Product Description

The Jetion Solar JT620SLt(B) is developed for high-performance solar installations that require strong energy output, reliable operation and long service life. With a rated power of 620W and a module efficiency of 23.0%, this panel offers excellent power density and helps reduce the number of modules needed for larger PV systems.

The module uses advanced N-type TOPCon cell technology, which offers improved energy conversion, better low-degradation performance and enhanced resistance against LID and LETID compared with conventional cell technologies. This makes the JT620SLt(B) a strong choice for projects focused on long-term energy yield and stable performance.

Thanks to its bifacial dual-glass construction, the panel can generate energy from both the front and rear sides. Under suitable installation conditions, reflected light from the rear side can increase total energy production, making the module especially effective for ground-mounted systems, commercial rooftops, carports and other installations with reflective surfaces.

The robust dual-glass design provides additional protection against environmental stress, while the module is certified to withstand heavy mechanical loads, including 5400Pa snow load and 2400Pa wind load. The panel is also tested against hail impact, supporting reliable operation in demanding outdoor conditions.

For professional PV installations, the JT620SLt(B) offers a maximum system voltage of 1500V DC, making it suitable for modern high-voltage solar systems. The IP68 junction box, durable aluminium frame and high-quality solar cables support safe and reliable installation.

With a 12-year product warranty and 30-year linear performance warranty, the Jetion Solar JT620SLt(B) provides a dependable long-term solution for customers who need high output, strong durability and efficient solar energy production.
