Total Cross Tied-Inverted Triangle View Configuration for PV System Power Enhancement

Abstract

Electricity can be generated from a photovoltaic cell depending on the amount of solar radiation received from the solar system. But due to some factors such as partial shade conditions, as the thickness of the shade increases, the peak power output from the solar photovoltaic system decreases. Photovoltaic cells can be connected in parallel and in series to generate the required voltage and power. Peak power can be obtained even under shade conditions using the appropriate configuration of solar cells. A novel configuration as Total Cross Tied-Inverted Triangle View (TCT-ITV) is developed in the research by augmenting the Total Cross Tied configuration with Inverted Triangle configuration. The above system is simulated in MATLAB/SIMULINK and the performance of the system is extensively studied. Experiments have been performed under a different shading structure with the proposed TCT-ITV and compared with the existing topologies available in the literatures such as S, SP and TCT configuration, SuDoKu, magic square view topologies. It is evident from the results that the generated power using the proposed configuration increases by 7.89%, thus proving to be more efficient than the existing schemes. It can be claimed that the proposed topology performs better under large wide shaded conditions and hence used in various applications.
