- Efficiency of 22.7% matches the HJT 700-750W median
- Power density of 226.9 W/m² is 3.2 W/m² below HJT 700-750W median (230.2 W/m²) - needs more roof space
- Temperature coefficient of -0.24%/°C matches the HJT 700-750W median
- Bifacial design (90% factor) captures reflected light - adds 4-14% yield on ground-mount or white roof
- In the top 22% for efficiency among all HJT panels

Series GCL-NH12/66GDF 7 variants
The GCL-NH12/66GDF series utilizes advanced n-type TOPCon cell technology, which effectively eliminates the problem of light-induced degradation, translating into stable energy production for decades. Thanks to the bifacial dual-glass design, these modules also absorb radiation from the rear side, significantly increasing total energy yield, especially on surfaces with high albedo. This solution is a direct response to the needs of investors seeking maximum power density while maintaining the highest mechanical durability. The use of SMBB technology improves current flow and minimizes resistance losses, distinguishing this model from standard market solutions. These panels are primarily dedicated to large-scale photovoltaic farms and industrial installations where the lowest levelized cost of energy (LCOE) matters. The robust construction resistant to extreme weather conditions makes this series perform excellently in harsh environments, reducing the risk of micro-cracks. By choosing these modules, you gain the assurance of operation based on a high bifaciality factor, making them one of the most cost-effective options in the premium segment for the professional energy sector.
