6 FAQs about [The role of photovoltaic panels installed on slope protection]

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.

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

Why did a PV panel erode a slope section?

This was attributed to the weakened splash erosion on the slope section under the PV panel due to the rainfall interception by the panel, which indicated that the key impact of the PV panel was preventing soil detachment by raindrop impacts.

Can solar panels reduce soil erosion?

The experiment results indicated that the PV panel can greatly reduce soil erosion in the slope (especially under heavy rainfall), which implied that, in natural hillslope in arid or semi-arid regions, PV panels may lead to retain organic matter (from plant litter) in the top soil layer under the PV panels.

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.

Can PV panels improve soil structure in hillslopes?

These findings implied that PV panels on hillslopes may have the potential to retain soil organic matter in top soil layers and to improve soil structure (e.g., soil sealing control and soil aggregate protection), which may benefit to hillslope soil conservation and vegetation restoration in long term.
