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.
Based on the input/output during precipitation events, three different parts of the PV installation can be distinguished: the panel area, the under-panel area and the corridor (Fig. 2a). The water fallen on the impervious panels surface is rapidly drained towards the corridor immediately downstream the panels row.
Most regulatory agencies allow designers to use the drainage characteristics of the vegetated surface under the panels if it has been properly stabilized. The panels are not considered the ground surface, as the water runs off the panel onto the surface below (as opposed to a building, which does not allow stormwater to contact the surface .
(1)Power optimisers are DC to DC converters and if installed at PV modules, they can maximise the electricity output of the PV system by constantly tracking the maximum power point (MPP) of each PV module individually. Power optimisers can also be installed for each PV string or PV array instead of each PV module.

6 FAQs about [Photovoltaic panel drainage process]
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
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.
Does PV panel affect overland flow?
4.1. The effect of PV panel on overland flow The rainfall experiment results showed that the PV panel did not have remarkable influence on runoff volume and peak discharge rate at the slope outlet, although the PV panel on the slope blocked part of the raindrops during rainfall and created concentrated water drops at the lower edge of the panel.
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 rainwater infiltrate a ground-mounted PV system?
Rainwater can generally infiltrate under elevated PV arrays in ground-mounted PV systems, contrary to the common treatment of these facilities as predominantly impervious surfaces that do not allow water to soak into the ground. Many jurisdictions are mistaken in this regard.
