Strong in heat, no clear weak spot
The Horay Solar HS 191R-132 TC-D Basin series consists of bifacial (two-sided) N-type modules, designed to maximize energy yield in installations where every square meter and stable performance under various lighting conditions are crucial. The use of SMBB half-cell technology improves current collection and reduces heat losses within the cells, leading to improved performance not only in full sunlight, but also in cloudy conditions and in the morning. This series also features very low LID (light-induced degradation), typical for N-type modules, which makes it easier to maintain high energy production over a longer period. The glass-glass construction and IP68 junction box ensure reliability in challenging locations, while resistance to corrosive environments helps prevent standard modules from quickly losing their parameters. The HS 191R-132 TC-D Basin is a good choice for PV farms, commercial rooftops, and projects with clear surfaces, where bifaciality makes sense.
Ranking
Signals from the data
Commercial, utility-scale and shaded-installations.
Top 9% of the N-type 550-600 W segment, against a median of -0.290. Ranked 1,347th in the whole database.
Top 21% of the N-type 550-600 W segment, against a median of 22.45%.
Top 23% of the N-type 550-600 W segment, against a median of 224.5.
The 22.2-23.0% efficiency range positions this series above all three peer comparables: KDM Kingdom Solar MONO-FACIAL (22.07%), Silfab Commercial NTC (22.1%), and Suntech Ultra V (22.1%). Higher efficiency directly reduces BoS cost per installed kWp.
N-type TOPCon cells with Super Multi Busbar (SMBB) technology in a half-cut configuration reduce resistive losses and improve current collection under diffuse irradiance. Bifaciality enables additional energy yield from reflected ground irradiance (typically +5-15% on high-albedo surfaces), an advantage absent in the monofacial KDM peer comparable.
The manufacturer guarantees power output protection for 30 years, matching the upper end of the industry range for Tier 1 peers. Combined with the inherently low LID degradation of N-type cells, this translates to higher cumulative energy yield over the full project lifetime.
Horay Solar has appeared on the BloombergNEF Tier 1 PV Module Manufacturers list since Q1 2025 and maintained that status through Q1 2026. BNEF Tier 1 classification is a standard prerequisite for commercial bank project finance on utility-scale assets, reducing financing friction for investors.
Glass-glass encapsulation eliminates PID degradation risk and improves mechanical durability, while the IP68-rated junction box ensures ingress protection in high-humidity or corrosive environments (e.g., coastal or industrial sites). This is a structural advantage over glass-backsheet modules used by some competitors at this power class.
Leading global Tier 1 manufacturers - JA Solar, Trina Solar, LONGi, and Jinko Solar - offer a standard 25-year product warranty covering materials and workmanship defects. Horay Solar's 15-year term is materially shorter and may represent a risk factor during bankability assessments and insurance underwriting for projects with 25-30-year investment horizons.
Horay Solar's annual manufacturing capacity is approximately 2.5 GW, compared to 100+ GW each for the top-four global manufacturers (Jinko, LONGi, JA Solar, Trina Solar). The lower scale may affect supply continuity for large-volume orders and can reduce asset residual value in M&A transactions, where module brand recognition influences plant valuations.
- At 22.8% efficiency, this panel is on par with typical N-type 550-600W modules
- Power density of 227.7 W/m² packs 3.2 W/m² more into the same footprint vs N-type 550-600W median (224.5 W/m²)
- At -0.28%/°C, hot weather performance is typical for N-type 550-600W panels
- Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof
- In the top 20% for efficiency among all N-type panels
