Description
xPACK OF 12 JA-Solar 450w Full Black Dual Glass Bifacial Solar Panel
The JA Solar 450W Full Black N-type Bifacial Double Glass Solar Panel brings superior efficiency for both residential and commercial uses. The eye-catching appearance will give your solar installation a modern appeal. Meanwhile, the bifacial design delivers more energy (and provides more value) than traditional single-sided panels.
Generates 3.9% more energy with Bycium N Type Cells Compared to other Bifacial panels.
Where does this value come from? The front panel can produce 450W, while the back generates an additional 90W through reflected light. The design and 1500V system capacity make this panel flexible enough to work in different settings, including utility-scale arrays, off-grid setups, residential rooftops, and hybrid installations.
The impressive 22% efficiency rating ensures maximum energy generation during daylight hours, and the 30-year lifespan means the output won't diminish for a long time after installation. The lifespan isn't affected by harsh conditions, since the panel can handle snow loads of up to 5400 Pa and wind loads of 2400 Pa.
The compact dimensions (1762 mm × 1134 mm × 30 mm) give you flexibility for placement. The Stäubli MC4-EVO2 connectors, 300mm positive, and 400mm negative cables also help streamline installation and save you from buying additional components.
Finally, our 30-year linear power output warranty gives you peace of mind that the panel will continue its exceptional power output for the long term.
