Agrivoltaic facility is the composite system that the solar panel is installed above the farmland, and it enables crop and electricity productionsimultaneously. Solar panels of the agrivoltaic facilities can block and reduce the amount of solar irradiance arriving at the farmland, but it can helpthe crop growth by preventing excessive solar irradiance. Therefore, to clarify how the agrivoltaic facilities affect the crop growth, precise solarirradiance distribution under the solar panel should be modeled. In this study, PAR (photosynthetically active radiation), radiation from 400 to 700 nm,which crops usually use to grow, was extracted from the total irradiance and its distribution model under various conditions was developed. Monthlyirradiance distributions varied because the elevation of the sun was changed over time, which made the position changed that the local maximum andminimum irradiance appear. The higher panel height did not cause any significant difference in the amount of irradiance reaching below the solar panel,but its distribution became more uniform. Furthermore, the panel angles with the most irradiance arriving below the solar panel were different by month,but its difference was up to 2%p between the irradiance with 30° angle which is usually recommended in Korea. Finally, the interval between panelswas adjusted; when the ratio of the length of the panel to the empty space was 1:2, the irradiance of 0.719 times was reached compared to whenthere was no panel, 0.579 times for 1:1 and 0.442 times for 2:1.
Abstract
Agrivoltaic facility is the composite system that the solar panel is installed above the farmland, and it enables crop and electricity productionsimultaneously. Solar panels of the agrivoltaic facilities can block and reduce the amount of solar irradiance arriving at the farmland, but it can helpthe crop growth by preventing excessive solar irradiance. Therefore, to clarify how the agrivoltaic facilities affect the crop growth, precise solarirradiance distribution under the solar panel should be modeled. In this study, PAR (photosynthetically active radiation), radiation from 400 to 700 nm,which crops usually use to grow, was extracted from the total irradiance and its distribution model under various conditions was developed. Monthlyirradiance distributions varied because the elevation of the sun was changed over time, which made the position changed that the local maximum andminimum irradiance appear.
