光伏发电是利用半导体界面的光生伏特效应而将光能直接转变为电能的一种技术。这种技术的关键元件是太阳能电池。
而光热利用按温度可分为中低温和高温利用。中低温主要包括太阳能热水器、太阳能建筑供暖制冷、太阳能海水淡化、太阳能干燥等;高温热利用主要包括太阳能热发电及太阳能热化学等。
目前,太阳能热发电技术主要包括4类,槽式、线性菲涅尔式、碟式及塔式。其中,槽式和塔式太阳能热发电站目前均已实现了商业化运行,而碟式及线性菲涅尔式则分别处于样机示范及系统示范阶段。
光伏发电最大的优势是应用场合没有明显限制,有阳光资源的地方都可安装光伏系统。在辐照不好或者夜间,光伏系统通过对蓄电池进行充放电实现连续运行。
不过,规模化光伏电站若采用蓄电池储能,其成本仍然较高,且蓄电池的使用寿命有待考验。
而太阳能光热利用中除了可以通过材料吸收太阳辐射光谱中不同波长的光能并将其转化为热能供直接使用外,还可以利用聚光器将低密度的太阳能汇聚,生成高密度的能量,加热工作介质,产生蒸汽推动汽轮机发电。聚光器的聚焦方式有点聚焦、线聚焦等,对应产生了碟式、塔式、槽式及菲涅尔式等几种主要的太阳能热发电形式,
与常规火电站相比,太阳能热发电系统的“热—功—电”转换环节所采用的热力循环模式及设备基本是相同的。在辐照连续的条件下,太阳能热发电站可以直接产生与火电站完全相同的满足电网品质要求的交流电,保证电网的电压和频率稳定。
但太阳辐射能本身具有随季节、白天时段不同而不连续变化的特点,受天气条件影响较大。储热材料技术的发展,已为实现规模化稳定运行的太阳能热发电站提供了可能。“在合适的选址区域,带有一定容量储热系统的太阳能热发电站,将不仅可产生满足用户需求的电能,还能根据电网中用电负荷的变化,起到调峰作用”。
另外从实际电站运行的角度来看,太阳能热发电比太阳能光伏发电有对现有火电站及电网系统更好的兼容性。但是,相比光伏发电,对能够体现太阳能热发电经济性所需要的太阳能辐射资源及规模化容量的要求也更高。
光伏是光电的一种,是指利用光伏电池直接将太阳能转化为电能
光热的种类很多,都是利用太阳能的热能,出口方向有太阳能热水器,光热发电,干燥等等
太阳能光热,就利用太阳能,产生热水和发电,不过现在多数都是单独分开的
浙江有一家企业好像在做光热光伏一体的
好像叫 神太 他家研发的光伏热电混合组件PVT可同时发电与发热,综合效率将大幅提升。
也算是一个开端为节能这一块做了很大的贡献
