| Abstract | Electricity is so important that we use it in various fields of human activity every day. Indeed, we cannot even dream of living in absence of electricity in modern times and the use of electricity is increasing day by day. Global solar radiation has the potential to meet all of our energy requirements and the recent installation growth rates in the PV sector have demonstrated the potential benefit. One of the most important parameters that affects Photovoltaic (PV) panel system is solar radiation received from the Sun. Because both position and angle of a PV panel are important factors in PV system design, they are considered in many numerical analyses in this thesis. Investigation the optimal tilt angle of PV panels in this thesis uses a mathematical method, the forecasted solar radiation in different tiled and azimuth angles, and the satellite data of monthly average daily solar radiation and diffuse solar radiation on horizontal surface of 10 years. Using monthly average daily optimal tilt angle can increase the received energy than using the optimal yearly tilt angle. However, for rooftop installations, the module mounting system selected is dependent on the roof type and the structural characteristics of the building. Sun tracking systems are also possible, but these are more common in the ground mounted installations. They are typically more expensive and technically complicated and require additional maintenance. |
