The Draco series (launched 2022) remains in active production, ensuring continuity of supply and warranty service. - **16BB layout with dual glass and low temp. coefficient** - The 16-busbar layout reduces resistive losses, while a -0.29%/°C power temperature coefficient combined with dual-glass construction improves thermal resilience and mechanical durability in demanding industrial installations. ## Cons - **15-year product warranty** - The product warranty runs 15 years - standard for the market, but shorter than the 20-25-year product warranties already offered by some premium TOPCon manufacturers - worth weighing when comparing total risk cost over 25-30-year project lifetimes. ## About this series The Phono Solar Draco Module Series (N-TOPCon HIGH EFFICIENCY 144-16BB-W-WG) was designed to maximize yield under real-world operating conditions-especially when irradiance is low or the angle of light incidence is not ideal. The application of **N-TOPCon technology** translates to more stable performance and a better response to low-light conditions, which has direct implications for annual energy production in Poland's climate. The modules utilize a **bifacial structure**, allowing them to capture additional energy from reflected light-particularly beneficial on bright roofs, ground, gravel, or in snowy surroundings. Another key feature is the **16BB configuration**, which supports lower internal losses and more uniform current conduction, while the **double glazing** enhances durability and resilience in demanding locations. This solution is ideal for investors seeking higher yields and reliable performance in commercial installations, utility-scale solar farms, and industrial projects, where long-term reliability is key, not just catalog parameters. ## Notable figures - 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) - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 550-600W\*\* median - Bifaciality factor of 80% can add 4-12% extra yield with reflective mounting surface - In the top 13% for efficiency among all TOPCon panels ## Questions ### What warranty does the Phono Solar Draco N-TOPCon 144-16BB series come with, and what does it cover? The Draco N-TOPCon 144-16BB series includes a 15-year product warranty covering defects in materials and workmanship, plus a 30-year linear power output warranty. After 30 years, Phono Solar guarantees at least 87.4% of nominal power. First-year degradation is capped at 1%, followed by 0.4% per year, giving installers and owners a predictable generation curve throughout the system's operational lifetime. ### What advantage does N-TOPCon cell technology offer in the Phono Solar Draco modules compared to standard PERC? N-TOPCon cells achieve higher module efficiency - up to 23.03% for the 595 W variant - and deliver better low-light response than conventional PERC. The temperature coefficient of Pmax is just -0.29%/°C, meaning less power loss on hot days. In climates with frequent overcast conditions, the improved weak-illumination performance translates into measurably more kWh per year compared to PERC-based modules of similar nameplate power. ### Can Phono Solar Draco 595 W dual-glass modules be installed on a residential pitched roof? The modules measure 2278×1134×30 mm and, due to their dual-glass construction, weigh approximately 32-34 kg each - noticeably more than backsheet modules. Pitched-roof installation is possible but requires a structural load assessment and an appropriately rated racking system. This series is optimized for utility-scale ground-mount arrays, commercial rooftops, and industrial projects where weight is less of a constraint. For residential use, verifying roof structure load capacity is essential before specifying these modules. ### How does bifacial technology work in the Phono Solar Draco series, and how much extra energy can it generate? Draco bifacial modules have active cells on both the front and rear surfaces, capturing light reflected from the ground or mounting surface. Cell bifaciality exceeds 80%, and Phono Solar claims up to 30% additional power yield under optimal albedo conditions. Practical gains depend heavily on surface reflectivity: light-colored gravel, concrete, white roofing membranes, or snow coverage produce the highest rear-side gains. In typical ground-mount installations, real-world bifacial yield uplift ranges from 5% to 15%. ### Do Phono Solar Draco N-TOPCon panels perform well in cold temperatures and winter conditions? Yes. PV modules operate more efficiently at lower temperatures, and the Draco's favorable temperature coefficient of -0.29%/°C means minimal power loss even during summer heat. In winter, cold but sunny days can push output above STC nameplate power. N-TOPCon technology's superior low-light response also ensures solid generation on overcast winter days, which is particularly relevant for high-latitude markets with limited winter irradiance. ### What types of installations is the Phono Solar Draco 144-16BB best suited for, and can it work in a small residential system? The Draco N-TOPCon 144-16BB series, with up to 595 W per module, is engineered for utility-scale ground-mount farms, large commercial rooftops, and industrial PV projects where high per-module power reduces BoS costs and module count. Residential installation is technically possible but requires an inverter with a compatible MPPT voltage and current range, as well as a roof structure capable of supporting the higher weight of dual-glass modules. For typical 5-10 kW home systems, lighter single-glass alternatives may be more practical. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/gl-en-182-draco-n-144-16bb-575-595w-236512be0d3a.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +50 W, lighter, +2.0 pp | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | -35 W, lighter, +1.8 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +45 W, lighter, +1.8 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -40 W, lighter, +1.6 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +40 W, lighter, +1.6 pp | | [Phono Solar PS535M8GF-24/TH](https://comparepv.com/panel/phono-solar-ps535m8gf-24-th) | 535 W | -60 W, hotter, -2.3 pp | | [Phono Solar PS540M8-24/TH](https://comparepv.com/panel/phono-solar-phono-solar-technology-co-ltd-ps540m8-24-th) | 540 W | -55 W, hotter, -2.1 pp | | [Phono Solar PS545M8-24/TH](https://comparepv.com/panel/phono-solar-phono-solar-technology-co-ltd-ps545m8-24-th) | 545 W | -50 W, hotter, -1.9 pp | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +55 W, lighter, +2.2 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +35 W, cooler, +1.4 pp | --- Source: https://comparepv.com/panel/phono-solar-phono-solar-technology-co-ltd-ps595m8gf-24-tnh Not in this file, on the page: the I-V and temperature curves lifted from the manufacturer's datasheet, a thirty-year output simulator, a bifacial gain calculator and alternatives filtered by how closely they match these dimensions.
