毕业设计（ 论 文） 论文题目 摘 要 随着当代经济高速发展，社会的进步，地球上的煤、石油、天燃气等自然资源日趋枯竭。传统的火力发电所需要的煤、石油等燃料燃烧将排出二氧化碳和硫的氧化物会导致温室效应和酸雨，恶化地球环境，显然不是长久之计。而现在初具规模的水力发电还远不能满足人们日益生活的需要。这时，寻找新能源迫在眉睫。太阳能是一种干净的可再生绿色能源，越来越受到人们的亲睐。将太阳能转换成电能必将成为未来能源的发展主题。 太阳能发电系统是利用光生伏特效应原理制成的，其组成主要由太阳能电池、蓄电池、控制器和逆变器构成。光伏发电系统可分为独立太阳能光伏发电系统和并网太阳能光伏发电系统独立太阳能光伏发电是指太阳能光伏发电不与电网连接的发电方式，典型特征为需要蓄电池来存储能量，在民用范围内主要用于边远的乡村，如家庭系统、村级太阳能光伏电站；在工业范围内主要用于电讯、卫星广播电视、太阳能水泵，在具备风力发电和小水电的地区还可以组成混合发电系统等。As contemporary the high-speed economic development, social progress on the earth, coal, oil, natural gas and other natural resource is drying up. The traditional coal-fired power need of coal, petroleum and other fuel burning will emit carbon dioxide and sulfur oxide can lead to the greenhouse effect and acid rain, worsen the earths environment, obviously not in the long run. And now taking shape of hydroelectric power is still far from meet the needs of people increasingly life. At this moment, looking for new energy is imminent. Solar energy is a kind of clean renewable green energy, more and more get of people pro-gaze. Solar energy into electrical energy conversion will become future energy development theme. Solar power system is to use effect made of principle, its composition mainly by the solar cells, battery, the controller and inverter to form. Photovoltaic power generation systems can be divided into independent solar photovoltaic power generation systems and grid solar photovoltaic power generation system. Independent power generation is to point to solar photovoltaic solar photovoltaic power generation is not with power grid connection way of generating, typical characteristics for need to store energy storage battery, in civil range is mainly used in remote villages, such as family system, the village-level solar photovoltaic power station; In the industrial range is mainly used in telecommunications, satellite radio and television, the solar energy water pump, wind power and have the small hydropower area still can mi
