Key Features

All-Black Monocrystalline Design

The JA Solar 405W panel features a modern all-black design created using monocrystalline silicon cells. These sleek black modules absorb sunlight more efficiently than traditional blue panels – even at dawn, dusk and on cloudy days.

Their aesthetically pleasing design also allows these panels to blend seamlessly into their environment, making them suitable for all domestic and commercial solar PV installations.

High-Efficiency MBB Half-Cell Configuration

JA 405w solar panels utilise a state-of-the-art MBB half-cell configuration. Instead of 3 or 5 busbars, the solar cells have 12 thin busbars across them, allowing the current to flow more freely. Additionally, the half-cell design offers reduced resistive power loss and better shade tolerance, resulting in a higher energy yield per square metre.  

Together, these innovations mean more sunlight is converted into usable electricity, resulting in increased energy bill savings for your home or business.

Improved Mechanical and Temperature Resistance

Thanks to its MBB half-cut cell design and durable frame, the 405w JA Solar module boasts enhanced tolerance of mechanical loading and improved performance in extreme temperatures.

The advanced glass surface finish is also self-cleaning, offering excellent resistance to dust, sand, salt, snow and other debris. You can count on these robust, reliable solar panels to withstand the elements year-round.

25-Year Linear Power Output Warranty

Featuring advanced PERC cell technology, this solar panel delivers a high 405 watt output with less efficiency lost over time.

JA Solar offers a 12-year product warranty and an extended 25-year power output warranty, guaranteeing an annual degradation rate of only 0.55% after the first year. This means that after 25 years, the module will still produce over 84% of its original rated power.
