The output of a 13.2kw solar system

For a larger home, a 13.2kW household solar power system can be ideal. A 13.2kW solar system will require 31 solar PV panels equal to a standard 425-watt panel. Similarly, 34 solar panels will be needed if using 390-watt panels. A 13.2kW solar system will require between 475 and 615 square feet of roof area for installation. The savings made from a 13.2kW solar system are determined by how much solar energy you can utilise at home at the time of production. With a 13.2kW solar panel, you can save anywhere from $1000 to $1300 per quarter on your utility bill.
