The Hitouch 6N Pro series delivers advanced Hanersun photovoltaic modules engineered to maximize energy yield in commercial and industrial installations. The use of second-generation N-TOPCon technology combined with 210mm half-cut cells results in higher conversion efficiency while reducing current losses and micro-crack risk. The bifacial design allows additional energy capture from light reflected off the ground, meaningfully boosting output on industrial rooftops, ground-mount arrays, or solar farms without increasing the installed footprint. The panels stand out for their low power degradation - just 1% in the first year and 0.4% annually thereafter - translating into stable, predictable returns throughout the system's lifetime. Optimized cell-level electrical design lowers hot-spot risk, while a reinforced mechanical structure ensures resistance to extreme snow and wind loads, making the series well suited to demanding climate conditions such as those in Poland. The modules are backed by a 30-year linear power warranty and a 15-year product warranty, further secured through Munich RE. Hitouch 6N Pro is the choice for investors and installers seeking high reliability, long-term profitability, and resilience under harsh operating conditions.

What owners get
Low power degradation (0.4%/year)

Second-generation N-TOPCon technology delivers only 1% power loss in year one and 0.4% annually thereafter - notably better than typical PERC modules at 2%/0.55%, resulting in higher cumulative energy yield over a 30-year system lifetime.

30-year linear power warranty

The manufacturer guarantees linear power degradation over 30 years, matching the best-in-class standard offered by leading TOPCon manufacturers, additionally backed by a Munich RE insurance policy that reduces counterparty default risk on the warranty.

Bifacial dual-sided construction

Bifaciality of up to 80-85% (per Hitouch 6N family documentation) enables an additional 10-30% energy gain from ground-reflected light, boosting output for ground-mount and light-colored industrial roof installations without increasing footprint.

High conversion efficiency (up to 24.1%)

Half-cut 210 mm cells with N-TOPCon technology reach up to 24.1% efficiency, placing the series on par with segment competitors such as SunEvo Solar EVO 6N (24.1%) and close to Gamko GKA210N132 (24.14%).

Reinforced mechanical construction

Dual heat-strengthened glass (2×2.0 mm) and a reinforced frame provide resistance to extreme snow and wind loads, relevant for installations in more demanding climates such as Poland.

Trade-offs
No current BNEF Tier 1 status

Hanersun achieved BNEF Tier 1 classification in 2023, but per the provided data the manufacturer does not currently appear on the quarterly Tier 1 list (BNEF publishes and updates this list regularly, e.g. removing JinkoSolar in 2024). Lack of current Tier 1 status may complicate project financing for lenders requiring Tier 1 bankability.

Efficiency slightly below segment leader

Maximum efficiency of 24.1% is marginally lower than Ocean Solar AOX-132G12HC (24.2%), which for large commercial installations can translate into a slightly lower energy yield per unit of surface area.

New series with no long-term track record

The Hitouch 6N Pro series launched in 2026, so - unlike the manufacturer's older, established lines - it lacks multi-year field data confirming the claimed durability and low degradation under real-world operating conditions.

Common questions

6 answered
What is the maximum power output of the Hanersun Hitouch 6N Pro panel?
The Hitouch 6N Pro series reaches up to 750 Wp. This is achieved through second-generation N-TOPCon cells sized 210 mm combined with half-cut technology, which reduces current losses and delivers higher conversion efficiency than standard PERC modules.
How does N-TOPCon technology differ from standard PERC cells?
N-TOPCon is a second-generation technology that increases energy conversion efficiency by reducing carrier recombination on the rear side of the cell. Compared to PERC, it delivers higher rated power, lower degradation over time, and better performance at high temperatures, resulting in greater energy yield from the same roof area.
Do bifacial Hitouch 6N Pro panels really deliver higher energy yield?
Yes, the bifacial design captures additional reflected radiation from the roof, ground, or surrounding surfaces. The actual gain depends on the surrounding albedo and mounting height, but typically ranges from a few to over ten percent more energy than monofacial panels, without increasing the installation footprint.
What warranty applies to Hanersun Hitouch 6N Pro panels?
The manufacturer provides a 15-year product warranty and a 30-year linear power warranty. These warranties are additionally backed by insurer Munich RE, adding extra financial security for the investment even if issues arise with the manufacturer.
Can Hitouch 6N Pro panels withstand heavy wind and snow loads in Poland?
Yes, the series features a reinforced mechanical structure designed for extreme snow and wind loads. This matters in Poland's climate, where heavy winter snowfall is common, and the panels must handle the added load without risk of microcracks or frame damage.
What type of installations are Hitouch 6N Pro panels best suited for?
With high power output (up to 750 Wp), bifacial design, and strong mechanical durability, the series is mainly intended for commercial and industrial installations - large-scale roofs, PV farms, and ground-mount systems where maximizing energy yield at scale is the priority.
