the amount generated is more relevant. stating capacity is misleading: ofc higher amount generated implies higher capacity.
1gw solar power plant will produce (random numbers) 4gwh in 4 hours per day ( in summer it produces 10gwh in 10 hours per summer day, and 2gwh in 2 hours per winter day, 4 kinda annual average, again, random.. ) so in a year, it produces 4*365= 1460gwh, when 100% uptime, less if there is downtime. fossil for exemple: 1gw fossil plant produces 24gwh per day, thats 8760gwh per year but with 100% year long uptime: 20% downtime->7008gwh only, so on and so forth..stating capacity is misleading, show us productions graphs that could help judge how much generated in said area per year.
