Egypt Solar BHI Average July[2005-2014] 3km Port Said University

Surface solar irradiation, or daily solar exposure in Egypt in Wh/m2. Direct. July.

10-years average (2005-2014) of monthly mean of daily irradiation received on a horizontal plane (or a plane always facing the sun if DNI).

MINES ParisTech has developed the Heliosat-2 method that converts 15 min Meteosat images into irradiation maps and stores them into the HelioClim-3 database version 4. A monthly irradiation is computed only if at least 25 daily irradiations are valid in the month. To complete the month, the irradiation of a missing day is computed by taking into account the mean value of the valid days and the daily irradiation at the top of atmosphere for this missing day. A day is valid if the database contains at least one 15-min irradiation for this day. Gaps in a day are filled by taking into account the available 15-min irradiation and the 15-min irradiation at the top of atmosphere. The other irradiation components (direct, diffuse) received on an horizontal or plane normal to sun rays are then computed using a published empirical model.

HelioClim-3 data and diffuse and direct components on any plane are provided on the Web via the SoDa Service (www.soda-is.com and pro.soda-is.com) since 2004. Such data are used by academics for teaching and research in solar energy, environment, climate and others, and by companies for the sitting of solar plants (PV, CST), their sizing, and the monitoring of their production.The French company Transvalor is in charge of the SoDa Service and provides also a series of user-tailored services, such as maps similar to those for Egypt.
