You need 12-13 x 400W solar panels to get 20kwh a day. This assumes you have 5 peak sun hours and each panel produces 390 watts. You can also run these examples with other solar panel sizes to see how many you would need. From this example you can see how the number of peak sun hours affects the results.
Moreover, you can also play around with our Solar Panel Daily kWh Production Calculator as well as check out the Solar Panel kWh Per Day Generation Chart (daily kWh production at 4, 5, and 6 peak sun hours for the smallest 10W solar panel to the big 20 kW solar system).
The number of batteries needed for a 20kW solar panel system depends on the battery type. If you opt for the recommended lithium polymer batteries, you would require a total battery capacity of 126 kWh.
Most solar panels have a capacity of 300 watts. To achieve a 20kW solar system, you will need 67 or more panels. Each panel occupies approximately 17 square feet, resulting in a total footprint of 1133 square feet for a 20kW solar system.
