Product FAQ

How many Trina Solar TSM-DE09R 420W panels do I need for my home?

The number of panels depends on your energy consumption and roof area. At 420W per panel, a typical 10kW residential system requires about 24 modules. Use our Solar Roof Calculator to get a precise layout based on your actual roof dimensions.

What is the efficiency of Trina Solar TSM-DE09R 420W?

This panel has an efficiency of 21%, using 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 Trina Solar TSM-DE09R 420W?

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

Is Trina Solar TSM-DE09R 420W 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 Trina Solar TSM-DE09R 420W come with?

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