That depends on where you live. In my area, labor is cheap and the costs of panels, batteries and inverters came down significantly over the last 5 years. You can now break even on electricity costs for a residential pitched-roof installation in under 5 years. This is without any subsidies, without selling anything back to the grid.
Utility-scale solar installations also make a lot of sense, but around here transmission capacity for that is still a massive issue. You can install more transmission capacity, but it's not cheap.

This is arguably a false economy. ~75% of costs for the power grid are not in volume electricity generation, but in maintenance. They haven't priced it that way in most places to encourage power-saving and reduce the need for new infrastructure construction, but they'll be forced to if every roof sprouts solar cells. If volume electricity generation is the concern, doing it in a field is dramatically cheaper than doing it on a roof.
