The BYD AURO MLTK-36 series introduces a new level of quality in power density thanks to the use of p-type cell technology in the modern M10 format. This solution effectively eliminates the problem of limited installation space, allowing for a significantly higher energy yield from every square meter of the roof. Engineers focused on minimizing resistive losses through an advanced multi-busbar system, which translates into more stable module operation even on hot days. Thanks to the precise half-cut design, these panels handle partial shading exceptionally well, which is a key advantage in dense building environments. This series is dedicated to users seeking the highest durability, guaranteed by outstanding resistance to PID degradation and a construction that withstands extreme snow loads. Compared to the competition, BYD AURO MLTK-36 stands out for its attention to the optimization of the internal connection system, thereby offering an excellent temperature coefficient. It is an ideal choice for investors who value a fast return on investment and a reliable source of clean energy for decades, as confirmed by rigorous quality tests.

What owners get
Max. efficiency of 21.48% — top of segment

A peak efficiency of 21.48% places the series just behind the JA Solar DEEP BLUE 3.0 (21.5%) and clearly above the ET Solar Elite PLUS (21.4%) and Boviet VEGA (21.3%). This translates to higher energy yield from limited roof space with no price premium for newer N-type technology.

Favorable temperature coefficient

The datasheet (v202408A, BYD) specifies a Pmax TC of -0.332%/°C, which outperforms the -0.35%/°C of the JA Solar DEEP BLUE 3.0 in the same segment class. The 0.018 percentage-point difference equates to approximately 0.9 W/kWp less power loss at a typical summer module operating temperature of +75°C.

Bifacial design — up to 30% rear-side yield gain

According to the manufacturer's datasheet, the bifacial construction enables up to 30% additional energy harvest from reflected irradiance. This is particularly valuable in ground-mounted systems over high-albedo surfaces (sand, concrete, snow) or rooftops with TPO/PVC membranes.

Mechanical load rating of 5,400 Pa (front)

A front-side snow and wind load rating of 5,400 Pa corresponds to approximately 550 kg/m², more than twice the minimum IEC 61215 requirement of 2,400 Pa. The series is recommended for installations in snow load zones III–IV per PN-EN 1991-1-3.

BNEF Tier-1 manufacturer — investment bankability

BYD appears on the BNEF Tier 1 list (methodology updated March 2026), satisfying the requirement of having a minimum of 6 projects >10 MW financed by independent commercial banks. This status is critical for securing bank financing or leasing arrangements for commercial and utility-scale installations.

Trade-offs
PERC technology instead of N-type TOPCon

The series is based on p-type PERC cells, which exhibit a higher light-induced degradation (LID) rate compared to N-type TOPCon. The market is shifting en masse toward TOPCon in this power class: for example, the JA Solar DEEP BLUE 4.0 Pro (N-type TOPCon, up to 22.4% efficiency, TC = -0.30%/°C) is entering the same price segment in 2025–2026, offering superior linear degradation performance and lower temperature losses.

Notes from the database
  • At 20.5% efficiency, this panel is on par with typical PERC 500-550W modules
  • 205.2 W/m² power density is 3.8 W/m² below PERC 500-550W median (209.0 W/m²) - requires larger installation area
  • At -0.33%/°C, hot weather performance is typical for PERC 500-550W panels
  • 27.0 kg weight - 1.4 kg lighter than PERC 500-550W median (28.4 kg), reducing installation effort
  • Bifacial design (70% factor) captures reflected light - adds 4-10% yield on ground-mount or white roof

Common questions

6 answered
Are the BYD AURO MLTK-36 panels bifacial, and what does that mean in practice?
Yes, the BYD AURO MLTK-36 series consists of bifacial modules. This means the rear surface of the panel absorbs light reflected from the ground or mounting surface — such as a light-colored roofing membrane, gravel, or snow. Under favorable conditions, the rear-side gain can reach 20–30% compared to a monofacial module, effectively increasing annual energy yield without requiring additional roof area.
What warranty does the BYD AURO MLTK-36 series carry?
BYD provides a 12-year product warranty on the AURO MLTK-36 series, covering material defects and workmanship. This is complemented by a 25-year linear power output warranty — the manufacturer guarantees that after 25 years of operation the panel will retain at least 84.8% of its nominal power. First-year degradation does not exceed 2%, with a maximum annual degradation of 0.55% in subsequent years.
Do the BYD AURO MLTK-36 panels perform well under partial shading, for example from a chimney?
Yes. The MLTK-36 series employs half-cut cell technology, in which 144 cells are bisected. As a result, shading on part of the module limits losses only in the shaded area rather than across the entire string. In addition, the multi-busbar system minimizes internal resistance, so an installation on a roof with a chimney, dormers, or an antenna performs more efficiently than conventional 72-cell modules would under the same conditions.
How large and heavy are the BYD AURO MLTK-36 panels — will they fit on a typical gable roof?
The BYD AURO MLTK-36 (555 Wp) measures 2278 × 1134 × 35 mm and weighs approximately 27 kg. This is standard for M10-format modules at this power class. On a typical gable roof with a usable surface of 30–40 m², approximately 10–12 modules can be installed, yielding a system in the 5–6 kWp range. Before purchasing, it is advisable to have the installer conduct a roof audit, especially if the roof surface has an irregular shape.
Does the BYD AURO MLTK-36 series perform well during Polish winters and overcast weather?
The MLTK-36 panels operate across a temperature range of −40 °C to +85 °C, so Polish winters pose no risk to the modules whatsoever. PERC technology improves sensitivity to diffuse irradiance, which is characteristic of overcast days. The favorable temperature coefficient of Pmax at −0.332%/°C also means that on hot summer days the module loses less power than older cell designs.
Is BYD a reliable panel manufacturer, and is the AURO MLTK-36 series still available?
BYD (Build Your Dreams) is a Chinese corporation listed on Bloomberg NEF's Tier 1 ranking and one of the world's largest manufacturers of photovoltaic cells and modules. The company holds IEC 61215, IEC 61730, and TÜV certifications, and its products are available in Poland through authorized distributors. The AURO MLTK-36 series is an active product line and remains available for purchase.
