Study on areal solar irradiance for analyzing areally-totalized PV
systems
Solar Energy Materials and Solar Cells, (1997)Abstract
This paper describes the methodology for quantification of solar
irradiance fluctuation in order to analyze the areally totalized
PV systems, which consist of a large number of PV systems connected
to each other in the optimum size of a certain community area. Two
factors quantifying the fluctuation, fluctuation factor and power
spectral density, and some examples are presented. Also cross-correlation
analysis between nine stations? measurements were operated to estimate
the extent of the power fluctuation in a certain area size and to
determine optimum size of the area of areally totalized PV systems.
