Malangizo Osankha Zingwe Zolimba ndi Zolumikizira za Ma Solar Panel Systems
Makina opangira magetsi a dzuwa (PLTS) apangidwa kuti azigwira ntchito kwa zaka zambiri panja, akukumana ndi kutentha, mvula, fumbi, mphepo, ndi kuwala kwa UV tsiku lililonse. Chifukwa chake, kusankha zingwe ndi zolumikizira sikuyenera kutengera mitengo yotsika mtengo kapena "chifukwa choti zimalumikizana." Zingwe ndi zolumikizira zosayenerera zingayambitse kuchepa kwa magwiridwe antchito, kutentha kwambiri, kulephera kwa makina, komanso chiopsezo cha moto. Nkhaniyi ikufotokoza malangizo osankha zingwe ndi zolumikizira zolimba kuti muyike PV yotetezeka, yogwira ntchito bwino, komanso yokhalitsa.
1. Kumvetsetsa ntchito ya zingwe ndi zolumikizira pamakina opangira magetsi a dzuwa
Mu dongosolo la solar panel, mphamvu zamagetsi zimayenda kuchokera pa module (panelo) kupita ku bokosi lophatikiza, chowongolera cha solar charge, kapena inverter, kenako kupita ku batri ndi katundu. Pamalo aliwonse, zingwe ndi zolumikizira zimagwira ntchito zotsatirazi:
- Yendetsani mphamvu yamagetsi ndi mphamvu yotsika kwambiri yomwe ingatayike.
- Imapirira nyengo zovuta kwambiri (UV, kutentha kwambiri, chinyezi).
- Sungani cholumikiziracho chili cholimba kuti chisagwedezeke kapena kutentha.
- Amachepetsa dzimbiri lomwe lingachepetse kukhudzana ndi zinthu.
Cholakwika chofala kwambiri ndikugwiritsa ntchito mawaya amagetsi apakhomo (NYA/NYM) pa chingwe cha DC cha panelo. Komabe, makhalidwe a mphamvu ya DC, malo oyikapo panja, komanso kufunikira kwa kutchinjiriza kwa UV zimapangitsa mawaya apadera a PV kukhala oyenera kwambiri.
2. Sankhani chingwe chapadera cha PV (chingwe cha dzuwa), osati chingwe wamba.
Zingwe za solar panel ziyenera kugwiritsa ntchito zingwe za PV zomwe zimapangidwira kugwiritsidwa ntchito panja komanso DC current. Makhalidwe awo akuluakulu ndi awa:
– Choteteza ku dzuwa chosagwira ntchito: sichimasweka kapena kusweka msanga chifukwa cha dzuwa.
– Kukana kutentha kwambiri komanso kotsika: kumakhala kosinthasintha ndipo sikusungunuka mosavuta.
– Kukana ozoni ndi chinyezi: ndikofunikira kwambiri m'madera otentha.
– Ma conductor osasunthika: osinthasintha komanso olimba kwambiri poyika panja.
Msika, zingwe za PV nthawi zambiri zimadziwika kuti zingwe za PV1-F kapena miyezo yofanana (kutengera dziko/mtundu). Mukagula, yang'anani zomwe zili pa jekete la chingwe: nthawi zambiri imafotokoza kukula kwa mm², kuchuluka kwa magetsi, muyezo, ndi kutentha.
3. Onetsetsani kuti mphamvu ya magetsi ya chingwe ndi yoyenera (DC yokha)
Makina opangira magetsi a dzuwa (makamaka ma inverter a zingwe) amatha kukhala ndi magetsi amphamvu a DC. Ma waya ayenera kuyesedwa mokwanira kuti agwirizane ndi magetsi amenewa. Kuti akhale otetezeka komanso olimba kwa nthawi yayitali:
- Gwiritsani ntchito zingwe zokhala ndi voltage rating yomwe ikugwirizana ndi kapangidwe ka zingwe.
