The dual-glass design also improves sealing and PID resistance compared to standard glass-backsheet modules. - **Long-standing BNEF Tier 1 listing** - Phono Solar (founded in 2004) has been consistently listed on the Bloomberg NEF Tier 1 list for several years thanks to proven bankability strength, easing financing for commercial and utility-scale projects using this series. - **30/15-year warranty above market standard** - The manufacturer offers a 30-year linear power warranty and a 15-year product warranty, while most TOPCon modules in this segment (including some peer comparables) still offer the standard 25 years of power and 12 years of product coverage. - **High power up to 710 Wp, on par with HJT leaders** - Modules reach up to 710 Wp at up to 22.86% efficiency, matching the competing Heliene 132HC HJT series (710 Wp/22.86%) despite TOPCon's lower manufacturing cost relative to HJT. ## Cons - **Efficiency slightly below segment leaders** - Maximum efficiency of 22.86% is marginally lower than competing series Suntech Ultra X Pro Plus and Talesun TM8G66M (both 22.9% at the same 710 Wp power), a small but measurable gap on datasheet comparison. - **Heavier and thicker dual-glass construction** - The dual-glass build typical of bifacial modules in this class increases module weight compared to standard glass-backsheet panels, which may require reinforced mounting structures on roofs with limited load capacity. ## About this series The Draco Module Series (N-TOPCON HIGH EFFICIENCY 132-18BB-W-WG) is engineered for maximum energy gain where standard modules lose out - under lower irradiance, high temperatures, and challenging installation locations. The use of **N-TOPCon** cells enhances performance in suboptimal conditions and minimizes typical efficiency drops seen in older technologies over time, resulting in more predictable energy production throughout the system's lifespan. Its competitive edge lies in the **bifacial construction**, enabling the module to utilize reflected light from the ground surface - a tangible benefit for ground-mounted installations, flat roofs, vertical configurations, or environments with high reflectivity (e.g., snow). Furthermore, the **double glass** increases mechanical and environmental resilience while supporting long-term parameter stability. The additional interconnection density in the **18BB** wiring scheme promotes stable operation under partial shading and minimizes current path losses. This is an excellent choice for utility-scale PV farms, commercial projects, and challenging installations - where long-term reliability and high yield matter just as much as catalog specifications. ## Notable figures - Efficiency of 22.2% matches the \*\*TOPCon 650-700W\*\* median - At 222.1 W/m² power density, roof space requirements are typical for \*\*TOPCon 650-700W\*\* panels - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 650-700W\*\* median - At 37.7 kg (3.1 kg above \*\*TOPCon 650-700W\*\* median of 34.6 kg), requires checking roof load capacity - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What warranty does the Phono Solar Draco 132-18BB-W-WG panel come with? The Draco series (132-18BB-W-WG) comes with a 15-year product warranty and a 30-year linear power output warranty. Phono Solar guarantees first-year degradation below 1% and no more than 0.4% annual degradation thereafter. After 30 years, the module is warranted to retain at least 80% of its rated power. This ranks among the longer warranty standards available in the high-efficiency module segment on the European market. ### What does 18BB mean on the Phono Solar Draco modules, and does it help with partial shading? 18BB refers to 18 busbars per cell. More busbars shorten the current path within each cell, reducing resistive losses and improving performance under partial shading. In practice, the module maintains more stable output when part of its surface is shaded by chimneys, antennas, or adjacent panel rows. This is particularly valuable in rooftop installations where eliminating shading entirely is difficult or impossible. ### Does the bifacial design of the Phono Solar Draco module actually increase energy yield, and when does it make sense? Yes, but the real benefit depends on the installation environment. Phono Solar rates up to 30% additional yield from the rear side under favorable ground albedo conditions. Best results come from ground-mounted systems with light or white surfaces, flat roofs with white membranes, vertical agri-PV setups, or snow-covered terrain. On a dark sloped roof the rear-side gain is negligible and should not be the primary purchasing argument. ### Are the Phono Solar Draco 710 Wp panels designed for utility-scale solar farms or residential rooftop installations? The Draco 132-18BB series, rated up to 710 Wp, is primarily designed for utility-scale and commercial PV projects. The large format (approx. 2384×1303 mm) and high unit power reduce module count and installation labor, lowering the overall system LCOE. Phono Solar holds Tier 1 status on the BloombergNEF list, which simplifies project bankability for lenders and insurers. ### How do the Phono Solar Draco N-TOPCon modules perform in high summer temperatures? N-TOPCon technology delivers a more favorable temperature coefficient than legacy PERC cells. The Draco 132-18BB modules feature a Pmax temperature coefficient of approximately -0.30%/°C or lower, meaning smaller power losses on hot days compared to typical PERC panels at around -0.35%/°C. For installations in warmer climates this translates into measurably higher energy yield during summer months, when temperatures regularly push module operating conditions well above STC. ### Is Phono Solar a reputable manufacturer capable of honoring a 30-year power warranty? Phono Solar is a Chinese manufacturer classified as Tier 1 by BloombergNEF, confirming financial stability and the capacity to honor long-term warranty commitments. The company has an established presence in European commercial markets, supplying modules to projects that require full bankability. The 15-year product warranty and 30-year linear power warranty are consistent with the standards offered by leading high-efficiency module manufacturers globally. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/gl-en-210-draco-n-132-18bb-690-710w-2e22889c5fd5.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | -40 W, lighter, +3.0 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | Cooler, lighter, +3.0 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | Cooler, lighter, +2.8 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | -45 W, lighter, +2.8 pp | | [AIKO AIKO-A700-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a700-mae78dw) | 700 W | Cooler, lighter, +2.8 pp | | [AIKO AIKO-A695-MAE78Dw](https://comparepv.com/panel/aiko-aiko-a695-mae78dw) | 695 W | Cooler, lighter, +2.7 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | Cooler, lighter, +2.6 pp | | [Phono Solar NS-650MH-132](https://comparepv.com/panel/phono-solar-ns-650mh-132) | 650 W | -40 W, heavier, -1.3 pp | | [Phono Solar NS-655MH-132](https://comparepv.com/panel/phono-solar-ns-655mh-132) | 655 W | -35 W, heavier, -1.1 pp | | [Phono Solar NS-660MH-132](https://comparepv.com/panel/phono-solar-ns-660mh-132) | 660 W | -30 W, heavier, -1.0 pp | | [Phono Solar NS-665MH-132](https://comparepv.com/panel/phono-solar-ns-665mh-132) | 665 W | -25 W, heavier, -0.8 pp | | [Phono Solar NS-670MH-132](https://comparepv.com/panel/phono-solar-ns-670mh-132) | 670 W | -20 W, heavier, -0.7 pp | | [Phono Solar PS695M13GFH-22/WNH](https://comparepv.com/panel/phono-solar-technology-co-ltd-ps695m13gfh-22-wnh) | 695 W | Very close match | | [Phono Solar PS700M13GFH-22/WNH](https://comparepv.com/panel/phono-solar-technology-co-ltd-ps700m13gfh-22-wnh) | 700 W | +10 W, +0.3 pp | | [AIKO AIKO-A805-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a805-grh78dw) | 805 W | +115 W, cooler, +2.9 pp | | [AIKO AIKO-A800-GRH78Dw](https://comparepv.com/panel/aiko-aiko-a800-grh78dw) | 800 W | +110 W, cooler, +2.7 pp | --- Source: https://comparepv.com/panel/phono-solar-technology-co-ltd-ps690m13gfh-22-wnh 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.
