Introduction

The establishment of global power sources depends heavily on renewable energy. The sustainable growth of energy and ecosystems is contingent upon the utilization of solar energy, one among the most significant clean energy sources. Because of its abundance and environmentally beneficial qualities, PV energy is the most significant renewable energy source. Partial shade can be a factor for PV plants, reducing their yield of energy1,2,3,4. Several methods, including the static and dynamic reconfiguration methods, have been brought out to address partial shading5,6. These methods both attempt to increase energy production by minimizing variations in row currents7,8.

A new approach that enables the configuration of the module to be dynamically modified, enhancing its performance in a variety of scenarios. Reconfigurability, in contrast to normal PV modules, ensures a more energy output by mitigating challenges like partial shading. 12% more energy was produced by a full-scale prototype of a reconfigurable PV module under partial shadowing than by a static reference module. By efficiently reducing mismatch losses brought on by shading and module faults the suggested reconfiguration approach maximizes power generation under various conditions9. The research indicates that the solar PV arrays that are shaded, the study shows that the proposed Chaotic Baker Map (CBM) technique significantly enhances energy output. Comparing the CBM technique to conventional techniques such as the TCT arrangement, test results on array sizes of 4 × 4, 6 × 6, and 8 × 8 showed a reduction in power loss of up to 30%. A 25% improvement in energy extraction was obtained by the CBM techniques under particular shading scenarios, incorporating different shading patterns such as T-shaped, corner, and diagonal shading10. The PV array can be dynamically reconfigured for shaded modules in order to increase power output and decrease reverse current owing to the integration of an Insulated Gate Bipolar Transistor (IGBT) model in the proposed design. Nine of the eleven examined cases possessed a consistent decrease in reverse current owing to the modified PV array, showing a notable increase in reliability of 82%. Under several shading environments, the proposed method improves the operating efficiency of PV systems and effectively reduces risks associated with hot spot development11. The authors present a newly developed reconfiguration method that uses the Honey Badger Algorithm (HBA) to arrange PV modules in the most effective possible way to maximize energy efficiency if there is partial shade. The HBA-optimized PV array exhibits a power generation improvement of up to 35% compared to conventional approaches, showing the algorithm’s ability to enhance PV system performance12.

A modified circuit reconfiguration (MCR) technique for partial shadowing conditions (PSCs) using high-concentration PV modules is presented by Huang et al. In comparison to the original series topology, the MCR approach increased power output by about 0.95 W to 4.23 W for square modules and 6.66% to 57.34% for rectangular modules13. Aljafari et al. proposed a hybrid L-shaped circulating array structure is proposed to maximize the energy output if there are partial shadows. Based on quantitative investigation, mismatch losses are greatly reduced using this approach, and power output improvements are observed between 20% and 30% compared to standard arrangements14. The performance of several array topologies, like SP, BL, and TCT, is assessed and compared by Ganesan et al. The Bridge-Linked (BL) configuration works substantially better than the others, as shown by numerical data, which show a power gain of up to 25% in shaded conditions15. Table 1 revealed the assessment of the existing literature with a detailed description.

Table 1 Assessment of the existing literature with a detailed description.

In the specific partial shade conditions and operating parameters assessed in this research, the proposed reconfiguration technique has shown better performance. Conventional topologies like SP, TCT, SP-TCT, and HC-TCT have shown value in reducing mismatch losses, but with more intricate shading patterns, their effectiveness might decrease. On the other hand, given the evaluated conditions, the proposed method delivers a larger energy yield and better power extraction consistency. However, it should be mentioned that these conclusions are based on a comparison with a specific set of current techniques. Recent developments in reconfiguration techniques for photovoltaic (PV) arrays emphasise on maximising the performance in partial shadowing scenarios (PSCs). By contrasting static and dynamic reconfiguration options, the researchers revealed extensive results that indicated that the better dynamic techniques are at reducing shading losses and enhancing energy yield24. The researchers presented a sensorless, zero-switch reconfiguration technique for rooftop PV systems that, without the requirement to incorporate additional hardware, showed an average power enhancement of 19.02% above the existing systems25. The researchers stated an automatic switching technique that dynamically modifies the connections between PV arrays, enhancing maximum power point tracking (MPPT) by up to 30% as compared to conventional techniques26.

The following concisely summarises the work’s main novelties and contributions:

  • A novel quadrant-swapping technique is proposed in this research to enhance the output of the PV array and to enhance the FF by minimizing the ML and PL.

  • For the 10 different types of shading patterns, the experiment was conducted in a PV array (4 × 4 matrices).

  • The effectiveness of the PV system is quantitatively assessed using output power, power loss, mismatch loss, and fill factor.

  • Further, a techno-economic analysis was analyzed to illustrate the potential of the proposed technique.

As compared to the earlier technique of dynamic reconfiguration, the proposed quadrant swapping technique enhanced solar PV systems’ power output. the array’s power output is maximized in the proposed reconfiguration technique using series-parallel connections for a 4 × 4 matrices PV array. PV modules are connected in series to develop a string, followed by the strings being connected in parallel. In industry, it is the most commercially utilized. The proposed quadrant swapping technique increases the fill factor under shading conditions while significantly reducing the ML and PL in terms of performance parameters. The experiment was carried out in a PV array (4 × 4 matrices) for the ten diverse forms of shading patterns for the SP, TCT, SP-TCT, and HC-TCT, and compared with the new proposed quadrant swapping technique.

Experimental setup.

The PV module ratings that were considered are represented in Table 2. The experimental setup for the proposed quadrant swapping reconfiguration strategy is shown in Fig. 2. The irradiation on the module is measured with the pyranometer meter. The switching circuit of the proposed quadrant swapping method is illustrated in Fig. 3(a).

Proposed technique

For enhanced power generation, the proposed quadrant swapping technique is employed to the Series-Parallel based electrical wiring of a 4 × 4 matrix photovoltaic array. PV modules (M11, M12, M13, M14, M21, …, M44) are connected in a series-parallel configuration in Fig. 3a. The PV array is segmented into four quadrants: Q11 and Q12 are quadrant 1, Q21 and Q22 are quadrant 2, Q31 and Q32 are quadrant 3, and Q41 and Q42 are quadrant 4. While shading occurs, the switches (S1, S2, etc.) regulate the power flow to the various quadrants. PV1 is connected to Quadrant Q22 in Fig. 3b (c) by closing S1 and S3. For the other subfigures, a similar logic was applied, and it ensures that the PV module can be allocated to various quadrants as required. To evaluate our proposed quadrant swapping technique under a partial shade environment, the solar PV array is exposed to different levels of irradiation as shown in Fig. 4.

Comparison of payback period.

Techno-economic analysis

One of the main factors influencing a module’s economic significance is its cost. Rodriguez-Gallegos et al. evaluated the Levelized Cost of Electricity (LCOE) of the PV system30,31,32. Table 4 revealed the cost analysis of the PV system under PSCs.

Table 4 Shows the expected cost analysis of the PV system unde PSCs.

The estimated payback period for the module under case (a) is 6 years, moreover, it has been 7 years for SP, TCT, SP-TCT, and HC-TCT. A comparison graph of the payback period for all the cases is shown in Fig. 10. In contrast, the module that uses a proposed technique has a lifespan of 6 years, which is 13.33% higher than the module that uses a conventional SP for case (a).

Conclusion

A Quadrant Swapping Technique has been successfully demonstrated to mitigate power loss in PV arrays and mismatch losses in PV arrays that are subjected to partial shading. Through experimental validation across ten various shading conditions, the approach consistently delivered better performance compared to typical configurations such as SP, TCT, SP-TCT, and HC-TCT. The overall power output, fill factor were all effectively enhanced by the proposed quadrant swapping technique. However, scenario (f) had the highest output power of 136 W, a corresponding FF of 0.57, ML of 2 W, and PL of 1.4%. Conversely, the lowest measured output power was 80 W, with a FF of 0.34, ML of 5 W, and PL of 5.88%. However, from a techno-economic analysis, the lifespan of the suggested method is 6 years, 13.33% longer than that of the module that employs a traditional SP in scenario (a). The findings show that, in comparison with the other configurations (SP, TCT, SP-TCT, and HC-TCT), the proposed quadrant swapping reconfiguration technique is deemed worthy and achieves superior outcomes. This novel technique is applied to large solar power plants to achieve improved output power with less mismatch loss. Further switch reduction may enhance solar PV power output in the future, and grid-connected systems’ array reconfiguration techniques provide an incredible amount of PV system research approaches.
