N-type architecture also eliminates LID (Light Induced Degradation) common in PERC cells. - **Reinforced Alpine-series frame** - The Alpine frame is engineered for elevated snow and wind loads, directly addressing Central European and Scandinavian installation conditions. For prosumer rooftop systems in Poland, where snow loads per EN 1991-1-3 reach 0.7–1.6 kN/m² across most zones, this is a critical structural advantage. - **30-year linear power warranty** - The manufacturer guarantees maximum annual degradation of ≤0.45% post year 1, implying >86.5% of nameplate power after 30 years. Standard Chinese Tier-1 warranties (LONGi, JA Solar) cover 25 years with degradation to 84.8%; the Alpine series extends linear protection by 5 additional years. - **BNEF Tier-1 status and bankability** - Horay Solar attained BNEF Tier-1 status in Q1 2025, confirming the bankability required by European project finance institutions. Annual nameplate capacity of 2.5 GW/year and a European after-sales service hub in Valencia reduce supply-chain and O&M risk for institutional investors and IPP developers. - **Half-cut cell layout (108 cells)** - The 108 half-cut cell configuration splits the module into two independently operating sub-circuits, reducing resistive losses and limiting partial-shading impact on the full string. In a typical rooftop installation with chimney or antenna shading, half-cut technology preserves up to 50% of the lower sub-circuit's output without degrading the upper one. ## Cons - **Monofacial-only format** - The HS 186R-108 TC Alpine series has no bifacial variant (is\_bifacial: false), while the comparable 455 Wp segment increasingly offers bifacial modules with 5–15% rear-side gain depending on ground albedo. Horay provides bifacial only in the 144-cell format (Alpine TC-D series), ruling out this series for flat-roof white-membrane applications or ground-mount utility projects. - **Shorter European track record vs. market leaders** - Horay Solar joined the BNEF Tier-1 list only in Q1 2025, while LONGi, JA Solar, and Jinko have held continuous Tier-1 status since 2013–2015. The shorter European deployment history may result in higher insurance premiums or more conservative product assessments by lenders financing projects above 1 MWp. ## About this series Horay Solar HS 186R-108 TC Alpine is a series of modules utilizing advanced **N-type TOPCon** technology, which redefines efficiency standards in prosumer and commercial installations. Thanks to the use of innovative 186R rectangular cells, these panels offer significantly higher power density while maintaining compact dimensions, which directly translates into optimal utilization of the available roof surface. Exceptional resistance to light-induced degradation ensures that the system maintains its performance for decades, addressing the problem of premature component aging. **High module efficiency** exceeding standard market thresholds allows for generating more electricity from the same unit of area. The Alpine series is distinguished by a reinforced frame design, making it an ideal solution for regions with heavy snow loads, ensuring the safety and stability of the structure. The use of **half-cut cell technology** reduces losses resulting from partial shading, clearly setting this product apart from older competitor solutions. It is the optimal choice for investors who prioritize an **excellent temperature coefficient** and modern finishing aesthetics, guaranteeing a harmonious integration with the roof surface. ## Notable figures - Efficiency of 22.8% matches the \*\*N-type 450-500W\*\* median - At 227.7 W/m² power density, roof space requirements are typical for \*\*N-type 450-500W\*\* panels - Temperature coefficient of -0.28%/°C matches the \*\*N-type 450-500W\*\* median - 20.5 kg weight - 3.2 kg lighter than \*\*N-type 450-500W\*\* median (23.7 kg), reducing installation effort - Ranked #2714 out of 14005 panels for efficiency in the database ## Questions ### What warranty does the Horay Solar HS 186R-108 TC Alpine series come with? The HS 186R-108 TC Alpine series comes with a 12-year product warranty covering material and workmanship defects, and a 30-year linear power output warranty. This means the manufacturer guarantees a defined minimum performance level for three decades. As a Tier 1 manufacturer, Horay Solar has the financial standing to back these long-term commitments. ### Are Horay Solar Alpine panels suitable for regions with heavy snowfall? Yes, the Alpine series was specifically designed for demanding climates. Its reinforced aluminum frame provides increased snow load resistance compared to standard modules in this class. This makes it a solid choice for rooftop installations in mountainous areas, flat roofs where snow tends to accumulate, and any region with harsh winters. ### What is N-type TOPCon technology and how does it differ from standard PERC cells? TOPCon (Tunnel Oxide Passivated Contact) is an N-type silicon cell with an additional passivation layer that reduces carrier recombination. In practice this means higher module efficiency, a better temperature coefficient (less power loss on hot days), and exceptionally low light-induced degradation (LID). PERC cells rely on P-type silicon and underperform TOPCon in all three of these areas. ### What is the peak power output of the HS 186R-108 TC Alpine and what efficiency does it achieve? The module's maximum peak power is 455 Wp under STC conditions. The series uses 108 rectangular 186R half-cut TOPCon cells, enabling module efficiency that exceeds typical benchmarks for residential and commercial installations. The higher power density means more energy can be harvested from the same roof area compared to older PERC modules. ### Are the HS 186R-108 TC Alpine modules bifacial? No, the HS 186R-108 TC Alpine series is a monofacial module. Power is generated only from the front surface. This works well for standard rooftop installations where ground-reflected irradiance is minimal anyway, and the dark backsheet provides a clean aesthetic that blends naturally into the roof surface. ### Is Horay Solar a reliable manufacturer and are their panels worth buying? Horay Solar holds Tier 1 status from independent industry analysts, confirming bankable creditworthiness and a documented production track record. The company is headquartered in China and focuses on crystalline PV modules. Tier 1 classification matters when securing project financing and is a meaningful signal that the manufacturer is likely to honor a 30-year power warranty — something not every brand can credibly guarantee. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HS186R-108TC-Alpine-455W-2e3d53693c7f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +40 W, cooler, +2.0 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +50 W, cooler, +1.9 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +35 W, cooler, +1.7 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +45 W, cooler, +1.7 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +45 W, cooler, +1.7 pp | | [Gokin GK-3-54HGb-500M](https://comparepv.com/panel/gokin-gk-3-54hgb-500m) | 500 W | +45 W, cooler, +1.7 pp | | [Horay Solar HS435TC-MHC-D](https://comparepv.com/panel/horay-solar-hs435tc-mhc-d) | 435 W | -20 W, heavier, -1.0 pp | | [Horay Solar HS440TC-MHC-D](https://comparepv.com/panel/horay-solar-hs440tc-mhc-d) | 440 W | -15 W, heavier, -0.8 pp | | [Horay Solar HS445TC-MHC-D](https://comparepv.com/panel/horay-solar-hs445tc-mhc-d) | 445 W | -10 W, heavier, -0.5 pp | | [Horay Solar HS450TC-MHC-D](https://comparepv.com/panel/horay-solar-hs450tc-mhc-d) | 450 W | Heavier, -0.3 pp | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +55 W, cooler, +2.2 pp | --- Source: https://comparepv.com/panel/horay-solar-hs455tc-mha 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.
