The best approach to build a solar power plant to increase efficiency and location in several climatic climates of Iran using AHP software

Increasing consumption of energy, fossil fuels and resources that replace renewable energies. Due to its location between 25 and 40 degrees north latitude, Iran has the highest ranks in the world in terms of receiving energy. In the geographical location of Iran, the panels should be set in the direction of absolute geographical south so that they are always facing the solar window. The orientation angle of the panels is different in different seasons, and in fixed structures, this angle is adjusted based on the data of the winter season. The detector structures have a 15-30% higher efficiency than the fixed ones; But using it is not economical. Temperature has a significant effect on the efficiency of photovoltaic panels, and exceeding the temperature of 25 degrees Celsius reduces the efficiency. Among the many methods of temperature control, only the method of using phase change materials is economical and can be implemented. Inverters convert direct current into alternating current and it is necessary to use the electricity of the solar power plant. According to the criteria and weights of the effective factors, it was determined by the relevant authorities that sunny days are of special importance among the criteria. Using the Expert Choice software, the AHP method was implemented, and the criterion of the number of sunny days gained the highest importance. Among the five selected points in Kerman city, it was the first priority for the construction of a power plant.
