For example, if 12 V of solar module has 24 solar cells in a series, then 24 V of the solar module will have 48 solar cells in a series (Cucchiella et al. 2017). Similarly, for higher voltages, solar arrays are constructed by connecting a number of solar modules in sequence or parallel. In series, solar cells are linked then the current through them will be the same and if

A photovoltaic combiner box is permitted to be installed on the roof and it is preferred to be as close as possible to the PV modules forming the array. The purpose of the combiner box is to group the wiring from the array into one cable run to other combiners or to the inverter, which reflects the logic of having the combiner box as close as
A dynamic reconfiguration method for electrical connections in a SP connected photovoltaic array under partial shading conditions is presented in Santos Vicente et al.
When we connect N-number of solar cells in series then we get two terminals and the voltage across these two terminals is the sum of the voltages of the cells connected in series. For example, if the of a single cell is 0.3 V and 10 such cells are connected in series than the total voltage across the string will be 0.3 V × 10 = 3 Volts.
A PV array reconfiguration method called SuDoKu has been introduced in [46] to increase the maximum output power under PSC in the PV TCT array. In this study, the physical position of the PV modules in the TCT PV array is rearranged based on the SuDoKu scheme and the results show that placing the PV array modules based on the SuDoKu
Non-uniform irradiance significantly decreases the power delivered by solar photovoltaic arrays. A promising technique for compensating these power losses relies on dynamically reconfiguring the electrical connections between photovoltaic modules.

According to a model-based control algorithm, the output power of the solar PV array increases. In , an adaptive bank scheme has been proposed based on the bubble sort method for shadow dispersion, which requires a continuous change to identify the best-configured array.
Step 1: Note the current, voltage, and power requirement of the PV array Step 2: Note the PV module parameters PV module parameters like current and voltage at maximum power point and other parameters like VOC, ISC, and PM should also be noted. Step 3: Calculate the number of modules to be connected in series and parallel
Sometimes to increase the power of the solar PV system, instead of increasing the voltage by connecting modules in series the current is increased by connecting modules in parallel. The current in the parallel combination of the PV modules array is the sum of individual currents of the modules.
The PV arrays reconfiguration process is performed by all available techniques based on the voltage and current parameters obtained from the PV system, and the combination of these values with the measurement error reduces the performance accuracy of the method used and interfere with the reconfiguration results.
