Njira Zabwino Kwambiri Zothetsera Kulephera kwa Cholumikizira cha Solar PV

     Zolumikizira za Solar PVzimagwira ntchito yofunika kwambiri pakuwongolera ma waya a solar.Monga momwe amapangidwira, amapereka ma voliyumu okwera kwambiri, okwera kwambiri, otsika kwambiri olumikizana ndi DC ngati atayikidwa bwino, ndipo nyumba zawo sizingalowe madzi, sizingatenthedwe, sizingagwirizane ndi UV, ndipo amakhala ndi moyo mpaka zaka 25 kapena kupitilira apo.Kuphatikiza apo, ukadaulo wawo wolumikizana ndi snap-pamodzi umathandizira kukhazikitsa ma solar arrays.Komabe, zolumikizira za PV nthawi zambiri zimakhala gwero la zolephera za solar.

Kafukufuku wa Fraunhofer Institute for Solar Energy Systems ISE waku Freiburg, Germany, adafufuza zomwe zimayambitsa kulephera kwamafuta a PV arrays ndipo adapeza kuti zolumikizira za solar PV ndi ma crimps ndizomwe zidapangitsa kuti ma waya a DC alephereke.Zambiri mwazolephera izi zidachitika mzaka zisanu zoyambirira za kuyika, zomwe zidapangitsa ofufuza kukayikira kuti njira zoyikiratu ndizo chifukwa chachikulu.

Zokambirana kuno ku United States ndi oyendera magetsi zaperekanso chidziwitso chotsatira pakulephera kwa cholumikizira cha PV:

Oyang'anira angapo adawonanso oyika m'munda akusokoneza kulumikizana ndi zolumikizira za PV ndi pulasitala.Ndemanga zowonjezera zidawonetsa "zotayirira" zolumikizira za PV za opanga osiyanasiyana.

Kuphatikizira kulephera kwamitundu yosiyanasiyana ya zolumikizira za solar PV ndikuti zimatha kukhala zovuta kuwona kusonkhana kosayenera komanso ma crimps osalumikizana bwino.Kulephera kwa kulumikizana nthawi zambiri kumabisika pazolumikizira zomwe zikuwoneka kuti zikulumikizana bwino.Pokhapokha cholumikiziracho chili cholakwika kwathunthu, monga cholumikizira chopunduka kapena chosungunuka, ndizosatheka kuchizindikira ndi maso.Kujambula kwa kutentha nthawi zambiri ndiko njira yokhayo yodziwira mavutowa.Kutayika kwa mphamvu, kuzindikira ndi kukonza ndalama zomwe zimagwirizanitsidwa ndi zolephera zobisikazi zingakhale zazikulu.

Zolephera za cholumikizira cha Solar PV zitha kugawidwa m'magulu awiri: zovuta zosagwirizana ndi zovuta zolumikizira zolumikizira.Zolumikizira zokhazikitsidwa ndi fakitale kumbuyo kwa ma module a PV nthawi zambiri sizomwe zimayambitsa mavuto, ndipo zolephera zambiri zimakhudzana ndi mawaya am'munda.Komabe, zolumikizira zoyimitsidwa m'munda monga zomwe zingwe zoyendetsedwa kunyumba zomwe zimagwiritsidwa ntchito ndi chingwe ndi ma inverter ena apakati zitha kukhala zovuta.

Nkhani zosagwirizana nthawi zambiri zimayamba chifukwa cha kuphatikizika kwa zolumikizira za photovoltaic kuchokera kwa opanga osiyanasiyana.Ngakhale zolumikizira zambiri zimawonedwa ngati "zogwirizana," palibe muyezo wamakampani pamapangidwe olumikizira yunifolomu.Chifukwa cha kusiyana kwa kulolerana kwa mapangidwe, zofunikira za zida za crimp ndi kukhudzana ndi zipangizo zapanyumba, kugwirizana kwamagetsi koyenera sikungatsimikizidwe.Kuphatikiza apo, pomwe zolumikizira zonse za PV ziyenera kuyesedwa ku UL 6703, mulingo uwu sumaphimba zolumikizira kuchokera kwa opanga osiyanasiyana pokhapokha atayesedwa mwapadera - china chake sichinachitike kawirikawiri.Opanga ena amachenjeza za kuphatikizika kwa mitundu yolumikizirana yosiyana, ndipo njira zolimbikitsira ziyenera kutsatiridwa.

Zolumikizira zambiri za solar PV zimagwiritsa ntchito mawonekedwe a crimp.Kaya ndi fakitale- kapena kumunda, zolumikizira izi zimafuna chida cha crimp chomwe chimalangizidwa ndi wopanga komanso kuphatikiza koyenera kuti akhazikitse popanda vuto.Zofunikira pakuwongolera zida za crimp ndi malire a crimp die ziyenera kutsatiridwa pakuyika kopanda vuto pa nthawi yonse ya moyo wa solar.Zolumikizira zatsopano za PV zopanda zida ziliponso.zolumikizira izi kuthetsa tooling ndi msonkhano chofunika, iwo ntchito kutentha- ndi kugwedera zosagwira masika kukhudzana kwa mawaya.

Njira yothetsera mavuto a photovoltaic cholumikizira kulephera ndikuwonetsetsa kuyika kolondola panthawi yoyambira mawaya a PV array.Njira zina zabwino zomwe zingagwiritsidwe ntchito kukwaniritsa izi ndi:

Kuphatikiza pa zovuta za kusonkhana koyenera kwa zolumikizira za solar PV, pali nkhani yosagwirizana ndi PV cholumikizira mating.Njira zabwino kwambiri m'derali ndikuphatikiza nthawi zonse kutchula mtundu womwewo wa cholumikizira chapamunda chomwe chimaperekedwa ndi wopanga ma module a PV.Izi zikuphatikiza kugwiritsa ntchito ma microinverters ndi ma optimizers.Ena mwa opanga awa akupanga izi kukhala zosavuta nthawi zina popereka zosankha zamtundu wa PV cholumikizira pazida zawo.

Kugwiritsa ntchito zolumikizira za PV kuchokera kwa wopanga yemweyo, kuphunzitsidwa koyenera, zida zolimbikitsira crimp kapena kugwiritsa ntchito zida zolumikizirana ndi PV zocheperako kungathandize kuchepetsa kulephera kwa cholumikizira.
