The BYD AURO N NLTK-27 series is based on advanced N-type TOPCon cell technology, which sets new efficiency standards in the Polish solar energy sector. A key differentiator of this line is its exceptional resistance to LID and LeTID degradation, which guarantees users high power yields for many years without rapid efficiency drops. Thanks to the use of bifacial cell activity, these modules can efficiently process light reflected from the ground, significantly increasing the profitability of investments in agrivoltaic farms and commercial installations. They solve the problem of power loss at high temperatures because they feature an excellent temperature coefficient, working more efficiently in full sun than traditional solutions. This series is dedicated to demanding investors for whom maximum power density on limited roof space is a priority. Compared to the competition, BYD AURO N also stands out for its excellent performance in low light intensity, ensuring electricity production from the early morning hours. The use of SMBB technology with multiple busbars shortens the electron flow path, minimizing internal losses and increasing the mechanical resistance of the panels to micro-cracks, making them one of the safest choices on the market.

What owners get
Highest Efficiency Among Peer Comparables

The module achieves up to 22.79% conversion efficiency — outperforming the Q-Cells Q.TRON BLACK (22.30%), Solitek SOLRIF D Satin (22.06%), and SunEvo SE6-46SC (21.40%). On a 30 m² roof, the gap versus SunEvo translates to approximately 40 Wp of additional installed capacity.

Zero LID and Degradation <0.4%/Year

N-type TOPCon technology eliminates light-induced degradation (Zero LID) and guarantees annual power loss below 0.4%. Over a 25-year investment horizon, this delivers measurably higher cumulative energy yield than standard PERC modules (typically 0.55%/year), representing an estimated 3–4% more total energy produced.

Temperature Coefficient Pmax: -0.30%/°C

The -0.30%/°C rating is more favorable than the typical -0.35%/°C for PERC technology. Under Polish summer conditions (module temperature approximately 60–65°C, i.e., ~35°C above STC), the module loses approximately 3.0% of power rather than 3.5% — a noticeable difference in peak output during July and August.

Bifacial with Bifaciality Factor >80%

Bifacial cells enable 5–25% additional energy gain depending on ground albedo (white gravel ballast, light-colored roofing membrane, light concrete). Particularly relevant for ground-mount installations, agrivoltaic systems, and flat roofs with elevated racking.

BNEF Tier-1 Manufacturer with Strong Financial Stability

BYD (founded 1995) appears on the BNEF Tier-1 list for Q1 2026, confirming its bankability for project financing. Its diversified portfolio — spanning batteries, EVs, and industrial energy — significantly mitigates manufacturer insolvency risk over the 25-year power warranty horizon.

Trade-offs
12-Year Product Warranty — Market Minimum

A 12-year product warranty is the Tier-1 standard (on par with the Q-Cells Q.TRON BLACK in this segment), but premium manufacturers outside this tier offer substantially longer terms: REC Group 20 years, Panasonic EVERVOLT 25 years. For institutional investors with bankability requirements exceeding 15 years, this may be a compelling argument in favor of alternatives.

Common questions

6 answered
What warranty is provided for the BYD AURO N NLTK-27 panels?
The BYD AURO N NLTK-27 series comes with a 12-year product warranty covering manufacturing defects and material faults, along with a 25-year linear power output warranty. The manufacturer declares an annual degradation rate below 0.4%, meaning that after 25 years of operation the modules retain a significantly higher percentage of their nominal power output compared to older P-type technologies. The warranty is valid provided installation is carried out by a certified installer.
What is TOPCon technology in BYD AURO N panels, and is the premium for N-type worth it?
TOPCon (Tunnel Oxide Passivated Contact) is an N-type cell architecture featuring an additional passivation layer that drastically reduces charge carrier recombination. In practice, this translates to a higher module efficiency of up to 23.25% for the NLTK-27, zero LID (Light-Induced Degradation), and superior performance at elevated temperatures thanks to a temperature coefficient of -0.30%/°C. For rooftop and commercial installations, this results in more kilowatt-hours generated from the same surface area compared to standard PERC panels.
Does the bifacial design of the BYD AURO N NLTK-27 make sense on a conventional pitched roof?
Bifacial cells with a bifaciality factor above 80% deliver the greatest energy gain in ground-mounted and agrivoltaic installations, where reflected light from bright or grass-covered surfaces reaches the rear side of the module. On a dark pitched roof, this bifacial gain is minimal. Nevertheless, the NLTK-27 modules feature dual-glass construction that provides superior mechanical resistance to microcracks and extends service life, which justifies their selection even in residential prosumer installations.
How do the BYD AURO N NLTK-27 panels perform on cloudy days and in winter?
Thanks to N-type TOPCon technology, the NLTK-27 series delivers above-average power output under low irradiance conditions typical of mornings, evenings, and overcast skies. The low temperature coefficient of -0.30%/°C also means that on cold, sunny winter days the modules produce more power than they would during summer heat. This results in a better annual energy yield in the Polish climate compared to older P-type PERC cells.
Are the 445 Wp BYD AURO N NLTK-27 panels suitable for a small residential 10 kWp system?
Yes, 445 Wp modules allow a 10 kWp system to be built using only 23 panels, reducing the number of mounting points and the total cable run compared to lower-wattage models. The high efficiency of over 23% translates to a smaller roof footprint. BYD is a Tier 1 manufacturer with a well-established market presence, which simplifies servicing and module replacement if needed throughout the entire warranty period.
Is the BYD AURO N NLTK-27 series resistant to LID and LeTID degradation?
Yes, this is one of the key advantages of N-type TOPCon cells. LID (Light-Induced Degradation), which can reduce the output of P-type panels by 1–3% within the first months of operation, is virtually non-existent in the NLTK-27. The series also demonstrates resistance to LeTID (Light and elevated Temperature Induced Degradation), which is particularly relevant during summer when panels heat up under peak production conditions. The manufacturer guarantees an annual degradation rate below 0.4% throughout the entire 25-year power output warranty period.
