How much solar power can be produced on a land surface?
When these conversion limits are applied to observed data sets of solar radiation at the land surface, it is estimated that direct concentrated solar power has a potential on land of up to 11.6 PW (1 PW = 10 15 W), whereas photovoltaic power has a potential of up to 16.3 PW.
What are the limitations of centralized PV power generation?
Centralized PV power generation dominates the PV application market, and research regarding centralized PV development is of great significance. However, there are many limitations that hinder the development of centralized PV. The availability of land resources is a factor that affects PV power development [4, 5].
