The former Castleford Tigers flyer was disciplined along with Leicester Tigers centre Manu Tuilagi because of "team culture issues" earlier this month.
Solomona and Tuilagi allegedly went out of their hotel after hours and alcohol was thought to be involved before they were later sent home for their actions.
Having accepted the decision, Solomona is determined to put things right and impress head coach Eddie Jones with his performances for Sale in the coming months.
Solomona was quoted by the BBC, saying: "He (Jones) has just said to train harder and play harder and that's what I'll do. I need to do what he says. That's the only way I'll achieve what I want to achieve.
"By training hard, I'll improve my game capabilities and I'll learn a lot more. And in the game I'll go as hard as I can and give everything I've got every single game.
"I'm hungry for it. I'm eager for it and I'm only going to train harder and play as good as I can to let my rugby do my talking."
