JA Solar 720W N-Type Bifacial Solar Panel

Advanced N-Type Bycium+ Cell Technology

The JA Solar 720W N-Type Bifacial Solar Panel is a high-performance double-glass solar module built with advanced N-Type Bycium+ cell technology, an 18-busbar design, and MBB half-cell configuration. This advanced structure improves power generation, reduces electrical losses, and delivers dependable performance throughout the panel’s service life.

High Power Output and Efficiency

With a rated output of 720W and module efficiency of up to 23.2%, the JA Solar JAM66D46-720/LB is designed for commercial, industrial, and utility-scale solar projects. Its high-density module design generates greater power from the available installation area, helping reduce overall system costs and improve energy yield.

Bifacial Power Generation

The bifacial design enables the panel to produce electricity from sunlight received on both its front and rear surfaces. Under BNPI conditions with 1000W/m² front irradiation and 135W/m² rear irradiation, the module can deliver up to 795W, providing significantly higher energy generation than conventional monofacial panels.

Reliable Performance in High Temperatures

The panel features a low power temperature coefficient of -0.290%/°C, helping it maintain stable electricity production during hot weather. Its operating temperature range of -40°C to +70°C makes it suitable for demanding climatic conditions and large outdoor installations.

Durable Double-Glass Construction

Built with 2.0mm anti-reflective front glass, 2.0mm heat-strengthened rear glass, and an anodized aluminium alloy frame, the JA Solar 720W panel provides excellent mechanical strength and long-term environmental protection. It can withstand static loads of up to 5400 Pa on the front and 2400 Pa on the rear.

Long-Term Reliability and Warranty

The module is backed by a 12-year product warranty and a 30-year linear power output warranty. It has only 1% degradation during the first year, followed by approximately 0.4% annual degradation, retaining at least 87.4% of its original output after 30 years.
