Product FAQ
How many Trina Solar TSM-390 DE09.08 panels do I need for my home?
The number of panels depends on your energy consumption and roof area. At 390W per panel, a typical 10kW residential system requires about 26 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-390 DE09.08?
This panel has an efficiency of 20.3%, using Bifacial, TOPCon 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 Trina Solar TSM-390 DE09.08?
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 Trina Solar TSM-390 DE09.08?
The module dimensions are 1754mm × 1096mm × 30mm. Always account for these measurements plus fire setbacks and mounting clearances when planning your solar layout.
Is Trina Solar TSM-390 DE09.08 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-390 DE09.08 come with?
This panel includes a 15-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.
