摘要: The paper presents a technique for parameter estimation of photovoltaic (PV) modules from datasheet information. manufacturer normally provides open-circuit voltage, short-circuit current, maximum power, and voltage at power under the standard test conditions (STC). four values represent targeted performance module. Parameter is formulated as an optimization problem solved by traditional nonlinear programming techniques well global search algorithms. objective to set parameters that minimizes error between computed performance. methodology successfully applied single- double-diode equivalent circuits PV modules. Evidently, need perform prototype lab testing, purpose estimation, eliminated. Results show genetic algorithms (GA) outperform other in obtaining circuit commercially available
