Product FAQ

How many Talesun Solar 400 panels do I need for my home?

The number of panels depends on your energy consumption and roof area. At 400W per panel, a typical 10kW residential system requires about 25 modules. Use our Solar Roof Calculator to get a precise layout based on your actual roof dimensions.

What is the efficiency of Talesun Solar 400?

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 Talesun Solar 400?

The module dimensions are 1722mm × 1134mm × 30mm. Always account for these measurements plus fire setbacks and mounting clearances when planning your solar layout.

Is Talesun Solar 400 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 Talesun Solar 400 come with?

This panel includes a 12-year product warranty from Talesun 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.
