Design of a standalone PV system for the all-weather condition: A practical approach

Abstract

In recent times, many researchers have presented various works on the design of standalone PV(SPV) systems. Though from the review of certain works on SPV systems, it was noted that various critical parameters were not considered for the design of the system. In the present work, a detailed design of a standalone PV system based on a practical approach for the all-weather condition is proposed. Generation of power through SPV includes designing, identifying, and determining specifications of various components being used in the system based on the load estimation. The process mentioned earlier mainly depends on factors like, geographical location, type of weather conditions, insolation level of sun, and finally load consumption. Here a detailed outline for the procedure specifying all the components of the standalone photovoltaic system for all-weather conditions based on typical energy requirements is considered. The paper also presents an elaborate cost analysis considering the entire life span of solar PV module installation and maintenance is also considered. The analysis highlights the high initial investment but also presents the ROI amount and substantial dividend gains during the system life span. Thus the presented will act as a helpful resource for designing and installing the SPV for rural and urban areas.
