What is our own estimate

The cost ranges and savings on our cost pages are our own estimates, built on the sources above. They assume a typical south-facing roof making about 900 kWh for each kWp a year, 35% of solar power used in the home, a battery that loses about 10% of power, and a home using 3,000 kWh a year. They are not quotes. Last reviewed 7 October 2026.
