Photovoltaic panels rain shielding effect diagram

How do PV panels affect rainfall?

The raindrops intercepted by PV panels during rainfall will concentrate along the lower edges of PV panels and fall onto ground surface, causing heterogeneous spatial distribution of rainfall (Barron-Gafford et al., 2019, Jahanfar et al., 2019). Some researches indicated that runoff in slopes or hillslopes can be increased by PV panels.

Do PV panels prevent soil detachment by raindrop impacts?

The key impact of the PV panel is preventing soil detachment by raindrop impacts. The PV panel slope produced 27 %−63 % less soil erosion than the control slope. The PV panel delayed runoff start time under rainfall with heavy rainfall intensities. PV panels on hillslopes may have the potential to retain soil organic matters. Abstract

Does a PV panel affect rainfall-runoff and soil erosion processes?

The rainfall-runoff and soil erosion processes of a slope with a PV panel above the middle of it and a control slope with no cover were observed and compared. The result indicated that the PV panel did not have considerable effect on runoff volume, peak flow discharge, and overland flow velocity.

Does a photovoltaic panel reduce runoff and sediment in a slope?

The impact of a photovoltaic (PV) panel on runoff and sediment in a slope was tested. The key impact of the PV panel is preventing soil detachment by raindrop impacts. The PV panel slope produced 27 %−63 % less soil erosion than the control slope. The PV panel delayed runoff start time under rainfall with heavy rainfall intensities.

Does partial shading affect solar PV module temperature?

The effect of partial shading on solar PV module temperature under a constant irradiation level of 500 W/m 2 was demonstrated in Fig. 3d. It can be observed from the figure that the solar shading area significantly affects PV module temperature and an increase in the shading area decreases the temperature of the PV module.

Does rain drop interception affect soil function under PV panels?

Meanwhile, as soil structure is important for soil functions (Rabot et al., 2018), rain drop interception of PV panels, which can lead to prevention of soil surface sealing and preservation of surface soil aggregates under PV panels, may attenuate soil function deterioration under the PV panels and promoted vegetation restoration.
