Productivity Enhancement of Total-Cross-Tied PV Array Under Static Shade Conditions
Nikita Ramachandra, N. Rajasekar
Abstract
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.
