Analysis of Photovoltaics Performance Under Variable Conditions

Abstract

The basic foundation for obtaining maximum power is reaching the maximum operating point (Maximum Power Point), which makes it the highest possible power produced by the panel in the given irradiance and temperature conditions. Achieving this power requires adjusting the voltage in the work cycle, which unfortunately requires a kind of “search” by “sampling” the value of the instantaneous power at a given voltage. However, it takes a certain time to reach the maximum power, which implies power losses. Another aspect to consider here is the power loss associated with rising temperature (Maximum Power Point shifts towards lower values). Therefore, these two aspects constitute the theme of this work.
