Double heat-strengthened glass mitigates microcracks, PID degradation risk, and moisture ingress - extending module service life beyond 30 years. - **Up to 23% efficiency - top of peer comparables** - The HS191R-144TC-D-Basin-620W variant reaches 23% module efficiency, matching direct competitors HT-SAAE HT66-18X(ND)-F (23%) and Weran Solar LR7-72HTH 595~620M (23%). For ground-mounted utility projects with land constraints, this translates to reduced BoS costs (cabling, racking, land lease) for the same nameplate capacity. - **30-year linear power output warranty** - Horay Solar guarantees a linear power degradation schedule over 30 years, consistent with the premium N-type TOPCon industry standard (≥87.4% of nameplate power at year 30). This enables stable financial modeling of PV farm revenues through approximately 2056 without exceeding contractual degradation thresholds. - **BNEF Tier-1 bankability confirmed** - Horay Solar has held BNEF Tier-1 manufacturer status since Q1 2025, confirmed again in the Q1 2026 ranking. Tier-1 classification is a prerequisite for most project-finance lenders and EU fund structures backing utility-scale PV assets, eliminating manufacturer-risk flags during due diligence. ## Cons - **Product warranty only 15 years** - The Basin series carries a 15-year product warranty (covering physical defects and lamination), while direct N-type TOPCon 600+ Wp competitors - including Trina Solar Vertex N, JA Solar DeepBlue 4.0 Pro, and Canadian Solar TOPBiHiKu6 - offer a standard 25-year product warranty. For a PV farm with a 20-25-year loan amortization schedule, this gap introduces real risk of out-of-warranty replacement costs. ## About this series The Horay Solar HS 191R-144 TC-D Basin series is an advanced solution based on **N-type TOPCon technology**, which redefines performance standards in challenging lighting conditions. Thanks to the **bifacial dual-glass** design, these panels not only generate additional energy from both sides of the module but also demonstrate extreme resistance to degradation caused by atmospheric factors. This solution effectively eliminates the problem of rapid power decline over time, making the investment significantly more financially predictable over the course of several decades. These modules are characterized by an excellent temperature coefficient, allowing them to maintain high efficiency even on hot days when traditional cells lose effectiveness. They are primarily intended for investors building **large-scale photovoltaic farms** and demanding commercial installations where the lowest levelized cost of energy (LCOE) is key. What sets them apart from the competition is the unique 144 TC-D cell structure, which minimizes internal losses and optimizes current flow inside the module. By choosing the Basin series, the user receives **maximum power density** per square meter and a guarantee of longevity, which is crucial in an era of dynamically changing energy prices in Poland. The use of dual glass further increases the structural rigidity, protecting the cells from micro-cracks. ## Notable figures - At 22.6% efficiency, this panel is on par with typical \*\*TOPCon 600-650W\*\* modules - Power density of 225.8 W/m² matches the \*\*TOPCon 600-650W\*\* median - At -0.28%/°C, hot weather performance is typical for \*\*TOPCon 600-650W\*\* panels - Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof - #3716 for efficiency, #1347 for temperature performance out of 14129 panels ## Questions ### What is the maximum power output of the Horay Solar HS 191R-144 TC-D Basin panel and what type of installation is it designed for? The panel reaches a peak power of 620 Wp, placing it among the most powerful modules currently available on the market. The Basin series is primarily engineered for utility-scale solar farms and large commercial installations where achieving the lowest possible LCOE is the primary objective. Its high power density delivers more energy output from the same ground or industrial rooftop area, directly shortening the investment payback period. ### What warranty does Horay Solar offer on the Basin series? Horay Solar provides a 15-year product warranty on the Basin series, covering material and manufacturing defects. In addition, the manufacturer guarantees linear power performance for 30 years, ensuring the module continues to operate at a defined minimum efficiency level throughout that period. This is among the longer power warranties available on the market and is critical both for ROI calculations on utility-scale solar farms and for securing project financing from banks. ### Is the HS 191R-144 TC-D Basin panel bifacial, and how much additional energy can it generate? Yes, the Basin series uses a bifacial dual-glass construction with tempered glass on both sides of the module. The panel generates electricity from both the front and rear faces by capturing light reflected from the ground surface (albedo effect). Depending on the ground cover type beneath the array, additional energy yield from the rear side typically ranges from 10 to 25%, directly reducing the system LCOE without increasing the cost of the modules themselves. ### How does the Basin series handle high temperatures on hot summer days? The N-type TOPCon technology used in the Basin series features a lower temperature coefficient than conventional PERC cells. This means that as module temperature rises, these panels lose proportionally less power compared to older technologies. This is especially important during summer peak hours, when traditional modules can lose over 10% of their rated output, while Basin modules maintain noticeably higher real-world energy yields under the same conditions. ### What is the 144 TC-D cell structure and how does it differ from standard solar panels? The designation 144 TC-D indicates the module contains 144 half-cut cells, which reduces internal resistance and minimizes thermal losses within the module. The letter D stands for dual-glass, meaning both sides are encapsulated with tempered glass instead of a standard polymer backsheet. This construction improves mechanical rigidity, eliminates the risk of cell microcracks, and significantly slows long-term module degradation, which is especially important under the cyclical thermal stress conditions typical of utility-scale solar farms. ### Is Horay Solar a Tier 1 manufacturer, and why does that matter when purchasing panels for a solar farm? Yes, Horay Solar holds Tier 1 status from independent industry rating agencies. Tier 1 classification means the manufacturer meets high financial stability and production quality standards, which significantly reduces investment risk in the context of long-term product and power warranties. For banks and investment funds financing utility-scale solar projects, Tier 1 certification is often a formal prerequisite for project loan approval, making the choice of a Tier 1 manufacturer a key factor in streamlining project financing. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HS191R-144TC-D-Basin-620W-5204e2df3d2b.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +40 W, lighter, +2.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +35 W, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -50 W, lighter, +2.2 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +30 W, lighter, +2.2 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +25 W, lighter, +2.0 pp | | [Longi Solar LR8-66HVD-660M](https://comparepv.com/panel/longi-lr8-66hvd-660m) | 660 W | +50 W, cooler, +1.8 pp | | [Horay Solar HS600TC-MHB](https://comparepv.com/panel/horay-solar-hs600tc-mhb) | 600 W | -10 W, lighter, -0.4 pp | | [Horay Solar HS605TC-MHB](https://comparepv.com/panel/horay-solar-hs605tc-mhb) | 605 W | Lighter, -0.2 pp | | [Horay Solar HS615TC-MHC-D](https://comparepv.com/panel/horay-solar-hs615tc-mhc-d) | 615 W | Very close match | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +70 W, lighter, +2.6 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +65 W, lighter, +2.4 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | +90 W, cooler, +2.4 pp | | [WINAICO WST-675BKX72-A2](https://comparepv.com/panel/winaico-wst-675bkx72-a2) | 675 W | +65 W, cooler, +2.4 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | +85 W, cooler, +2.3 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +60 W, lighter, +2.2 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +60 W, lighter, +2.2 pp | --- Source: https://comparepv.com/panel/horay-solar-hs610tc-mhb-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.
