Solar system calculator
Choose the size of each appliance and how many you'll run at the same time. We've added a typical home to start with. Change anything you like.
Find “Units consumed” on your electricity bill. An average of the last 12 months gives the best estimate, as summer bills are higher.
Divide your bill amount by the units consumed. Used only to estimate the value of the units your panels produce.
From estimate to the right system for your property.
