Abstract
This paper studies the shadow impact on the loss-of-load probability, the most significant reliability indices, of the photovoltaic power system (PVPS). A suggested index is derived to reflect the shadow impact, denoted by the "Reductive Index". Novel mathematical model is excecuted to estimate the reduction in the daily output energy of PVPS according to this index and the period of shadow continuity. This reduction results in an equivalent reduction in the solar cells array size. So, the maximum permissible reduction in the solar cells array size can be determined on having an arbitrary loss of-load probability level with its change with the installed solar cells array size .
