This secures LCOE projections across three full decades without the risk of a shortened performance guarantee period. - **Full-black aesthetics – architectural integration** - Black frame combined with a black backsheet eliminates contrasting silver hardware, a key differentiator for buildings subject to architectural review or premium residential projects. All-black modules are strongly preferred by end-customers in the upper single-family segment where rooftop appearance carries commercial value. - **Half-cut cells + multi-busbar** - Splitting cells in half reduces series resistance and limits power loss under partial shading, keeping output higher at non-ideal mounting positions (eaves, dormer windows). Multi-busbar technology shortens current paths and reduces micro-cracking during manufacturing, improving long-term mechanical reliability. ## Cons - **Not BNEF Tier-1 bankable** - KDM Kingdom Solar does not appear on the BNEF Tier-1 list (Q1 2026). The manufacturer reports ~1 GW annual production capacity – far below the de-facto BNEF threshold (non-recourse financing by ≥6 banks across ≥6 projects of ≥10 MW each). The absence of bankability limits the modules' suitability for PPA structures, insured lease/loan financing, and projects subject to lender technical due diligence. - **12-year product warranty – below market standard** - Leading N-type manufacturers now provide 25-year product warranties (JA Solar Deep Blue N, Jinko Tiger Neo for US/EU markets – confirmed by SurgePV Warranty Comparison 2026). KDM's 12-year coverage means any material defect or mechanical failure arising after year 12 falls outside warranty, shifting replacement costs to the system owner or insurer. - **22.07% efficiency vs. 23.0% peers** - At the same rated power of 570 Wp, both peer-comparable Horay Solar modules (HS 191R-132 TC Basin and TC-D Basin) achieve 23.0% module efficiency – a 0.93 pp advantage. On equivalent roof space, a Horay-based system would generate approximately 4.2% more energy, or allow a proportionally smaller array footprint for the same target system output. ## About this series The KDM Kingdom Solar MONO-FACIAL BLACK SOLAR MODULE panel series is an advanced solution based on **monocrystalline cells in half-cut technology**, which guarantee high efficiency even in less favorable lighting conditions. Thanks to the use of a **multi-busbar** system, these modules effectively minimize energy losses resulting from internal resistance and shading effects, which translates into stable yields throughout the year. It is an ideal choice for investors looking for a balance between aesthetics and performance. The elegant black finish makes the panels blend perfectly with modern architecture, eliminating the problem of conspicuous structural elements. **High resistance to PID degradation** and a reinforced mechanical structure effectively protect the installation against extreme weather phenomena, such as strong wind or snow loads. This series solves the problem of limited installation space by offering high power density per square meter. It is dedicated primarily to single-family homeowners and businesses for whom the priority is **maximum reliability and a fast return on investment**. Compared to the competition, these modules stand out for their exceptional thermal stability and rigorous quality control, which ensures peace of mind for decades of operation. ## Notable figures - At 22.1% efficiency, this panel is on par with typical \*\*N-type 550-600W\*\* modules - 220.8 W/m² power density is 3.8 W/m² below \*\*N-type 550-600W\*\* median (224.5 W/m²) - requires larger installation area - Temperature coefficient of -0.29%/°C matches the \*\*N-type 550-600W\*\* median - Weight of 28.0 kg (1.5 kg below \*\*N-type 550-600W\*\* median of 29.5 kg) allows easier transport and roof mounting - In the top 44% for efficiency among all N-type panels ## Questions ### What warranty does KDM Kingdom Solar MONO-FACIAL BLACK SOLAR MODULE come with? The manufacturer provides a 12-year product warranty covering defects in materials and workmanship, along with a 30-year linear power output warranty. This means the module is guaranteed to maintain a specified minimum power level for three decades. These terms are consistent with premium N-type cell technology, which typically delivers lower annual degradation rates than older PERC-based modules. ### What are the real-world benefits of N-type cell technology in the KDM MONO-FACIAL BLACK series? N-type cells exhibit lower annual power degradation (typically below 0.4% per year) and superior resistance to LID (Light Induced Degradation) compared to P-type PERC cells. For a 570 Wp module, this difference accumulates to a significant number of additional kilowatt-hours over the system's lifetime, effectively improving LCOE and shortening the payback period without any extra maintenance effort. ### Do the all-black KDM MONO-FACIAL BLACK panels run hotter than standard modules, and does this hurt output? Dark backsheet and frame finishes can marginally increase operating cell temperature under full irradiance. The MONO-FACIAL BLACK series offsets this through half-cut cell architecture and a multi-busbar layout, both of which reduce internal resistive losses at elevated temperatures. The temperature coefficient of Pmax for N-type cells is typically around -0.29%/°C — better than most P-type alternatives — so real-world losses are minimal. ### Are the KDM MONO-FACIAL BLACK 570 Wp panels suitable for a pitched residential roof? Yes, the series is specifically designed for residential single-family installations. At 570 Wp, these are large-format modules, so verifying the exact dimensions from the datasheet and confirming the roof's structural load capacity before installation is essential. The half-cut cell design improves tolerance to partial shading from chimneys or dormers, which is a common challenge on pitched residential rooftops. ### Is KDM Kingdom Solar a Tier 1 manufacturer, and is it a reliable choice? KDM Kingdom Solar is not currently listed on the Bloomberg NEF Tier 1 bankability ranking, which tracks manufacturers financed by project banks. This does not automatically indicate poor product quality — the brand offers N-type half-cut modules backed by a 30-year power warranty, signaling confidence in long-term performance. Before purchasing, it is advisable to verify the manufacturer's current financial standing and the availability of warranty service in your region. ### How does the KDM MONO-FACIAL BLACK series differ from bifacial panels, and when should I choose it? MONO-FACIAL BLACK modules generate electricity only from the front cell surface, unlike bifacial panels that also harvest light reflected off the ground through the rear side. This series is the better choice when panels are installed on dark roofing material with low albedo, or when visual aesthetics are a priority — the uniform all-black finish integrates seamlessly with modern architecture without the visible silver busbars typical of bifacial glass-glass modules. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/20250731134637_823-704f29cbd1be.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.7 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | Cooler, lighter, +2.5 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | Cooler, lighter, +2.3 pp | | [JA Solar JAT60S40-540/LR](https://comparepv.com/panel/ja-solar-jat60s40-540-lr) | 540 W | -30 W, lighter, +2.3 pp | | [Gokin GK-5-60HG-540M](https://comparepv.com/panel/gokin-gk-5-60hg-540m) | 540 W | -30 W, lighter, +2.3 pp | | [Jinko Solar JKM545-54QL6-DV-F1-EU](https://comparepv.com/panel/jinko-solar-jkm545-54ql6-dv-f1-eu) | 545 W | -25 W, cooler, +2.2 pp | | [Longi Solar LR7-60HVH-545M](https://comparepv.com/panel/longi-lr7-60hvh-545m) | 545 W | Cooler, lighter, +2.1 pp | | [KDM Kingdom Solar KD-M590-144-N](https://comparepv.com/panel/kdm-kingdom-solar-kd-m590-144-n) | 590 W | +20 W, +0.7 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +80 W, cooler, +3.1 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +75 W, cooler, +2.9 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +70 W, cooler, +2.7 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +65 W, cooler, +2.5 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +60 W, heavier, +2.3 pp | --- Source: https://comparepv.com/panel/kdm-kingdom-solar-kd-m570-144-n Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
