Solar Energy Potential Assessment in the Algerian South Area : Case of Ghardaïa Region

الملخص EN

Due to its geographical position in the solar belt, Algeria is blessed with an abundance of solar energy and has the opportunity to utilize this bounty of natural energy effectively, promoting a clean environment and developing renewable energy technologies in the region.

This paper assesses and analyses the solar energy potential in Ghardaïa area (south Algeria) to help users for solar energy applications.

A database of solar radiation components has been employed for this purpose.

The data presented in the paper are compared with other data supplied by renowned regional and international establishments, such as the solar atlas for the Mediterranean and the NASA.

The frequency and the hourly distribution of solar radiation components indicate that the region is considered as an economical area and favorable for solar applications, such as the photovoltaic and the concentrating solar power (CSP) technologies.

In addition to solar radiation, data of two functions, namely, clearness index and sunshine fraction have been examined; their results specify that the site has a clear sky conditions in most time of the year.

In general, the obtained results illustrate that the site under consideration can use solar energy as a promising solution to conventional energy.
