For a typical 100 kWp system, this translates to roughly 700-1,550 Wp of additional installed power on the same roof or ground footprint. - **N-type TOPCon with 186R rectangular wafer** - N-type TOPCon cells exhibit significantly lower light-induced degradation (LID \< 0.5% vs ~1.5% for PERC) and a better temperature coefficient (typically -0.30%/°C vs -0.35%/°C for PERC), meaningfully increasing annual energy yield in the Polish climate where modules routinely reach 60-75°C in summer. The rectangular 186R wafer format increases cell packing density versus standard 182M wafers. - **SMBB - microfracture resistance** - Super Multi Busbar (SMBB) shortens current pathways and reduces resistive losses. Its key operational benefit is high resistance to microcracking (PID), which in practice means lower post-transport and post-installation power loss - a material advantage for utility-scale projects where modules undergo repeated mechanical stress during handling and racking. - **BNEF Tier 1 - confirmed bankability** - Horay Solar is listed on the BNEF Tier 1 Module Manufacturer report for Q1 2026 (ranked 37th, 2,500 MW manufacturing capacity). Tier 1 status is the standard prerequisite for project finance transactions at banks and infrastructure funds, allowing these modules to be used in PPA-backed deals without additional technical due diligence conditions. - **30-year linear power warranty** - The manufacturer guarantees a linear power degradation schedule over 30 years - aligned with the longest PPA terms used in Poland's renewable energy sector. Comparable-wattage peers such as GCL and Seraphim offer 25-year power warranties as standard, giving the Alpine series a favorable edge in NPV models for utility-scale PV projects. ## Cons - **12-year product warranty - below premium standard** - The standard product warranty is 12 years, while leading N-type TOPCon manufacturers in the same power class (JA Solar DeepBlue 4.0 Pro, Jinko Tiger Neo, LONGi Hi-MO 9, Canadian Solar TOPHiKu7) offer 15-year module warranties. For utility-scale installations this creates elevated replacement cost risk in the 12-15-year window, which is typically not covered by project insurance policies. - **Limited brand recognition and service network in Poland** - With 2,500 MW of manufacturing capacity and a BNEF rank of 37, Horay Solar operates at roughly 1/10th the scale of LONGi or Jinko Solar. The absence of a documented authorized service network in Poland can extend warranty claim resolution times, which is a material concern for O&M contracts that include availability guarantees. ## About this series The Horay Solar HS 186R-144 TC Alpine panel series redefines performance standards through the use of advanced **N-type TOPCon** cells. The use of rectangular silicon wafers in the 186R format allows for optimal utilization of the module surface area, which translates into significantly higher power density compared to traditional solutions. The **Bifacial Double Glass** construction ensures not only additional energy yield from reflected radiation but also exceptional resistance to extreme mechanical loads, which is crucial in the variable Polish climate. Alpine series modules effectively solve the problem of light-induced degradation, offering stable operation and **minimized degradation** of power over the long term. Thanks to an excellent temperature coefficient, these panels maintain high efficiency even during summer heat, making them an ideal choice for **large-scale solar farms** and modern commercial installations. What sets this series apart from the competition is **SMBB technology**, which improves current flow and increases the cells' resistance to micro-cracks. Investing in the Alpine line is a guarantee of maximizing yields while lowering the total cost of energy production, placing these modules at the forefront of the most cost-effective solutions on today's PV market. ## Notable figures - At 22.5% efficiency, this panel is on par with typical \*\*N-type 550-600W\*\* modules - At 224.9 W/m² power density, roof space requirements are typical for \*\*N-type 550-600W\*\* panels - At -0.28%/°C, hot weather performance is typical for \*\*N-type 550-600W\*\* panels - At 27.0 kg, this panel is 3.3 kg lighter than \*\*N-type 550-600W\*\* median (30.3 kg) - easier handling during installation - In the top 30% for efficiency among all N-type panels ## Questions ### What is the peak power output of the Horay Solar HS 186R-144 TC Alpine and what cell technology does it use? The HS 186R-144 TC Alpine series reaches up to 610 Wp peak power. The modules use N-type TOPCon cells, which deliver higher efficiency and lower long-term degradation compared to standard PERC technology. The 186R format refers to rectangular silicon wafers that maximize active area coverage across the module surface, resulting in a higher power density per square meter. ### What warranties does Horay Solar offer on the Alpine series - product and power output? Horay Solar provides a 12-year product warranty and a 30-year linear power output warranty on the Alpine series. The 30-year guarantee ensures the module maintains efficiency above a defined threshold over three decades. As a Tier-1 manufacturer, Horay Solar also offers greater confidence in long-term after-sales support compared to lower-tier suppliers. ### What is SMBB technology in the Alpine panels and does it make a real difference? SMBB (Super Multi Busbar) replaces a few wide busbars with many thin ones per cell. The shorter current path to each busbar reduces resistive losses and boosts energy yield. More importantly for end users, SMBB reduces mechanical stress within the cell, making the module significantly more resistant to microcracks caused by handling, transport stress, or wind and snow loads. ### Are the Horay Solar HS 186R-144 TC Alpine panels suited for large-scale solar farms or only for rooftop installs? The Alpine series is primarily designed for utility-scale solar farms and commercial installations. The high unit power (up to 610 Wp), double glass construction, and N-type TOPCon cells combine to deliver a low LCOE at scale. The modules also perform well on large commercial or industrial rooftops where maximizing energy output per available area is the primary goal. ### How do the Alpine panels perform in high temperatures - does heat significantly reduce their output? N-type TOPCon cells have a more favorable temperature coefficient than older PERC technology, meaning proportionally less power loss as module temperature rises. On hot summer days when cell temperature exceeds 60°C, Alpine modules retain more of their rated output than typical PERC panels. This advantage is most noticeable during peak summer hours when the system is working hardest. ### Does the double glass construction of the Alpine series complicate installation compared to standard backsheet modules? Double glass modules are slightly heavier than backsheet equivalents, which needs to be factored into racking design and logistics. In return, you get significantly better resistance to moisture ingress, ammonia, and mechanical loads - critical for ground-mount farms exposed to hail, heavy snow, or high wind. Installation simply requires clamps rated for dual-glass modules, which are widely available from standard BoS suppliers. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HS186R-144TC-Alpine-610W-5439696ccc13.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +50 W, cooler, +2.5 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -35 W, cooler, +2.3 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +45 W, cooler, +2.3 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -40 W, cooler, +2.1 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +40 W, cooler, +2.1 pp | | [Horay Solar HS590TC-MHA](https://comparepv.com/panel/horay-solar-hs590tc-mha) | 590 W | Very close match | | [Horay Solar HS600TC-MHA](https://comparepv.com/panel/horay-solar-hs600tc-mha) | 600 W | Very close match | | [Horay Solar HS605TC-MHA-D](https://comparepv.com/panel/horay-solar-hs605tc-mha-d) | 605 W | +10 W, heavier, +0.4 pp | | [Horay Solar HS610TC-MHA](https://comparepv.com/panel/horay-solar-hs610tc-mha) | 610 W | +15 W, +0.6 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +55 W, cooler, +2.7 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +85 W, cooler, +2.7 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +80 W, cooler, +2.5 pp | | [WINAICO WST-675BKX72-A2](https://comparepv.com/panel/winaico-wst-675bkx72-a2) | 675 W | +80 W, heavier, +2.5 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +75 W, cooler, +2.3 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +75 W, cooler, +2.3 pp | --- Source: https://comparepv.com/panel/horay-solar-hs595tc-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.
