JA Solar • deepblue 4.0 pro jam66d45-605-630lb
Based on a standard 10kW residential installation
Don’t guess your solar potential. Our Roof Layout Designer uses the exact dimensions of the JA Solar JAM66D45-620/LB (620W modules) to map out your system. Visually plan your array to see exactly how many modules your roof can support based on its specific footprint.
The JA Solar JAM66D45-620/LB is designed for specific solar energy applications. This panel is an excellent choice if you:

The number of panels depends on your energy consumption and roof area. At 620W per panel, a typical 10kW residential system requires about 17 modules. Use our Solar Roof Calculator to get a precise layout based on your actual roof dimensions.
This panel has an efficiency of 23%, using Bifacial, N-type cell technology. Higher efficiency means more electricity per square meter, which is especially valuable when roof space is limited.
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.
The module dimensions are 2382mm × 1134mm × 30mm. Always account for these measurements plus fire setbacks and mounting clearances when planning your solar layout.
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.
