A feasibility study on the application of mesh grids for heliostat wind load reduction

•Perimeter mesh fence reduces heliostat wind loads by up to 50%.•Wind load reduction increases linearly with decreasing mesh fence porosity.•Edge-mounted mesh devices reduce stow and operating wind loads.•Mid-porosity mesh devices reduce operating drag by 15% and lift by 30%•Mesh devices can increase stow drag and operating lift.
