工作原理：<br>太陽(yáng)能發(fā)電系統由太陽(yáng)能電池組、太陽(yáng)能控制器、蓄電池（組）組成。如輸出電源為交流220V或110V，還需要配置逆變器。各部分的作用為：<br>太陽(yáng)能電池板<br>太陽(yáng)能電池板：太陽(yáng)能電池板是太陽(yáng)能發(fā)電系統中的核心部分，也是太陽(yáng)能發(fā)電系統中價(jià)值高的部分。其作用是將太陽(yáng)的輻射能力轉換為電能，或送往蓄電池中存儲起來(lái)，或推動(dòng)負載工作。太陽(yáng)能電池板的質(zhì)量和成本將直接決定整個(gè)系統的質(zhì)量和成本；<br>太陽(yáng)能控制器<br>太陽(yáng)能控制器：太陽(yáng)能控制器的作用是控制整個(gè)系統的工作狀態(tài)，并對蓄電池起到過(guò)充電保護、過(guò)放電保護的作用。在溫差較大的地方，合格的控制器還應具備溫度補償的功能。其他附加功能如光控開(kāi)關(guān)、時(shí)控開(kāi)關(guān)都應當是控制器的可選項；<br>蓄電池<br>蓄電池：一般為鉛酸電池，小微型系統中，也可用鎳氫電池、鎳鎘電池或鋰電池。其作用是在有光照時(shí)將太陽(yáng)能電池板所發(fā)出的電能儲存起來(lái)，到需要的時(shí)候再釋放出來(lái)。<br>逆變器<br>逆變器：在很多場(chǎng)合，都需要提供220VAC、110VAC的交流電源。由于太陽(yáng)能的直接輸出一般都是12VDC、24VDC、48VDC。為能向220VAC的電器提供電能，需要將太陽(yáng)能發(fā)電系統所發(fā)出的直流電能轉換成交流電能，因此需要使用DC-AC逆變器。在某些場(chǎng)合，需要使用多種電壓的負載時(shí)，也要用到DC-DC逆變器，如將24VDC的電能轉換成5VDC的電能（注意，不是簡(jiǎn)單的降壓）。<br>影響因素<br>太陽(yáng)能發(fā)電系統的設計需要考慮如下因素：<br>Q1、太陽(yáng)能發(fā)電系統在哪里使用？該地日光輻射情況如何？<br>Q2、系統的負載功率多大？<br>Q3、系統的輸出電壓是多少，直流還是交流？<br>Q4、系統每天需要工作多少小時(shí)？<br>Q5、如遇到?jīng)]有日光照射的陰雨天氣，系統需連續供電多少天？<br>Q6、負載的情況，純電阻性、電容性還是電感性，啟動(dòng)電流多大？<br>Q7、系統需求的數量。<br><img

alt="濟南太陽(yáng)能施工警示燈"/><br>太陽(yáng)能燈由太陽(yáng)能電池組件、部分LED燈具、控制箱(其控制箱內有充電器、控制器、蓄電池)和燈桿幾部分構成。太陽(yáng)能電池板光效達到127Wp/m2，效率較高，對系統的抗風(fēng)設計非常有利；燈頭部分以1W白光LED和1W黃光LED集成于印刷電路板上排列為一定間距的點(diǎn)陣作為平面發(fā)光源?？刂葡湎潴w以不銹鋼為材質(zhì)，美觀(guān)耐用；控制箱內放置免維護鉛酸蓄電池和采用慢脈沖快速充放電專(zhuān)利技術(shù)研制成功的太陽(yáng)能路燈專(zhuān)用充電控制器。系統選用閥控密封式鉛酸蓄電池，由于其維護很少，故又被稱(chēng)為“免維護電池”，有利于降低系統維護費用；充放電控制器在設計上兼顧了功能齊備(具備光控、時(shí)控、過(guò)充保護、過(guò)放保護和反接保護等)與成本控制，實(shí)現很高的性?xún)r(jià)比。<br><img

alt="濟南太陽(yáng)能施工警示燈"/><br>采用PC面罩，近年來(lái)也稱(chēng)為有機玻璃，有機玻璃的面罩區別于普通玻璃面罩大的優(yōu)點(diǎn)在于：它可以熱彎成任意弧形，弧形成型的比平面的玻璃面罩更有效的避免光線(xiàn)反射，有效聚光。也更能夠防塵。<br><img style="margin: auto;clear: both;display:
