Productivity Enhancement of Total-Cross-Tied PV Array Under Static Shade Conditions

Mismatch losses, hotspot creation, lower power production, and the occurrence of multiple peaks are the major impacts of the partial shading in a photovoltaic (PV) array. To mitigate the shading effect, this article introduces a Parquet SuDoKu-based static array reconfiguration approach and validates it using an experimental investigation. This concept is initially tested on a 9 × 9 PV array via simulations under five shade patterns before being implemented on a 3 × 3 hardware prototype. In an effort to perform a hardware execution, artificial shade is devised with commercially available polythene sheets and synthetic soiling. This method improved overall efficiency while significantly reducing losses. Also, performance study and a technoeconomic analysis are conducted in support of this assertion.
