For a typical 10 kWp system, this translates to approximately 0.5-1.2 m² less roof area required to achieve the same nominal system output. - **N-type TOPCon with 186R rectangular wafer** - N-type TOPCon cells exhibit LID degradation below 0.3%, while the P-type PERC cells used in peer comparables (Premier Energies) lose 1-2% of power during initial light exposure. The rectangular 186R wafer format improves cell packing density on the module compared to conventional square M10/M12 wafers, directly contributing to higher power output within standard module dimensions. - **Bifacial Double Glass - PID resistance and weather durability** - The dual-glass construction eliminates PID risk and provides superior resistance to moisture, ammonia, and UV versus backsheet-based modules. On installations with ~25% albedo (white TPO membrane, light-colored ground surfaces), the module's rear side can contribute an additional 8-15% energy yield - particularly beneficial for east-west and tracker-mounted systems. - **30-year linear power warranty** - Horay Solar backs the Alpine series with a 30-year linear performance warranty - the longest standard available for N-type TOPCon technology. For reference, peer comparable Premier Energies in the same power class (up to 560 Wp), based on PERC technology, typically carries a 25-year performance warranty. - **BNEF Tier-1 bankable manufacturer** - Horay Solar is listed on the BNEF Tier-1 Module Manufacturers report (Q1 2026), confirming the company's bankability for project financing by banks and infrastructure funds without additional manufacturer-level due diligence. Tier-1 status was first achieved in 2025 - a relatively recent entry, which should be factored into track-record assessments. ## Cons - **Product warranty: 15 years vs. 25 at some peers** - The 15-year workmanship warranty is industry-standard, but select premium-segment TOPCon manufacturers (e.g., Sunpro Power) already offer 25-year product warranties. With a 30-year performance guarantee in place, the shorter product warranty period may be material for institutional investors and projects requiring fully aligned warranty coverage throughout the module's operational life. - **Relatively small production scale (~2.5 GW/year)** - Horay Solar's annual manufacturing capacity of ~2.5 GW is substantially below industry leaders (JA Solar ~70 GW, Jinko Solar ~85 GW, Longi ~85 GW). Over a 30-year performance warranty horizon, the smaller operational scale raises justified questions about the manufacturer's long-term financial resilience - a relevant factor in LCOE modeling and risk assessment for utility-scale and externally financed projects. ## About this series The Horay Solar HS 186R-132 TC-D Alpine panel series redefines performance standards through the use of advanced **N-Type TOPCon** cells. The use of 186R rectangular silicon wafers allows for better utilization of the module surface, which translates into higher power density while maintaining optimal dimensions. The **Bifacial Double Glass** design makes these panels extremely resistant to potential-induced degradation and atmospheric factors, guaranteeing the longevity of the installation even in difficult climatic conditions. They solve the problem of power losses at high temperatures by offering a low temperature coefficient. Thanks to the ability to generate energy from both sides of the module, the Alpine series is ideal for locations with high albedo, such as roofs covered with light membranes or ground-mounted structures. **High efficiency in low light** allows for the effective operation of the installation on cloudy days, which is crucial in the Polish latitude. This series is dedicated to demanding investors seeking **Premium technology with low annual power degradation**. Compared to the competition, Alpine stands out with a reinforced frame and **resistance to snow loads**, making it a safe choice for installations in mountain regions. It is a solution that combines aesthetics with the uncompromising durability of components. ## Notable figures - At 22.5% efficiency, this panel is on par with typical \*\*N-type 500-550W\*\* modules - At 224.6 W/m² power density, roof space requirements are typical for \*\*N-type 500-550W\*\* panels - At -0.28%/°C, hot weather performance is typical for \*\*N-type 500-550W\*\* panels - At 29.5 kg (3.3 kg above \*\*N-type 500-550W\*\* median of 26.2 kg), requires checking roof load capacity - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What warranty comes with the Horay Solar HS 186R-132 TC-D Alpine panels? The Alpine series includes a 15-year product warranty from the manufacturer and a 30-year power output warranty. This means Horay Solar guarantees a defined minimum performance level for three decades. The exceptionally long power warranty is supported by the N-Type TOPCon cell technology, which exhibits a significantly lower annual power degradation rate compared to conventional PERC modules. ### Can the Alpine HS 186R-132 TC-D panels handle heavy snow loads in mountainous regions? Yes, the Alpine series was specifically designed for demanding climatic conditions, including mountain installations. Horay Solar uses a reinforced aluminum frame combined with a Bifacial Double Glass structure, which substantially increases mechanical rigidity. This design enables the module to withstand high snow and wind loads, making it a safe and reliable choice for rooftop and ground-mount systems in alpine or high-snowfall areas. ### What is N-Type TOPCon technology and why does it matter for the Alpine series? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell architecture that adds an ultra-thin tunnel oxide passivation layer to minimize carrier recombination. In real-world terms, this translates into higher conversion efficiency, a lower temperature coefficient, and slower long-term degradation compared to PERC cells. The Alpine series demonstrates these advantages with a maximum power output of 560 Wp and a 30-year power warranty. ### Will the bifacial Alpine panel perform well on a roof with a white TPO or PVC membrane? Yes, this is one of the most optimal use cases for this series. The Bifacial Double Glass construction allows the rear side of the module to harvest energy reflected from bright surfaces. White or light-gray roofing membranes typically achieve an albedo of 60-80%, which can increase energy yield by several percentage points compared to a monofacial panel of the same nominal power rating. ### How does the HS 186R-132 TC-D Alpine perform on overcast days common in Central European climates? The Alpine series delivers high efficiency under low-irradiance conditions, which is a key advantage in climates with frequent cloud cover. N-Type TOPCon cells respond better to diffuse radiation than standard PERC cells, producing more energy during overcast hours. This characteristic directly improves the overall LCOE of the installation in regions where significant portions of annual irradiation arrive as diffuse light. ### Are the rectangular 186R wafers in the Alpine series a meaningful improvement over standard cell formats? Rectangular 186R silicon wafers allow denser cell packing within the module frame without increasing its external dimensions. The result is a higher power density per square meter compared to modules using standard 182 mm or 210 mm square wafers. With 132 cells per module, the Alpine series achieves up to 560 Wp in a standard module footprint, making it particularly valuable where roof space is limited. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HS186R-132TC-D-Alpine-560W-279ba60bc9b2.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | Cooler, lighter, +2.5 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | -50 W, lighter, +2.3 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.3 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | Cooler, lighter, +2.2 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | -40 W, lighter, +2.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.1 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | -45 W, lighter, +2.0 pp | | [Horay Solar HS540TC-MHA-D](https://comparepv.com/panel/horay-solar-hs540tc-mha-d) | 540 W | Very close match | | [Horay Solar HS550TC-MHA-D](https://comparepv.com/panel/horay-solar-hs550tc-mha-d) | 550 W | Very close match | | [Horay Solar HS555TC-MHA-D](https://comparepv.com/panel/horay-solar-hs555tc-mha-d) | 555 W | +10 W, +0.4 pp | | [Horay Solar HS560TC-MHA-D](https://comparepv.com/panel/horay-solar-hs560tc-mha-d) | 560 W | +15 W, +0.6 pp | | [Gamko New Energy GKA120N-PRO-590W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-590w) | 590 W | +45 W, lighter, +1.3 pp | | [Gamko New Energy GKA120N-PRO-585W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-585w) | 585 W | +40 W, lighter, +1.1 pp | | [Bisol BGO 580](https://comparepv.com/panel/bisol-bgo-580) | 580 W | +35 W, lighter, +1.0 pp | | [Gamko New Energy GKA120N-PRO-580W](https://comparepv.com/panel/gamko-new-energy-gka120n-pro-580w) | 580 W | +35 W, lighter, +0.9 pp | --- Source: https://comparepv.com/panel/horay-solar-hs545tc-mha-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.
