Temperature on PV Module Performance and its Latest Mitigation Techniques: A Review

Abstract

Photovoltaic modules (PVM) output power is sensitive to fluctuations in temperature and the concentration of solar insolation during sustained disclosure. The 20% of solar insolation will be converted into useful electrical energy, while the rest will be dissipated in the form of heat, which in rotate will increase the operating heat of the PVM and it negatively affects the open circuit voltage (Voc), resulting in a decrease in the power alteration productivity and an irreversible rate of cell deprivation. Appropriate cooling techniques are therefore crucial to preserve the operating temperature of the module under standard test conditions (STC). There are two different methods for cooling PVMs, namely active and passive these methods are subdivided into different techniques which are discussed one by one in literature review; in this paper the techniques for cooling PVMs are comprehensively reviewed
