Abstract


In this paper a new configuration of PV array (of size 145 Wp), which is a hybrid of total-cross-tied and series (TCT-S), has been designed and studied. TCT-S array has series configuration at module level and total cross tied configuration at cell level.   Experimental investigations in real field conditions have been conducted on the novel hybrid array without and with bypass diodes under unshaded and partial shaded conditions. The results have been compared with the conventional pure series configuration of PV array.  Twelve distinct partial shading conditions, ranging from only a single shaded cell in the entire array to partially shading all the modules within the array have been considered for this work. The output power, power loss, utilization factor and power enhancement of the proposed configuration is investigated without and with bypass diode under the considered partial shading scenarios. The maximum enhancement achieved by proposed novel configuration of PV array in comparison to conventional array, is 55.4 % and 62.8 % without and with bypass diodes respectively. Moreover, it is also observed that in the absence of bypass diode, while the conventional array output power is dragged down to zero with only one cell failure, the proposed TCT-S array can still generate approx. 90 % power.
