Strong in heat, no clear weak spot
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.
Ranking
Signals from the data
Commercial and utility-scale.
Top 5% of the TOPCon 550-600 W segment, against a median of -0.290. Ranked 1,347th in the whole database.
The HS 182-144 TC-D Ocean achieves peak module efficiency of 22.8%, matching direct peer comparables: Talesun TM7G72M (22.8%), and slightly trailing AE Solar HORIZON CMD-144BDS (22.86%) and SunEvo SE5-72H (22.83%). 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 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.
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.
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.
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.
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.
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.
