Strong in heat, no clear weak spot
The BYD AURO N NLBK-36 (570-600W) series are modules designed to maximize energy yield from the same surface area - particularly in situations where every square meter of roof space or limited ground space is valuable. A key advantage is the combination of N-type TOPCon cell technology with a bifacial design, which allows for efficient operation even with reflected light and better utilization of site conditions (bright ground, gravel, roof membrane). These modules are characterized by low temperature sensitivity, ensuring stable production even in hot weather, as well as long-term durability and slower degradation - which is a significant advantage for investments planned over decades. Furthermore, a sealed connection box with high IP protection is used, which contributes to reliability in more challenging weather conditions. This is an excellent choice for commercial, industrial, and large residential installations, where high production, durability, and predictable returns are the top priorities.
Ranking
Signals from the data
Residential, commercial, utility-scale and hot-climate.
Top 1% of the TOPCon 550-600 W segment, against a median of -0.290. Ranked 1,295th in the whole database.
Top 5% of the TOPCon 550-600 W segment, against a median of 22.44%. Ranked 1,744th in the whole database.
Top 7% of the TOPCon 550-600 W segment, against a median of 224.4. Ranked 1,758th in the whole database.
The best variants in the series achieve 23.23% efficiency, placing them on par with the Lexron 144 CELL HALFCUT TOPCon (23.23%) and Tongwei TWMND N-type (23.2%), and significantly above the Talesun BISTAR TP7F78M (21.5%). This translates into meaningfully higher energy yield from the same installation footprint.
The temperature coefficient of Pmax is -0.30%/°C, which is more favorable than the typical -0.35%/°C for PERC modules. The guaranteed annual degradation does not exceed 0.4%, ensuring the module retains at least 87.4% of its nominal power after 30 years — a value confirmed in the official BYD AURO N datasheet.
The bifacial design with up to 80% bifaciality enables energy harvest from reflected irradiance off the ground surface (gravel, light-colored membrane, concrete), increasing annual yield by 5–15% depending on installation conditions. The benefit is especially significant in ground-mounted and rooftop systems with high-albedo surfaces.
BYD offers a 30-year linear power warranty (>87.4% after 30 years), while many manufacturers in this price segment cap their coverage at 25 years. This is a meaningful advantage in LCOE calculations for commercial and industrial projects planned across a full three-decade operational life.
BYD is listed on the BNEF Tier 1 PV Module Manufacturers ranking (confirmed Q1 2026), meaning banks and infrastructure funds recognize the manufacturer as financially credible. This facilitates project finance and reduces counterparty risk on large-scale installations.
The standard workmanship and materials warranty is 12 years, whereas JA Solar, Jinko Solar, and Trina Solar offer 25-year product warranties in comparable product classes. For installations with a planned service life of 25–30 years, this means that manufacturing defects detected after year 12 will not be covered under the manufacturer's warranty.
- Efficiency of 23.0% is 0.6pp above the TOPCon 550-600W median (22.4%)
- At 230.3 W/m² power density, this panel generates 5.9 W/m² more per unit area than TOPCon 550-600W median (224.4 W/m²)
- At -0.28%/°C, hot weather performance is typical for TOPCon 550-600W panels
- 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces
- Ranked #1744 out of 14005 panels for efficiency in the database
