She scores her first airplay No. 1 since 2014.
The song leads in its sixth week on the list, also marking Lorde's fastest rise to No. 1 on any airplay chart.
"Solar Power" is Lorde's third No. 1 on Adult Alternative Airplay. She led with her first two entries, "Royals," for eight weeks in August-October 2013, and "Team," for four frames in February-March 2014. Since then, she'd sent five entries onto Adult Alternative Airplay, led by the No. 4-peaking "Green Light" in 2017 before her latest triumph.
