The Draco Module Series (N-TOPCon High Efficiency 96-16BB-W-WG) was designed for maximum energy yield in real-world installation conditions-including under weaker sunlight and higher temperatures. The use of N-TOPCon cells minimizes power degradation over time and ensures more stable performance compared to many P-type modules, translating to more predictable energy production over the long term. The construction featuring multiple 16BB string busbars improves current flow within the cell and supports higher operational reliability under working loads. The glass-glass variant enhances resistance to environmental factors, making it an ideal choice for investors in humid areas, wind-prone locations, or regions with intense UV exposure. The bifacial version of Draco effectively utilizes reflected light from the ground, making it particularly suitable for flat rooftops, carports, and ground-mount systems. This is the ideal choice for businesses, agriculture, and demanding clients seeking durability, high efficiency, and a reliable yield-rather than marketing promises.

What owners get
Low power degradation via N-TOPCon

N-type TOPCon cells deliver less than 1% first-year degradation and a linear 0.4% annual decline over 30 years, corresponding to a guaranteed 87.4% of nominal power at year 30 - a stronger profile than typical P-type PERC modules.

16BB layout improves reliability

The 16-busbar half-cut cell design improves current collection, reduces resistive losses, and lowers the risk of hot-spots, resulting in better resistance to mechanical stress and partial shading.

Bifacial glass-glass with POE encapsulant

Dual-glass construction with POE encapsulation provides strong anti-PID performance and resistance to moisture and UV exposure, while cell bifaciality above 80% enables up to 30% additional rear-side energy yield - a clear advantage for flat roofs, carports, and ground-mount installations.

Efficiency on par with segment leaders

The series' top-end efficiency (23.02%) matches the best comparable model - SunKean SKT440~460M12-96D4 (23.02%) - and exceeds DMEGC INFINITY RT (23%) and Axitec AXIbiperfect GR WB (22.54%) at the same 460 Wp maximum power.

BNEF Tier 1 status and bankability

Phono Solar has held BNEF Tier 1 status for nine consecutive years, including after the 2026 threshold increase from 5MW to 10MW, easing project financing through banks and institutional investors for series built on this platform.

Trade-offs
15-year product warranty lags market trend

Despite a 30-year power warranty, the product/workmanship warranty is limited to 15 years, while several Tier-1 manufacturers now offer 25-year product warranties matched to their power warranties - increasing investor risk exposure for component failures in the second half of the system's lifespan.

Lower-power variants trail peers on efficiency

The series' lowest efficiency variant (22.02%, 440 Wp) trails comparable modules at the same maximum power by about 1 percentage point versus DMEGC INFINITY RT (23%) and SunKean SKT440~460M12-96D4 (23.02%), potentially requiring more panels to reach equivalent system capacity on space-constrained roofs.

About the Draco Module Series (N‑TOPCon High Efficiency 96‑16BB‑W‑WG) series

6 answered

These answers cover the whole series. Where a figure differs, the specification above is this module's own.

What warranty does the Phono Solar Draco N-TOPCon 96-16BB series come with?
The Draco N-TOPCon 96-16BB series includes a 15-year product warranty covering material and manufacturing defects, and a 30-year linear power output warranty. Phono Solar guarantees first-year degradation of no more than 1% and no more than 0.4% per year thereafter, ensuring at least 87.4% of rated power after 30 years of operation.
How does N-TOPCon technology in the Draco series compare to standard PERC panels?
N-TOPCon cells use a thin tunnel oxide passivation layer on an N-type silicon base, virtually eliminating the Light Induced Degradation (LID) common in PERC and P-type cells. In practice, this means slower power degradation over the full 30-year warranty period, better performance at higher operating temperatures, and module efficiencies exceeding 22%.
Is the Phono Solar Draco 460 Wp bifacial glass-glass panel a good choice for flat roofs or carports?
Yes, the bifacial glass-glass variant is particularly well-suited for flat roofs and carports. The rear glass allows reflected albedo light to generate additional power, typically yielding a 5-15% energy bonus depending on the surface below. The dual-glass construction also improves resistance to moisture and UV exposure, which is critical for ground-mounted and open-air installations.
What advantage do 16 busbars (16BB) offer over older panels with 9 or 12 busbars?
More busbars shorten the current path across the cell, reducing internal resistance and heat losses. In the Draco 16BB series, this translates to higher cell efficiency, improved resistance to microcracks under mechanical stress from wind and snow loads, and a lower risk of hotspot formation under partial shading conditions.
Do the Draco N-TOPCon 96-16BB panels perform well in low-light conditions like overcast days?
Yes. N-TOPCon cells have a superior spectral response to diffuse light compared to conventional P-type modules. The Draco series is engineered for low-irradiance performance, meaning it generates proportionally more energy on cloudy mornings and during autumn months than older PERC modules with similar STC peak power ratings.
Is Phono Solar a reliable manufacturer and is the Draco series still available?
Phono Solar is a Chinese manufacturer classified as Tier 1 by Bloomberg NEF, reflecting bankable financials and a long market track record. The Draco N-TOPCon 96-16BB bifacial glass-glass series at up to 460 Wp is currently in production and not discontinued. Availability through European and Polish distributors is active - confirm lead times directly with your supplier.
