About Will rain affect the moisture of photovoltaic panels
Outcomes demonstrate that rain can globally have non-negligible positive benefits on the performances of PV systems, with particular reference to spring/summer periods; in the latter, in fact, the first benefit is related to the strong reduction of thermal losses due to sensible and evaporative cooling, while the second advantage is due to the .

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.
Using Cv as an indicator allows accounting for two sources of spatial heterogeneity: rain redistribution by the solar panels (with eventual local effective rain amounts that exceed the natural rain amounts measured in the control zone) and the sheltering effect of solar panels (with effective rain amounts far lower right under the panels than .
The average soil moisture under the PV panels is similar to that in the non-PV area; however, the shield effect of the PV panels causes an uneven rainfall distribution (Elamri et al. 2018), which increases the local heterogeneity of the soil water distribution and creates more durable water storage under the PV panels (Adeh et al. 2018).
Can Rain Improve Solar Panel Efficiency? Answer: While rain can reduce solar irradiance, it helps clean the panels by washing away dust, dirt, and debris, potentially improving efficiency. Related Articles:

6 FAQs about [Will rain affect the moisture of photovoltaic panels ]
Do PV panels affect soil moisture in the rainy season?
The following results were observed: (1) PV panels had a humidifying effect on soil moisture and the soil moisture had a significant difference in the rainy season, in which the annual average soil moisture of the FIX and OSA PV panel sites increased by 14.7% and 11.1%, respectively, at a depth of 0.1 m.
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.
How does rain affect solar panels?
In more detail and more specifically, the interception of rain by the impervious surface of the solar panels produces an “umbrella effect” that delineates a sheltered area.
Does rain affect the energy production of crystalline photovoltaic modules?
In this sense, numerous studies have been performed in the past decades to assess the influence on the energy production of crystalline photovoltaic modules of several factors, such as spectral quality of solar irradiance, temperature, wind speed, soiling, snow etc. but so far the effect of rain appears scarcely investigated.
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.
How do PV panels affect soil evaporation?
In arid sandy area, lower evaporation and greater soil moisture occur under PV panels, which provides more water for plant growth, thus promoting vegetation recovery and improving vegetation cover; for example, the vegetation coverage at a PV power plant reached 90.5% and effectively protected soil from wind erosion (Liu et al. 2019).
