The teenage winger had been unwell for a few months and had not featured in the national league competition this season.
Many of his former teammates and coaches attended his funeral in Honiara on Monday and President of the Solomon Islands Football Federation, William Lai, said it was a sad day.
"I think it's sad because he was such a talented football player and he's so young and we were all saddened about his sudden passing away."
Chris Satu played a key role in the Solomon Islands team that qualified for the 2019 Under 17 World Cup in Brazil.
