Kampani ya Shanghai Qinkai Industrial Co., Ltd., yomwe imapanga komanso kutumiza kunja zinthu zothandizira mawaya, kapangidwe ka chitsulo ndi zida zomangira mphamvu ya dzuwa za mapulojekiti amagetsi ndi zomangamanga, yati yapatsidwa udindo wopereka mphamvu yamagetsi ya boma la Bangladesh, kuphatikizapo ma conduits, zigawo zachitsulo, ma grid plates, kusintha kwa zinthu ndi zina zowonjezera.

Chigawochi chimaika Qinkai mu zomwe gulu lake la uinjiniya limatcha gawo loyendetsera makina ndi chingwe: ziwalo zonyamula katundu pansi pa ma module, njira zomwe zimanyamula ndikuteteza ma DC ndi ma AC cable, malo osungira katundu ndi zitsulo zoyendamo, ndi zida zolumikizirana zomwe zimalumikiza zonse zinayi pamodzi.

"Sitikupereka ma module, ndipo ndicho cholinga chenicheni," kampaniyo inatero m'mawu ake. "Pamalo opangira magetsi a dzuwa, zinthu zomwe zimasankha ngati chomeracho chifika tsiku lolumikizira gridi zili pansi pa ma module. Chitsulo chomwe chimafika ndi mabowo olondola, ngalande yomwe imateteza madzi a mvula kuti asalowe m'zipinda za chingwe, ndi grating yomwe imakhala yotetezeka kuyendamo nthawi yonse ya chomeracho ndi zofunika kwambiri, osati zogwiritsidwa ntchito. Pulogalamu ya boma imagula ma module chifukwa chomwe imagulira ma module: chomeracho sichingagwire ntchito popanda iwo."

Ndondomeko ya malo opangira dzuwa imasankhidwa pansi pa ma modules

Zolemba za ma tender ndi ndalama zogulira zinthu zimakambirana za mphamvu ya ma module ndi mphamvu yoyikidwa. Nthawi yoyika zinthu imayikidwa ndi mafunso ena awiri: ngati ma module akhoza kukhazikika modalirika, komanso ngati zingwe zitha kuyendetsedwa bwino ndikutetezedwa. Zonsezi zimadalira chitsulo ndi ngalande zomwe zafika bwino, momwe zimakhazikitsidwira bwino, komanso ndi zikalata zoyenera.

Ndi mmene Qinkai ananenera kuti cholinga chake pa ntchito ya ku Bangladesh chinali chokhazikika. Magulu asanu omwe aperekedwa si achitsulo ndi zolumikizira mwachisawawa; chilichonse chimakwirira gawo lodziwika bwino la njira yolemerera katundu ndi njira ya chingwe, ndipo chilichonse chili ndi njira yolephera yomwe imawonekera pamalopo osati mu chojambula.

Zimene magulu asanu omwe aperekedwa amachita pamalo opangira dzuwa

• •Ma Conduit — chitetezo cha chingwe ndi kasamalidwe ka njira.Mapaipi amanyamula ndikuteteza mawaya a DC mkati mwa mawaya ndi mawaya a AC pakati pa ma inverter, ma transformer ndi malo olumikizirana, kulamulira ma radius opindika kuti chingwe chisamangidwe pozungulira. Ntchito yawo yachiwiri ndi yoteteza chilengedwe: njira yotsekera, kuletsa madzi kulowa m'malo olumikizirana ndi malo otsetsereka a ngalande kuti atsimikizire ngati madzi akutuluka m'malo olumikizirana afika pachivundikiro cha chingwe.
• •Zigawo zachitsulo — njira yolemerera katundu.Mizati, matabwa ndi zomangira zimasonkhanitsa mphamvu ya mphepo ndi kulemera kwake kuchokera pamwamba pa module ndikuzipereka ku gawo la maziko. Zizindikiro ziwiri zimasankha momwe izi zimagwirira ntchito: kulondola kwa malo a dzenje, komwe kumakhazikitsa liwiro la msonkhano pamalopo, ndi mtundu wa zokutira, zomwe zimakhazikitsa nthawi ya ntchito. Chomera cha photovoltaic nthawi zambiri chimapangidwa kuti chikhale ndi moyo wa zaka 25, ndipo zokutira zotsutsana ndi dzimbiri pa chitsulo chomangidwa ndi momwe chithunzicho chimalemekezedwera.
• •Ma grid plates — malo omwe anthu ndi zida zimatha kuimapo.Njira zoyendetsera zinthu, malo osungiramo zida ndi malo olumikizirana komwe katundu wolemera ayenera kufalikira pamalo okulirapo. Chiwerengero cha katundu chiyenera kufanana ndi katundu wogwiritsidwa ntchito, ndipo kukonza dzimbiri m'mphepete mwa zinthu zodulidwa ndi malo odulidwa pambuyo pa zinthu zoswedwa kuyenera kukhala ndi chitetezo chofanana ndi cha zinthu zoyambira - pamalo enieni, m'mphepete mwa zinthu zodulidwa ndi zoswedwa ndi zomwe zimayambitsa dzimbiri.
• •Zosintha — zida zosakhala zachizolowezi zoyendetsedwa ndi zojambula.Zothandizira zooneka ngati mawonekedwe, zolumikizira zosinthira, zinthu zobowoledwa ndi zopindika zomwe zimathetsa kusiyana kwa nthaka, kupotoka kwa maziko omwe alipo komanso kusinthana kwa makina omwe ali mufakitale, m'malo mozisiya kuti zilumikizidwe, kudula ndi kukakamizidwa pamalopo. Ubwino pano umadalira njira osati zida: kuvomerezedwa kwa zojambula zotsekedwa, kuyang'aniridwa kwa chinthu choyamba komanso kukhazikika kwa batch.
• •Zowonjezera — mawonekedwe otsekera.Zomangira, zolumikizira, zomangira, zotsekera ndi zotetezera kutentha zimakhala ndi mtengo wotsika kwambiri wa unit komanso mwayi waukulu kwambiri woyambitsa mavuto. Zimasankha kufananiza zinthu komwe zitsulo zosiyana zimakumana mu nyengo yotentha komanso yachinyezi ya m'mphepete mwa nyanja, kugwirizana kwa mabowo ndi zigawo zachitsulo ndi mbale za gridi, komanso kukana kumasuka pakagwedezeka ndi mphepo mobwerezabwereza.

Zokonzedweratu kutentha, mvula yamkuntho ndi chimphepo chamkuntho

Bangladesh imaphatikiza kutentha kwambiri ndi chinyezi, miyezi yamvula yamvula yamphamvu komanso kuwonekera kwa chimphepo chamkuntho, kuphatikiza komwe kumafunikira chitetezo cha dzimbiri chachitsulo komanso kukana mphepo kuposa misika yambiri yofunda.

Qinkai adati ili ndi mphamvu yotenthetsera galvanizing (HDG) pazida zachitsulo ndipo imatha kupereka zolemba zoyesera makulidwe a pulasitiki ngati ipemphedwa, ndipo zigawo zazitali zachitsulo zimasamalidwa m'zigawo ndi kulongedza kolimbikitsidwa kuti zichepetse kupindika ndi kupotoka paulendo wautali wa panyanja. Pa njira ya chingwe, tsatanetsatane wa polojekitiyi umakhudza malo olumikizirana a ngalande zotsekedwa ndi komwe kutsetsereka kuti madzi oyenda pamwamba asalowe m'malo otsetsereka.

"Zisankho zokhudzana ndi dzimbiri zimapangidwa kamodzi ndipo zimalipidwa kwa zaka zoposa makumi awiri," kampaniyo inatero. "Wogula amene amachepetsa bajeti ya utoto pa ntchito ya m'mphepete mwa nyanja sakusunga ndalama, koma akungosintha mtengo wake kupita ku nthawi yogwirira ntchito komwe kumakhala kokwera mtengo kwambiri kukonza."

Mtengo wa zinthu zisanu izi zikagulidwa padera

Nkhani yokhudza kutenga chitsulo, ngalande ndi chithandizo cha chingwe kuchokera ku gwero lina nthawi zambiri imatsutsidwa pa mtengo wa unit. Mkangano wa Qinkai umayambira kumbali ina m'malo mwake - kuchokera ku zomwe malo opangira dzuwa ayenera kuchita pamene zipangizo sizikugwirizana ndi kulekerera, kusagwirizana ndi dongosolo kapena kusagwirizana ndi zomwe zafotokozedwa. Kampaniyo inati imayang'ana mndandandawu ndi ogula isananene mawu awa:

•Mabowo omwe sali pamzere amakhala chinthu chogwiritsidwa ntchito pa mzere wa ntchito.Pamene zitsulo ndi zinthu zothandizira chingwe zimapangidwa motsatira mabowo awiri osiyana, kusagwirizana kumeneku kumatsekedwa pamalopo ndi ma reamers, ma shims ndi maola owonjezera a ogwira ntchito - ndipo mfundo yomalizidwayo sigwirizananso ndi njira yolemerera yomwe wopangayo ankaganiza.
•Kusiyanasiyana kwa kupaka kumakhala ngati kupeza dzimbiri, osati vuto lotumiza.Chitsulo chochokera kwa ogulitsa osiyanasiyana chimatanthauza makulidwe ndi kumatira kosiyana kwa chophimba. Pamalo otentha, chinyezi kapena m'mphepete mwa nyanja, kusiyana kumawonekera ngati dzimbiri limatuluka pazitsulo zomangidwa ndi njira zoyendera, zomwe zimapezeka panthawi yowunikira ntchito nthawi yayitali pambuyo poti kuwunika koyambirira kwa kutumiza kwasainidwa.
•Madzi amafika m'chimake cha chingwe kudzera m'malo olumikizirana, osati kudzera m'makoma.Mpope wolumikizana ndi madzi womwe uli ndi mawonekedwe olondola koma wosatsekedwa bwino pa malo olumikizirana ndi malekezero otseguka umayika chotetezera cha chingwe kuti chikhale cholumikizana ndi madzi nthawi zonse — vuto lomwe limawonekera pokhapokha ngati mayeso a chotetezera abwerezedwanso pambuyo pake mu polojekitiyi.
•Mphepete mwa njira zodulira ndi zotchingira ndi pomwe malo oyendamo amayamba kulephera.Kukonza mbale ndi grating popanda kufunikira kokonza m'mbali zodulidwa ndi malo omwe atulutsidwa pambuyo pa weld kumakonza nthawi yokonza pamalo pomwe chophimbacho chili chopyapyala kwambiri.
•Chidebe chodzaza ndi banja chimachedwetsa dongosolo lonse.Kuyika zinthu m'mafakitale komwe kumawoneka bwino — bokosi limodzi la mabulaketi, limodzi la mbale, limodzi la ngalande — kumakakamiza malowo kutsegula ndikukonza chilichonse asanayambe kusonkhanitsa malo amodzi. Mabokosi odzaza ndi zinthu amachotsa sitepe imeneyo.
•Ogulitsa ambiri amatanthauza kuti palibe amene ali ndi mawonekedwe ake.Kulekererana pakati pa bulaketi ya ngalande, gawo lachitsulo ndi mbale sikungatheke kuperekedwa ngati zitatuzi zikuchokera kwa ogulitsa atatu osiyana.

"Chilichonse mwa zinthu zisanu ndi chimodzizo ndi mtengo wa nthawi kapena mtengo wokonza, ndipo palibe chimodzi mwa izo chomwe chimawonekera poyerekeza mtengo wa chinthu chimodzi," kampaniyo inatero. "Ndicho chifukwa chake gawo ili limatchulidwa ngati dongosolo osati ngati mndandanda wazinthu zisanu zogulira."

Chiwerengero cha zaka makumi awiri chimagwiritsidwa ntchito pazinthu zosawoneka bwino kwambiri

Chomera cha photovoltaic nthawi zambiri chimapangidwa kuti chikhale ndi moyo wa zaka 25. Ma module ndi gawo la chomera chomwe chimasinthidwa kapena kusinthidwa; kapangidwe ka chitsulo, chophimba chomwe chilipo ndi njira ya chingwe sizili choncho. Chifukwa chake, zisankho zomwe zimakhala ndi zotsatirapo zazitali kwambiri zimakhala zovuta kuziwona pakagwa kutentha: dongosolo lophimba ndi makulidwe ochepa pa chitsulo chomangidwa, njira yotsekera pamizere yolumikizira ma conduit, kukonza dzimbiri m'mphepete mwa zodulidwa, ndi kuphatikiza zinthu pazolumikizira kuti zitsulo zosiyana zisafulumizitse dzimbiri mumlengalenga wonyowa.

"Zinthu zotsika mtengo kwambiri pa mndandanda wa zinthu nthawi zambiri zimapangitsa kuti ntchito zichitike mwachangu," kampaniyo inatero. "Chomangirira, cholumikizira, ndi cholumikizira. Ndi zinthu zomwe ogula amakonda kugula padera kuti asunge ndalama zochepa. Ndi malonda omwe timakonda kukambirana tisanagule oda kuposa titayamba kugwiritsa ntchito."

Ma track awiri ofunikira akupangidwa ku Bangladesh - ndipo sagula chitsulo chomwecho

Mapaipi a ku Bangladesh si msika umodzi. Akugawika m'magulu awiri ofunikira ndi zinthu zosiyanasiyana, njira zosiyanasiyana zoyendetsera zinthu komanso njira zosiyanasiyana zolembera. Mapulojekiti a pulogalamu yamagetsi - zomera zokhazikika pansi zomwe zimakhala ndi mawaya ataliatali, njira zoyendera, nsanja za zida ndi zofunikira zoperekera - zimagula magawo olemera a zomangamanga, ma grating ndi mawaya ataliatali, motsutsana ndi zojambula zomwe zimazizira miyezi ingapo isanapangidwe. Ntchito yogawa padenga ndi yamalonda ndi mafakitale imachitika nthawi yochepa, yokhala ndi chithandizo chopepuka komanso chokhazikika, magawo ang'onoang'ono a mawaya, komanso kulekerera kochepa kwambiri pakuyika malo.

Njira zonse ziwiri zikuyendetsedwa ndi zolinga zomwezo za ndondomeko. Ndondomeko ya Mphamvu Yobwezerezedwanso ya Bangladesh ya 2025 ikukhazikitsa gawo la 20 peresenti lobwezerezedwanso mu mphamvu zadziko pofika chaka cha 2030 ndi 30 peresenti pofika chaka cha 2040, malinga ndi lipoti la ndondomeko la Julayi 2026 lochokera ku Center for Entrepreneurship Development ku BRAC University, lomwe likuwonetsa kufunikira kwa mafakitale amagetsi oyera ngati chimodzi mwazomwe zimayambitsa cholingachi. Bungwe la nkhani la dziko lonse BSS linanena pa Meyi 7, 2026 kuti boma likuyembekeza kuti 809.5 MW ya kupanga mphamvu ya dzuwa ifike pa intaneti pofika kumapeto kwa chaka cha 2028. Invest Bangladesh, bungwe lolimbikitsa ndalama zadziko lonse, likuwonetsa kuti msika wamagetsi a dzuwa mdzikolo udzafika pa 3.9 GW pofika chaka cha 2030, kukula pamlingo wapachaka wa 38.6 peresenti pakati pa 2025 ndi 2030, motsutsana ndi kuwala kwa dzuwa kwa pafupifupi 5 kWh pa mita imodzi patsiku.

Gawo la padenga la payipi lili ndi ndondomeko yakeyake: atolankhani amalonda aku Bangladesh adalengeza mu Meyi 2026 kuti boma likukonzekera dongosolo latsopano la ndondomeko kuti lifulumizitse kuyika mphamvu ya dzuwa padenga ndikukopa ndalama zachinsinsi, zomwe zidafotokozedwa ndi Dipatimenti Yamalonda ya Shandong Provincial ku China pa June 10, 2026. Akatswiri aku China ali kale gawo lowonekera la ntchito yopereka magetsi. People's Daily idanenanso pa June 25, 2026 kuti fakitale yamagetsi ya Pabna ya 64 MW, yomangidwa ndi katswiri waku China, idafika pa intaneti yolumikizira magetsi mu Julayi 2025 ndipo imapanga magetsi obiriwira pafupifupi 110 miliyoni kWh chaka chilichonse.

Njira ziwirizi zikugwirizana pa funso limodzi lofunika. M'dziko lomwe mvula yamkuntho yakhala ikugwa kwa miyezi ingapo komanso mphepo yamkuntho, chitetezo cha dzimbiri ndi chitetezo cha chingwe ndizomwe zili pamwamba pa zinthu zonse ziwiri, ndipo tsopano onse akuyembekezera zolemba osati chitsimikizo.

"Timatchula ma scope a padenga ndi ma utility-scale kuchokera ku reference yomweyo ya uinjiniya," kampaniyo inatero. "Chitsulo chimapepuka pa ntchito ya padenga ndipo chimalemera kwambiri pa pulogalamu yoyikira pansi, koma chofunikira chopaka utoto, chofunikira chotseka ndi chofunikira cholemba sizisintha. Imeneyo ndi gawo la dongosolo lomwe limapita m'misika yonse iwiri."

Kumene dongosolo limayendetsedwadi

Kugula makina olembedwa kumatanthauza kuti malo owongolera akuwoneka osati osamveka. Qinkai adati oda ya ku Bangladesh imadutsa asanu ndi limodzi mwa iwo, ndipo wogula kapena woyang'anira wachitatu akhoza kukhalapo nthawi iliyonse:

•Kutseka kojambula.Chinthu chilichonse chopangidwa mwamakonda chimatulutsidwa motsatira chithunzi chovomerezeka, ndipo kusinthako kumalembedwa, zinthu zilizonse zisanadulidwe.
•Kuvomerezedwa kwa nkhani yoyamba.Chidutswa choyamba cha chinthu chilichonse chosakhala chachizolowezi chimawunikidwa motsatira zojambula — malo a mabowo, kutalika kwa kudula, ngodya zopindika — gulu lisanayambe. Chinthu choyamba chomwe chikugwirizana ndi chitsimikizo cha khalidwe chotsika mtengo chomwe chimapezeka pa oda yonse.
•Kuyang'anira mkati mwa ndondomeko.Malo a mabowo ndi ubwino wa weld zimawunikidwa panthawi yopangira osati pambuyo pake, kotero kupotoka mwadongosolo kumawonedwa mu gulu loyamba m'malo mwa bokosi lomaliza.
•Kutsimikizira kwa chophimba.Kukhuthala ndi kumatirira kwa chophimba kumayesedwa ndikulembedwa pa gulu lililonse, pa zolemba zomwezo zomwe wogula amalandira.
•Ndondomeko yolongedza ndi kulongedza katundu.Mabokosi amamangidwa ndipo makontena amadzazidwa motsatira ndondomeko yoyika, ndipo dongosolo lonyamulira limaperekedwa asananyamuke kuti malowo athe kukonzekera kulandira zinthu motsatira ndondomeko yoyenera.
•Kuwunikanso zikalata zotumizidwa musanatumize.Zikalata zotsimikizira zinthu, malipoti owunikira ndi mndandanda wa zonyamula katundu zimagwirizanitsidwa ndi kuchuluka kwa zinthu zomwe zatumizidwa chidebe chisanachoke, osati kusonkhana pambuyo pake.

"Malo onse owongolera awa amawononga ndalama zochepa kuposa momwe malo amakonzera," kampaniyo idatero. "Kukonzanso mkati mwa shopu yopangira zinthu kumayesedwa mu maola. Kukonzanso pamalo opangira dzuwa kumayesedwa mu masabata, ndipo kumafika pamalo omwe palibe choyandama chotsala."
