Middle of its segment, modest efficiency
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.
Ranking
Signals from the data
Residential, commercial and shaded-installations.
Tight roof space.
Bottom 24% of the N-type 550-600 W segment, against a median of 22.45%.
N-type cell technology delivers annual degradation of ~0.40%/year (vs ~0.55%/year for PERC) and a better temperature coefficient (~-0.30%/°C vs -0.35%/°C for PERC), translating into measurably higher energy yield during summer months and lower power loss over 30 years of operation.
The manufacturer guarantees module performance for 30 years, consistent with the current N-type TOPCon market standard (JA Solar Deep Blue N, Jinko Tiger Neo: 30 years, ≥87.4% rated output). This secures LCOE projections across three full decades without the risk of a shortened performance guarantee period.
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.
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.
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.
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.
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.
- 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
