## Pros

- **Efficiency exceeds direct peers** - 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.
- **Bifacial dual-glass boosts energy yield** - 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.
- **30-year power warranty with high threshold** - 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.
- **Tier-1 BNEF status since 2014** - 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.
- **Low temperature coefficient of -0.29%/°C** - 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.


## Cons

- **Efficiency trails newest 2026 series** - 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.
- **Base variants lag behind peer efficiency** - 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.


## About this series

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.


## Notable figures

- 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


## Questions


### What warranty does the Phono Solar Draco N-TOPCon 108-16BB-W-WG series carry?

The Phono Solar Draco N-TOPCon 108-16BB series comes with a 15-year product warranty and a 30-year linear power output warranty. The manufacturer guarantees first-year degradation below 1% and no more than 0.4% per year thereafter, ensuring at least 80% of rated power after 30 years. This places the Draco series among the strongest warranty tiers available in the premium residential and commercial PV segment.


### How does N-TOPCon cell technology in the Draco series compare to standard PERC cells?

N-TOPCon cells used in the Phono Solar Draco series deliver module efficiency above 22.5%, zero LID (Light Induced Degradation), and a lower annual degradation rate of 0.4% versus a typical 0.55% for PERC. In real-world terms this means higher lifetime energy yield, better low-irradiance performance, and more predictable output - a key advantage for prosumer net-metering settlements and commercial LCOE calculations.


### Does the bifacial design of the Phono Solar Draco 445W make sense for a pitched rooftop installation?

On a pitched roof, the bifacial gain from the Draco series is most pronounced over light-colored underlays or membranes where rear-side irradiance is meaningful. On dark roofing materials the benefit is minimal. The full bifacial potential - up to 30% additional rear-side yield per Phono Solar's datasheet - is realized in ground-mount or flat-roof applications with highly reflective surfaces.


### How fast do Phono Solar Draco 445W panels degrade over years of use?

The Draco N-TOPCon 108-16BB series is rated for less than 1% first-year degradation and a maximum linear degradation of 0.4% per year over 30 years, guaranteeing at least 80% of nameplate power at end of warranty. N-TOPCon technology also eliminates the LID effect that causes an irreversible post-illumination power loss in standard PERC modules.


### Is the dual-glass construction of the Draco series suitable for harsh climatic conditions?

Yes. The glass-glass design of the Phono Solar Draco series replaces the conventional rear EVA film with a second glass sheet, significantly reducing moisture ingress and improving resistance to corrosion, mechanical loads from wind and snow, and extreme temperature cycling. This is particularly relevant in continental climates where seasonal temperature swings can exceed 60°C, directly supporting long module service life.


### Is the Phono Solar Draco N-TOPCon 108-16BB-W-WG series currently available?

Yes, the Phono Solar Draco N-TOPCon 108-16BB-W-WG series is in active production and available through distribution channels. Phono Solar is a Bloomberg NEF Tier 1 manufacturer, ensuring stable module supply through authorized distributors across Europe. Contact your local distributor to confirm current stock levels and availability of specific wattage variants before placing an order.
