The JA Solar JAM54D41-440/LB 440W DeepBlue 4.0 Pro is a high-efficiency N-type bifacial double-glass solar panel designed for residential, commercial, agricultural, and renewable energy installations.

Built with JA Solar's advanced N-type Bycium+ cell technology and 16-busbar MBB half-cell architecture, this module delivers 440W of rated power with 22.0% module efficiency. Its bifacial design captures solar energy from both the front and rear sides of the module, helping increase total energy generation when installed in suitable conditions.

The durable double-glass construction, black module design, excellent low-light response, low temperature coefficient, and strong mechanical load ratings make the JAM54D41-440/LB a dependable option for long-term solar installations in demanding environments.

KEY FEATURES:

• 440W High Power Output – Provides 440W of rated maximum power with 22.0% module efficiency for strong energy production from a compact module footprint.

• N-Type Bycium+ Cell Technology – Advanced N-type cells with 16-busbar MBB half-cell technology help improve efficiency, reliability, and long-term energy production.

• Bifacial Energy Generation – Generates power from both the front and rear sides of the panel, allowing additional production from reflected solar irradiance.

• Double-Glass Construction – Features 1.6mm front glass and 1.6mm rear glass for enhanced durability and long-term protection.

• Excellent Low-Light Performance – Designed to maintain strong energy generation under lower irradiance conditions such as mornings, evenings, and cloudy weather.

• Low Temperature Coefficient – A -0.290%/°C Pmax temperature coefficient helps maintain stronger output as operating temperatures increase.

• Strong Wind & Snow Load Resistance – Rated for static loads up to 5400Pa on the front and 2400Pa on the rear.

• 0 to +3% Positive Power Tolerance – Helps ensure delivered module output meets or exceeds its rated nameplate power.

• 1500V DC System Compatible – Supports modern high-voltage photovoltaic system designs up to 1500V DC.

• 30-Year Linear Power Output Warranty – Designed for long-term performance with no more than 1% first-year degradation followed by a maximum 0.4% annual degradation.
