The ~1 pp advantage translates to tangible savings in roof or field area for the same installed capacity. - **Bifacial glass-glass vs. monofacial competitors** - All three peer-comparable products (KDM, Silfab NTC, Suntech Ultra V) are monofacial modules. The Cosmos glass-glass bifacial construction enables additional rear-side energy yield from albedo reflections of 5-25% (typically 10-15% in ground-mount systems with light-colored ground), with a meaningful contribution during snow-covered periods of approximately 3-4 months per year in Polish climate conditions. - **30-year linear power warranty - 87.4% after year 30** - The manufacturer guarantees ≥87.4% of nominal power output after 30 years of operation (degradation ≤0.4%/year after year one), exceeding the market-standard 25-year linear warranty offered by many leading Tier-1 manufacturers. The extended warranty horizon reduces project bankability risk and improves LCOE calculations. - **N-type TOPCon - low LID degradation and better thermal performance** - N-type TOPCon cells exhibit light-induced degradation (LID) of \<1%, compared to 1.5-2% for PERC technology. The Pmax temperature coefficient for Cosmos 210R series modules is typically -0.30%/°C, delivering approximately 2-3% higher yield at typical summer operating temperatures (65-70°C module temp) versus PERC modules at -0.35%/°C. - **BNEF Tier 1 Q1 2026 + industrial certifications** - Horay Solar has been listed on the BloombergNEF Tier 1 PV Module Manufacturer list since Q1 2025 (reconfirmed Q1 2026), meeting the bankability requirement for most utility-scale and commercial PV project financing. The Cosmos series has passed salt mist (IEC 61701) and ammonia (IEC 62716) resistance testing, qualifying installations at agricultural facilities, industrial sites, and coastal locations. ## Cons - **15-year product warranty below market standard** - The product warranty covers 15 years, while leading Tier-1 manufacturers in the same commercial power class (Jinko Solar, LONGi, Canadian Solar) standardly offer 25-year product warranties. For projects with bank financing or insurance requirements extending beyond 15 years, this may require additional arrangements with the insurer or O&M provider. ## About this series The Horay Solar HS 210R-120 TC-D Cosmos series is a range of bifacial N-type modules designed to maximize energy yield not only from the front, but also from reflected light off the ground. Thanks to its glass-glass construction and anti-reflective coating, it operates more stably in demanding conditions and better utilizes diffuse light, resulting in more predictable energy production in the Polish climate. The use of **SMBB half-cell** improves current collection in the cells and reduces thermal losses, supporting higher operating efficiency in installations exposed to heat. Another advantage is **N-type with very low LID degradation**, meaning a smaller power drop over time and more reliable investment returns. The series also boasts **high resistance to harsh environments** - tests with solar fog and ammonia make it suitable for industrial applications, on farms, in warehouses, and in agricultural facilities. This is the choice for investors who want **long-term linear warranty** and a module that performs reliably in real-world conditions, rather than just in tables. ## Notable figures - At 23.1% efficiency, this panel is 0.7pp above typical \*\*TOPCon 550-600W\*\* modules (median: 22.4%) - At 230.8 W/m² power density, this panel generates 6.4 W/m² more per unit area than \*\*TOPCon 550-600W\*\* median (224.4 W/m²) - At -0.28%/°C, hot weather performance is typical for \*\*TOPCon 550-600W\*\* panels - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - #1617 for efficiency, #1347 for temperature performance out of 14129 panels ## Questions ### What is the peak power output of the Horay Solar HS 210R-120 TC-D Cosmos module, and what cell technology does it use? The HS 210R-120 TC-D Cosmos reaches a peak power output of up to 570 Wp. It uses N-type TOPCon cells in an SMBB half-cut configuration, delivering high conversion efficiency and reduced resistive losses. Horay Solar holds BNEF Tier 1 status, confirming consistent manufacturing quality and long-term supplier reliability. ### What warranty does the Horay Solar HS 210R-120 TC-D Cosmos series carry? The module comes with a 15-year product warranty covering material and workmanship defects, plus a 30-year linear power output warranty. N-type TOPCon cells feature very low LID (Light Induced Degradation), so the module maintains output closer to its rated value throughout its lifetime. The linear warranty structure guarantees a defined minimum power output for each year of operation. ### Are the HS 210R-120 TC-D Cosmos modules suitable for utility-scale solar farms with single-axis trackers? Yes. The bifacial glass-glass construction makes the Cosmos series well-suited for ground-mounted farms on single-axis tracker systems. The rear side captures reflected light from the ground (albedo effect), boosting energy yield by several percentage points depending on surface type and tilt angle. Higher yield directly reduces the project's LCOE. ### How does the bifacial design work in the Cosmos series, and does it make sense in Central European climates? A bifacial module generates electricity from both the front and rear surfaces by capturing light reflected from snow, light-colored gravel, or concrete. In Central Europe, bifacial gains are meaningful - especially in winter when snow cover significantly boosts albedo. The glass-glass construction and anti-reflective coating of the HS 210R-120 TC-D further improve harvesting of diffuse light, common under Polish weather conditions. ### Do the N-type TOPCon cells in the Horay Solar HS 210R-120 TC-D Cosmos degrade more slowly than conventional P-type panels? Yes. TOPCon N-type cells exhibit very low LID, meaning they do not experience the sharp initial power drop seen in older P-type PERC modules right after commissioning. In practice, this results in higher energy production during the first years of operation and more predictable ROI across the full 30-year linear power warranty period. ### Is the Horay Solar Cosmos HS 210R-120 TC-D suitable for agricultural or industrial installations? Yes. The series has passed salt mist and ammonia resistance tests, qualifying it for installations near industrial facilities, livestock farms, and agricultural buildings. The rigid glass-glass construction adds mechanical durability in harsh environments. The environmental certifications also help satisfy requirements from insurers and institutional investors on larger-scale projects. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HS210R-120TC-D-Cosmos-570W-5ceb872a3a0f.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +1.7 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +1.5 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +1.3 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -30 W, lighter, +1.3 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | -30 W, lighter, +1.3 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | -25 W, lighter, +1.2 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | -25 W, lighter, +1.1 pp | | [Horay Solar HS550TC-MHB](https://comparepv.com/panel/horay-solar-hs550tc-mhb) | 550 W | -20 W, lighter, -0.9 pp | | [Horay Solar HS550TC-MHC-D](https://comparepv.com/panel/horay-solar-hs550tc-mhc-d) | 550 W | -20 W, -0.8 pp | | [Horay Solar HS555TC-MHB-D](https://comparepv.com/panel/horay-solar-hs555tc-mhb-d) | 555 W | -15 W, -0.7 pp | | [Horay Solar HS555TC-MHC-D](https://comparepv.com/panel/horay-solar-hs555tc-mhc-d) | 555 W | -15 W, -0.6 pp | | [Horay Solar HS560TC-MHB-D](https://comparepv.com/panel/horay-solar-hs560tc-mhb-d) | 560 W | -10 W, -0.5 pp | | [Horay Solar HS560TC-MHC-D](https://comparepv.com/panel/horay-solar-hs560tc-mhc-d) | 560 W | -10 W, -0.4 pp | | [Horay Solar HS565TC-MHB-D](https://comparepv.com/panel/horay-solar-hs565tc-mhb-d) | 565 W | -0.3 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +80 W, lighter, +2.1 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +75 W, lighter, +1.9 pp | --- Source: https://comparepv.com/panel/horay-solar-hs570tc-mhc-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.
