Agro Fossil Free - Estimering af solenergipotentiale og dens nytte til kunstvanding ved hjælp af geo-spatial teknologi for at sikre energisikkerhed

General beskrivelse

World development is highly dependent on sustainable utilization of energy resources. Conventional energy generation through fossil fuels is no longer a viable solution to meet ever growing demand. Renewable energy is the key to solve the problems of energy sector due to its potential. In present study, energy demand of the farmers for irrigation purpose is identified through participatory approaches and the data pertaining to existing supply of electricity is obtained from governmental agencies. Solar insolation varies over space depending on the topographic conditions and atmospheric conditions and also based on the day and season of the year. Using the in-situ solar irradiance data, elevation data and land use data, the solar energy potential is estimated for the district of Namakkal, Tamilnadu using geo-spatial technology. The annual average solar potential of the study area is found to be 5.2 kWh/sq.m/day. The study also estimated the cost incurred by an individual in installing 5kW systems and the time period of return on investment. It is found that the study area has enormous potential to tap solar energy and can solve the power crisis in irrigation sector.
