| Abstract |
The distributed solar module composition in small size is necessary for simultaneous crop cultivation and power generation in agrophotovoltaic (APV). The purpose of this study is to compare and analyze PV power generation and agricultural environment changes according to different cell string composition (3×12 and 4×9 module). Ground solar radiation was simulated and a test-bed was constructed, with 30% shading rate, to collect monthly power and agricultural environment data for 10 months. The 3×12 module had a 0.7% higher ground solar radiation value than the 4×9 module in the simulation results. In test-bed, though the 4×9 module may be considered for use in the APV in terms of power production, ground solar radiation, and soil humidity, the 3×12 module should be considered that the damage of crops caused by waterdrop can be mitigated when the PV module has fewer strings. These results can contribute for the selection of standard APV module design in terms of installing 10GW of APV by government vision. |
