Light for its output, no clear weak spot
The HY SOLAR N-Type TOPCon series (available in various configurations and frame options) is designed for real-world operating conditions, where stable performance, predictability, and energy loss resistance are paramount. A key advantage is the use of N-Type TOPCon cell technology, which supports high efficiency over the long term and helps to minimize performance degradation typical of older solutions. Many variants feature a bifacial design, allowing the module to also utilize reflected light from the ground, which improves energy production in PV farms, ground-mounted systems, and PV+ projects.
The use of SMBB and half-cut cell technology also enhances current flow within the module and improves performance under partial shading. The manufacturer also highlights improved performance in low-light conditions and the beneficial impact of a lower temperature coefficient on energy yield in hot weather. This series is ideal for investors who want to combine high power density with practical reliability in commercial and industrial projects.
Ranking
Signals from the data
Commercial, utility-scale, shaded-installations and hot-climate.
Top 6% of the TOPCon 650-700 W segment, against a median of 53.2. Ranked 1,131st in the whole database.
Peak module efficiency reaches 23.8%, while directly comparable series (Huasun Himalaya V-ocean, Phono Solar Monocrystalline132, Recom Lynx) top out at 23.5%. The 0.3 percentage-point advantage translates into higher power density for the same roof or ground area.
A temperature coefficient of -0.29%/°C compares favorably to typical PERC modules (-0.34% to -0.37%/°C) and is on par with leading N-type TOPCon products on the market. In real-world conditions where module temperatures can reach 65–70°C during summer, the difference yields measurably higher daily energy output at peak season.
A bifaciality factor of 80–85% enables efficient harvesting of reflected albedo in ground-mounted farms and agrivoltaic systems. On high-albedo surfaces (albedo >20%), installations can expect an additional 5–12% energy yield compared to standard monofacial modules.
The manufacturer guarantees ≥87.40% of rated power output after 30 years, with annual degradation ≤0.4% (≤1% in year one). This aligns with best-in-class TOPCon market standards and gives investors confidence in long-term financial models without applying an accelerated degradation discount.
Availability of 86 power variants ranging from 445 to 730 Wp allows module selection across a wide range of project formats — from BIPV applications and small industrial rooftops to large utility-scale ground-mounted farms — without switching manufacturers within a project portfolio.
HY SOLAR does not appear on the BloombergNEF Tier-1 list (Q1 2026), meaning it lacks confirmed bankability in the context of non-recourse project financing. For bank-financed commercial and industrial projects, this may require additional product insurance or escrow arrangements that Tier-1 manufacturers — such as peer competitor Phono Solar — do not necessitate.
- 23.3% module efficiency - 0.9pp better than the TOPCon 650-700W median of 22.4%
- At 233.2 W/m² power density, this panel generates 9.5 W/m² more per unit area than TOPCon 650-700W median (223.7 W/m²)
- At -0.29%/°C, hot weather performance is typical for TOPCon 650-700W panels
- Weight of 30.6 kg (4.0 kg below TOPCon 650-700W median of 34.6 kg) allows easier transport and roof mounting
- In the top 7% for efficiency among all TOPCon panels
