A fast MPPT technique based on I-V curve characteristics under partial shading

This paper has proposed a new MPPT scheme to speed up the global peak searching process under partial shading. In this scheme, characteristics of I-V curve is critically analyzed to design an intelligent mechanism. Through that, several sections of the curve can be easily avoided from scanning as th...
