Before using such energy sources, the very important thing is analysis at the basic level. This paper presents analysis and realization of solar PV system. The current-voltage and power-voltage characteristics of solar PV array changes as parameters like solar insolation, and temperature changes. These characteristics are found and realized by using MATLAB software.展开更多

The indispensability of each form has been studied and is described in this paper. Through analysis of the reliability of the two basic forms, reliability models of the organization management chain in the series connection state and the mixed state of both series connection and parallel connection have been set up.展开更多
