Director of cricket Chris Adams told
BBC London 94.9:
"Considering what's happened to the side in recent weeks, to suddenly find ourselves in this position where we are recruiting and rebuilding and the first signing is Vikram Solanki, I'm delighted with that.
"He's a terrific player, somebody I've played against a lot in the back end of my career. He is a very, very dangerous batsman in all forms of the game and he comes with a great career behind him and still with years to go.
"I asked a few of my own players this week about Vikram and also players that he would have played against over time and, to a man, all gave a great endorsement."
"Vikram approached the club a few weeks ago with regards his future, as his contract ends this September, and it was expressed at that time that the county would not be in a position to offer a contract but hoped to be in a position to do so later in the year when the club's financial position is clearer," he said.
"The club fully understood Vikram's wish to have greater certainty about his future and gave permission for him to talk to other counties due to his long standing at the club.
"We understand Vikram has now received and accepted an offer from Surrey and therefore reluctantly Vikram will be leaving the club at the end of the season.
"The club and its supporters thank Vikram for his 20 years of service to the county, and for his elegant batting and successful captaincy."
