Economic optimization of irrigation channel coating with solar panels based on energy receiving angles (case study: Noruzlu Dam's water channel)

Considering the consequences of climate change and the existence of drought, the current conditions should be managed in such a way that the spread of the negative effects of these changes, including the reduction of water resources in open water transfer systems through evaporation, is limited and controlled. Evaporation from the surface of open channels, especially in arid and semi-arid areas like Iran, needs more detailed studies; Therefore, in the present study, the factors affecting evaporation were first investigated based on the data received by the Meteorological Organization, and then the potential amount of solar radiation was estimated in the area of the water supply channel on the right bank of the Noruzlu Diversion Dam, and the amount of coverage of the channel surface was investigated. . For this purpose, the required data were extracted through the meteorology software and using the RCP 2.6, RCP 4.5 and RCP 8.5 scenarios. Based on the research findings, the decrease in the radiation potential and the gradual increase in temperature and as a result the global warming revealed.In the continuation of this process, by entering the extracted data into the PVC system software, different angles of the radiation effect and simulating the shading scenarios of the panels at different distances were carried out in order to choose the optimal angle with the maximum amount of energy received. As a result, the slope angle is 37 degrees with the water supply channel coverage of about 67% in the covered area of about 24,763 of the 36,960 square meters of the canal, 7,377 megawatt hours of electricity energy annually at a cost of about 82 billion tomans and annual income of 6.5 billion tomans with return on investment 12.4 years was selected.
