Hello 
Looking at your user profile page it clocks 162 solutions, however if you look at the tally in your user card it’s 150 [1].
Checking out the badge page for Solution Institution it seems you got the badge 18 hours ago, so yesterday’s solution tipped you over the threshold 
There are some caveats to what counts as an eligible solution for the badge (no self-solves, no solutions on deleted topics, etc), so that may be where the discrepancy between the profile page number and the other tallies is coming from. It seems likely that the calculation for the profile page number needs an update for consistency.
and if you look at the ‘all time’ user directory it’s 149, but the daily job to update the directory hasn’t run yet today
