Where the article explains it
Writing energy generated as E over a period t across area A , with nameplate capacity C and capacity factor f :
The passage around this formula
The second confusion is with capacity factor . Power density is an area-normalised output rate; capacity factor is a time-normalised one. They multiply rather than substitute. Writing energy generated as E over a period t across area A , with nameplate capacity C and capacity factor f :
Learn the underlying idea
A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
