The 400MLBK is a solar panel model that offers exceptional durability and performance through the use of advanced technologies. It employs monocrystalline silicon, which is the most efficient material for converting sunlight into electricity. Unlike cheaper polycrystalline cells that are made of multiple crystals melted together, each of the model's 132 solar cells consists of a single crystal, making the panel not only more efficient but also more resistant to degradation.

To further enhance its performance, the 400MLQPG10-BK uses half-cut cell technology, with each of its 132 cells being only half the size of a traditional solar cell. This grants the panel lower resistive losses and better shade tolerance, resulting in a surprising 20.4% efficiency for its weight and size. The cell surface, back foil, and frame are all completely black, giving the panel unrivaled aesthetics.

High quality standards

Q CELLS paid as much attention to durability as they did to performance. The 400MLQPG10-BK is guaranteed to retain at least 86% of its output after 25 years, and the product warranty for this panel lasts 25 years. This panel offers 400 W power output, 132 half-cut monocrystalline cells, 20.4% efficiency, 1000 V DC maximum system voltage, MC4 connectors, and 25-year product and performance warranties.

The Q CELLS Q.PEAK DUO BLK panels, including the 400MLQPG10-BK, take full advantage of the company's technologies, offering higher power output per square foot of PV modules. The excellent temperature coefficient means more energy as temperature rises, with the panel's efficiency decreasing only 0.34% for every 1.8°F hike above 77°F.

Reliability and degradation resistance

Q CELLS has strict manufacturing standards, including multiple tests to provide extreme quality assurance. The facilities are highly automated, allowing the company to maintain high standards and keep the level of warranty claims very low.

The enhanced frame design of the 400MLQPG10-BK makes it ideal for residential and commercial rooftops. Its strong 1.26" frame made from anodized aluminum increases durability and strength, with the model capable of supporting a heavy snow load up to 5400 Pa. The back of the panel can handle 4000 Pa, ensuring that your system will survive the strongest of winds. Overall, the 400MLQPG10-BK is an excellent choice for those seeking high efficiency, durability, and performance from their solar panel system.
