Can EPA-SWMM model stormwater runoff in ground-mounted photovoltaic solar parks?

A modelling framework for the simulation of stormwater runoff in ground-mounted photovoltaic solar parks is proposed. Elements in the solar park and their mutual interactions during precipitation events are conceptualized in EPA-SWMM. We demonstrate the potential of the framework by exploring how different factors influence runoff formation.

Are solar panels bad for stormwater?

At a high level, the main stormwater issue associated with solar arrays is the concentrated discharge of stormwater runoff at the solar panel drip line, which can act like un-guttered roofs that channelize and accelerate stormwater flow.

Can a water-draining device be clipped to solar panels?

Portuguese startup Solarud has unveiled a water-draining device that can be clipped to solar modules, in order to resolve dust and soiling issues. “The piece is usable on panels that have frame heights of 40 mm, 35 mm or 30 mm, and thickness between 8 mm and 11 mm.

How are solar panels arranged in a ground-mounted solar park?

Panels in ground-mounted PV solar parks are usually placed on a metal frame that is mounted on the ground to hold the panels at a fixed angle. The frame usually can hold more than one panel rows (usually from 2 to 4) in the vertical direction (Fig. 1 a). Panels on the metal frame are then arranged in rows of different length (Fig. 1 b).

Can solar panels be submerged in water?

The exterior of solar panels is pretty well sealed with just aluminum and glass, so solar panels themselves are not a concern when it comes to sitting in water. However, the wiring should not be submerged, and it's generally not recommended to install solar panels on roofs if other options are available.

Why is there ponding under solar panels?

Area of ponding under solar panels due to improper site grading. These concerns are especially significant when the ground surface is a capped landfill that is undergoing a “brownfield to brightfield” conversion through being reused for solar generation deployment.
