This National Renewable Energy Laboratory page has a cost comparison of utility scale solar farms with rooftop systems:

If you look at the orange portion of the bar for each year (installation labor), you'll see that labor gets paid about 50% more for utility scale farms than for rooftop systems. As of 2023 it's about $0.24 per watt on utility scale systems, $0.18 per watt on rooftops. But the complete rooftop system is much more expensive ($2.70 per watt vs. $1.20 for a large solar farm). The solar farm with one axis tracking will also produce more energy per installed watt over the course of a year. As a result, the cost per kilowatt hour generated from a rooftop solar array is multiples higher than from a utility scale solar farm in the same climate.
