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.

What owners get
N-type TOPCon – Lower LID and Better Performance in Heat

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.

Up to 22.7% Efficiency – On Par with Segment Leaders

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.

Kiwa PVEL 2025 Top Performer – Independent Validation

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.

Up to 30-Year Linear Power Warranty

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.

Wide Configuration Range – 27 Variants, 605–705 Wp

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.

Trade-offs
Monofacial Only – No Bifacial Option

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.

Product Warranty as Low as 12 Years on Some Variants

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.

No Confirmed Tier-1 Bankability Status

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.

Common questions

6 answered
What is TOPCon technology and how does the Hanersun HiTouch 6N series stand out because of it?
TOPCon (Tunnel Oxide Passivated Contact) is an advanced N-type cell architecture featuring an additional passivation layer that reduces carrier recombination. The HiTouch 6N series combines TOPCon with multi-busbar SMBB technology and high-density cells, delivering up to 705 Wp and approximately 22.7% module efficiency. The result is noticeably higher energy yield compared to older PERC cells, especially under low irradiance and overcast conditions.
What warranty does the Hanersun HiTouch 6N panel come with and what does it cover?
The HiTouch 6N series includes a 15-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. The manufacturer guarantees a defined minimum percentage of rated power over three decades of operation. These are premium-tier warranty terms — keep your proof of purchase and warranty card to support any future claims.
Is the Hanersun HiTouch 6N 705 Wp panel bifacial?
No, the 705 Wp HiTouch 6N is a monofacial module — it collects energy from the front side only. Hanersun offers bifacial variants within its broader lineup (models with the HT suffix), but the 705 Wp configuration with an opaque backsheet is designed for standard rooftop installations where albedo gain from the ground surface is not a primary energy-yield driver.
How does the Hanersun HiTouch 6N perform during summer heat waves?
N-type TOPCon cells in the HiTouch 6N series deliver a temperature coefficient of Pmax of approximately –0.31%/°C, which is better than typical PERC modules (around –0.35%/°C). This translates to lower power loss when the module heats up — at 70°C cell temperature, output degradation is noticeably smaller than with older-generation technology, meaningfully improving annual energy yield in Central European climates.
Is the Hanersun HiTouch 6N series suitable for a sloped residential rooftop installation?
Yes, HiTouch 6N panels are well-suited for sloped residential rooftops. The high unit output (705 Wp) lets you achieve the required system capacity with fewer modules, which is a significant advantage on roofs with limited available area. The modules are compatible with standard aluminum-rail racking systems and roof-hook mounting hardware, and their structural ratings meet the wind and snow load requirements typical of the Polish climate.
Is Hanersun a Tier 1 manufacturer and does it matter when financing a solar installation?
Hanersun is not currently listed as a Tier 1 manufacturer under the Bloomberg NEF classification. In practice, some banks and leasing providers may require additional due diligence when financing systems built with modules from non-Tier 1 manufacturers. It is advisable to verify this with your installer or financial advisor before signing a loan or lease agreement to avoid unexpected complications during the approval process.
