Middle of its segment, heavy for its output
The Hanersun HiTouch 6N series features advanced photovoltaic modules based on modern N-type TOPCon cell technology, which sets new standards for the efficiency and durability of solar systems. Thanks to the use of SMBB technology and high-density cells, these panels effectively minimize resistive losses and optimize electrical charge flow, resulting in stable energy production even under low sunlight conditions. A key benefit for the investor is minimal light-induced degradation (LID), which, combined with the limited aging process of materials, guarantees a significantly higher energy yield in the long-term perspective. The HiTouch 6N series solves the problem of limited mounting space by offering maximum power density per square meter, making it an ideal choice for both aesthetic home installations and demanding commercial projects. What distinguishes these modules from standard market solutions is, above all, an excellent temperature coefficient, which ensures high operating efficiency even during summer heatwaves. By choosing the Hanersun HiTouch 6N series, users receive a product that combines innovation with real savings, directly leading to a shorter return on investment period while maintaining the highest safety standards and technical reliability of the components.
Ranking
Signals from the data
Commercial, utility-scale and hot-climate.
Weight-limited structures, roofs where every square metre has to count and hot climates.
Bottom 1% of the TOPCon 700-750 W segment, against a median of 52.9. Ranked 9,733rd in the whole database.
Bottom 7% of the TOPCon 700-750 W segment, against a median of 230.2. Ranked 3,989th in the whole database.
Bottom 8% of the TOPCon 700-750 W segment, against a median of -0.290. Ranked 8,005th in the whole database.
N-type TOPCon cells exhibit LID/LeTID degradation below 1% (confirmed by Kiwa PVEL), with a typical temperature coefficient of -0.29%/°C versus -0.35%/°C for legacy PERC technology. This translates into measurably higher annual energy yield in the Polish climate, where module temperatures regularly exceed 50°C during summer months.
The peak efficiency of 22.7% matches the best modules among direct peer comparables (Renesola RS9-685~705NG-E1 and LEDVANCE M685~705N66UB-SF-F7), confirming that the series is fully competitive with its closest rivals in terms of power density per m².
Hanersun achieved Top Performer status in the 11th edition of the Kiwa PVEL PV Module Reliability Scorecard (2025), confirming that the modules passed rigorous reliability testing (TC, DH, MSS, PID degradation <2%, LID+LeTID <1%). This is one of the most widely recognized independent certifications in the PV industry.
Select variants in the series carry a 30-year linear power warranty, compared to the industry-standard 25 years. The extended warranty horizon directly lengthens the insurable payback period (LCOE), which is a meaningful advantage when structuring project financing.
The availability of 27 variants spanning 605–705 Wp allows precise module selection matched to roof area and target system capacity, minimizing yield losses attributable to geometric constraints or inverter MPPT limitations.
The HiTouch 6N series is available exclusively in a monofacial configuration (is_bifacial: false), whereas the same power class (600–700 Wp) includes bifacial TOPCon modules capable of generating 5–15% additional energy from ground albedo. Hanersun does offer bifacial variants in other series, meaning that choosing the HiTouch 6N means foregoing that generation potential.
The product warranty ranges from 12 to 15 years depending on the variant. Variants at the lower bound of 12 years fall below the current market standard of 15 years, which may be material when assessing risk for bank-financed or leased installations with terms exceeding 12 years.
The available data (tier_1_bankable: false) indicates that the series is not classified as Tier-1 bankable, despite Hanersun having announced BNEF Tier 1 status in 2023. This inconsistency may create friction when securing third-party financing for commercial projects from lenders that require formal bankability classification.
- Efficiency of 22.5% matches the TOPCon 700-750W median
- Power density of 225.3 W/m² is 4.9 W/m² below TOPCon 700-750W median (230.2 W/m²) - needs more roof space
- Temperature coefficient of -0.31%/°C is 0.02pp worse than TOPCon 700-750W median (-0.29%/°C) - higher losses in summer heat
- 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces
- #3982 for efficiency, #8005 for temperature performance out of 14005 panels
