The Norway striker has moved to Palace from Wolves for £45m, penning a deal to 2030.
Strand Larsen told the Palace website: “As soon as I heard there was interest, it’s something I wanted to jump on.
“I feel like it's what I need and hopefully what the club needs as well. I'm here to bring energy, goals and to try and do the best for the club.
“There’s obviously many things to look into when you are changing clubs. But I’m looking at what the club wants from me – and what the club is looking to do in the future.
“I’m coming in to hopefully help win some games and bring the team back to where it was at the start of the season, because obviously that was amazing.
“It just shows Palace can definitely be there (in the top half) and should be there. Hopefully that’s what I can do.”
He also said: "It feels safe to come here and it feels like I'm going to get the service I need. That is really important as well for me.
“I'm a tall striker. I like to be in and around the box. I've always had a nose for a goal.”
