Hourly wages for solar farm construction labor have gone up, but more efficient installation processes and lower cost hardware have compensated for that increase.
The International Renewable Energy Agency says that 191 GW of solar capacity were installed in 2022:
These numbers refer to peak solar panel output under standardized test conditions. The annual output of an installed solar panel depends on how sunny a region is, whether or not the panel tracks the sun, ambient temperature, how much soiling is present on the front glass, and other factors.
Utility scale PV solar farms in the US had an average capacity factor of 24.8% last year:
These solar farms totaled 64.219 gigawatts of peak capacity and generated 139,670 gigawatt-hours of energy, equivalent to running at peak output for 24.8% of the year.
The International Renewable Energy Agency also collates statistics about global electricity generation from renewable energy sources. These numbers take longer to publish than the capacity numbers, since they're more complicated to gather, but you can see the latest update here with numbers for 2021:

Wood Mackenzie estimates that 270 GW of solar will be installed this year:

270/191 = 1.41, or a 41% increase in installed capacity this year.
