Calculator for land area required and units electricity that could be generated by various types of power plants for given Megawatt capacity

The calculator assumes that:
The photovoltaic solar plant is of polycrystalline panels. The panels do not track the sun. The plant is on the ground and not roof top, where the area required is less.
Typical capacity factor= Ratio of actual electricity generation to the generation if the plant would operate at 24x7x365 at its full installed capacity=21% Ref
TYpical area =4 Acre/MW Ref
Typical solar chimney (updraft tower) power plant has
Capacity factor=25% Ref
Area= 49 acre/MW Ref
Typical solar tower power plant eg. PS10 has
Area=13.5 Acre/MW Ref
Capacity factor=24% Ref
Typical solar parabolic trough without natural gas usage eg. solana generating station has
Area=6.8Acre/MW  Ref
Capacity factor=30% Ref
