Key Features:

• High Power Output: Delivers up to 405W of power with an impressive efficiency of 20.7%, ensuring optimal energy generation for your needs.

• Half-Cell Technology: Utilizes 108 half-cut monocrystalline PERC cells to reduce power loss, improve performance in low-light conditions, and increase overall durability.

• Enhanced Durability: Built to withstand harsh environmental conditions, with front side load capacity up to 3,600 Pa and rear side load capacity up to 1,600 Pa.

• Sleek All-Black Design: Features a black backsheet and black frame for a modern, streamlined look that complements any roof.

• Reliable Warranty: Backed by a 12-year product warranty and a 25-year linear power output warranty, ensuring long-term performance and peace of mind.

The JA Solar 405W panel incorporates Passivated Emitter Rear Contact (PERC) technology, which adds a reflective layer to absorb more sunlight, thereby enhancing power output. The half-cell configuration divides each cell into two, reducing electrical resistance and minimizing the risk of hot spots, leading to improved performance and longevity.

This panel's low temperature coefficient of -0.35% per °C means it maintains high efficiency even in elevated temperatures, making it suitable for various climates. Its robust construction, featuring a 30mm anodized aluminum frame and protective tempered glass, ensures resilience against wind, snow, and hail.

The all-black design not only enhances curb appeal but also benefits from JA Solar's stringent cell color selection and treatment processes, ensuring a uniform and aesthetically pleasing installation. Thinner wires connecting the cells create a smooth, seamless surface, adding to its sleek appearance.

With a maximum system voltage of 1,000V and compatibility with MC4 or MC4-EVO2 connectors, installation is straightforward and adaptable to various system configurations. The panel's dimensions (1722 x 1134 x 30mm) and weight (47.4 lbs) make it manageable for installers while providing substantial power output.

Investing in the JA Solar 405W Black-on-Black 108 Half-Cell Mono DeepBlue 3.0 Light Solar Panel means choosing a product that delivers high efficiency, durability, and a modern aesthetic, all backed by reliable warranties from a trusted manufacturer.
