Super Multi Busbar (SMBB) technology further reduces internal resistance losses and lowers susceptibility to microcracks over the module's service life. - **Bifacial design - rear-side energy gain** - All five variants in the Delta series are bifacial modules, generating power from both the front and rear surfaces. On installations with high-albedo substrates (gravel, white roofing membrane, concrete) or tracker-mounted arrays, bifacial gain typically reaches 10-20% above nameplate power, improving the project's economic return without increasing the mounting footprint. - **30-year linear power warranty** - Horay Solar backs the Delta series with a 30-year linear power output warranty - longer than the 25-year standard offered by direct peers including ZNShine (ZXM7-UHLD120 Series). A longer power warranty horizon reduces investor risk and improves LCOE calculations on projects structured around long-term debt-service schedules. - **BNEF Tier-1 bankability confirmed Q1 2026** - Horay Solar maintained its BloombergNEF Tier-1 PV Module Manufacturer status on the Q1 2026 list. BNEF Tier-1 bankability is a prerequisite for institutional project financing in most markets, making the Delta series eligible for credit-backed residential installs and larger commercial PV projects requiring third-party financing. ## Cons - **Efficiency below peer-group leader** - The Delta series tops out at 23% module efficiency, while the directly comparable Gokin GK-5-54HG and GK-5-54HGb achieve 24.3% at the same 485 Wp peak power - a gap of 1.3 percentage points equates to roughly 5-6% greater module area required for equivalent installed capacity. On space-constrained rooftop installations this translates to measurable lost power output per available square meter compared to the Gokin offering. - **15-year product warranty** - The Delta series carries only a 15-year materials-and-workmanship warranty, whereas leading N-type TOPCon competitors - JinkoSolar Tiger Neo, LONGi Hi-MO 6, and Trina Vertex N - provide 25-year product warranties as standard. This means the final 15 years of the 30-year power guarantee period are not covered by product warranty, increasing long-term replacement-cost risk for the system owner. ## About this series The innovative Horay Solar Delta series of photovoltaic panels focuses on maximizing yields from limited roof space through the use of modern **N-type TOPCon cell** technology. This solution effectively eliminates the problem of light-induced degradation (LID) and guarantees exceptional performance even on cloudy days, which is crucial in the Polish climate zone. These modules are characterized by **high energy conversion efficiency**, achieved through the use of high-density cell packing and SMBB technology, which shortens the current flow path and minimizes resistive losses. The Delta series was designed for investors seeking uncompromising durability, as confirmed by **increased resistance to extreme mechanical loads**, such as strong winds or heavy snow. For owners of single-family homes, the aesthetic design will be key, while for the commercial sector, the low temperature coefficient will prove decisive, ensuring stable operation on hot days. By choosing these panels, you gain a **longer warranty period for power output**, which directly translates into a faster return on investment and greater financial security for years to come. This is an optimal choice for prosumer installations, where every watt of power obtained from a square meter of mounting surface counts. ## Notable figures - Module efficiency of 22.0% is 0.5pp below average for \*\*N-type 450-500W\*\* panels (median: 22.5%) - Power density of 220.2 W/m² is 5.1 W/m² below \*\*N-type 450-500W\*\* median (225.3 W/m²) - needs more roof space - At -0.28%/°C, hot weather performance is typical for \*\*N-type 450-500W\*\* panels - At 26.0 kg, this panel is 2.3 kg heavier than the \*\*N-type 450-500W\*\* median (23.7 kg) - more demanding for installation crews - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What warranty comes with Horay Solar Delta panels? Horay Solar Delta panels include a 15-year product warranty covering material and workmanship defects, and a 30-year linear power output warranty. The manufacturer guarantees a minimum energy yield over three decades - one of the longer warranty terms in the premium module segment - providing strong financial security and a more predictable return on investment. ### What is N-type TOPCon technology and why was it chosen for the Delta series? TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell technology that uses a thin silicon oxide interlayer to passivate the cell surface and eliminate Light-Induced Degradation (LID). Compared to standard PERC cells, it delivers higher conversion efficiency and lower first-year power loss. The Delta series reaches a maximum power of 485 Wp by combining TOPCon with SMBB busbar design, which shortens the current path and reduces resistive losses. ### Are Horay Solar Delta panels bifacial, and how does that affect my energy yield? Yes, the Delta series is bifacial - the modules generate electricity from both direct irradiance on the front side and reflected light captured on the rear. On rooftops with light-colored membranes or ground-mounted systems with bright substrates such as gravel or white TPO, the additional bifacial gain typically ranges from a few to over ten percent compared to a monofacial module with the same 485 Wp nameplate power. ### Will the Delta 485 Wp panels work on the limited roof space of a single-family home? Yes. The high per-panel power of 485 Wp means you need roughly 21 modules for a 10 kWp system instead of 25-30 with older technologies - a significant advantage on small or irregularly shaped roof sections. The Delta series also features reinforced resistance to mechanical loads from wind and snow, making it well suited to Polish climatic conditions. ### How do Horay Solar Delta panels perform on hot days - do they lose significant power? All PV panels lose some power at elevated temperatures, but N-type TOPCon cells used in the Delta series have a lower temperature coefficient than standard PERC technology. This means less power loss on hot days - relevant in Poland, where rooftop surface temperatures can exceed 60°C in summer - resulting in higher annual energy yields during the peak generation season. ### Is Horay Solar a reliable manufacturer to trust with a 30-year power warranty? Horay Solar holds Tier 1 manufacturer status, a designation awarded by independent financial institutions to suppliers with documented financial stability and consistent production quality. This matters because a 30-year power output warranty is only as valuable as the manufacturer's ability to honor it. The company is headquartered in China, which is standard for leading global PV module producers. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HS199R-108TC-D-Delta-485W-912538dbd803.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-54HJD-510M](https://comparepv.com/panel/longi-lr7-54hjd-510m) | 510 W | +45 W, cooler, +3.0 pp | | [AIKO AIKO-A495-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a495-mce54mw) | 495 W | +30 W, lighter, +2.8 pp | | [Longi Solar LR7-54HJD-505M](https://comparepv.com/panel/longi-lr7-54hjd-505m) | 505 W | +40 W, cooler, +2.7 pp | | [WINAICO WST-505BKX54-A2](https://comparepv.com/panel/winaico-wst-505bkx54-a2) | 505 W | +40 W, cooler, +2.7 pp | | [AIKO AIKO-A490-MCE54Mw](https://comparepv.com/panel/aiko-aiko-a490-mce54mw) | 490 W | +25 W, lighter, +2.5 pp | | [Longi Solar LR7-54HJD-500M](https://comparepv.com/panel/longi-lr7-54hjd-500m) | 500 W | +35 W, cooler, +2.5 pp | | [Talesun CIPRO-TN9C54M-500W](https://comparepv.com/panel/talesun-cipro-tn9c54m-500w) | 500 W | +35 W, lighter, +2.5 pp | | [Horay Solar HS470TC-MHD-D](https://comparepv.com/panel/horay-solar-hs470tc-mhd-d) | 470 W | +0.3 pp | | [Horay Solar HS475TC-MHD-D](https://comparepv.com/panel/horay-solar-hs475tc-mhd-d) | 475 W | +10 W, +0.5 pp | | [Horay Solar HS480TC-MHD-D](https://comparepv.com/panel/horay-solar-hs480tc-mhd-d) | 480 W | +15 W, +0.7 pp | | [Horay Solar HS485TC-MHD-D](https://comparepv.com/panel/horay-solar-hs485tc-mhd-d) | 485 W | +20 W, +1.0 pp | --- Source: https://comparepv.com/panel/horay-solar-hs465tc-mhd-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.
