GCL System Integration • gcl m1072gdf 540-560w
Based on a standard 10kW residential installation
Don’t guess your solar potential. Our Roof Layout Designer uses the exact dimensions of the GCL System Integration 545 (545W 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 GCL System Integration 545 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 545W per panel, a typical 10kW residential system requires about 19 modules. Use our Solar Roof Calculator to get a precise layout based on your actual roof dimensions.
This panel has an efficiency of 21.1%, using PERC cell technology. Higher efficiency means more electricity per square meter, which is especially valuable when roof space is limited.
The module dimensions are 2278mm × 1134mm × 30mm. 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.
