Formation of oblique solitons by a flow of polariton condensate past an obstacle is considered. The flow is non-uniform due to a finite life-time of polaritons what changes drastically the conditions of formation of oblique solitons compared with the atomic condensate case. The theory shows that the polariton solitons can be generated by a subsonic flow in agreement with the recent experiment [A. Amo {\it et al.}, Science, {\bf 332,} 1167 (2011)]. Geometric form of oblique solitons and other their parameters are calculated analytically and analytical results are confirmed by numerical simulations.
