Product FAQ

How many LONGi Solar LR4-60HPB-355M panels do I need for my home?

The number of panels depends on your energy consumption and roof area. At 355W per panel, a typical 10kW residential system requires about 29 modules. Use our Solar Roof Calculator to get a precise layout based on your actual roof dimensions.

What is the efficiency of LONGi Solar LR4-60HPB-355M?

This panel has an efficiency of 19.55%, 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 LONGi Solar LR4-60HPB-355M?

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 LONGi Solar LR4-60HPB-355M?

The module dimensions are 1755mm × 1038mm × 35mm. Always account for these measurements plus fire setbacks and mounting clearances when planning your solar layout.

Is LONGi Solar LR4-60HPB-355M 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.

What warranty does the LONGi Solar LR4-60HPB-355M come with?

This panel includes a 12-year product warranty from LONGi Solar. Solar panels typically degrade about 0.4–0.5% per year, meaning this module should retain over 87% of its original output after 30 years.
