Product FAQ

How many JA Solar JAM54S40-440/LR panels do I need for my home?

The number of panels depends on your energy consumption and roof area. At 440W per panel, a typical 10kW residential system requires about 23 modules. Use our Solar Roof Calculator to get a precise layout based on your actual roof dimensions.

What is the efficiency of JA Solar JAM54S40-440/LR?

This panel has an efficiency of 22%, using Bifacial, TOPCon, N-type cell technology. Higher efficiency means more electricity per square meter, which is especially valuable when roof space is limited.

Can I get more power from the bifacial JA Solar JAM54S40-440/LR?

Yes. Since this is a Bifacial module, it can capture sunlight from both sides. Depending on the reflectivity (albedo) of your roof surface, you can see a gain of 5% to 25% in total energy yield.

What are the dimensions of the JA Solar JAM54S40-440/LR?

The module dimensions are 1762mm × 1134mm × 30mm. Always account for these measurements plus fire setbacks and mounting clearances when planning your solar layout.

Is JA Solar JAM54S40-440/LR compatible with standard inverters?

Yes, these panels work with most string and hybrid inverters. However, you must check the Voc (Open Circuit Voltage) and Imp (Current at Max Power) against your inverter's MPPT specs.
