The physical size of solar panels can vary based on their efficiency and wattage. On average, a standard solar panel measures about 65 inches by 39 inches (approximately 1.65 meters by 1 meter) and covers an area of around 17 square feet (1.58 square meters). Therefore, to install a 4kW solar system, you can expect the total area required to be between 200 to 300 square feet (18.6 to 27.9 square meters), depending on the efficiency of the solar panels chosen.
