Since we have a 5kW system, which equates to 5,000 watts, we take 5000 and divide it by 400 watts for each solar panel. This gives us a total of 12.5 panels, which we would round up to 13 panels. Therefore, to run a 5kW solar panel system you need 13 solar panels with a wattage of 400 watts each. [pdf]
