The series sits in the top tier of the 182mm/144-cell segment, delivering high energy yield per unit of roof or ground area. - **N-type TOPCon - negligible LID degradation** - N-type TOPCon cells eliminate Light-Induced Degradation (LID), which can cause 1-2% first-year power loss in P-type PERC modules. Zero LID translates into higher actual energy production in early project years and more predictable financial modeling. Additionally, N-type cells exhibit a lower temperature coefficient (typically -0.29 to -0.30%/°C vs. -0.35%/°C for PERC), improving yield during peak summer generation hours. - **Bifaciality >80% - rear-side energy gain** - N-type bifacial construction achieves a bifaciality factor above 80%, versus approximately 70% for P-type bifacial modules. In ground-mount installations with light-colored surfaces (albedo 0.2-0.4), this translates into a real annual production increase of 8-15% over an equivalent monofacial panel rated at the same STC power - a key advantage for utility-scale PV farms and carports. - **30-year linear power warranty** - The manufacturer provides a 30-year linear performance warranty, aligned with N-type TOPCon premium-tier standards and exceeding the 25-year power warranty still common among PERC manufacturers at comparable price points. The product warranty stands at 15 years (above the 12-year segment minimum), and the extended performance guarantee supports project bankability and simplifies LCOE modeling. - **IEC 61701 & IEC 62716 certified - harsh environments** - The Ocean series has passed salt mist corrosion (IEC 61701) and ammonia resistance (IEC 62716) testing, confirming suitability for coastal installations, agricultural rooftops, and industrial C&I sites. This directly addresses requirements for PV farms in climatically demanding regions where standard modules degrade faster due to corrosion of frames and encapsulant layers. ## Cons - **Limited manufacturing scale vs. market leaders** - Horay Solar's annual production capacity of approximately 2.5 GW/year is far below Jinko Solar (>90 GW), JA Solar (~80 GW), and Trina Solar (~77 GW shipments, Wood Mackenzie H1 2025). For utility-scale procurement contracts above 50 MWp, the limited scale may introduce supply continuity risk and longer lead times, requiring earlier volume reservations compared to top-5 manufacturers. - **Lower brand recognition in project finance** - Despite confirmed BNEF Tier 1 status (Q1 2026), Horay Solar does not appear consistently in Wood Mackenzie top-tier rankings or the reference portfolios of major infrastructure lenders as prominently as JA Solar or Trina Solar. In projects requiring project finance or bank guarantees, this may result in a higher manufacturer credit-risk premium or a requirement for additional warranties. ## About this series The Horay Solar HS 182-144 TC-D Ocean series consists of N-type bifacial modules designed for maximum energy yield, where every percentage counts. Thanks to its **bifacial design**, the panel can effectively utilize reflected light from the ground, which significantly improves energy production in ground-mounted, flat roof, and clear-surface installations. The N-type cells are characterized by **low LID degradation**, which ensures stable performance over the long term and provides predictable results. The Ocean series has also been optimized for demanding operating conditions, with the manufacturer highlighting its **resistance to corrosive environments** (sea spray and ammonia) and good performance in low-sunlight conditions. For investors and installers, the **long linear warranty** is also important, supporting the profitability of projects. This is the ideal choice for PV farms, carport structures, and modern C&I installations, where technological advantages are key. ## Notable figures - Efficiency of 22.3% matches the \*\*TOPCon 550-600W\*\* median - Power density of 222.5 W/m² matches the \*\*TOPCon 550-600W\*\* median - Temperature coefficient of -0.28%/°C matches the \*\*TOPCon 550-600W\*\* median - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof - #5161 for efficiency, #1347 for temperature performance out of 14129 panels ## Questions ### What is the warranty on the Horay Solar HS 182-144 TC-D Ocean panels? The HS 182-144 TC-D Ocean series comes with a 15-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. The extended power warranty is especially relevant for utility-scale PV farms and C&I projects, where predictable long-term output directly supports financial modeling and investor confidence. ### What are the real energy gains from the bifacial design of the Horay Solar HS 182-144 TC-D Ocean? The bifacial design lets the rear cell surface capture light reflected off the ground or rooftop surface. In ground-mounted systems with high-albedo substrates (gravel, concrete, snow), the bifacial gain typically ranges from 5-15% over an equivalent monofacial module. The actual yield boost depends on module elevation, row spacing, and substrate albedo - higher clearance and bright ground coverings maximize rear-side irradiance. ### How does TOPCon technology in the Ocean series compare to older PERC cells? TOPCon N-type cells feature a tunnel oxide passivation layer that reduces carrier recombination and enables higher conversion efficiency than PERC. The most tangible practical advantage is very low LID (light-induced degradation) - N-type modules lose significantly less power in the first weeks of operation compared to PERC equivalents. The result is more stable output from day one and better performance over the 30-year warranty period. ### Are the Horay Solar HS 182-144 TC-D Ocean panels suitable for corrosive environments such as coastal sites or poultry farms? Yes, the Ocean series is specifically designed for harsh operating environments. Horay Solar highlights resistance to salt mist and ammonia, indicating compliance with IEC 61701 salt spray testing and equivalent ammonia exposure standards. This makes these modules a practical choice for coastal installations as well as agricultural settings where ammonia vapors can accelerate corrosion of frames and connectors in less robust modules. ### How do the HS 182-144 TC-D Ocean modules perform in low-light and cold-weather conditions? N-type TOPCon cells have a low temperature coefficient of power and better spectral response to diffuse irradiance compared to PERC. This translates to higher energy yield on overcast days and during winter months with low sun elevation angles. The Ocean series is specifically optimized for low-irradiance conditions, with improved efficiency ratings at 200 W/m², making it well-suited for markets with high cloud cover. ### What types of installations are the 590 Wp Horay Solar HS 182-144 TC-D Ocean modules best suited for? At 590 Wp with a 182 mm half-cut 144-cell format, these modules are optimized for commercial and utility-scale applications: ground-mounted PV farms, carports, and large C&I rooftop systems. The high per-module power output reduces total module count and simplifies BoS wiring, while the bifacial design improves LCOE in ground-mounted configurations. For standard residential sloped-roof installs, smaller-format modules in the same TOPCon technology family are generally a better fit. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HS182-144TC-D-Ocean-590W-a7ab081c599d.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.5 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.3 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | -25 W, 15 kg lighter, +2.1 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -35 W, lighter, +2.1 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | -35 W, lighter, +2.1 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | -30 W, lighter, +2.0 pp | | [AIKO AIKO-A625-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a625-mah72dw) | 625 W | +50 W, cooler, +1.9 pp | | [Horay Solar HS570TC-MHO](https://comparepv.com/panel/horay-solar-hs570tc-mho) | 570 W | Lighter | | [Horay Solar HS580TC-MHD-D](https://comparepv.com/panel/horay-solar-hs580tc-mhd-d) | 580 W | +0.3 pp | | [Horay Solar HS585TC-MHO-D](https://comparepv.com/panel/horay-solar-hs585tc-mho-d) | 585 W | +10 W, +0.3 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +75 W, lighter, +2.9 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +70 W, lighter, +2.7 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +65 W, lighter, +2.5 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +60 W, lighter, +2.3 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +55 W, cooler, +2.1 pp | --- Source: https://comparepv.com/panel/horay-solar-hs575tc-mho-d Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
