Imagine all the electricity going off in your school because there wasn't enough money to pay for it.
That's what's happening to kids at Sithobelumthetho Primary School in South Africa.
So some of the Zulu children have decided to use their singing talent to raise money for solar panels on their school roof.
They're doing a three-week concert tour with their choir in the UK this summer.
Ricky's been to meet the singers.
