Strong in heat, no clear weak spot
The Hitouch 5N series from Hanersun represents a new generation of modules built on N-TOPCon cells, engineered for investors who expect high system output even under challenging irradiance conditions. A defining feature of this line is MBB (Multi Busbar) technology, which improves current collection and lowers series resistance, resulting in more stable panel performance throughout its operating life. The use of larger wafers combined with a half-cut cell structure raises conversion efficiency while reducing the risk of hot spots and microcracks, thanks to lower operating current and an optimized cell electrical layout. The panels stand out for their near-zero LID/LeTID effect, meaning minimal power degradation from the very first months of operation, while available bifacial variants further boost energy yield by capturing reflected light on the rear side of the module. The frame and structure are reinforced for resistance to extreme wind and snow loads, making the series a solid choice for both rooftop installations and ground-mounted solar farms in demanding climates. With strong anti-PID performance and a long, linear power warranty, Hitouch 5N is built for those seeking low LCOE and predictable system performance over many years.
Ranking
Signals from the data
Utility-scale, commercial and shaded-installations.
Top 4% of the TOPCon 550-600 W segment, against a median of -0.290. Ranked 1,309th in the whole database.
Top 7% of the TOPCon 550-600 W segment, against a median of 224.4. Ranked 1,758th in the whole database.
Top 10% of the TOPCon 550-600 W segment, against a median of 22.44%. Ranked 1,919th in the whole database.
Efficiency up to 23.2% matches leading N-type modules on the market (e.g., Tongwei TWMND 72HD at 23.2%) and clearly outperforms the competing Talesun BISTAR TP7F78M series (21.5%), yielding higher energy output per roof area.
The Multi Busbar grid improves current collection and lowers series resistance, resulting in more stable module operation and reduced power losses over time compared to older, lower-busbar-count cell structures.
N-type cells virtually eliminate the LID/LeTID effect typical of older P-type/PERC technology, delivering higher real-world energy yield from the very first months of operation and translating into a lower LCOE over the system's lifetime.
The 30-year power warranty matches the standard currently offered by leading N-type manufacturers (including Tongwei and Talesun) and exceeds the typical 25-year power warranties that were common in P-type modules just a few years ago.
35 variants spanning 420–600 Wp allow the series to be matched to both small rooftop installations and large ground-mount farms without switching suppliers across project types.
Hanersun was awarded Tier 1 status by BNEF in Q2 2023, but the BNEF list is refreshed quarterly based on ongoing bank-financed shipments to projects above 10 MW — the manufacturer's current bankability standing is less established than longer-tenured Tier-1 players, and institutional investors should verify it before financing a project.
Product warranty ranges from 15 to 25 years depending on the variant, while the power warranty is fixed at 30 years across the series — meaning lower-cost variants may carry noticeably shorter coverage for material and workmanship defects than the line's premium variants.
- Efficiency of 23.0% is 0.6pp above the TOPCon 550-600W median (22.4%)
- 230.3 W/m² power density - 5.9 W/m² more than TOPCon 550-600W median (224.4 W/m²), more power per roof area
- Temperature coefficient of -0.28%/°C matches the TOPCon 550-600W median
- 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces
- #1919 for efficiency, #1309 for temperature performance out of 14005 panels
