The SMBB (multi-busbar) design reduces resistive losses and improves tolerance to micro-cracks, enhancing long-term reliability. - **21.9-22.7% efficiency above peer comparables** - The Ocean series reaches 21.9-22.7% efficiency, clearly outperforming two of three direct peers in the segment: DMEGC GHxxxM10T-B66HST (20.9%) and Heliene 144HC M10 SL (20.9%). Higher Wp/m² lowers BoS costs (racking, cabling, land) in C&I and utility-scale PV installations. - **30-year linear power warranty** - The manufacturer guarantees power output for 30 years, exceeding many competitors that offer 25-year power warranties. For projects financed on a non-recourse basis, a longer warranty horizon reduces production risk and can improve project finance terms with lenders. - **BNEF Tier-1 bankability (Q1 2025)** - Horay Solar was included on the BNEF Tier-1 list starting Q1 2025, confirming bankability under the methodology requiring supply to ≥6 10 MW projects financed non-recourse by ≥6 independent banks. This status is a prerequisite for most institutional project financiers and simplifies due diligence for investors. - **Strong low-light performance** - N-type TOPCon modules maintain 80-88% of rated efficiency under overcast conditions (irradiance 200 W/m²), versus 70-75% for standard P-type PERC. In Poland's climate, where a significant share of annual generation occurs during diffuse-light days, this translates into a measurably higher annual energy yield. ## Cons - **Mono-facial only - no bifacial gain** - The Ocean series is a mono-facial module, whereas the direct peer Heliene 144HC M10 SL offers a bifacial version at the same 540 Wp power class, capable of generating an additional 5-25% energy in ground-mount installations with reflective ground cover. In utility-scale PV projects where bifacial is now the de facto standard, the absence of this feature is a significant limitation. - **Efficiency 1.7 pp below segment leader** - Gokin GK-5-60HG achieves 24.4% efficiency at the same 540 Wp power class - approximately 1.7 percentage points above the Horay Ocean maximum of 22.7%. In rooftop C&I installations with limited surface area, this gap directly reduces available peak power for a given footprint. - **12-year product warranty below premium standard** - Leading Tier-1 manufacturers (JA Solar, LONGi, Trina Solar) now offer 15-year product warranties as standard. Horay Ocean's 12-year coverage is below this benchmark, which may represent higher module replacement cost risk during the mid-life phase of a 30-year PV project. ## About this series The Horay Solar HS 182-132 TC Ocean (N-type Mono-facial Modules) series are modules based on N-type technology with an **SMBB (multi-busbar) design**, designed for stable energy production under real-world conditions. A key advantage is **lower power degradation over time**, which translates to more predictable yields and better return on investment throughout the entire lifespan of the installation. In practice, this helps to mitigate the risk of performance losses that often affect standard solutions. Another distinguishing feature of the Ocean series is **excellent performance in low-sunlight conditions** - which is important in Poland, where frequent cloud cover and shorter days can reduce production. The manufacturer also emphasizes **compatibility with mainstream mounting systems** and logistics, which makes it easier to design C&I farms and commercial installations without costly modifications. This is a good choice for C&I installations, PV farms, and projects where long-term reliability and a lower BOS (Balance of System) cost due to high power density are important. ## Notable figures - Efficiency of 22.3% matches the \*\*TOPCon 500-550W\*\* median - 223.2 W/m² power density is 4.2 W/m² below \*\*TOPCon 500-550W\*\* median (227.4 W/m²) - requires larger installation area - At -0.28%/°C, hot weather performance is typical for \*\*TOPCon 500-550W\*\* panels - Weight of 24.5 kg (2.5 kg below \*\*TOPCon 500-550W\*\* median of 27.0 kg) allows easier transport and roof mounting - Ranked #5161 out of 14129 panels for efficiency in the database ## Questions ### What warranty does the Horay Solar HS 182-132 TC Ocean series come with? The HS 182-132 TC Ocean series includes a 12-year product warranty covering material and manufacturing defects, along with a 30-year linear power output warranty. Thanks to N-type TOPCon cell technology, the annual degradation rate is lower than that of standard P-type PERC modules, meaning the panel retains a higher share of its rated power over its lifespan. This is among the longest power warranties currently available in the market. ### How does the Horay Solar Ocean HS 182-132 TC perform in low-light and overcast conditions? The Ocean series is optimized for strong low-light performance, which is especially relevant in climates with frequent cloud cover and short winter days. N-type TOPCon technology offers greater sensitivity to diffuse irradiance compared to PERC modules, allowing the system to generate more energy during dawn, dusk, and overcast hours. This translates into measurably higher annual energy yield in regions with limited peak sun hours. ### What is TOPCon technology and how does it differ from PERC in the Horay Solar Ocean modules? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that uses a thin tunnel oxide layer to suppress carrier recombination at the cell surface. Compared to P-type PERC, TOPCon cells achieve higher conversion efficiency, a lower temperature coefficient (less power loss in heat), and are virtually free of Light-Induced Degradation (LID). For the end user, this means more kilowatt-hours per year and a better LCOE over a 25-30 year project lifetime. ### What is the maximum power output of the Horay Solar HS 182-132 TC Ocean and what applications is it designed for? The module has a maximum rated power of 540 Wp. The HS 182-132 TC Ocean is primarily suited for commercial and industrial (C&I) installations and utility-scale PV farms, where high per-module wattage reduces BoS costs and simplifies logistics. The series is compatible with mainstream racking and mounting systems, making it straightforward to integrate into large-scale projects without costly structural modifications. ### Is the Horay Solar HS 182-132 TC Ocean a bifacial or mono-facial module? The HS 182-132 TC Ocean is a mono-facial module, meaning energy is harvested exclusively from the front side of the panel. Unlike bifacial modules, it does not require a high-albedo ground surface or special mounting clearance to achieve its rated specifications. This makes it a straightforward, cost-effective choice for rooftop and ground-mount installations where rear-side irradiance gain is negligible. ### What is SMBB (multi-busbar) technology in the Ocean panels and does it improve module durability? SMBB (Selective Multi-BusBar) replaces a few wide busbars with many narrow ones, shortening the current path across each cell and reducing resistive losses for higher efficiency. Crucially, if a micro-crack develops in a cell, adjacent busbars take over the current flow, limiting power loss. The result is a module that is more resilient to mechanical stress and maintains stable output throughout the full 30-year warranty period. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/hs182-132tc-ocean-540w-cb2ac39bb45c.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | -20 W, cooler, +2.7 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | -35 W, lighter, +2.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +30 W, cooler, +2.5 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | -25 W, cooler, +2.4 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | -25 W, cooler, +2.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +25 W, cooler, +2.3 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | -40 W, lighter, +2.2 pp | | [Horay Solar HS520TC-MHO](https://comparepv.com/panel/horay-solar-hs520tc-mho) | 520 W | -10 W, -0.4 pp | | [Horay Solar HS525TC-MHO](https://comparepv.com/panel/horay-solar-hs525tc-mho) | 525 W | Very close match | | [Horay Solar HS535TC-MHO](https://comparepv.com/panel/horay-solar-hs535tc-mho) | 535 W | Very close match | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +60 W, heavier, +1.5 pp | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +55 W, heavier, +1.3 pp | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +50 W, heavier, +1.2 pp | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +50 W, heavier, +1.1 pp | --- Source: https://comparepv.com/panel/horay-solar-hs530tc-mho Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
