The extended warranty horizon improves project bankability and lowers LCOE in financial modeling. - **210 mm format - high unit power and lower BoS costs** - 210 mm silicon wafers enable unit power up to 580 Wp per module, translating to approximately 8-10% fewer mounting points, shorter DC wiring runs, and reduced racking costs per MWp compared to typical 182 mm modules rated at 460-490 Wp. - **BNEF Tier-1 bankable status (Q1 2026)** - Horay Solar has been listed on the BloombergNEF Tier-1 Module Manufacturers list since at least Q1 2025, with confirmed status maintained in Q1 2026. This classification is a prerequisite for bank-financed solar farms and PPA contracts with financial institutions across Europe. - **Bifacial glass-glass - rear-side energy yield** - The bifacial double-glass construction generates an additional 8-22% energy yield from reflected albedo - in line with independent CGC Sanya field tests for TOPCon bifacial modules. The benefit is particularly significant in the target agrivoltaic application, where light-colored vegetation raises the ground albedo coefficient. ## Cons - **Efficiency below direct peers** - The Galaxy series peaks at 22.2% efficiency (580 Wp variant), while both peer comparables reach 22.44-22.45% at the same power class: Emmvee Titanium Clear/Duo at 22.45% and ZNShine ZXM7-UHLD144 at 22.44%. The ~0.24-0.25 pp gap translates into a larger required roof or field area per megawatt of installed capacity. - **Product warranty of only 15 years** - The manufacturer offers a 15-year product warranty (material defects, mechanical damage) versus the 25-year standard applied by leading Tier-1 peers in the premium segment - including Trina Solar Vertex N, JA Solar DeepBlue 4.0 Pro, and LONGi Hi-MO X6. The shorter term may limit module acceptance by banks financing projects with an operational horizon exceeding 20 years. ## About this series The Horay Solar HS 210-110 TC-D Galaxy photovoltaic module series utilizes the most advanced **N-type TOPCon cell technology** currently on the market, which ensures higher conversion efficiency and excellent performance in low-light conditions.

The HS 210-110 TC-D Galaxy delivers a peak output of 580 Wp. TC-D in the model designation stands for TOPCon Double glass, indicating N-type TOPCon cell technology combined with a dual-glass module construction. The series uses 110 cells based on 210 mm silicon wafers, yielding high per-module power that directly reduces BoS costs - cabling, racking, and labor - in large-scale utility installations. ### How much additional energy does the bifacial design of the Galaxy panels generate in a typical installation? The bifacial structure of the Galaxy series captures reflected irradiance through the rear glass panel, adding 5-25% extra yield depending on ground surface albedo. On grassy agrivoltaic fields, a realistic rear-side gain is 10-15%. Light gravel or sandy ground produces even higher gains. The double glass construction protects the rear surface from moisture ingress, preserving bifacial performance throughout the full 30-year service life. ### What warranties does Horay Solar provide for the Galaxy HS 210-110 TC-D series? Horay Solar backs the Galaxy series with a 15-year product warranty covering material and workmanship defects, and a 30-year linear power output warranty. N-type TOPCon technology eliminates LID and LeTID degradation, keeping annual power loss at or below 0.4% after year one. This makes the 30-year power guarantee a credible long-term commitment. Horay Solar's Tier 1 manufacturer status provides additional confidence in warranty fulfillment. ### Are the Horay Solar Galaxy 580 Wp panels suitable for agrivoltaic farms? Yes - the HS 210-110 TC-D Galaxy is specifically engineered for agrivoltaic and large commercial applications. The double glass construction resists ammonia, moisture, and agrochemical exposure common in farming environments. The bifacial design maximizes yield over vegetated surfaces, and the 210 mm wafer format at 580 Wp reduces module count and infrastructure costs per MW of installed capacity, directly improving the project LCOE and ROI. ### Do the Galaxy TOPCon panels perform well in Poland's climate - during overcast days and winter freezes? Yes. N-type TOPCon cells deliver superior low-irradiance response compared to PERC, a meaningful advantage in Poland's variable-sunshine climate. The lower power temperature coefficient of -0.30%/°C (vs. -0.35%/°C for standard PERC) translates to better output on cold, sunny winter days. Elimination of LID ensures no power loss after extended system downtime during winter, so the plant returns to full rated output immediately after restart. ### Why choose TOPCon technology in the Galaxy series over less expensive PERC modules? TOPCon N-type cells in the Galaxy series provide higher conversion efficiency, better low-light performance, and a lower temperature coefficient (-0.30%/°C) compared to PERC (-0.35%/°C). The elimination of LID and LeTID degradation means the Galaxy module retains a higher percentage of its nameplate power after 30 years than a comparable PERC module. Despite a higher upfront cost, the lower LCOE and stronger long-term ROI make Galaxy the more economical choice for utility-scale and agrivoltaic PV projects. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HS210-110TC-D-Galaxy-580W-bf1ce513773a.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +3.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +3.0 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, 16 kg lighter, +2.8 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -25 W, lighter, +2.8 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | -25 W, lighter, +2.8 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | Cooler, lighter, +2.7 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +2.6 pp | | [Horay Solar HS560TC-MHG-D](https://comparepv.com/panel/horay-solar-hs560tc-mhg-d) | 560 W | -0.2 pp | | [Horay Solar HS570TC-MHG-D](https://comparepv.com/panel/horay-solar-hs570tc-mhg-d) | 570 W | Very close match | | [Horay Solar HS575TC-MHG-D](https://comparepv.com/panel/horay-solar-hs575tc-mhg-d) | 575 W | +10 W, +0.4 pp | | [Horay Solar HS580TC-MHG-D](https://comparepv.com/panel/horay-solar-hs580tc-mhg-d) | 580 W | +15 W, +0.6 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +115 W, lighter, +3.6 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +110 W, lighter, +3.4 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +135 W, cooler, +3.4 pp | | [WINAICO WST-675BKX72-A2](https://comparepv.com/panel/winaico-wst-675bkx72-a2) | 675 W | +110 W, cooler, +3.4 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +130 W, cooler, +3.3 pp | --- Source: https://comparepv.com/panel/horay-solar-hs565tc-mhg-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.
