太(tai)阳(yang)能发(fa)(fa)电(dian)(dian)(dian)：未来(lai)太(tai)阳(yang)能的大规(gui)模利(li)用(yong)(yong)是(shi)(shi)用(yong)(yong)来(lai)发(fa)(fa)电(dian)(dian)(dian)。利(li)用(yong)(yong)太(tai)阳(yang)能发(fa)(fa)电(dian)(dian)(dian)的式有多种(zhong)。目前(qian)已(yi)的主要有以下两种(zhong)。光(guang) 热 电(dian)(dian)(dian)转(zhuan)换(huan)(huan)。即(ji)利(li)用(yong)(yong)太(tai)阳(yang)所产生的发(fa)(fa)电(dian)(dian)(dian)。般是(shi)(shi)用(yong)(yong)太(tai)阳(yang)能集(ji)热器将(jiang)所吸(xi)收的转(zhuan)换(huan)(huan)为(wei)(wei)工质(zhi)的蒸(zheng)汽(qi)，然(ran)后由蒸(zheng)汽(qi)驱动(dong)气(qi)轮机带动(dong)发(fa)(fa)电(dian)(dian)(dian)机发(fa)(fa)电(dian)(dian)(dian)。前(qian)过程为(wei)(wei)光(guang) 热转(zhuan)换(huan)(huan)，后过程为(wei)(wei)热 电(dian)(dian)(dian)转(zhuan)换(huan)(huan)。光(guang) 电(dian)(dian)(dian)转(zhuan)换(huan)(huan)。其基本原(yuan)理是(shi)(shi)利(li)用(yong)(yong)光(guang)生伏打(da)效(xiao)应将(jiang)太(tai)阳(yang)能直接(jie)转(zhuan)换(huan)(huan)为(wei)(wei)电(dian)(dian)(dian)能，它的基本装置是(shi)(shi)太(tai)阳(yang)能电(dian)(dian)(dian)池。

光(guang)生(sheng)物(wu)利用：通过植物(wu)的光(guang)用来实现(xian)将太阳能转(zhuan)换成为(wei)生(sheng)物(wu)质(zhi)的过程(cheng)。目前主(zhu)要(yao)有速生(sheng)植物(wu)(如薪(xin)炭林)、油(you)料作物(wu)和(he)型海藻。

虽然太(tai)(tai)阳能资源总量相当于现在所利(li)用的(de)能源的(de)万多(duo)，但太(tai)(tai)阳能的(de)能量密度低，而且(qie)它因(yin)地而异，因(yin)时而变，这是开发利(li)用太(tai)(tai)阳能面(mian)临的(de)主(zhu)要问题。

其实关于(yu)对太阳(yang)能(neng)的(de)(de)(de)应(ying)用(yong)，并不是到了这些(xie)年来(lai)(lai)能(neng)源(yuan)问题(ti)日益显现的(de)(de)(de)情况(kuang)下才开始(shi)的(de)(de)(de)，至少在我国，有(you)史可(ke)查的(de)(de)(de)，早(zao)的(de)(de)(de)太阳(yang)能(neng)的(de)(de)(de)利(li)用(yong)可(ke)以归结(jie)到两千多年前(qian)的(de)(de)(de)战国时期，那(nei)个时候(hou)的(de)(de)(de)人们开始(shi)利(li)用(yong)钢制(zhi)四面镜聚焦太阳(yang)光来(lai)(lai)点(dian)火，利(li)用(yong)太阳(yang)能(neng)来(lai)(lai)干燥农副产品。当(dang)然，那(nei)个时候(hou)利(li)用(yong)太阳(yang)能(neng)和现在的(de)(de)(de)太阳(yang)能(neng)开发的(de)(de)(de)目(mu)的(de)(de)(de)不同，但是，作为能(neng)源(yuan)利(li)用(yong)来(lai)(lai)说，无疑都是积的(de)(de)(de)。

电压采集与电池管理

太阳(yang)能(neng)电(dian)池板电(dian)压(ya)采集用于太阳(yang)光线弱的(de)判断，因而可(ke)以作为白天、黄昏的(de)识(shi)别。同时(shi)本系统太阳(yang)能(neng)板反接、反充保护(hu)。

蓄电(dian)(dian)(dian)池电(dian)(dian)(dian)压采集用于蓄电(dian)(dian)(dian)池工(gong)作电(dian)(dian)(dian)压的识别。利用微控制(zhi)器的PWM功能对蓄电(dian)(dian)(dian)池进行充电(dian)(dian)(dian)管理。若太(tai)阳能电(dian)(dian)(dian)池正常充电(dian)(dian)(dian)时蓄电(dian)(dian)(dian)池开路。控制(zhi)器将关断负(fu)载，以(yi)负(fu)载不(bu)被(bei)损,若在(zai)夜间或太(tai)阳能电(dian)(dian)(dian)池不(bu)充电(dian)(dian)(dian)时蓄电(dian)(dian)(dian)池开路，控制(zhi)器由于自身得不(bu)到电(dian)(dian)(dian)力，不(bu)有动(dong)作。

当(dang)充(chong)(chong)(chong)电(dian)(dian)(dian)电(dian)(dian)(dian)压高(gao)于(yu)保(bao)(bao)护电(dian)(dian)(dian)压( V)时(shi)，自(zi)动关(guan)断对蓄(xu)(xu)电(dian)(dian)(dian)池(chi)的充(chong)(chong)(chong)电(dian)(dian)(dian);此后(hou)当(dang)电(dian)(dian)(dian)压掉至维护电(dian)(dian)(dian)压(.V)时(shi)，蓄(xu)(xu)电(dian)(dian)(dian)池(chi)进(jin)入(ru)浮充(chong)(chong)(chong)状态，当(dang)低于(yu)维护电(dian)(dian)(dian)压(. V)后(hou)浮充(chong)(chong)(chong)关(guan)闭，进(jin)入(ru)均充(chong)(chong)(chong)状态。当(dang)蓄(xu)(xu)电(dian)(dian)(dian)池(chi)电(dian)(dian)(dian)压低于(yu)保(bao)(bao)护电(dian)(dian)(dian)压( V)时(shi)，控制器自(zi)动关(guan)闭负载(zai)开关(guan)以保(bao)(bao)护蓄(xu)(xu)电(dian)(dian)(dian)池(chi)不受损(sun)坏。通过(guo)PWM充(chong)(chong)(chong)电(dian)(dian)(dian)电(dian)(dian)(dian)路(智N三阶段充(chong)(chong)(chong)电(dian)(dian)(dian))，可使太阳能(neng)电(dian)(dian)(dian)池(chi)板发挥大，系统充(chong)(chong)(chong)电(dian)(dian)(dian)效(xiao)率(lv)。本(ben)系统蓄(xu)(xu)电(dian)(dian)(dian)池(chi)的反(fan)接(jie)、过(guo)充(chong)(chong)(chong)、过(guo)放。
