Strong in heat, no clear weak spot
The Horay Solar HS 182-108 TC Ocean series are N-type monofacial modules designed for real-world conditions in rooftop and commercial installations. The use of TOPCon technology and SMBB (multi-busbar) connections results in more stable energy production over the long term and improved resistance to microcracks and connection losses. This solution is particularly valuable in situations where predictable energy yield is crucial, such as under varying temperatures and uneven solar exposure.
In practice, the HS 182-108 TC Ocean series helps reduce the risk of rapid power degradation and simplifies the maintenance of installation parameters over the years thanks to long linear warranties. The modules are designed for compatibility with mainstream mounting systems and logistics, which shortens implementation times and reduces BOS (Balance of System) costs. This makes it a good choice for EPC (Engineering, Procurement, and Construction) companies, investors in C&I (Commercial and Industrial) projects, and prosumers who expect high efficiency without compromising on quality.
Ranking
Signals from the data
Residential, commercial and shaded-installations.
Top 4% of the TOPCon 400-450 W segment, against a median of -0.290. Ranked 1,347th in the whole database.
Top 8% of the TOPCon 400-450 W segment, against a median of 220.2. Ranked 4,158th in the whole database.
Top 8% of the TOPCon 400-450 W segment, against a median of 51.5. Ranked 1,235th in the whole database.
N-type TOPCon cells exhibit near-zero LID (Light-Induced Degradation) and a lower temperature coefficient (typically ~-0.28%/°C) compared to PERC (-0.35%/°C), delivering measurably higher annual energy yield in rooftop and C&I installations operating at elevated cell temperatures - especially relevant for poorly ventilated rooftops.
The Ocean series efficiency range is directly competitive with leading 182 mm N-type peers: Seraphim Nebula tops at 22.53% and KDM Kingdom Solar at 22.5%, placing the Ocean series in the same performance bracket - well above mainstream PERC (19-21%) and without requiring surface-area compromises in typical rooftop designs.
Horay Solar backs the Ocean series with a 30-year linear performance guarantee (market-standard TOPCon: ≥87% remaining power after 30 years), exceeding the typical 25-year warranty on PERC modules from mainstream manufacturers and directly reducing project LCOE - a strong argument in C&I financial modeling.
Horay Solar has been listed as a BNEF Tier 1 module manufacturer since Q1 2025, reconfirmed in Q1 2026. Tier-1 bankable status enables project financing from institutional lenders, reduces counterparty risk, and simplifies insurance - critical for institutional investors and lease-financed prosumer installations.
The SMBB (Super Multi Busbar) cell interconnection reduces series resistance, limits micro-crack propagation during shipping and installation, and improves shadow-tolerance - all critical reliability factors for rooftop systems subject to uneven irradiance and mechanical stress from chimneys or antenna shadows.
The series offers no bifacial variant: in 2025, bifacial modules hold ~70% market share, and ground-mount systems with high-albedo surfaces capture an additional 5-30% bifacial gain. For utility-scale, carport, or flat-roof projects with light-colored membranes, the absence of a bifacial option represents a quantifiable yield disadvantage versus bifacial N-type TOPCon alternatives (e.g., Seraphim Nebula bifacial).
Direct peer comparison: Luxor Solar ECO LINE N-TYPE TOPCon Non-Reflect reaches 22.86% vs. the Ocean's 22.5% maximum - a 0.36 percentage-point gap translating to ~1.6% less energy per unit roof area. This matters for space-constrained rooftop projects where maximizing W/m² is the primary design constraint.
- At 22.5% efficiency, this panel is on par with typical TOPCon 400-450W modules
- At 225.3 W/m² power density, this panel generates 5.1 W/m² more per unit area than TOPCon 400-450W median (220.2 W/m²)
- At -0.28%/°C, hot weather performance is typical for TOPCon 400-450W panels
- At 20.5 kg, this panel is 1.5 kg lighter than TOPCon 400-450W median (22.0 kg) - easier handling during installation
- Ranked #4281 out of 14129 panels for efficiency in the database
