Calculate what solar power system you’ll need

Solar power systems are measured in terms of their kilowatt (kW) capacity and kilowatt-hours (kWh) of output. The type of solar power system you’ll need will depend on:

  • the size of your house
  • how many people live in your house
  • how many electrical devices you use
  • the current cost of your quarterly energy bill.

Use the table below to calculate which solar power system you’ll need.
