Recently, renewable resources, are increasingly used for power generation in most countries. Qeshm Island, has significant solar radiation and its required power can be provided by solar power plants. In this paper a technical and economic study is performed and the possibility of providing some required power of Qeshm Island by photovoltaic farms. Due to the variation in the solar radiation, their power generation depends on the solar radiation. In this paper three types of the photovoltaic farms, including fixed panel farms, farms equipped with single and double axis tracker are investigated. The real economical and technical data is used in 2011. The investment, installation and operation costs of photovoltaic farms as well as the penalty of CO2 producing thorough power plants with fossil fuels are considered. After economic evaluation, it is deduced that single axis photovoltaic power plant, is suitable for power providing of Qeshm Island.
