Ranked 1,347th in the whole database. - **22.80% module efficiency** - Top 22% of the TOPCon 550-600 W segment, against a median of 22.44%. - **Best for:** Commercial, utility-scale, shaded-installations and hot-climate. ## Specification ### Electrical - **Rated power (Pmax):** 590 W - **Efficiency:** 22.80 % - **Voltage at Pmax (Vmp):** 43.44 V - **Current at Pmax (Imp):** 13.59 A - **Open-circuit voltage (Voc):** 51.63 V - **Short-circuit current (Isc):** 14.38 A - **Max system voltage:** 1500 V ### Temperature - **Temperature coefficient of Pmax:** -0.280 %/degC - **Temperature coefficient of Voc:** -0.230 %/degC - **Temperature coefficient of Isc:** 0.040 %/degC - **NOCT:** 45 degC ### Cell and construction - **Cell type:** Monocrystalline - **Cell technology:** TOPCon - **Cell count:** 144 ### Physical - **Length:** 2279 mm - **Width:** 1134 mm - **Thickness:** 30 mm - **Weight:** 26.0 kg - **Area:** 2.58 m2 - **Power density:** 228.3 Wp/m2 ### Warranty and degradation - **Product warranty:** 12 years - **Performance warranty:** 30 years - **Output guaranteed at end of warranty:** 87.4 % - **First-year degradation:** 1.00 % - **Output after 30 years:** 516 W ## Rank in the whole catalogue | Measure | Position | | --- | --- | | Efficiency | 2769 of 14129 | | Power density | 2786 of 14129 | | Temperature coefficient | 1347 of 14129 | | Weight | 374 of 14129 | | Warranty | 21 of 14129 | ## Pros - **N-type TOPCon - low Tc and degradation** - N-type TOPCon cells deliver a temperature coefficient for Pmax of approximately -0.29 to -0.31%/°C versus -0.35 to -0.38%/°C for PERC, translating to roughly 2% lower thermal losses at typical summer cell temperatures of 60-65°C. Annual power degradation of ~0.4%/year (vs. ~0.55% for PERC) results in meaningfully higher energy yield over the full 30-year operating life. - **Efficiency at the top of the segment** - Peak efficiency of 22.8% at 590 Wp puts the series on par with direct peer comparables: Talesun TM7G72M (22.8%), SunEvo SE5-72H (22.83%), and AE Solar HORIZON (22.86%). The five power variants (570-590 Wp) allow flexible layout optimization across available roof or ground area. - **30-year linear power warranty** - The manufacturer guarantees a linear degradation curve over 30 years; at ~0.4%/year this equates to approximately 87-88% of rated power at end of warranty. Many competing models in the segment offer a standard 25-year power warranty, making Horay's 30-year term a meaningful safety buffer for project lenders and investors underwriting long-tenor financing. - **Half-cut cell architecture + SMBB** - Halving the cells reduces per-cell current by 50%, cutting I²R resistive losses and heat at interconnects. The multi-busbar SMBB architecture (typically 16 busbars) shortens current paths and improves micro-crack tolerance, resulting in better performance under partial shading conditions common in urban and industrial rooftop installations. - **BNEF Tier-1 status confirmed in 2026** - Horay Solar entered the BloombergNEF Tier-1 list in Q1 2025 and retained that status in Q1 2026, confirming manufacturer bankability and eligibility for project financing by lending institutions. For utility-scale PV projects with external debt financing, Tier-1 status is a formal requirement set by most infrastructure banks and funds. ## Cons - **Monofacial design vs. bifacial peers** - The closest peer comparable in the provided dataset - Talesun TM7G72M (BIPRO) at 590 Wp - achieves the same rated power and efficiency in a bifacial configuration, which can deliver an additional 10-15% rear-side yield gain on reflective ground covers (sand, white gravel). The HS 182-144 TC Ocean is strictly monofacial, foregoing this gain in ground-mount applications. - **Short BNEF Tier-1 track record** - Horay Solar's Tier-1 BNEF status was achieved only in Q1 2025, giving the manufacturer approximately 1.5 years of confirmed bankability history, compared to LONGi, Jinko Solar, and Trina Solar, which have maintained Tier-1 standing for over a decade. In conservative project finance structures (EPC, 20+ year loans), a shorter track record may trigger additional bank due diligence requirements. ## About this series The Horay Solar HS 182-144 TC Ocean series consists of monofacial N-type modules designed for high power density and stable operation in real-world installation conditions. The use of **TOPCon N-type cells** helps to minimize degradation over time and maintain predictable energy production for many years, which directly supports the profitability of the investment. The design based on **half-cut technology** and **SMBB** improves current collection and reduces losses, allowing the modules to perform better under partial shading and in weaker light conditions, typical in many locations in Poland. Another advantage of the series is **low temperature sensitivity**, which translates into better performance in the summer and smaller energy losses on hot days. This makes it a good choice for PV farms, industrial rooftops, and commercial projects where fast installation, compatibility with popular systems, and lower BOS (Balance of System) costs are important while maintaining high reliability. ## Notable figures - Efficiency of 22.8% matches the \*\*TOPCon 550-600W\*\* median - 228.3 W/m² power density - 3.9 W/m² more than \*\*TOPCon 550-600W\*\* median (224.4 W/m²), more power per roof area - At -0.28%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - 26.0 kg weight - 5.2 kg lighter than \*\*TOPCon 550-600W\*\* median (31.2 kg), reducing installation effort - Ranked #2769 out of 14129 panels for efficiency in the database ## Questions ### What warranty does the Horay Solar HS 182-144 TC Ocean series come with? The HS 182-144 TC Ocean modules come with a 12-year product warranty covering defects in materials and workmanship, and a 30-year linear power output warranty. The 30-year power guarantee means Horay Solar commits to maintaining defined output thresholds over the module's lifetime, providing greater confidence in long-term energy yield for commercial and utility-scale projects. ### How do the N-type TOPCon cells in the HS 182-144 TC Ocean differ from standard PERC cells? N-type TOPCon cells exhibit lower light-induced degradation (LID) and a better temperature coefficient than typical PERC cells. In practice, this translates to higher efficiency throughout the module's service life and smaller output losses on hot summer days - a key advantage for commercial rooftop systems and utility-scale PV farms. ### What is the maximum power output of the Horay Solar HS 182-144 TC Ocean panel? The top variant in the series reaches 590 Wp under STC conditions. For a 182 mm 144 half-cut cell format, this represents a high power density, allowing more energy to be harvested from the same roof or ground area compared to older PERC modules of the same physical size. ### Do the Horay Solar HS 182-144 TC Ocean modules perform well under partial shading from chimneys or antennas? Yes. The half-cut cell design combined with SMBB technology limits power losses to the shaded section of the module rather than the entire string. Paired with a compatible optimizer or microinverter, the HS 182-144 TC Ocean handles irregular shading patterns common on industrial and commercial rooftops effectively. ### How does the HS 182-144 TC Ocean series handle high temperatures during summer? N-type TOPCon cells typically feature a power temperature coefficient of around -0.30%/°C, which is better than conventional PERC technology. In practice, this means smaller output losses on hot days when the module heats up significantly, resulting in higher daily and annual energy yield compared to older-generation panels. ### Is Horay Solar a Tier 1 manufacturer, and is it a suitable brand for large-scale PV projects? Yes, Horay Solar is recognized as a BNEF Tier 1 manufacturer, holds IEC and TÜV certifications, and operates multi-gigawatt annual production capacity. Tier 1 status is a standard bankability requirement from lenders and financial institutions evaluating utility-scale and commercial PV projects, making the HS 182-144 TC Ocean series a viable choice for such applications. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HS182-144TC-Ocean-590W-257013222fb3.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -30 W, cooler, +2.0 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +50 W, cooler, +2.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -35 W, cooler, +1.8 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +45 W, cooler, +1.8 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +40 W, heavier, +1.6 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | -40 W, lighter, +1.6 pp | | [Horay Solar HS570TC-MHO](https://comparepv.com/panel/horay-solar-hs570tc-mho) | 570 W | -20 W, -0.7 pp | | [Horay Solar HS575TC-MHD-D](https://comparepv.com/panel/horay-solar-hs575tc-mhd-d) | 575 W | -15 W, heavier, -0.4 pp | | [Horay Solar HS580TC-MHD-D](https://comparepv.com/panel/horay-solar-hs580tc-mhd-d) | 580 W | -10 W, heavier | | [Horay Solar HS585TC-MHO-D](https://comparepv.com/panel/horay-solar-hs585tc-mho-d) | 585 W | Heavier | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +60 W, cooler, +2.4 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/horay-solar-hs590tc-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.
