Middle of its segment, heavy for its output
The Phono Solar Draco series introduces a new quality to prosumer installations, basing its design on advanced N-type TOPCon cell technology. Thanks to this approach, these panels offer significantly higher efficiency and better performance characteristics in full sun and at high temperatures. A key differentiator of the series is bifacial light absorption, which allows for generating additional energy from rays reflected off the ground, making them an ideal choice for ground-mounted installations and flat roofs. These modules effectively solve the problem of power loss over time, offering low potential-induced degradation, which directly translates into a longer lifespan and a faster return on investment. This solution is primarily dedicated to homeowners and companies that want to maximize yields from a limited mounting area. What sets Draco ahead of the competition is its excellent performance in low sunlight conditions and high mechanical resistance to snow and wind loads. By investing in this series, the user gains the certainty of stable energy production throughout the year, regardless of the whims of the weather, while maintaining an aesthetic appearance and the highest fire safety standards. Every element of the construction has been optimized to minimize resistive losses, making the Draco series one of the most substantial choices on the Polish photovoltaic market today.
Ranking
Signals from the data
Residential, commercial, utility-scale and hot-climate.
Weight-limited structures, tight roof space and roofs where every square metre has to count.
Bottom 14% of the TOPCon 550-600 W segment, against a median of 53.8.
Bottom 19% of the TOPCon 550-600 W segment, against a median of 22.44%.
Bottom 20% of the TOPCon 550-600 W segment, against a median of 224.4.
N-type TOPCon cells combined with >80% bifaciality deliver up to 30% additional energy yield from reflected light, which is especially noticeable on light-colored ground cover or flat-roof installations.
The manufacturer guarantees 87.4% of nominal power after 30 years of operation, with linear annual degradation of 0.4% and less than 1% first-year degradation - a clear improvement over the older 25-year/84.8% standard offered by many competitors.
The maximum efficiency of 23.32% at 630 Wp matches the best peer comparables - Jinko Solar Tiger Neo 66HL4M-BDV and Resun Solar RS8H-M-BD - and clearly exceeds Leapton's LP182*199-M-72-NH (22.54%).
Phono Solar (founded in 2004) has been continuously listed on Bloomberg NEF's Tier-1 list since 2014, confirming manufacturer financial stability and easing bank financing for projects.
POE encapsulation and dual-glass construction provide strong resistance to potential-induced degradation (PID), while the low -0.29%/°C temperature coefficient supports more stable output in high-temperature conditions.
The modules are only certified to IEC 61730 Fire Class C, the lowest of the three available fire-resistance categories. In some countries and building types (e.g., pitched roofs near property boundaries), this may require additional fire protection measures.
Launched in 2022, the Draco series tops out at 23.32% efficiency and 630 Wp, while Jinko Solar's successor line, Tiger Neo 3.0, already delivers up to 24.8% efficiency and 670 Wp in 2026 - showing that Draco's technology has been partly overtaken by the newer TOPCon generation.
- Module efficiency of 21.9% is 0.6pp below average for TOPCon 550-600W panels (median: 22.4%)
- 218.7 W/m² power density is 5.7 W/m² below TOPCon 550-600W median (224.4 W/m²) - requires larger installation area
- Temperature coefficient of -0.29%/°C matches the TOPCon 550-600W median
- Bifacial design (80% factor) captures reflected light - adds 4-12% yield on ground-mount or white roof
- #6971 for efficiency, #2220 for temperature performance out of 14129 panels
