摘要作者在低调的，屋顶安装的太阳能阵列上检查了风，通过在边界层风洞中使用比例模型，放置在大型的低层建筑物上。典型的设计曲线上的几何形状，典型的设计。建筑物的尺寸导致曲线塌陷到每个阵列几何的单个曲线上。 °或以上，风荷载不显着取决于倾斜角度，并且相对恒定。在阵列倾斜角度。
AbstractThe author examined wind loads on low-profile, roof-mounted solar arrays, placed on large, low-rise buildings with nearly flat roofs by using scale models in a boundary layer wind tunnel. The author also examined the effects of building size and array geometry on enveloping curves of area-averaged pressure coefficients, typical of use for design. It was found that wind loads on the array increase with building size; normalizing the effective wind area by the building wall size leads to enveloping curves that collapse onto a single curve for each array geometry. For tilt angles less than 10°, there is an approximate linear increase in the pressure coefficients as the tilt angle increases. For arrays with tilt angles of 10° or more, the wind loads do not depend significantly on the tilt angle and are relatively constant. Roof zones for wind loads on solar arrays are larger than roof zones for bare roofs and depend on the array tilt angle.
