​ Aiko vs JA Solar: Which All-Black Solar Panel is Right for You?

When investing in solar panels, two key considerations are performance and aesthetics. If you’re looking for sleek, all-black panels that blend seamlessly into your roof, Aiko and JA Solar are two leading options. But which one is the best fit for your home or business?

At GreenGenUK, we supply both Aiko and JA Solar panels, and while they share some similarities, they also have distinct differences. This guide will help you decide which panel suits your needs best by comparing key factors such as efficiency, durability, warranty, and overall value.

Overview: What Do Aiko and JA Solar panels Offer?

Both Aiko and JA Solar are respected names in the solar industry, producing high-efficiency panels suitable for homes and businesses alike. They both offer premium all-black solar panels, providing a modern and uniform aesthetic that enhances your property’s appearance.

Power Output & Efficiency

• Aiko: 440W to 460W range (455W model considered here)
• JA Solar: 430W to 455W range (455W model considered here)
• Efficiency: Both brands offer an impressive 22.3% efficiency, meaning they convert a similar percentage of sunlight into electricity. If space is limited, this high efficiency ensures you get the most power per square metre.Please note, these are the current options available, but wattages may change over time as manufacturers release new models.

Warranty & Longevity

• Aiko: 25-year product warranty
• JA Solar: 12-year product warranty
• Both: 30-year performance warranty, ensuring reliable output over time

Aiko’s longer product warranty provides extra peace of mind, protecting your investment for a full 25 years. However, JA Solar’s 12-year product warranty is still a strong offering, particularly for those who want a more budget-friendly option.

Salt Spray Warranty

For properties within 200 meters of the coast, Aiko offers a salt spray warranty to protect against corrosion caused by salt-laden air. If your property is within this range, Aiko will provide an official waiver to ensure the warranty remains valid, so you can have peace of mind knowing your panels are built to withstand coastal conditions.

As we are based in the Southwest, in Cornwall and Devon, we understand the challenges of coastal environments and are here to guide you through the process, ensuring your panels are fully protected.

Durability & Build Quality

• Aiko: 3.2mm tempered front glass for added durability
• JA Solar: 1.6mm front and back glass, offering a lighter-weight design

Aiko’s thicker glass provides greater resistance to impacts from hail, storms, and other harsh weather conditions. JA Solar’s dual-glass design is still robust but offers a slightly lighter panel, which may be beneficial for some roof structures.

Temperature Performance

• Aiko: -0.26%/°C power loss in high temperatures
• JA Solar: -0.30%/°C power loss in high temperatures

Both panels handle heat well, but Aiko’s slightly better temperature coefficient means it will lose less efficiency on very hot days. While the difference is minor, it may be a consideration for those in particularly warm climates.

Technology: N-Type vs. P-Type

• Aiko: Uses advanced N-Type ABC cell technology, which improves efficiency and longevity
• JA Solar: Uses Mono PERC 16-busbar cells, known for solid performance, especially in low-light conditions

Aiko’s N-Type cells are designed to resist light-induced degradation (LID) better, meaning they maintain their efficiency slightly better over time. However, JA Solar’s Mono PERC cells are a well-established, reliable technology.

Aesthetic Differences

Both panels offer an all-black design, but there is a key visual distinction:

• Aiko: No visible metal wires or grid lines, creating a seamless, ultra-modern black appearance
• JA Solar: Matte black design with visible grid lines, offering a more traditional solar panel look

If aesthetics are a top priority and you want the sleekest, most premium-looking panel, Aiko’s seamless design stands out. However, JA Solar still provides a smart, modern look that integrates well with most roof types.
