obtained from the nearest Regional Climate Centers or from national insolation da-
tabases such as the National Solar Radiation Database in the United States [5].In
addition, insolation could be calculated according to the method developed in the
Web site [6].
Design considerations
The PV generator must be designed to supply the load safely in smallest Insola-
tion days in winter, and the climatic variations must be taken into consideration in
array reliability.
