Just before the interval, Solanke finished off Groeneveld s assist in the 47th minute to put the hosts ahead.
Bournemouth, however, failed to preserve their lead after the restart as goals from Dominik Freiser and Carlton Morris in the 60th and 80th minutes respectively turned the game around for Barnsley.
Solanke played for the entire duration while Kenya s Clark Odour, Nigeria s Victor Adeboyejo and Zimbabwe s Jordan Zemura watched on as unused substitutes from the bench.
Saturday s defeat saw the Cherries drop to seventh in the Championship table after gathering 56 points from 36 matches while Barnsley remain sixth in the play-off zone with a five-point gap.
