Its possible that cleaning the condenser coils on the roof may help. If you don't have good air flow on those coils your compressor has to work harder. Higher temperatures means higher head pressure . Higher head pressure means more load on the compressor fighting higher head pressure which in turn draws more amperage. Remove the top cover and wash coils with a hose. Be sure fan has good air flow also. The fins on the coils may need straightening. As it cools down in the evening a little bit the compressor does not have to work as hard .So no more breaker tripping
