EcoFlow has a reputation for power solar generators with fast recharging capabilities. When they launched the Delta Pro system, it was the largest solar generator they’ve ever created. The Delta Pro co.
[pdf] To charge a 600Ah battery, you need about 1,200W to 1,500W of solar panels. This calculation uses the rule of doubling the solar wattage based on the battery’s capacity. This ensures efficient charging meets your energy needs within a day, maximizing charging efficiency.
[pdf] We just divide 1kW or 1000W by 17.25 watts per square foot to get the roof size in square feet like this: 1kW Solar Panel Area = 1000W / 17.25W Per Sq Ft = 57.97 Square Feet As we can see, we need almost 60 square feet of roof area for a 1kW system (57.97 sq ft, to be specific).
