Don’t guess your solar potential. Our Roof Layout Designer uses the exact dimensions of the Trina Solar 490W (490W modules) to map out your system. Visually plan your array to see exactly how many modules your roof can support based on its specific footprint.
The Trina Solar 490W is designed for specific solar energy applications. This panel is an excellent choice if you:
Take our Solar Quiz to get a personalized recommendation for panels, inverter, battery capacity, and system size — before you spend money on the wrong setup.
The number of panels depends on your energy consumption and roof area. At 490W per panel, a typical 10kW residential system requires about 21 modules. Use our Solar Roof Calculator to get a precise layout based on your actual roof dimensions.
This panel has an efficiency of 20.3%, using Bifacial, TOPCon, N-type cell technology. Higher efficiency means more electricity per square meter, which is especially valuable when roof space is limited.
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.
The module dimensions are 2187mm × 1102mm × 35mm. Always account for these measurements plus fire setbacks and mounting clearances when planning your solar layout.
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.
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.
