Product FAQ

How many Suntech Power STP440S-H48-Nkh 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 Suntech Power STP440S-H48-Nkh?

This panel has an efficiency of 22%, 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 Suntech Power STP440S-H48-Nkh?

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

Is Suntech Power STP440S-H48-Nkh 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 Suntech Power STP440S-H48-Nkh come with?

This panel includes a 15-year product warranty from Suntech Power. 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.
