JA Solar JAM72D42-630/LB solar pane

High Performance and Modern Technology

The JA Solar JAM72D42-630/LB solar panel is a high-performance module with a rated power output of 630 W, built using n-type TOPCon technology. Its bifacial double-glass design allows it to efficiently utilize not only direct sunlight, but also reflected and diffused solar radiation from the rear side, increasing the overall energy yield of the system. The module efficiency reaches up to 22.5%, while the power tolerance ranges from 0 to +3 W.

Construction and Cells

The module consists of 144 n-type monocrystalline cells made in a half-cell configuration, which reduces energy losses caused by partial shading and improves reliability. The panel measures 2465 × 1134 × 35 mm and weighs about 34.6 kg, making it convenient for installation on building rooftops or ground-mounted solar plants.

Operating Voltage and Mechanical Strength

A high operating voltage of up to 1500 V helps reduce losses in cable lines and optimize the design of large-scale systems. The module withstands significant mechanical loads — up to 5400 Pa on the front side and up to 2400 Pa on the rear side — ensuring stable operation even in challenging climatic conditions.

Durability and Protection

The double-glass (glass/glass) structure improves the durability of the panel, making it resistant to corrosion, ultraviolet radiation, and mechanical impact. This ensures stable operation for decades and a longer service life compared to traditional modules.

Applications

The JAM72D42-630/LB model is ideally suited for large industrial solar power plants, commercial rooftop projects, and systems with limited space where maximum power per unit area is essential. The bifacial effect provides additional generation on highly reflective surfaces such as concrete or light-colored sand.

Connection and Warranties

The panel is equipped with a reliable IP68 junction box with three diodes, supplied with 1500 mm cables and MC4-EVO2 connectors, which simplifies installation and connection. The manufacturer provides a 12-year product warranty and a 30-year linear performance warranty guaranteeing at least 87% of the output power.

Practical Advantages

The JAM72D42-630/LB model combines high efficiency, durability, and bifacial generation. It helps optimize installation, reduce losses, achieve maximum energy output from limited space, and operate reliably even in difficult climatic conditions.
