About product

400MLQPG10-BK is a model that uses a number of technologies to bring durability and performance to the next level. 400MLQPG10-BK employs monocrystalline silicon — the most efficient material for converting sunlight into electricity. Each of the model's 132 solar cells consists of a single crystal, unlike cheaper polycrystalline cells that are made of multiple crystals melted together. As a result, not only are monocrystalline panels more efficient, but they are also more resistant to degradation. To further boost the performance, Q CELLS employs half-cut cell technology. Each of the panel’s 132 cells is only half the size of a traditional solar cell. This grants 400MLQPG10-BK lower resistive losses and better shade tolerance. At 20.4% efficiency, 400MLQPG10-BK offers surprising performance for its weight and size. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. Q CELLS paid as much attention to durability as they did to performance. 400MLQPG10-BK is guaranteed to retain at least 86% of output after 25 years. Product warranty for this panel lasts 25 years.

High efficiency of 20.4%

Q CELLS Q.PEAK DUO BLK panels take full advantage of the company’s technologies that have won Q CELLS multiple awards. This monocrystalline option offers higher power output per square foot of PV modules. This means quicker installation times and fewer clamps and racks. All of which reduces your overall costs, shortening the payback time.

Better performance at high temperatures

Excellent temperature coefficient means more energy as temperature rises. Every 1.8°F hike above 77°F will decrease your panel’s efficiency by only 0.34%.

High quality standards

Q CELLS strict manufacturing standards include 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.

Reliability and degradation resistance

Slow degradation over the next 25 years is guaranteed by Q CELLS. The performance will decrease no more than 2% during the first year and then will be limited to 0.50% annually. Your modules will retain at least 86% of original performance after the 25 years are over. This 400 W Q CELLS solar panel also comes with a generous 25-year product warranty.

Enhanced frame design

400MLQPG10-BK design makes it ideal for residential and commercial rooftops. Strong 1.26" frame made from anodized aluminum increases durability and strength. The model can support 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.

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. Q CELLS engineers use thinner wires to connect the cells together, and at a distance the surface of the modules appears smooth and uninterrupted.

I had been operating a system made of QCells panels for a while. Purchased additional panels to guarantee that early sun is also caught. A1Solar had the best price for this particular model

Panels and optimizers appear to be operating as intended, however due to the panels' current location (it’s summer), they experience shading issues. Due to this, we have not yet reached full output (the building is not perfectly located or orientated, which is obviously not A1Solar’s fault). We'll have to wait and observe how the change of seasons affects the issue.

Yes, they are compatible.
Given the high power, would it be advisable to use it for a residential install?
07/16/2022, 13:54
There is absolutely no reason not to consider it for residential application, just keep in mind the larger dimensions of this model.
Is there a minimum order size for delivery? What about pickup?
06/10/2022, 21:06
At the moment of writing the minimum order size for delivery of this item is 10 panels. There is no minimum if you opt for pickup.
