This is the current N-type TOPCon industry benchmark for 2025–2026 and is materially better than legacy 25-year PERC warranties that typically allowed a decline to 80–84.8% by year 25. - **BNEF Tier-1 status – confirmed bankability** - Horay Solar has been listed on the BloombergNEF Tier-1 PV Module Manufacturer list since Q1 2025, with continued inclusion confirmed in Q1 2026. Tier-1 status is a prerequisite for debt financing and manufacturer warranty insurance on commercial and utility-scale PV projects, making this series fully bankable for institutional investors. ## Cons - **Monofacial design – no bifacial yield gain** - The Basin series is monofacial (is\_bifacial: false), while a direct peer — MY Solar G&A N-Type TOPCon Bifacial — offers the same 620 Wp peak power and near-identical efficiency (22.95%) in a bifacial configuration. With typical bifaciality factors of 0.65–0.80, bifacial modules generate 8–20% additional energy yield in ground-mount and agrivoltaic installations on reflective surfaces (sand, concrete, snow), directly lowering project LCOE. For utility-scale PV farms where bifacial gain is a standard design assumption, this is a notable competitive limitation. ## About this series The Horay Solar HS 191R-144 TC Basin panel series is an advanced solution based on **N-type TOPCon cell technology**, which redefines efficiency standards in demanding commercial installations. These panels effectively eliminate the problem of light-induced degradation, offering significantly better long-term power stability compared to older generation modules. Thanks to the use of a **bifacial glass-glass construction**, the Basin series exhibits extreme resistance to aggressive external factors such as ammonia or high humidity, making it an ideal choice for modern agriculture and photovoltaic farms. The use of **high-density rectangular cells** allows for maximizing yields from the available mounting surface, which directly translates to a lower LCOE and faster return on investment.

By choosing this series, investors receive a product that combines innovation with **exceptional mechanical durability**, guaranteeing energy security for decades. This is equipment designed for professionals for whom reliability and maximizing energy production in all lighting conditions are key. ## Notable figures - At 22.2% efficiency, this panel is 0.6pp below the \*\*N-type 600-650W\*\* median of 22.8% - Power density of 222.1 W/m² is 5.6 W/m² below \*\*N-type 600-650W\*\* median (227.7 W/m²) - needs more roof space - Temperature coefficient of -0.28%/°C matches the \*\*N-type 600-650W\*\* median - Weight of 28.0 kg (4.5 kg below \*\*N-type 600-650W\*\* median of 32.5 kg) allows easier transport and roof mounting - Ranked #5817 out of 14005 panels for efficiency in the database ## Questions ### How does N-type TOPCon technology in the Horay Solar HS 191R-144 TC Basin series differ from older PERC panels? N-type TOPCon cells use n-doped silicon with a passivated tunnel oxide layer, which virtually eliminates light-induced degradation (LID). In practice, the panel does not lose several percent of rated power after the first season, as typical PERC modules do. The result is higher cumulative energy yield over the full 30-year service life and a lower LCOE for the entire installation. ### What warranty does the Horay Solar HS 191R-144 TC Basin series carry? The HS 191R-144 TC Basin series comes with a 12-year product warranty covering material and workmanship defects, along with a 30-year linear power output warranty. This means the panel retains a guaranteed percentage of its rated power for three decades. These are standard terms for premium N-type TOPCon modules in the commercial segment and confirm the long-term security of the investment. ### How does the HS 191R-144 TC Basin panel perform in high summer temperatures? N-type TOPCon technology delivers a superior temperature coefficient compared to standard PERC modules, meaning the panel loses less power as cell temperature rises. On hot summer days, the Basin series generates measurably more energy than a PERC module of the same rated wattage. This is especially relevant in agrivoltaic and utility-scale PV farms with long daily peak irradiance hours. ### Are the HS 191R-144 TC Basin panels suitable for agrivoltaic and agricultural installations? Yes, the Basin series was designed for the harsh environmental conditions typical of agriculture. The glass-glass construction provides certified resistance to ammonia vapor from fertilizers and livestock, as well as prolonged high humidity. This makes the modules a reliable choice both over crop fields and near livestock buildings, where conventional backsheet modules tend to degrade prematurely. ### What is the maximum power output of the Horay Solar HS 191R-144 TC Basin panel, and is 620 Wp sufficient for large commercial installations? The top variant in the series reaches 620 Wp, placing it among the most powerful modules in the 144 half-cut cell format. In commercial installations from 100 kWp upward, this high per-panel wattage reduces total module count, cutting Balance-of-System (BoS) costs — fewer mounting structures, less DC cabling, and fewer string connections. For utility-scale PV farms, it translates directly to a lower project LCOE. ### Is Horay Solar a reputable manufacturer? Do they hold Tier 1 status? Yes, Horay Solar is listed on the BloombergNEF Tier 1 module manufacturer ranking, confirming the company's bankability and credibility with global financial institutions. Founded in 2010 and headquartered in Wuxi, Jiangsu Province, China, the company holds TÜV, IEC, and CE certifications and operates with an annual production capacity exceeding 2.5 GW. Tier 1 status is a key criterion for securing bank financing on commercial and utility-scale projects using these modules. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HS191R-144TC-Basin-620W-840d90496d70.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +50 W, cooler, +3.0 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +45 W, cooler, +2.8 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -40 W, lighter, +2.6 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +40 W, cooler, +2.6 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -45 W, lighter, +2.4 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +35 W, cooler, +2.4 pp | | [Horay Solar HS605TC-MHB](https://comparepv.com/panel/horay-solar-hs605tc-mhb) | 605 W | Very close match | | [Horay Solar HS610TC-MHC-D](https://comparepv.com/panel/horay-solar-hs610tc-mhc-d) | 610 W | +10 W, heavier, +0.4 pp | | [Horay Solar HS615TC-MHC-D](https://comparepv.com/panel/horay-solar-hs615tc-mhc-d) | 615 W | +15 W, heavier, +0.6 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +80 W, cooler, +3.0 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +75 W, cooler, +2.8 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +100 W, heavier, +2.8 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +95 W, heavier, +2.7 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +70 W, cooler, +2.6 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +70 W, cooler, +2.6 pp | | [Jinko Solar JKM650-670N-66QL6-BDV (670W class)](https://comparepv.com/panel/jinko-solar-jkm650-670n-66ql6-bdv-670w-class) | 670 W | +70 W, heavier, +2.6 pp | --- Source: https://comparepv.com/panel/horay-solar-hs600tc-mhb Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
