Light for its output, no clear weak spot
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.
Ranking
Signals from the data
Commercial, utility-scale, shaded-installations and hot-climate.
Top 4% of the TOPCon 550-600 W segment, against a median of 53.8. Ranked 542nd in the whole database.
Top 5% of the TOPCon 550-600 W segment, against a median of -0.290. Ranked 1,347th in the whole database.
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.
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.
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.
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.
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.
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.
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.
