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.

What owners get
N-type TOPCon cell technology

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.

21.5-22.5% module efficiency

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.

30-year linear power warranty

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.

BNEF Tier 1 bankable manufacturer

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.

SMBB multi-busbar interconnect

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.

Trade-offs
Monofacial only - no bifacial SKU

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).

Peak efficiency below Luxor ECO LINE

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.

About the HS 182-108 TC Ocean N-type Mono-facial Modules series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What is TOPCon technology in Horay Solar HS 182-108 TC Ocean panels and why does it matter?
TOPCon (Tunnel Oxide Passivated Contact) is an advanced N-type cell manufacturing process that reduces carrier recombination at the cell surface. In practice it delivers higher efficiency and slower power degradation than older PERC cells. The HS 182-108 TC Ocean series reaches 440 Wp peak power thanks to this technology, making it a solid choice for installations focused on long-term energy yield.
What warranty does Horay Solar provide on the HS 182-108 TC Ocean modules?
Horay Solar offers a 12-year product warranty covering material and workmanship defects, plus a 30-year linear power warranty. The extended linear power guarantee precisely limits annual degradation throughout the module's operational life, enabling more accurate ROI forecasting and long-term yield planning for both residential and commercial installations.
What is the peak power of the Horay Solar HS 182-108 TC Ocean and how many modules does a home system need?
Each module delivers 440 Wp at peak. A 10 kWp residential system requires approximately 23 panels, which fits comfortably on a standard pitched roof. The high per-module wattage lowers the total panel count, simplifies wiring, and reduces overall BoS costs compared to lower-wattage modules of equivalent total system capacity.
Is the Horay Solar HS 182-108 TC Ocean series suitable for sloped roofs and which mounting systems are compatible?
Yes, these modules are designed for compatibility with mainstream aluminum racking systems used on sloped roofs. Horay Solar emphasizes straightforward BoS integration, which shortens installation time and lowers hardware costs. The monofacial design also simplifies system planning since rear-side irradiance does not need to be factored into the yield model.
What does SMBB mean in the HS 182-108 TC Ocean modules and what benefit does it provide?
SMBB (Super Multi Busbar) replaces a few thick busbars with a greater number of thinner ones per cell. The shorter electron path to the busbar reduces resistive losses, and the higher busbar count limits permanent power loss from microcracks, since adjacent busbars take over current collection from any cracked area. The result is more stable long-term energy output.
Do Horay Solar HS 182-108 TC Ocean panels perform well in variable irradiance and low temperatures?
Yes. N-type TOPCon cells have a better temperature coefficient and superior low-light performance compared to P-type PERC cells. This means less power loss on hot days and on overcast days typical of Central European climates. For installations where irradiance is variable and seasonal, this translates into a more predictable and bankable yield across the full 30-year warranty period.
