Product FAQ

How many Sunman Energy SMF520J-12X12UW panels do I need for my home?

The number of panels depends on your energy consumption and roof area. At 520W per panel, a typical 10kW residential system requires about 20 modules. Use our Solar Roof Calculator to get a precise layout based on your actual roof dimensions.

What is the efficiency of Sunman Energy SMF520J-12X12UW?

This panel has an efficiency of 19.34%, 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 Sunman Energy SMF520J-12X12UW?

The module dimensions are 2246mm × 1197mm × 2mm. Always account for these measurements plus fire setbacks and mounting clearances when planning your solar layout.

Is Sunman Energy SMF520J-12X12UW 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 Sunman Energy SMF520J-12X12UW come with?

This panel includes a 12-year product warranty from Sunman Energy. 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.
