Method of probability calculation of spacecraft Solar battery output power at partial shading

In the paper the calculation method of spacecraft solar battery output power at partial shading is presented. The calculation procedure takes into account nonlinear relation between the illuminated square of the battery and its output power caused by the photovoltaic cells connection layout and the voltage-current characteristic of the cell. The procedure uses the data about the relative quantity of the light caught by the battery, an electrical circuit diagram of the battery typical part and the voltage-current characteristic of the photovoltaic cell. The method is based on the principles of the theory of probability and despite of data incompleteness allows to determine the most probable value of battery output power (both instantaneous and time averaged). The solar battery panel simulation gives required data about correlation between the illuminated square of the panel and its output power. In the paper the simulation procedure as well as the way to solve associated equations is offered. The result of the panel sample calculation is presented and qualitative analysis is executed. Also the method to calculate the most probable output power of solar battery on the base of the panel calculation result is offered. The results of the research are applicable to spacecraft solar batteries designing.
