Statistical analysis of wind and solar energy potential in Tehran

Knowing the potential of wind and solar energy resources is vital to determine significant information of sizing,installing and implementation of renewable energy systems in a given region. The present study identifies wind and solarenergy properties of a studied area located in Tehran, Iran, using input meteorological data measured for one year periodprovided by the Iran Renewable Energy Organization from a ground station, Letman Jungle. Many prior studies are limited inusing average wind speed without classification of the resource. However, the present paper adopts the random fluctuations ofwind speed data for classification purpose. Furthermore, it utilizes a temperature-based method to estimate solar energypotential of the region. In this regard, daily and monthly average amounts of global solar irradiation on horizontal surface arecalculated all around a year. Regarding wind energy resource properties, the most probable wind speed and its direction, thevelocity which carries the maximum energy, the average wind power density, and the wind energy density of the region are allcalculated and discussed. Investigation of the results indicates harnessing solar energy would be more favourable for thestudied region.
