Wind force coefficients for photo voltaic arrays placed on slopes

Distributions of scalar velocity ratios

Abstract

In recent years, the large-scale power generations using photovoltaic arrays (Mega solar) are spreading quickly. Although the ground installation type of the Mega solar was main, since the flatland in which large-scale installation of photovoltaic arrays are possible has decreased gradually, it is thought that the installation to a slope will also progress from now on. Then, the wind tunnel experiment using a photovoltaic array model was conducted for the two-dimensional slope, and wind force coefficient which acts on the panel was investigated. Part 1 reports the results about wind velocity distribution around slopes in experiments.
