The implementation of **monocrystalline n-type cells in TOPCon technology** ensures more stable performance across a wide range of conditions and improved resistance to common degradation mechanisms, facilitating sustained high production output for years. In practice, this translates to a reduced risk of underestimating energy yields and a more predictable autarky balance. A key differentiator compared to many market offerings is the **bifacial design**, which harnesses reflected light from the ground - a tangible advantage for flat roofs, light membranes, façades, and ground-mounted installations. This design complements an **advanced passivation and contact structure** optimized for high bifaciality, along with **enhanced reliability in challenging environments**. This is the ideal choice for investors seeking more energy from the same surface area - in homes, businesses, and commercial projects. ## Notable figures - Efficiency of 22.6% matches the \*\*TOPCon 550-600W\*\* median - At 226.5 W/m² power density, roof space requirements are typical for \*\*TOPCon 550-600W\*\* panels - 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 - #3716 for efficiency, #2220 for temperature performance out of 14129 panels ## Questions ### What is the maximum power output of the Yingli PANDA 3.0 Pro 1 panel? The PANDA 3.0 Pro 1 series reaches up to 660 Wp, thanks to n-type monocrystalline TOPCon cells with efficiency exceeding 23%. This means fewer panels are needed to reach a target system size compared to conventional PERC modules, while still delivering strong energy yield per module. ### How does TOPCon technology differ from standard PERC panels? TOPCon is an n-type cell technology with an additional passivation layer that reduces recombination losses and improves performance at higher temperatures and under diffuse light. In practice, PANDA 3.0 Pro 1 panels deliver higher energy yield in early morning, evening, and overcast conditions compared to typical p-type PERC modules, with a lower annual degradation rate. ### What does bifacial design mean for the PANDA 3.0 Pro 1 series, and is it worth it? Bifacial construction allows the panel to generate power from its rear side as well, capturing light reflected off the ground or roof surface such as bright membranes, gravel, or snow. For ground-mount, flat-roof, and facade installations, this can add roughly several to a low double-digit percentage in energy yield, though the actual gain depends on mounting height and the albedo of the surface below the array. ### What warranty comes with Yingli PANDA 3.0 Pro 1 panels? The manufacturer provides a 12-year product warranty and a 30-year linear power warranty, guaranteeing at least 87.4% of rated output at the end of that period. This is standard for modern TOPCon modules and notably longer than older PERC-based series, which matters when estimating system profitability over a 25-30 year lifespan. ### Are PANDA 3.0 Pro 1 panels suitable for commercial installations and solar farms? Yes, the high power output of up to 660 Wp, large module dimensions, and bifacial design make the PANDA 3.0 Pro 1 series a strong fit for commercial, industrial, and ground-mount solar farm projects where maximizing yield per square meter of roof or land matters. Due to its size and weight, the module is best suited to flat roofs and ground mounting rather than smaller residential pitched roofs. ### Is Yingli a tier-1 manufacturer, and can it be trusted for a long-term installation? Yingli is a Chinese manufacturer with a long track record in the industry, classified as a tier-1 supplier, which indicates solid financial standing and reliable warranty backing. For investors, this reduces the risk of warranty claim issues over the product's multi-decade product and power warranty period. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/1763542524548-1-e97ec2bda9d9.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [Longi Solar LR7-60HVH-560M](https://comparepv.com/panel/longi-lr7-60hvh-560m) | 560 W | Cooler, lighter, +2.2 pp | | [Longi Solar LR7-60HVH-555M](https://comparepv.com/panel/longi-lr7-60hvh-555m) | 555 W | -30 W, lighter, +2.0 pp | | [AIKO AIKO-A635-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a635-mae72mw) | 635 W | +50 W, lighter, +2.0 pp | | [AIKO AIKO-A630-MAH72Dw](https://comparepv.com/panel/aiko-aiko-a630-mah72dw) | 630 W | +45 W, cooler, +1.8 pp | | [Longi Solar LR7-60HVHL-550M](https://comparepv.com/panel/longi-lr7-60hvhl-550m) | 550 W | -35 W, 15 kg lighter, +1.8 pp | | [Yingli YL530DF72 e/2](https://comparepv.com/panel/yingli-yl530df72-e-2) | 530 W | -55 W, hotter, -2.1 pp | | [Yingli YL535DF72 e/2](https://comparepv.com/panel/yingli-yl535df72-e-2) | 535 W | -50 W, hotter, -1.9 pp | | [Yingli LF535M10-72H](https://comparepv.com/panel/yingli-lf535m10-72h) | 535 W | -50 W, hotter, -1.9 pp | | [Yingli YL540DF72 e/2](https://comparepv.com/panel/yingli-yl540df72-e-2) | 540 W | -45 W, hotter, -1.7 pp | | [Yingli LF540M10-72H](https://comparepv.com/panel/yingli-lf540m10-72h) | 540 W | Hotter, -1.7 pp, -5 yr warranty | | [AIKO AIKO-A650-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a650-mae72mw) | 650 W | +65 W, lighter, +2.6 pp | | [AIKO AIKO-A645-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a645-mae72mw) | 645 W | +60 W, lighter, +2.4 pp | | [AIKO AIKO-A640-MAE72Mw](https://comparepv.com/panel/aiko-aiko-a640-mae72mw) | 640 W | +55 W, lighter, +2.2 pp | --- Source: https://comparepv.com/panel/yingli-yl585cf72-e-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.
