SURVEY OF SOLAR ENERGY USAGES & ITS APPLICATIONS IN LIBYA

Due to its hot climate of Libya, especially in the summer and the length of the radiation of the Sun throughout the year and increasing degree of radiation of the Sun year after year because of other factors, and also the adoption of Libya in power generation on oil and that prices may vary, either as it becomes a large popularity, leading to a rapid depletion in Libya, and either rise, leading to higher energy production costs , It was necessary to use renewable energies of Libya and most of this renewable energy is solar energy. Whereas the annual average solar radiation on a horizontal surface (m2) between 5.5 kWh per day on the coastline of Libya and 7 kWh per day, of southern areas and also a lifetime of sunshine during the year up to approximately 3100 hours in the coastline and 3900 hours to the South. According to this research, the most important objectives required to achieve are production of electricity at the lowest possible cost and environment friendly and take advantage of the massive solar power in Libya.So I have in this research study how to convert solar energy into electrical energy and The expected benefit because of it in Libya, and a focus on cost element in preparation the solar cells, and the most important activities that we can exploit in use of solar energy, and a focus on economic efficiency of solar cells, and also the comparison between the use of solar cells and most stations operating in Libya using fuel oil , We also study solar systems components and factors affecting the performance of the solar cell, and because Libya depends on this heavily, and study of the most important activities and current uses of solar energy in Libya.Accordingly, it was concluded some of the conclusions and recommendations and proposals and some possible solutions that serve this side of the subject.
