In the existing solar photovoltaic modules, cells are connected in series. The performance of the series-connected module degrades severely during partial shading condition. Further, the use of bypass diode causes multiple peak (local and global peaks) problem. Therefore, total cross tied (TCT) connection has been proposed in this paper to connect the cells in a module (TCT connected module) that gives a better performance during partial shading without multiple peak problem. A novel analytical algorithm is presented in this paper, which will help the photovoltaic installers to estimate the output power of a TCT connected module without using any sophisticated measuring instruments except irradiance and temperature measurement. The proposed analytical algorithm is simple, robust and user friendly, which can be widely used in multidisciplinary research. The output of the proposed model is verified with the simulation and laboratory scale experimental results, which shows less than 4.58% error. Moreover, the proposed algorithm is implemented in 10MW solar plant, which shows around 174.44% performance improvement compared to the existing TCT connected array. Further, the current value of the TCT connected module is very high, which can be effectively used in high current applications such as welding even in partial shading condition.
