These models have specific strategies for dealing with situations in which understanding human behaviour becomes difficult, i.e. cases of irrationality, and this, in turn, leads to particular methodological consequences. The aim of this article is to illustrate and systematize some of the typical theoretical approaches to the issues of rationality and irrationality and their methodological consequences, while warning, at the same time, against the risks of applying rationality models of a pronounced normative-evaluative nature. A number of important methodological consequences of applying the principle of charity to various degrees of strength are analysed and a taxonomic grid for the different ways of approaching rationality is presented.

Photovoltaic (PV) array meets the total power requirements of the spacecraft in the geostationary orbit during its entire mission life. PV array consists of number of solar panel substrates on which solar cells are laid down in series and parallel for its power requirement generation. This paper presents the effects of varying temperature and irradiance on the solar energy generation based on the fundamental circuit equations of a solar PV cell model. Thus, an increase in irradiance at constant temperature, the voltage and current output also increase. Whereas, at constant irradiance, an increase in temperature decreases the power output from PV array. The model produces various curves for I-V and P-V characteristics of the PV array.
