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. ## Cons - **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 this series 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. ## Notable figures - 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 ## Questions ### 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. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/hs182-108tc-ocean-440w-a7c4765a9d21.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +50 W, cooler, +2.0 pp | | [Suntech STP-NT11/48QGSF-490](https://comparepv.com/panel/suntech-stp-nt11-48qgsf-490) | 490 W | +50 W, cooler, +2.0 pp | | [JA Solar JAT54S40-485/LR](https://comparepv.com/panel/ja-solar-jat54s40-485-lr) | 485 W | +45 W, cooler, +1.8 pp | | [AIKO AIKO-A485-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a485-mce54mw) | 485 W | +45 W, cooler, +1.8 pp | | [AIKO AIKO-A485-MAH54Mw](https://comparepv.com/panel/aiko-aiko-a485-mah54mw) | 485 W | +45 W, cooler, +1.8 pp | | [Gokin GK-5-54HG-485M](https://comparepv.com/panel/gokin-gk-5-54hg-485m) | 485 W | +45 W, cooler, +1.8 pp | | [Heckert Solar ZEUS 3.0+ 108 485WP](https://comparepv.com/panel/heckert-solar-zeus-3-0-108-485wp) | 485 W | +45 W, heavier, +1.8 pp | | [Horay Solar HS420TC-MHO-D](https://comparepv.com/panel/horay-solar-hs420tc-mho-d) | 420 W | -20 W, heavier, -1.0 pp | | [Horay Solar HS425TC-MHO-D](https://comparepv.com/panel/horay-solar-hs425tc-mho-d) | 425 W | -15 W, heavier, -0.7 pp | | [Horay Solar HS430TC-MHO-D](https://comparepv.com/panel/horay-solar-hs430tc-mho-d) | 430 W | -10 W, heavier, -0.5 pp | | [Horay Solar HS435TC-MHO-D](https://comparepv.com/panel/horay-solar-hs435tc-mho-d) | 435 W | Heavier | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +70 W, cooler, +2.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +55 W, cooler, +2.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +65 W, cooler, +2.2 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +65 W, heavier, +2.2 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +60 W, cooler, +2.0 pp | --- Source: https://comparepv.com/panel/horay-solar-hs440tc-mho Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
