Strong in heat, no clear weak spot
The Huayao TCL Solar Half Cut N-type Bifacial Double Glass Module (G10L-72P) series are modules designed for maximum performance under real-world conditions - not just in a laboratory. The use of N-type solar cells in TOPCon technology minimizes typical power losses associated with LID degradation and helps maintain stable energy production over the years. The bifacial design allows for the recovery of additional light from the rear side, which translates to better performance, especially on bright roofs, ground-mounted structures, and with appropriate substrates.
A key advantage of this series is double glass, which increases resistance to moisture, microcracks, and weather-related stresses - this is particularly important in the Polish climate, where snow, wind, and frequent temperature changes are factors. The half cut design improves performance under partial shading and reduces the risk of hot spots, making the installation more predictable.
This is a good choice for investors in PV farms, commercial roofs, and demanding projects where durability, safety, and high energy yield are important.
Ranking
Signals from the data
Commercial, utility-scale and shaded-installations.
Top 7% of the TOPCon 600-650 W segment, against a median of -0.290. Ranked 1,347th in the whole database.
Top 21% of the TOPCon 600-650 W segment, against a median of 227.7.
Top 23% of the TOPCon 600-650 W segment, against a median of 22.80%.
The G10L-72P series reaches up to 23.4% module efficiency, nearly on par with the GCL SIROT NT10/72GDF (23.42%), and significantly above JS Solar JS210MHC120 (21.4%) and LEDVANCE M585~605P60UB-SF-F3 (21.37%) at the same 605 Wp peak power. This directly translates into more kWh per m² of roof or ground area.
The series carries a 15-year product and workmanship warranty, compared to only 12 years for the direct peer GCL SIROT NT10/72GDF. The extended coverage reduces O&M risk and compresses the discount rate when modeling LCOE for commercial projects.
N-type TOPCon cells eliminate the LID losses typical of PERC. The industry-standard TOPCon degradation curve guarantees ≤1% first-year loss and ≤0.4%/year for years 2-30, ensuring ≥87.4% of nominal power after 30 years - in line with GCL and Trina Solar offerings at this module class.
A glass-glass encapsulation improves resistance to moisture ingress, micro-cracks, and cyclic snow loads - critical for the Polish climate. The bifacial design captures rear-side irradiance: ground-mount installations on high-albedo surfaces typically yield 5-15% additional annual energy output at no incremental module cost.
Splitting cells in half reduces series resistance by roughly 50% and limits hotspot formation under partial shading. The series maintains predictable output on commercial rooftops with obstacles (chimneys, antennas, skylights), which is important for projects with non-uniform shading profiles.
Manufacturer Huayao does not appear on the BNEF Tier 1 module list as of Q1 2026 - having been present in Q1 2025, the company lost its bankable status after BNEF raised the eligibility threshold to projects of at least 10 MW financed by independent commercial banks. The absence of Tier 1 / bankable status may complicate project-finance arrangements for utility-scale PV assets above 1 MW and increase risk premiums in insurance and leasing structures.
- Efficiency of 23.2% matches the TOPCon 600-650W median
- At 232.3 W/m² power density, this panel generates 4.6 W/m² more per unit area than TOPCon 600-650W median (227.7 W/m²)
- Temperature coefficient of -0.28%/°C matches the TOPCon 600-650W median
- Weight of 30.6 kg (2.2 kg below TOPCon 600-650W median of 32.8 kg) allows easier transport and roof mounting
- Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof
