The gap translates into meaningfully higher energy yield per square meter, improving LCOE for area-constrained rooftop and C&I installations. - **N-type TOPCon: no LID, low degradation** - N-type TOPCon cells are virtually free from Light-Induced Degradation (LID), which affects all P-type PERC modules. Post-year-one annual degradation runs approximately 0.3-0.5% versus 0.5-0.7% typical for PERC. Over the 30-year power warranty horizon, the cumulative energy production advantage is material for utility-scale PV and large C&I projects. - **Bifacial glass-glass: extra yield and durability** - The double-glass (glass-glass) construction serves a dual role: it captures reflected irradiance from the ground surface (bifacial gain typically 5-15% under ground-mount conditions at albedo 0.25) and eliminates moisture and ammonia ingress through the backsheet - the primary driver of module degradation in corrosive environments such as farms, wastewater facilities, and coastal sites. - **30-year linear power warranty + BNEF Tier-1** - Horay Solar offers a 30-year linear power output warranty and a 15-year product warranty, exceeding many peer comparables that operate on 25/12-year terms. The company appears on the BNEF Tier-1 PV Module Manufacturer list for Q1 2026, the bankability benchmark required by project finance institutions for utility-scale solar assets. - **IEC61215:2021 and IEC61730:2023 certified** - Alpine series modules carry current IEC61215:2021 (electrical and mechanical performance) and IEC61730:2023 (safety) certifications, satisfying grid interconnection and insurance requirements in Poland and across the EU. The 2023 edition of IEC61730 applies more stringent mechanical load test levels (typically 5400/2400 Pa for snow/wind), confirming structural robustness. ## Cons - **Limited European service network** - Horay Solar's annual module production capacity of approximately 2.5 GW is substantially smaller than that of Jinko Solar, LONGi, or JA Solar (each exceeding 60 GW). The company is still building its European footprint - its KEY ENERGY 2025 innovation award was part of a strategy to strengthen European distribution. In the event of warranty claims or module replacements, local service response times may be longer than with suppliers who have well-established European logistics infrastructure. ## About this series Horay Solar HS 186R-144 TC-D Alpine photovoltaic panels utilize **N-type TOPCon cell technology**, ensuring exceptional energy conversion efficiency even in low sunlight. The use of innovative, rectangular 186R cells allows for power density optimization, which directly translates into higher yields per square meter of the installation. This series stands out with its **bifacial design**, which, thanks to the glass coating on both sides of the module, enables the absorption of light reflected from the ground, significantly increasing total electricity production. It is an ideal solution for demanding commercial investments and solar farms, where **resistance to extreme mechanical loads**, such as heavy snow or strong wind, is of key importance. Thanks to a low temperature coefficient, Alpine panels operate stably even on hot days, minimizing energy losses. These modules solve the problem of rapid cell degradation by offering **double glass-glass protection**, which effectively protects the silicon from the effects of moisture and ammonia. By choosing this series, you are investing in technology that outperforms the competition in terms of durability and return on investment in harsh environmental conditions. ## Notable figures - At 22.5% efficiency, this panel is on par with typical \*\*N-type 550-600W\*\* modules - Power density of 224.9 W/m² matches the \*\*N-type 550-600W\*\* median - At -0.28%/°C, hot weather performance is typical for \*\*N-type 550-600W\*\* panels - At 32.5 kg, this panel is 2.2 kg heavier than the \*\*N-type 550-600W\*\* median (30.3 kg) - more demanding for installation crews - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof ## Questions ### What is the warranty on Horay Solar HS 186R-144 TC-D Alpine panels? The Alpine series comes with a 15-year product warranty covering manufacturing defects and a 30-year linear power warranty. The glass-glass construction slows degradation compared to backsheet modules, supporting the extended power guarantee. Horay Solar's Tier 1 status further validates the credibility of these long-term commitments. ### What does bifacial technology mean for the Alpine series, and how much extra energy can I expect? The bifacial glass-glass design allows the rear side of the module to absorb light reflected from the ground surface. On utility-scale installations with light-colored gravel or white ground covers, energy yield can increase by 5-15% compared to a monofacial module with the same front-side power rating. Actual gain depends on ground albedo and tilt angle. ### How do N-type TOPCon cells in the Alpine series compare to standard PERC? N-type TOPCon cells offer a lower temperature coefficient (approximately -0.30%/°C vs. -0.35%/°C for PERC) and a slower annual degradation rate - below 0.4% vs. approximately 0.55% for PERC. This translates to higher lifetime energy production over 30 years and better performance on hot days when module temperature exceeds 50°C. ### Do Horay Solar Alpine 610 Wp panels perform well in low-irradiance and winter conditions? Yes. N-type TOPCon cells provide superior spectral response under diffuse light compared to PERC. The Alpine module produces measurably more energy under overcast skies and low sun angles typical of Central European winters. The low temperature coefficient further reduces energy losses during hot summer days, improving year-round LCOE. ### What mechanical load ratings do HS 186R-144 TC-D Alpine modules carry, and are they suitable for mountain or high-wind sites? The Alpine series is engineered for extreme environmental conditions. Modules are IEC-certified for 5,400 Pa snow load and 2,400 Pa wind load. The rigid glass-glass structure enhances frame stiffness and vibration resistance, making this series an ideal choice for mountain installations, high-wind sites, and regions with heavy snowfall. ### What commercial applications are Horay Solar HS 186R-144 TC-D Alpine 610 Wp modules best suited for? The 610 Wp peak power and large 186R rectangular cells enable higher power density per square meter, reducing BoS costs and racking requirements. The Alpine series is optimized for utility-scale solar farms, large industrial rooftops, and energy storage projects. Modules are compatible with mainstream string inverters featuring 1000 V and 1500 V MPPT inputs. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HS186R-144TC-D-Alpine-610W-030e50575f1b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +50 W, lighter, +2.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -35 W, lighter, +2.3 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +45 W, lighter, +2.3 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -40 W, lighter, +2.1 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +40 W, lighter, +2.1 pp | | [Horay Solar HS590TC-MHA](https://comparepv.com/panel/horay-solar-hs590tc-mha) | 590 W | Lighter | | [Horay Solar HS600TC-MHA](https://comparepv.com/panel/horay-solar-hs600tc-mha) | 600 W | Lighter | | [Horay Solar HS605TC-MHA-D](https://comparepv.com/panel/horay-solar-hs605tc-mha-d) | 605 W | +10 W, +0.4 pp | | [Horay Solar HS610TC-MHA](https://comparepv.com/panel/horay-solar-hs610tc-mha) | 610 W | +15 W, lighter, +0.6 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +55 W, lighter, +2.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +85 W, lighter, +2.7 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +80 W, lighter, +2.5 pp | | [WINAICO WST-675BKX72-A2](https://comparepv.com/panel/winaico-wst-675bkx72-a2) | 675 W | +80 W, cooler, +2.5 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +75 W, lighter, +2.3 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +75 W, lighter, +2.3 pp | --- Source: https://comparepv.com/panel/horay-solar-hs595tc-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.
