Strong in heat, no clear weak spot
The Horay Solar HS 182-120 TC Ocean N-type Mono-facial series consists of N-type solar panels designed for high operational stability and predictable energy yields over the long term. A key feature is the SMBB half-cut technology, which improves current collection on the panel surface and reduces thermal losses - particularly important under high solar irradiance and in systems with high current loads. The use of N-type panels results in very low LID, which helps maintain actual energy production closer to design values, rather than losing it at the start of operation. The modules also offer high performance in low light conditions, making them well-suited for early morning, evening, and cloudy conditions - which are particularly important in Poland. Another advantage is resistance to harsh conditions (including corrosive environments), which makes them suitable for coastal, industrial, and agricultural installations. This makes them a good choice for commercial and industrial (C&I) and photovoltaic (PV) farm investors who prioritize stable energy production and reduced degradation risk.
Ranking
Signals from the data
Commercial and shaded-installations.
Top 12% of the TOPCon 450-500 W segment, against a median of -0.290.
N-type TOPCon cells exhibit light-induced degradation (LID) below 1%, compared to 1.5-3% typical for P-type PERC modules. This translates into measurably higher energy yield in the early years of operation and a more stable production profile across the full 30-year performance warranty period.
The manufacturer provides a 30-year linear performance warranty - on par with best-in-class offerings such as Jinko Tiger Neo and JA Solar Deep Blue 4.0 Pro, and exceeding the historical 25-year market standard. For C&I projects and utility-scale PV farms with bank financing, the extended warranty horizon directly improves LCOE models and bankability assessments during technical due diligence.
The Super Multi-Busbar (SMBB) design combined with a 120-cell half-cut layout shortens the current path and reduces resistive Joule losses versus standard 5 BB configurations. Halving each cell also cuts the working current per section by 50%, reducing thermal stress and improving tolerance to partial shading.
Horay Solar is listed on the BNEF Tier-1 bankable manufacturers list with confirmed Q1 2026 status (~2.5 GW annual capacity, manufacturing in China and Malaysia). For commercially financed projects, Tier-1 status is a practical prerequisite for module acceptance by independent engineers (IE) and lending institutions.
The series has passed salt spray and ammonia corrosion testing (IEC, TUV Rheinland, Lloyd's certifications confirmed), enabling deployment in coastal, agricultural, and industrial installations without additional site restrictions. Mechanical ratings include wind load up to 2,400 Pa and snow load up to 5,400 Pa.
The product warranty covers only 12 years, while competing premium series in the same power class - LONGi Hi-MO X6 (25 years) and JA Solar Deep Blue 4.0 Pro (25 years) - offer more than twice the product coverage. For projects with a 20-25-year lifecycle, this means structural defects (frame, junction box, laminate) occurring after year 12 fall outside the manufacturer's product warranty.
The series is strictly monofacial (is_bifacial: false), entirely excluding energy yield from reflected albedo radiation. The direct peer comparable - DAH Solar DHN-60X16/DG 475-490W - is a bifacial TOPCon N-type module with identical 490 Wp maximum power and 22.71% efficiency, capable of delivering an additional 5-25% energy yield on ground-mounted installations depending on ground albedo.
Maximum module efficiency tops out at 22.6% (490 Wp variant), while direct peer comparables - Renesola RS4-470~490NX-E1 and DAH Solar DHN-60X16/DG - reach 22.71%, and Solar-Fabrik Mono S4 Halfcut BC White achieves 24.0%. Lower-power variants (470 Wp) are rated at only 21.7%, translating to reduced maximum system output for any given roof or land area.
- At 22.2% efficiency, this panel is on par with typical TOPCon 450-500W modules
- 221.7 W/m² power density is 3.5 W/m² below TOPCon 450-500W median (225.2 W/m²) - requires larger installation area
- At -0.28%/°C, hot weather performance is typical for TOPCon 450-500W panels
- Weight of 23.0 kg is typical for TOPCon 450-500W panels
- #5881 for efficiency, #1347 for temperature performance out of 14129 panels
