Jordan is a country with highly fossil fuel deficiency and thus other energy sources are needed to be explored. Solar energy in Jordan is highly recognized as a good source of energy and an excellent substitute to the fossil fuel. The solar energy in this article is obtained via data bases and modeling techniques for the specified place coordinate and angle of inclination. The angles of sun irradiations are different throughout the year; therefore solar energy needs to be magnified by optimizing the angle of inclination of solar cells. In this research, the optimized angles throughout the year are obtained to be in the range: 10°-60°. Solar energy can serve the residential building, the findings of this research show that every 1 m2 of the solar cell may contribute to about 60%-70% of customer needs of electricity throughout the year. The application of solar energy concept in the design of building will play an important role in energy sustainability.
