Higher efficiency directly reduces BoS cost per installed kWp. - **Bifacial N-type with SMBB half-cut** - 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. - **30-year linear power warranty** - 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. - **BNEF Tier 1 status - confirmed bankability** - 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 construction with IP68 junction box** - 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. ## Cons - **Product warranty limited to 15 years** - 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. - **Small production scale vs. global leaders** - 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. ## About this series 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. ## Notable figures - 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 ## Questions ### What warranty comes with the Horay Solar HS 191R-132 TC-D Basin panels? The manufacturer provides a 15-year product warranty covering physical defects and workmanship, plus a 30-year linear power output warranty. Over three decades, the module must maintain output above the guaranteed degradation threshold. For utility-scale PV farms and commercial rooftops, this extended warranty horizon is a key factor in LCOE calculations, reducing the risk of unplanned replacement costs. ### What does bifacial mean, and when will the HS 191R-132 TC-D Basin actually benefit from it? A bifacial module captures light on both the front and rear surfaces, using irradiance reflected from the ground. The HS 191R-132 TC-D Basin achieves the highest bifacial gain on farms with light-colored ground surfaces such as concrete, sand, snow, or white roofing membranes, and on elevated racking systems with adequate air gap. On dark substrates with minimal clearance, bifacial gain will be negligible. ### Do N-type cells in the HS 191R-132 TC-D Basin degrade less than standard PERC? Yes. N-type cells exhibit very low LID (Light Induced Degradation), which can be measurable in P-type PERC cells within the first hours of operation. As a result, the HS 191R-132 TC-D Basin retains near-nominal power output from day one and maintains higher energy yield throughout the full 30-year power warranty period - an important advantage for projects settled on a per-kilowatt-hour basis over a long horizon. ### Does the Horay Solar HS 191R-132 TC-D Basin perform well in overcast conditions? Yes. The SMBB half-cut cell technology improves current collection under diffuse and low-irradiance light, and N-type cells begin generating current at lower irradiance levels than PERC. The glass-glass construction and IP68-rated junction box reliably handle moisture and precipitation. The series performs well not only in high-irradiance locations but also in regions with frequent cloud cover. ### What installations is the Horay Solar HS 191R-132 TC-D Basin 570 Wp best suited for? The series is optimized for utility-scale PV farms, large commercial rooftops, and ground-mount projects with light-colored ground surfaces where bifacial gain is meaningful. The 570 Wp power rating reduces module count and overall BoS costs for a given system size. Resistance to corrosive environments also makes it a solid choice for coastal or industrial sites where standard P-type modules tend to degrade faster. ### Is Horay Solar a Tier 1 manufacturer, and can they be trusted for a large project? Yes, Horay Solar is classified as a Tier 1 manufacturer, reflecting a positive assessment of production capacity, quality control, and financial stability by independent industry agencies. The company is headquartered in China. Before signing a contract for a large project, it is advisable to confirm current IEC certification with your distributor and verify warranty claim procedures through a local representative. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/hs191r-132tc-d-basin-570w-49d11ba0fc90.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.0 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +1.8 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +1.6 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -25 W, lighter, +1.6 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | -25 W, lighter, +1.6 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | Cooler, lighter, +1.5 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +1.4 pp | | [Horay Solar HS550TC-MHB](https://comparepv.com/panel/horay-solar-hs550tc-mhb) | 550 W | -15 W, lighter, -0.6 pp | | [Horay Solar HS550TC-MHC-D](https://comparepv.com/panel/horay-solar-hs550tc-mhc-d) | 550 W | -15 W, -0.5 pp | | [Horay Solar HS555TC-MHB-D](https://comparepv.com/panel/horay-solar-hs555tc-mhb-d) | 555 W | -10 W, -0.4 pp | | [Horay Solar HS555TC-MHC-D](https://comparepv.com/panel/horay-solar-hs555tc-mhc-d) | 555 W | -10 W, -0.3 pp | | [Horay Solar HS560TC-MHB-D](https://comparepv.com/panel/horay-solar-hs560tc-mhb-d) | 560 W | Very close match | | [Horay Solar HS560TC-MHC-D](https://comparepv.com/panel/horay-solar-hs560tc-mhc-d) | 560 W | Very close match | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +85 W, lighter, +2.4 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +80 W, lighter, +2.2 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +75 W, lighter, +2.0 pp | --- Source: https://comparepv.com/panel/horay-solar-hs565tc-mhb-d Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
