Product FAQ

How many LONGi Solar LR4-72HPH-445M panels do I need for my home?

The number of panels depends on your energy consumption and roof area. At 445W 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 LONGi Solar LR4-72HPH-445M?

This panel has an efficiency of 20.5%, using PERC cell technology. Higher efficiency means more electricity per square meter, which is especially valuable when roof space is limited.

What are the dimensions of the LONGi Solar LR4-72HPH-445M?

The module dimensions are 2094mm × 1038mm × 35mm. Always account for these measurements plus fire setbacks and mounting clearances when planning your solar layout.

Is LONGi Solar LR4-72HPH-445M 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.
