.The dimensions of a 390W solar panel typically range from about 65 inches by 39 inches (approximately 1.65m x 1m) to 67 inches by 40 inches (about 1.7m x 1.02m), depending on the manufacturer and specific technology used. The thickness of the panel usually varies between 1.5 to 1.8 inches. These dimensions are generally consistent across various manufacturers, but slight variations can occur due to differences in design, materials, and manufacturing processes.
