About the guides
Where do the figures in these guides come from?
$6,774 for 6.6 kW and every other price is the Solar Scorecard Price Index reading for October 2026, from installer offers after the STC discount; tariffs, yields and scheme rules come from the data files linked on each page.
How often are the guides updated?
Monthly, on the index reading day, when every price on the site is re-read; the "Prices checked" line on each guide shows the date.
