Various statistical data for different weather condition obtained using metrological reports can be used to analyze and predict the feasibility to set up a standalone photovoltaic system at different geographical locations. Various steps involved in modeling the performance of photovoltaic systems include the physical parameters of the surrounding environment that helps in determining the output power generated. For any standalone system, a design and installation at best location is required to predict the optimal renewable energy capabilities. In this paper we intend to analyze the solar irradiation for a specific period through which we can calculate DC power generated. Solar parameters, power parameters and the Power Loss parameters are determined using system advisor model (SAM) which in turn helps us to predict the actual power generated. This virtual simulation facilitates the initial design consideration to set up a standalone power plant. The gross energy yield is obtained considering all losses and this supports to calculate the output power for a given solar module.
