Solar panel yomwe imadziwikanso kuti photovoltaic panel ndi chipangizo chomwe chimatenga kuwala kwa dzuwa ndikusintha mphamvu ya dzuwa kukhala magetsi ogwiritsidwa ntchito. Solar panel imapangidwa ndi maselo angapo a solar (maselo a photovoltaic). Kugwira ntchito bwino kwa solar panel kumadalira mwachindunji kuchuluka kwa maselo a solar.
Module ya photovoltaic imapangidwa ndi ma solar cell, galasi, EVA, back sheet ndi chimango. Makina amakono a solar light amagwiritsa ntchito ma monocrystalline solar panels kapena ma polycrystalline solar panels. Ma monocrystalline solar cell ndi othandiza kwambiri chifukwa amapangidwa kuchokera ku crystal imodzi ya silicon ndipo ma silicon crystals angapo amasungunuka pamodzi kuti apange ma polycrystalline cells. Pali njira zambiri zomwe zimagwiritsidwa ntchito popanga ma solar panels.
Kupanga mapanelo a dzuwa
Pali zinthu 5 zomwe zili mu solar panel.
Maselo a dzuwa
Pali zinthu zambiri zomwe zimagwiritsidwa ntchito popanga maselo a dzuwa. Ma silicon wafers akasinthidwa kukhala maselo a dzuwa amatha kusintha mphamvu ya dzuwa kukhala magetsi. Selo lililonse la dzuwa limakhala ndi positive (boron) ndi negative (phosphorous) charged silicon wafer. Solar panel yachizolowezi imakhala ndi maselo a dzuwa 60 mpaka 72.
Galasi
Galasi lolimba lomwe limatenthedwa limagwiritsidwa ntchito kuteteza maselo a PV ndipo galasi nthawi zambiri limakhala lokhuthala 3 mpaka 4 mm. Galasi yakutsogolo imateteza maselowo ku kutentha kwambiri ndipo idapangidwa kuti isagwe ndi zinyalala zomwe zili mumlengalenga. Magalasi opatsa mphamvu kwambiri omwe amadziwika kuti ali ndi chitsulo chochepa amathandiza kupititsa patsogolo magwiridwe antchito a mapanelo a dzuwa ndipo ali ndi utoto woletsa kuwala kuti apititse patsogolo kufalikira kwa kuwala.
chimango cha aluminiyamu
Chimango cha aluminiyamu chotulutsidwa chimagwiritsidwa ntchito kuteteza m'mphepete mwa laminate yomwe ili m'malo mwa maselo. Izi zimapangitsa kuti pakhale kapangidwe kolimba koyika solar panel pamalo ake. Chimango cha aluminiyamu chimapangidwa kuti chikhale chopepuka komanso chotha kupirira katundu wamakina komanso nyengo yoipa. Chimangocho nthawi zambiri chimakhala chakuda chasiliva kapena anodized ndipo ngodya zake zimatetezedwa pokanikiza kapena ndi zomangira kapena zomangira.
Magawo a filimu ya EVA
Magawo a Ethylene-vinyl acetate (EVA) amagwiritsidwa ntchito kuphimba maselo a dzuwa ndikuwagwirizanitsa panthawi yopanga. Uwu ndi gawo lowonekera bwino lomwe ndi lolimba komanso lopirira chinyezi ndi kusintha kwakukulu kwa nyengo. Magawo a EVA amagwira ntchito yofunika kwambiri poletsa kulowa kwa chinyezi ndi dothi.
Mbali zonse ziwiri za maselo a dzuwa zimakutidwa ndi filimu ya EVA kuti zizitha kuyamwa mafunde komanso kuteteza mawaya olumikizana ndi maselowo kuti asagwe mwadzidzidzi komanso kugwedezeka.
Bokosi la malo olumikizirana
Bokosi lolumikizirana limagwiritsidwa ntchito polumikiza zingwe zomwe zimalumikiza mapanelo mosamala. Ili ndi mpanda waung'ono wosagwedezeka ndi nyengo womwe umasunganso ma bypass diode. Bokosi lolumikizirana lili kumbuyo kwa bolodi ndipo apa ndi pomwe maselo onse amalumikizana, motero, ndikofunikira kuteteza malo apakati awa ku chinyezi ndi dothi.
Ma solar panels nthawi zambiri amakhala kwa zaka pafupifupi 25 mpaka 30 ndipo mphamvu yake imachepa pakapita nthawi. Komabe, sasiya kugwira ntchito kumapeto kwa nthawi yomwe imatchedwa nthawi yogwira ntchito; amachepa pang'onopang'ono ndipo kupanga mphamvu kumachepa chifukwa cha zomwe opanga amaona kuti ndi zochuluka. Chimodzi mwa zifukwa zazikulu zomwe ma solar panels amakhala ndi nthawi yayitali ndichakuti alibe zida zosuntha. Bola ngati sanawonongeke ndi zinthu zina zakunja, ma solar panels amatha kupitiliza kugwira ntchito kwa zaka zambiri. Kuchuluka kwa kuwonongeka kwa ma solar panels kumadaliranso mtundu wa ma solar panels ndipo pamene ukadaulo wa ma solar panels ukukulirakulira pakapita nthawi, kuchuluka kwa kuwonongeka kukukwera.
Malinga ndi ziwerengero, nthawi ya moyo wa solar panel ndi muyeso wa kuchuluka kwa mphamvu zomwe zimapangidwa kwa zaka zambiri poyerekeza ndi mphamvu zomwe solar panel imayesedwa. Opanga opanga solar panel amawerengera kutayika kwa mphamvu pafupifupi 0.8% pachaka. Ma solar panel akuyembekezeka kupanga osachepera 80% ya mphamvu zomwe zimayesedwa kuti zigwire ntchito bwino. Mwachitsanzo, kuti solar panel ya 100 Watt igwire ntchito bwino, iyenera kupanga osachepera 80 Watt. Kuti tidziwe momwe solar panel yanu idzagwirira ntchito patatha zaka zingapo, tiyenera kudziwa kuchuluka kwa kuwonongeka kwa solar panel. Pa avareji, kuchuluka kwa kuwonongeka ndi 1% pachaka chilichonse.
Nthawi yobwezera mphamvu (EPBT) ndi nthawi yomwe solar panel imapanga mphamvu zokwanira kubweza mphamvu zomwe zimagwiritsidwa ntchito popanga solar panel ndipo nthawi yokhalitsa ya solar panel nthawi zambiri imakhala yayitali kuposa EPBT yake. Solar panel yosamalidwa bwino ingayambitse kuchepa kwa kuwonongeka komanso kugwira ntchito bwino kwa solar panel. Kuwonongeka kwa solar panel kungayambitsidwe ndi kutentha kwambiri komanso mphamvu zamakanika zomwe zimakhudza zigawo za solar panel. Kuyang'anitsitsa ma solar panel nthawi zonse kumatha kuwulula mavuto monga mawaya owonekera ndi madera ena odetsa nkhawa kuti solar panel ikhale nthawi yayitali. Kuchotsa ma solar panel ku zinyalala, fumbi, madzi otuluka ndi chipale chofewa kungapangitse kuti solar panel igwire bwino ntchito. Kutsekeka kwa dzuwa ndi mikwingwirima kapena kuwonongeka kwina kulikonse pa solar panel kungakhudze magwiridwe antchito a ma solar panel. Kuchuluka kwa kuwonongeka kumakhala kochepa kwambiri ngati nyengo ili bwino.
Kuchita kwakuwala kwa msewu wa dzuwaZimadalira kwambiri momwe solar panel yomwe imagwiritsa ntchito imagwirira ntchito. Popeza anthu ndi mabizinesi ambiri akuyika ndalama mu mphamvu ya dzuwa, ndikwachibadwa kuyembekezera kuti gawo lofunika kwambiri komanso lokwera mtengo kwambiri la solar street light unit likhale lolimba komanso loyenera ndalama zake. Ma solar panel omwe amagwiritsidwa ntchito kwambiri masiku ano ndi monocrystalline ndi polycrystalline solar panels, omwe onse amakhala ndi moyo wofanana. Komabe, kuchuluka kwa ma solar panel a polycrystalline ndi okwera pang'ono kuposa ma solar panel a monocrystalline. Ngati ma solar panel sanasweke ndipo ngati akupanga magetsi okwanira zosowa zanu, palibe chifukwa chosinthira ma solar panel ngakhale nthawi yawo ya chitsimikizo itatha.
Monga momwe chithunzichi chikusonyezera, Zenith Lighting ndi katswiri wopanga mitundu yonse ya magetsi a dzuwa ndi zinthu zina zokhudzana nazo, ngati muli ndi funso lililonse kapena polojekiti, chonde musazengereze kutero. Lumikizanani nafe.
