efficiency of 23.0% is 7.0pp above the TOPCon 0-400W median (16.0%)
- Power density of 207.6 W/m² packs 47.8 W/m² more into the same footprint vs TOPCon 0-400W median (159.8 W/m²)
- At 17.1 kg, this panel is 6.4 kg lighter than TOPCon 0-400W median (23.5 kg) - easier handling during installation
- #1919 for efficiency, #13924 for temperature performance out of 14005 panels
