Efficiency leader, no clear weak spot
The Phono Solar Draco Module Series (N-TOPCon HIGH EFFICIENCY 108-16BB-W-WG) was designed specifically to maximize energy yield from the same rooftop surface - particularly when conditions are not ideal. The use of N-TOPCon cells translates to higher operational stability and slower degradation over time, effectively reducing the risk of energy production decline in subsequent years. In practice, the user gains predictable energy output, which is crucial for domestic installations, commercial billing, and project planning.
The bifacial structure allows capturing additional energy from reflected light, which is significant on bright rooftops, roofing surfaces, and free-standing structures. Furthermore, the 16BB architecture minimizes internal losses and supports high efficiency during daily operation, while the dual-glass (glass-glass) design enhances resistance to moisture, temperature fluctuations, and mechanical stress.
This solution is ideal for premium residential installations, corporate rooftops, and projects where long lifespan and better performance under low irradiance and partial shading are key.

Signals from the data
Residential, commercial and shaded-installations.
Top 7% of the TOPCon 400-450 W segment, against a median of 22.00%. Ranked 4,041st in the whole database.
Top 8% of the TOPCon 400-450 W segment, against a median of 220.2. Ranked 4,158th in the whole database.
Peak efficiency of 22.79% surpasses leading bifacial TOPCon peer series - Jinko Tiger Neo 54HL4R-BDB (22.27%), Q-Cells Q.TRON BLACK (22.3%), and Astronergy ASTRO N7s (22.3%) - all at the same 445Wp peak power.
Glass-glass construction with bifaciality above 80% captures additional energy from reflected light - valuable on bright roofs and ground-mount installations - while improving moisture and mechanical-load resistance versus backsheet modules.
The manufacturer guarantees at least 87.4% of nominal power after 30 years of operation, providing predictable yields for prosumer settlements comparable to leading TOPCon series on the market.
Phono Solar (founded 2004) has been continuously listed on the Bloomberg NEF Tier-1 list since 2014, confirming financial stability and bankability for commercial project financing.
The -0.29%/°C rating limits power loss on hot days more effectively than typical PERC modules (usually around -0.35%/°C), supported by the 16BB architecture that reduces resistive losses within the cell.
Launched in 2022, and despite outperforming the direct peers listed in the context, the series' 22.79% peak efficiency now trails the newest TOPCon modules (Jinko Tiger Neo 3.0 - 24.0%, Trina Vertex S+ - 23.8%) and back-contact technology (Aiko NEOSTAR ABC - 25.0%) available on the market in 2026.
The entry-level 425Wp variant reaches only 21.76% efficiency - below comparable competitor series (22.27-22.3%). The full technological advantage is only realized with the top 445Wp/22.79% variant.
- 22.5% module efficiency - 0.5pp better than the TOPCon 400-450W median of 22.0%
- Power density of 225.3 W/m² packs 5.1 W/m² more into the same footprint vs TOPCon 400-450W median (220.2 W/m²)
- At -0.29%/°C, hot weather performance is typical for TOPCon 400-450W panels
- At 24.0 kg (2.0 kg above TOPCon 400-450W median of 22.0 kg), requires checking roof load capacity
- Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface
