Finding a grid connection can be a serious bottleneck. Rural substations often lack the capacity to export lots of power. And reinforcing capacity or building new lines is expensive. Interestingly this can make it viable to co-locate battery storage at solar sites. This reduces the peak power that is exported and makes the power line cheaper to build. And the battery's can be recharged from the grid if generation is low and used to generate income through storage contracts.
