This series stands out with its 72-cell design, which provides higher surface efficiency compared to standard residential modules. A key advantage is **excellent thermal stability**, allowing for high energy yields even on hot days, which directly translates into a faster return on investment. The manufacturer has focused on **reinforced mechanical resistance**, enabling the modules to easily withstand extreme weather conditions such as strong winds or heavy snow. Yingli LF340P6-72 solves the problem of performance degradation over time by using technology that prevents the PID effect, guaranteeing long-term system reliability. This solution is primarily dedicated to investors building solar farms and large rooftop systems, where **maximizing production per hectare** or warehouse roof is essential. Compared to the competition, this series is characterized by an exceptional balance between price and component durability. The use of **high-quality polycrystalline cells** makes these panels less sensitive to changes in the light spectrum, allowing for efficient operation in conditions of Polish, often diffused sunlight. The robust frame design facilitates installation and ensures the rigidity of the entire structure over decades of operation. ## Notable figures - Module efficiency of 16.8% is 5.1pp below average for \*\*database\*\* panels (median: 21.8%) - At 167.5 W/m², this panel generates 50.6 W/m² less per unit area than \*\*database\*\* median (218.1 W/m²) - -0.41%/°C temperature coefficient - 0.11pp worse than \*\*database\*\* median (-0.30%/°C), expect higher hot weather losses - Weight of 22.0 kg (4.5 kg below \*\*database\*\* median of 26.5 kg) allows easier transport and roof mounting - #13636 for efficiency, #13862 for temperature performance out of 14129 panels ## Questions ### Are Yingli LF340P6-72 panels still available for purchase? The LF340P6-72 series has been discontinued by Yingli and replaced by newer, higher-efficiency modules. Availability is now limited to distributor stock and the secondary market. If you're expanding an existing installation built with these panels, it's worth acting quickly while remaining batches are still in stock. ### What warranty comes with Yingli LF340P6-72 panels? The manufacturer provides a 12-year product warranty covering material and workmanship defects, plus a 25-year power performance warranty, which is standard for tier-1 class panels. After 25 years, the panel should still deliver a substantial share of its original 340 Wp rated output, making it a solid long-term investment. ### How does the 72-cell design of the LF340P6-72 differ from standard 60-cell panels? A 72-cell design means a larger active surface area, allowing the module to deliver higher power output at the same cell efficiency compared to smaller formats. This layout is typical for commercial installations and solar farms, where maximizing energy yield per available roof or ground area matters more than the panel's larger dimensions and weight. ### Does the Yingli LF340P6-72 perform well in Poland's climate with diffuse sunlight? Yes, the high-quality polycrystalline cells used in this series are less sensitive to shifts in the light spectrum than monocrystalline cells, resulting in more stable energy production under the cloudy, diffuse conditions common in Poland. The panel's good thermal stability also helps maintain high yields even during hot days. ### What is anti-PID technology in the LF340P6-72, and does it actually matter? Anti-PID technology prevents potential-induced degradation, the gradual power loss caused by voltage differences between cells and the frame, which is especially common in large series-connected installations. In the LF340P6-72, this protects long-term reliability of solar farms and large rooftop systems, minimizing the risk of unplanned output loss after several years of operation. ### Are Yingli LF340P6-72 panels bifacial, generating power from the rear side? No, the LF340P6-72 series is a monofacial panel using classic polycrystalline cells that generate power only from the front side. If you're looking for extra yield from reflected light, for example on bright ground surfaces or metal roofing, consider newer bifacial series now offered by tier-1 manufacturers. ## Datasheet [Manufacturer datasheet (PDF)](https://comparepv.com/datasheets/2-06ad64c11927.pdf) ## Alternatives | Panel | Power | How it differs | | --- | --- | --- | | [SunLink LNSK-340M](https://comparepv.com/panel/sunlink-lnsk-340m) | 340 W | +15 W, cooler, +3.3 pp | | [Canadian Solar CS3K-330P](https://comparepv.com/panel/canadian-solar-cs3k-330p) | 330 W | Cooler, lighter, +3.1 pp | | [Canadian Solar CS3K-335MB-AG](https://comparepv.com/panel/canadian-solar-cs3k-335mb-ag) | 335 W | Cooler, +3.1 pp, +5 yr warranty | | [SunLink LNSK-335M](https://comparepv.com/panel/sunlink-lnsk-335m) | 335 W | +10 W, cooler, +3.0 pp | | [Canadian Solar CS3L-365P](https://comparepv.com/panel/canadian-solar-cs3l-365p) | 365 W | +40 W, cooler, +2.9 pp | | [Canadian Solar CS3K-325P](https://comparepv.com/panel/canadian-solar-cs3k-325p) | 325 W | Cooler, lighter, +2.9 pp | | [Canadian Solar CS3L-360P](https://comparepv.com/panel/canadian-solar-cs3l-360p) | 360 W | +35 W, cooler, +2.8 pp | | [SunLink LNSK-330M](https://comparepv.com/panel/sunlink-lnsk-330m) | 330 W | Cooler, lighter, +2.7 pp | | [Yingli LF320P6-72](https://comparepv.com/panel/yingli-lf320p6-72) | 320 W | -0.3 pp | | [Yingli LF330P6-72](https://comparepv.com/panel/yingli-lf330p6-72) | 330 W | +0.3 pp | | [Yingli LF335P6-72](https://comparepv.com/panel/yingli-lf335p6-72) | 335 W | +10 W, +0.5 pp | | [Yingli LF340P6-72](https://comparepv.com/panel/yingli-lf340p6-72) | 340 W | +15 W, +0.8 pp | | [Maxeon SPR-MAX7-475](https://comparepv.com/panel/maxeon-spr-max7-475) | 475 W | +150 W, +7.2 pp, +15 yr warranty | | [Maxeon SPR-MAX7-470](https://comparepv.com/panel/maxeon-spr-max7-470) | 470 W | +145 W, +6.9 pp, +15 yr warranty | | [Maxeon SPR-MAX7-465](https://comparepv.com/panel/maxeon-spr-max7-465) | 465 W | +140 W, +6.8 pp, +15 yr warranty | | [Maxeon SPR-MAX6-440](https://comparepv.com/panel/maxeon-spr-max6-440) | 440 W | Cooler, +6.1 pp, +15 yr warranty | --- Source: https://comparepv.com/panel/yingli-lf-325p6-72 Not in this file, on the page: a thirty-year output simulator and alternatives filtered by how closely they match these dimensions.
