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. - **30-year linear power warranty** - 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. - **SMBB half-cut technology (120 cells)** - 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. - **BNEF Tier-1 bankable status (Q1 2026)** - 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. - **Resistance to harsh environments** - 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. ## Cons - **12-year product warranty** - 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. - **Monofacial design - no bifacial gain on farms** - 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. - **Efficiency below segment leaders** - 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. ## About this series 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. ## Notable figures - 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 ## Questions ### What is the warranty on Horay Solar HS 182-120 TC Ocean N-type modules? The HS 182-120 TC Ocean series comes with a 12-year product warranty and a 30-year linear power output warranty. After 30 years of operation, the module is guaranteed to retain at least 87.4% of its rated power. This is among the longer power warranties available on the market, made possible by the N-type TOPCon cell technology with its very low annual degradation rate and minimal LID effect. ### What is the peak power of the Horay Solar HS 182-120 TC Ocean module and who is it designed for? The HS 182-120 TC Ocean module has a peak output of 490 Wp under standard test conditions (STC), with cell efficiency around 22.6%. The series is aimed primarily at commercial and industrial (C&I) investors and utility-scale PV farms that require a stable production profile, low degradation, and a predictable return on investment. The high per-module wattage also helps reduce the total number of modules needed and lower overall BoS costs. ### What is SMBB half-cut technology in the Horay Solar HS 182-120 TC Ocean panels and is it worth it? SMBB, or Super Multi Busbar, replaces conventional wide busbars with a fine wire mesh, shortening the current path across the cell surface. Half-cut technology splits each cell in half, reducing resistive and thermal losses. In the HS 182-120 TC Ocean modules, combining both technologies results in higher energy yield, better tolerance for micro-cracks, and more stable output under strong irradiance - translating to more kilowatt-hours over the full system lifetime. ### How do Horay Solar HS 182-120 TC Ocean panels perform in overcast or low-light conditions? The N-type TOPCon cells in the HS 182-120 TC Ocean series offer higher sensitivity to diffuse irradiance than standard PERC modules. In climates where overcast skies are frequent - especially in spring and fall - this means measurably more kilowatt-hours per year in real-world conditions. The modules perform noticeably better in the early morning, late afternoon, and on cloudy days, which is a key factor when modeling energy yield and calculating project LCOE. ### Is the Horay Solar HS 182-120 TC Ocean series a bifacial module? No, the HS 182-120 TC Ocean is a mono-facial module - it captures solar energy from the front side only. This simplifies installation, as there is no need to account for ground albedo or elevated mounting structures. For rooftop and C&I applications where ground reflectivity is not a factor, this is a practical choice with lower overall BoS costs compared to bifacial variants. ### Are Horay Solar HS 182-120 TC Ocean panels suitable for coastal, industrial, and agricultural installations? Yes, the Ocean series name reflects a design intent: the HS 182-120 TC modules are built for environments with elevated corrosivity. They meet IEC standards and carry TUV certification confirming resistance to salt mist, high humidity, and aggressive industrial air. This makes them a strong choice for coastal PV farms, industrial rooftops, and agrivoltaic projects where standard modules tend to degrade faster due to harsh environmental conditions. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/hs182-120tc-ocean-490w-c18b31a44276.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +30 W, cooler, +2.8 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | Cooler, lighter, +2.6 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +25 W, cooler, +2.5 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +25 W, cooler, +2.5 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | Cooler, lighter, +2.3 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +20 W, cooler, +2.3 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +20 W, cooler, +2.3 pp | | [Horay Solar HS470TC-MHO](https://comparepv.com/panel/horay-solar-hs470tc-mho) | 470 W | -10 W, -0.5 pp | | [Horay Solar HS475TC-MHO](https://comparepv.com/panel/horay-solar-hs475tc-mho) | 475 W | -0.3 pp | | [Horay Solar HS485TC-MHO](https://comparepv.com/panel/horay-solar-hs485tc-mho) | 485 W | Very close match | | [Horay Solar HS490TC-MHO](https://comparepv.com/panel/horay-solar-hs490tc-mho) | 490 W | +10 W, +0.4 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | +80 W, cooler, +2.6 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | +75 W, cooler, +2.4 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | +70 W, lighter, +2.2 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | +60 W, cooler, +2.2 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | +60 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/horay-solar-hs480c-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.
