The JAM66D45-620/LB combines advanced N-Type monocrystalline solar cell technology, bifacial energy generation and durable double-glass construction to provide an efficient photovoltaic solution for a wide range of solar energy installations.
With a rated maximum power of 620W and a module efficiency of 23%, this solar panel is designed to maximize electricity generation from available installation space.
Advanced N-Type Solar Cell Technology
The JA Solar 620W panel incorporates N-Type monocrystalline half-cell technology designed for efficient solar energy conversion and reliable power generation.
Its advanced cell architecture offers improved resistance to light-induced degradation (LID), while its temperature characteristics help support energy production under varying environmental conditions.
The panel also provides a favorable response under lower sunlight conditions, helping support electricity generation during periods of reduced solar irradiance.
Bifacial Technology for Additional Energy Generation
The DeepBlue 4.0 Pro features bifacial solar cell technology, allowing the module to capture sunlight from both its front and rear surfaces.
In suitable installations, sunlight reflected from the ground or surrounding surfaces can reach the rear of the panel and contribute additional energy generation.
Actual bifacial energy gain depends on installation height, mounting configuration, ground reflectivity, shading and local environmental conditions.
This technology makes the panel suitable for appropriately designed ground-mounted arrays, elevated mounting structures and other installations where rear-side sunlight can be utilized.
Durable Double Glass Construction
Engineered for long-term outdoor performance, the JA Solar 620W features a robust double-glass structure with 2.0mm glass on both the front and rear surfaces.
The panel includes a durable aluminum frame and an IP68-rated junction box with three bypass diodes.
This construction is designed to support reliable operation in demanding solar installation environments.
The module is rated for a maximum front-side static load of 5400Pa and a maximum rear-side static load of 2400Pa, subject to approved mounting methods and installation requirements.
High Power Output and Solar System Compatibility
With a rated output of 620W, the JA Solar JAM66D45-620/LB is suitable for appropriately designed residential, commercial, industrial and off-grid photovoltaic systems.
The module has an open-circuit voltage of 48.50V, a maximum power voltage of 40.21V and a maximum power current of 15.42A under Standard Test Conditions.
Its maximum system voltage rating of 1500V DC provides design flexibility for compatible photovoltaic installations.
Solar array configuration must be matched to the inverter or charge controller’s voltage, current and power limits.
Long-Term Performance and Manufacturer Warranty
JA Solar specifies a 12-year product warranty and a 30-year linear power output warranty for the DeepBlue 4.0 Pro module series, subject to the applicable manufacturer’s warranty terms and conditions.
The module’s N-Type cell technology and durable construction are designed to support sustained solar energy generation over its operational lifetime.
Applications
The JA Solar 620W bifacial solar panel is suitable for use in appropriately designed off-grid solar power systems, hybrid solar installations, commercial solar projects, industrial solar systems, agricultural installations, ground-mounted photovoltaic arrays and large-scale solar energy projects.
Whether used for battery charging, solar electricity generation or as part of a larger photovoltaic installation, the JA Solar DeepBlue 4.0 Pro provides an advanced solution for efficient solar power generation.
