Two use cases I can think of are if there is no spare capacity left to add another breaker or if the panel is quite a distance from the garage but there's an existing circuit that could be tapped.
In the case of adding solar, the concern is that the load could potentially pull more than what the original breaker was sized to allow (since the solar is a second source), so add a second breaker at the load or junction point of the same rating as the original breaker and have the solar connect in between the two breakers.
