The first domestically-made solar power plant has been inaugurated as a pilot scheme in Shiraz, Fars province, energy minister said.
Parviz Fattah told IRNA that the ministry used Iranian technology to set up the plant. According to the official, the power plant has parabolic mirrors to direct solar radiation into its solar receivers. With government support, greater investments will be made in renewable energy sources.
Solar energy refers primarily to the use of solar radiation for practical ends. All other renewable energies other than geothermal derive their energy from the sun.
Solar technologies are broadly characterized as either passive or active depending on the way they capture, convert and distribute sunlight. Active solar techniques use photovoltaic panels, pumps, and fans to convert sunlight into useful outputs.
Passive solar techniques include selecting materials with favorable thermal properties, designing spaces that naturally circulate air, and referencing the position of a building to the Sun. Active solar technologies increase the supply of energy and are considered supply side technologies, while passive solar technologies reduce the need for alternate resources and are generally considered demand side technologies.
Iranian agriculture also seeks to optimize the capture of solar energy in order to optimize the productivity of the plants. Techniques such as timed planting cycles, tailored row orientation, staggered heights between rows and the mixing of plant varieties can improve crop yields.
