The 132-cell rectangular R-type cell layout (182 mm format) maximizes active area utilization, delivering up to 590 Wp in a standard-footprint frame. - **N-type TOPCon - zero LID** - N-type cells exhibit near-zero light-induced degradation (LID ≈ 0%) and a lower temperature coefficient than PERC (~-0.30%/°C vs ~-0.35%/°C for PERC), translating into a measurably higher annual energy yield - estimated 3-5% gain on hot summer days (NOCT >45°C). - **Bifacial + dual glass construction** - A bifaciality factor typical of TOPCon (≥80%) enables additional rear-side generation from reflected irradiance - in Polish conditions (snow, light gravel, bright facades) this adds an estimated 5-15% annual energy bonus. Dual glass eliminates backsheet delamination risk and improves moisture resistance (PID, busbar corrosion). - **BNEF Tier 1 certified (Q1 2026)** - Horay Solar has maintained BloombergNEF Tier 1 status from at least Q1 2025 through Q1 2026, confirming manufacturer bankability - a prerequisite for project financing, favorable insurance terms, and qualification in most commercial tender specifications. - **30-year linear power warranty** - The module carries a 30-year linear power warranty, consistent with the top-tier segment standard. This eliminates the 'cliff degradation' effect seen in older stepped warranties and simplifies LCOE calculations. For comparison, legacy PERC modules typically offered 25-year warranties. ## Cons - **Series discontinued** - The HS 199R-132 TC-D Delta series has discontinued status. This means no guaranteed supply continuity for replacement modules, increased risk of power mismatch in strings after partial damage, and potentially limited warranty support - manufacturers typically do not maintain spare inventory for discontinued product lines. - **Product warranty only 15 years** - The product (workmanship) warranty is 15 years, whereas leading premium-segment manufacturers (JinkoSolar Tiger Neo, LONGi Hi-MO 6, Trina Vertex N) now offer 25 years as standard. For bank-financed commercial installations, a 15-year product warranty may require additional insurance coverage or could be a disqualifying factor in procurement tenders. ## About this series The Horay Solar HS 199R-132 TC-D Delta photovoltaic module series represents a breakthrough in energy efficiency thanks to the use of **N-Type TOPCon cells**, which minimize energy losses and offer a significantly better temperature coefficient than standard solutions. What particularly sets this line apart is its **bifacial technology with double glass**, allowing for energy generation from reflected radiation as well, which clearly increases annual electricity production in Polish climatic conditions. The use of innovative R-type rectangular cells allows for better utilization of the module surface, effectively solving the problem of limited space on the roofs of single-family houses and commercial buildings. Unlike older generation products, the Delta series features **minimal light-induced degradation**, which provides investors with financial stability and predictability of yields for decades. Exceptional **resistance to extreme mechanical loads** and excellent structural tightness make these panels dedicated to the most demanding users who expect premium technology. Thanks to the combination of high bifaciality and modern silicon architecture, this series outperforms the competition in terms of yield per square meter, forming the foundation for modern and highly profitable photovoltaic systems. ## Notable figures - Efficiency of 22.4% matches the \*\*N-type 550-600W\*\* median - Power density of 222.5 W/m² matches the \*\*N-type 550-600W\*\* median - At -0.28%/°C, hot weather performance is typical for \*\*N-type 550-600W\*\* panels - At 31.5 kg (1.2 kg above \*\*N-type 550-600W\*\* median of 30.3 kg), requires checking roof load capacity - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface ## Questions ### Is the Horay Solar HS 199R-132 TC-D Delta series still available for purchase? The HS 199R-132 TC-D Delta series has been discontinued and is no longer actively manufactured by Horay Solar. Some distributors may still carry residual stock, but availability is limited. Before purchasing, confirm current inventory with your supplier and consider evaluating newer Horay Solar series that offer comparable or superior specifications. ### What warranty does the Horay Solar HS 199R-132 TC-D Delta come with? The manufacturer provides a 15-year product warranty covering material and workmanship defects. In addition, a 30-year linear power warranty guarantees predictable performance degradation over three decades. The dual-glass bifacial construction reduces delamination risk, which positively impacts long-term reliability in temperate and humid climates. ### What does the TC-D Delta designation mean and how does it differ from standard monofacial modules? TC-D stands for TOPCon dual glass, and Delta refers to the rectangular R-type cell layout optimized for higher surface coverage. Unlike conventional monofacial modules, the Delta series harvests energy from both sides thanks to its bifacial design. With a reflective ground surface, this can boost annual energy yield by several percentage points compared to single-sided panels of equal rated power. ### What is the peak power output of the HS 199R-132 TC-D Delta and is it enough for a residential home? The module reaches a maximum power of 590 Wp, placing it firmly in the high-power premium segment. A typical single-family home consuming 4,000-5,000 kWh annually usually requires 8-12 panels, resulting in a system size of roughly 4.7-7.1 kWp. The high per-panel wattage reduces the total number of modules needed, which is a key advantage on roofs with limited usable area. ### How do the Horay Solar HS 199R-132 TC-D Delta panels perform in cold or overcast conditions? N-type TOPCon cells offer a superior temperature coefficient compared to standard PERC technology, meaning lower losses at high temperatures and reliable output in cold weather. The bifacial dual-glass construction allows the rear side to capture energy reflected off snow cover, which is a meaningful real-world benefit during late-winter and early-spring months in central European climates. ### Are the HS 199R-132 TC-D Delta modules suitable for ground-mounted systems or carports where rear-side irradiance matters? Yes, ground mounts and carports are among the most effective use cases for this series. When elevated above the ground, the rear glass collects irradiance reflected from grass, concrete, or light-colored gravel, increasing overall energy harvest. The dual-glass construction also delivers high resistance to moisture ingress and mechanical loads, which is critical for freestanding structures exposed to higher wind pressure. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/HS199R-132TC-D-Delta-590W-25c98819b80e.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.4 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | -25 W, 15 kg lighter, +2.0 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -35 W, lighter, +2.0 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | -35 W, lighter, +2.0 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | -30 W, lighter, +1.9 pp | | [AIKO AIKO-A625-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a625-mah72dw) | 625 W | +50 W, cooler, +1.8 pp | | [Horay Solar HS570TC-MHO](https://comparepv.com/panel/horay-solar-hs570tc-mho) | 570 W | Lighter, -0.3 pp | | [Horay Solar HS580TC-MHD-D](https://comparepv.com/panel/horay-solar-hs580tc-mhd-d) | 580 W | +0.2 pp | | [Horay Solar HS585TC-MHO-D](https://comparepv.com/panel/horay-solar-hs585tc-mho-d) | 585 W | +10 W, +0.2 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +75 W, lighter, +2.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +70 W, lighter, +2.6 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +65 W, lighter, +2.4 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +60 W, lighter, +2.2 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +55 W, cooler, +2.0 pp | --- Source: https://comparepv.com/panel/horay-solar-hs575tc-mhd-d Not in this file, on the page: a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
