JA Solar 620W Panel | N-Type Bifacial

JA Solar 620W Panel – N-Type Bifacial Solar Module

The JA Solar 620W Panel is a high-power bifacial solar module for residential, commercial and industrial solar systems. With a rated output of 620W, it provides strong power generation while helping reduce the number of panels required for larger installations.

The panel uses N-Type monocrystalline technology together with a bifacial design. Therefore, it can generate power from sunlight reaching the front surface. In addition, the rear side can use reflected sunlight to contribute additional energy under suitable installation conditions.

JA Solar 620W Panel Performance

The JA Solar 620W Panel provides a rated maximum power output of 620W. Furthermore, the JAM66D45-620/LB model offers a module efficiency of approximately 23.0%.

This high efficiency helps installers produce more power from the available installation area. As a result, the panel works well for projects where high power density is important.

The module also uses N-Type cell technology. Therefore, it provides a modern solution for long-term solar energy generation.

N-Type Bifacial Technology

Bifacial technology allows the solar module to generate energy from both sides. The front surface captures direct sunlight as a standard solar panel would.

Meanwhile, the rear surface can use reflected light from the surrounding area. As a result, the panel may produce additional energy when installed under suitable conditions.

However, actual rear-side energy production depends on several factors. These include mounting height, surface reflectivity, panel spacing and installation conditions.

Durable Double-Glass Construction

The JA Solar module uses a double-glass design. This construction helps provide additional protection for the solar cells.

In addition, the module has an aluminium frame and an IP68-rated junction box. Therefore, it is designed for long-term outdoor solar installations.

The panel can operate across a wide temperature range. This makes it suitable for different residential, commercial and industrial environments.
