Strong in heat, heavy for its output
The Horay Solar HS 182-132 TC-D Ocean series consists of double-sided N-type modules designed to maximize energy yield in environments where every kilowatt-hour counts, even under diffuse light and in challenging weather conditions. Thanks to bifacial technology, the panel can effectively utilize reflected light from the ground (e.g., a light roof, sand, or membrane), which significantly improves production compared to single-sided solutions. The use of N-type cells promotes lower degradation over time and more stable operation of the installation, which is particularly important for investors seeking predictable returns.
This series also features a glass-glass construction, which increases resistance to environmental factors and reduces the risk of microcracks during transport and installation. The modules utilize SMBB, which supports better current collection and improves the panel's performance under partial shading. This makes it a good choice for PV farms, commercial installations, and rooftop projects that require high durability and reliability.

Commercial and shaded-installations.
Weight-limited structures.
Top 10% of the TOPCon 500-550 W segment, against a median of -0.290. Ranked 1,347th in the whole database.
Bottom 21% of the TOPCon 500-550 W segment, against a median of 52.4.
At the same 540 Wp nominal power, peer comparables DMEGC GHxxxM10T-B66HST and Heliene 144HC M10 SL Bifacial reach only 20.9% efficiency. The Horay HS 182-132 TC-D requires approximately 8% less installation area for the same installed capacity - a meaningful advantage on space-constrained rooftops or ground-mount sites.
N-type cells are immune to Light-Induced Degradation (LID) and exhibit an annual degradation rate of ~0.40% vs. ~0.55-0.70% for legacy P-type PERC. Over a 30-year system lifetime this translates to several additional percentage points of retained power output compared to PERC equivalents in the same wattage class.
The rear glass replaces a polymer backsheet, reducing annual degradation to ~0.45% vs. ~0.70% for glass-backsheet configurations. It eliminates laminate delamination risk, PID (Potential-Induced Degradation), and moisture ingress - particularly valuable for utility-scale PV farms and commercial installations with a projected operational life exceeding 25 years.
Bifacial technology enables an additional 10-25% energy generation from reflected irradiance (albedo ~0.25-0.50 for white membranes or gravel). Super Multi Busbar (SMBB) shortens current collection paths, reduces resistive losses, and improves the module's tolerance to partial shading, directly boosting annual yield under real-world non-ideal conditions.
Horay Solar is listed on the BloombergNEF Tier 1 PV Module Manufacturer ranking in both Q1 2025 and Q1 2026, confirming bankability and facilitating project financing and insurance for commercial installations. The 30-year linear power warranty meets the premium standard for N-type modules and underpins predictable LCOE throughout the full investment cycle.
The glass-glass construction is approximately 25-35% heavier than glass-backsheet equivalents (~21-22 kg for this power class). For rooftop installations this may require a structural load assessment and additional mounting hardware, raising BoS costs and potentially ruling the series out for lightweight roof coverings.
Peer comparable Gokin GK-5-60HG (540 Wp) achieves 24.4% efficiency - approximately 1.7 percentage points above the 22.7% maximum of this series. For space-constrained industrial rooftops this means roughly 8% more Horay modules are needed to reach the same installed capacity as a back-contact solution.
- Efficiency of 22.5% matches the TOPCon 500-550W median
- Power density of 225.3 W/m² matches the TOPCon 500-550W median
- Temperature coefficient of -0.28%/°C matches the TOPCon 500-550W median
- At 29.0 kg (2.0 kg above TOPCon 500-550W median of 27.0 kg), requires checking roof load capacity
- Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof
