The key advantage is **excellent performance under low-light conditions** - panels start generating earlier and maintain production for longer throughout the day, helping improve self-consumption and yield stability in Poland, especially during autumn and winter. The applied cell architecture supports **lower long-term degradation**, ensuring the installation remains economically viable for longer and making its return on investment easier to plan. Bifacial variants allow for utilizing reflected light from the ground, translating to **additional yield from the rear side** without complicating the design. This is a series for investors seeking premium quality in residential homes, commercial rooftops, and ground-mounted installations, where maximizing yield from available space and predictable performance over a long horizon matters. ## Notable figures - Efficiency of 22.4% matches the \*\*TOPCon 600-650W\*\* median - At 224.4 W/m², this panel generates 3.3 W/m² less per unit area than \*\*TOPCon 600-650W\*\* median (227.7 W/m²) - Temperature coefficient of -0.29%/°C matches the \*\*TOPCon 600-650W\*\* median - Weight of 34.6 kg is 1.8 kg above \*\*TOPCon 600-650W\*\* median (32.8 kg) - verify structural support - 80% bifaciality enables rear-side power generation, boosting yield by 4-12% on reflective surfaces ## Questions ### What is the power output of Yingli PANDA 3.0 Plus 1 solar panels? The PANDA 3.0 Plus 1 series reaches a maximum power output of up to 735 Wp. This high performance results from N-type TOPCon cells, which make better use of the panel surface and generate more energy from the same installation footprint compared to older PERC technology. ### How do the N-type TOPCon cells in the PANDA 3.0 Plus 1 series differ from standard PERC panels? TOPCon cells include an additional passivation layer that reduces electrical losses and improves performance under weak or diffuse light. In practice, this means an earlier production start in the morning, longer output after sunset, and higher yield in autumn and winter compared to conventional PERC modules. ### Are the bifacial variants of the PANDA 3.0 Plus 1 series worth it for a residential rooftop? Bifacial panels generate extra energy from light reflected off the ground, but the effect is greatest on bright, open surfaces such as ground-mount installations or light-colored rooftops. On a typical sloped residential roof, the gain is usually modest, so bifacial variants are best suited to ground-mount or east-west installations. ### What warranty comes with Yingli PANDA 3.0 Plus 1 panels? The manufacturer provides a 12-year product warranty and a 30-year power performance warranty. This means the panel is covered not only against material and manufacturing defects but also against a guaranteed power output level over a very long horizon, making it easier to plan the investment's payback period. ### Is Yingli a Tier 1 manufacturer, and where are PANDA 3.0 Plus 1 panels made? Yingli is a Chinese manufacturer classified as Tier 1, reflecting long-term financial and production stability confirmed by independent industry rankings. This classification lowers investor risk by increasing the likelihood the manufacturer will remain in business throughout the full warranty period. ### What type of installations is the PANDA 3.0 Plus 1 series best suited for? The series works well on residential rooftops, commercial roofs, and large ground-mount installations. The high per-module output of up to 735 Wp allows more energy to be generated from fewer panels, which is especially valuable when roof space is limited or when maximizing yield from available land is a priority. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/1753060542151-a690b6e8c68a.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | Cooler, lighter, +2.8 pp | | [AIKO AIKO-A680-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a680-mde72mw) | 680 W | +45 W, lighter, +2.8 pp | | [AIKO AIKO-A675-MDE72Mw](https://comparepv.com/panel/aiko-aiko-a675-mde72mw) | 675 W | +40 W, lighter, +2.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | Cooler, lighter, +2.6 pp | | [WINAICO WST-675BKX72-A2](https://comparepv.com/panel/winaico-wst-675bkx72-a2) | 675 W | +40 W, cooler, +2.6 pp | | [AIKO AIKO-G670-MCH72Mw](https://comparepv.com/panel/aiko-aiko-g670-mch72mw) | 670 W | +35 W, lighter, +2.4 pp | | [Longi Solar LR7-72HVHF-670M](https://comparepv.com/panel/longi-lr7-72hvhf-670m) | 670 W | +35 W, lighter, +2.4 pp | | [Yingli YL580DF60f/2](https://comparepv.com/panel/yingli-yl580df60f-2) | 580 W | -55 W, hotter, -1.9 pp | | [Yingli YL585DF60f/2](https://comparepv.com/panel/yingli-yl585df60f-2) | 585 W | -50 W, hotter, -1.7 pp | | [Yingli YL590DF60f/2](https://comparepv.com/panel/yingli-yl590df60f-2) | 590 W | -45 W, hotter, -1.6 pp | | [Yingli YL595D-41f 1/2 / YL595D-41f 1500V 1/2](https://comparepv.com/panel/yingli-yl595d-41f-1-2-yl595d-41f-1500v-1-2) | 595 W | Hotter, -1.4 pp, -5 yr warranty | | [Yingli YL600DF60f/2](https://comparepv.com/panel/yingli-yl600df60f-2) | 600 W | -35 W, hotter, -1.2 pp | | [Gamko New Energy GKA210N120](https://comparepv.com/panel/gamko-new-energy-gka210n120) | 680 W | Hotter, lighter, +1.6 pp | | [Gamko New Energy GKA210N120-675](https://comparepv.com/panel/gamko-new-energy-gka210n120-675) | 675 W | Hotter, lighter, +1.5 pp | | [Q-SUN Solar QN-670HJT-01](https://comparepv.com/panel/q-sun-solar-qn-670hjt-01) | 670 W | +35 W, cooler, +1.3 pp | | [Gamko New Energy GKA210N120-670](https://comparepv.com/panel/gamko-new-energy-gka210n120-670) | 670 W | Hotter, lighter, +1.3 pp | --- Source: https://comparepv.com/panel/yingli-yl635cf60-f-2 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.
