Yingli 400W Solar Panel 108 Cell All Black YL400D-37e-1/2 Clearance

Among the newest offerings of Yingli, YL400D-37e is part of the YLM-J series. These panels use state-of-the-art technology to achieve high efficiency and dependability. This panel takes full advantage of the Passivated Emitter Rear Contact (PERC) technology that allows it to capture up to 12% more energy. All thanks to a reflective layer on the back. This design maximizes the number of photons absorbed by solar cells.

To further boost the performance, Yingli employs half-cut cell technology. Each of the panel’s 108 cells is only half the size of a traditional solar cell. This grants YL400D-37e lower resistive losses and better shade tolerance. As a result, the panel achieves an impressive efficiency of 20.5%. Novel design solutions allow this panel to look as well as it performs. This model is just 1.18" in depth and is jet black with a sleek finish. The panel's functionality and durability are not affected by its aesthetic appeal though. Yingli paid as much attention to durability as they did to performance. YL400D-37e is guaranteed to retain at least 84.8% of output after 25 years. Product warranty for this panel lasts 12 years.

Increased efficiency of up to 20.5 percent

YL400D-37e ensures maximum power production. The combination of PERC technology and a powerful antireflective coating results in 20.5 percent module efficiency. This is much greater than the average, resulting in significant extra savings over the years of production.

Heat-resistant performance

The heat is less of a problem with this module: with one of the industry's lowest temperature coefficients, YL400D-37e loses just -0.35% of efficiency for every 1.8°F over 77°F.

High quality standards

Yingli stringent production requirements include various tests to guarantee high quality. The facilities are highly automated, allowing the manufacturer to maintain high standards while keeping warranty claims to a minimum.

Reliability and degradation resistance

Yingli guarantees limited degradation over the ensuing 25 years. The performance will only degrade by a maximum of 2% the first year, and then only by a maximum of 0.55% yearly after that. After the 25 years are over, your modules will still show at least 84.8% of nominal capacity. A substantial 12-year product warranty is also included with this 400 W Yingli solar panel.

Certified for the most challenging environmental conditions

YL400D-37e is resistant to PID, salt, acid and ammonia. It can also withstand up to 5400 Pa mechanical load on the front and 2400 Pa on the back. Such robustness is mainly due to the 1.18" thick aluminum alloy frame and a layer of protective glass.

Outstanding all-black design

The panel features all-black design which looks great on any roof. The manufacturer ensures excellent cell color by special treatment and selection processes. Yingli engineers use thinner wires to connect the cells, and at a distance the surface of the modules appears smooth and uninterrupted.
