Important Solar Parameters in Installing Solar Cells Case study of Zanjan city in Iran

In recent years, due to increasing use of electrical apparatuses, industrial needs for electricity, flexibility of electrical energy and its easy production and distribution, this energy has been called the superior energy. Because of energy security, lack of fossil fuels and global concern for environmental pollution, renewable energy sources are used to generate electrical energy. The sun is the most important source of renewable energies. The average amount of solar radiation to Earth s surface is 8000 times higher than the average energy consumption in the world. According to the amount of solar radiation emitted by the sun to the Earth s surface, per capita of this energy is 20MW. Solar cells are no-noising devices that do not pollute the environment. Due to the lack of moving parts, these equipment have been become a powerful, reliable, lifelong tool. For the reasons mentioned, the use of solar cells is increasing day by day. At the moment, the cost of designing and installing solar systems is high. But these costs are predicted to decline in the future. In this article, the authors have tried to provide a comprehensive overview of the factors affecting the installation of solar cells, such as the location of the installation site and the solar parameters.
