Ungazikhetha kanjani izibani zasemgwaqweni zelanga?

Njengomuntu embonini, ngifingqe izici eziningana. Uma ngikhetha lezi, ngingakhetha imikhiqizo eyanelisayo.

1.Ukuze uqonde izingxenye ze-LED zesibani somgwaqo selanga, kunezinhlobo eziningi zezingxenye ezinemininingwane eminingi, ikakhulukazi okuhlanganisa amaphaneli elanga, amabhethri, abalawuli, imithombo yokukhanya nezinye izingxenye ezihambisanayo.

Zonke izinto zokwengeza zinezinto eziningi ezingashiwo. Ngizozifingqa lapha.

Amaphaneli elanga: ama-polycrystalline kanye nama-single crystal avamile emakethe. Kungahlulelwa ngokuqondile ngokubukeka. Ama-70% emakethe angama-polycrystalline, anezimbali zeqhwa eziluhlaza okwesibhakabhaka ekubukekeni, kanti ama-single crystal anombala oqinile.

Nokho, lokhu akubalulekile kakhulu. Phela, lezi zibili zinezinzuzo zazo. Izinga lokuguqulwa kwe-polycrystalline silicon liphansi kancane, futhi ukusebenza kahle kokuguqulwa kwamaseli e-monocrystalline silicon kuphakeme cishe ngo-1% kune-polycrystalline silicon. Kodwa-ke, ngoba amaseli e-monocrystalline silicon angenziwa kuphela abe yizikwele ezi-quasi (zonke izinhlangothi ezine ziyizingqimba eziyindilinga), lapho kwakhiwa amaphaneli eseli lelanga, ezinye izindawo zizogcwaliswa; i-Polysilicon iyisikwele, ngakho-ke ayikho inkinga enjalo.

Ibhethri: Kunconywa ukuthi uthenge ibhethri le-lithium iron phosphate (ibhethri le-lithium). Elinye ibhethri le-lead-acid. Ibhethri le-lead-acid alimelani nokushisa okuphezulu, okulula ukubangela ukuvuza koketshezi. Ibhethri le-lithium limelana nokushisa okuphezulu, kodwa alimelani nokushisa okuphansi. Izinga lokuguqulwa liphansi ekushiseni okuphansi. Uyabona ukukhetha kwesifunda. Ngokuvamile, izinga lokuguqulwa kanye nokuphepha kwamabhethri e-lithium kuphakeme kunelawo amabhethri e-lead-acid.

Ukusebenzisa ibhethri le-lithium iron phosphate, isivinini sokushaja nokukhipha sizoshesha, isici sokuphepha sizoba phezulu, sihlala isikhathi eside kunebhethri le-lead-acid elihlala isikhathi eside, futhi impilo yalo yokusebenza izohlala isikhathi eside cishe ngokuphindwe kasithupha kunebhethri le-lead-acid.

Isilawuli: kunezilawuli eziningi emakethe manje. Mina ngokwami ​​ngincoma ubuchwepheshe obusha, njengokulawula i-MPPT. Njengamanje, isilawuli se-MPPT esingcono eShayina yisilawuli selanga esikhiqizwa ubuchwepheshe be-Zhongyi. Ubuchwepheshe bokushaja be-MPPT benza ukusebenza kahle kohlelo lokukhiqizwa kwamandla elanga kube ngu-50% ngaphezu kolwendabuko ukuze kufezwe ukushaja okuphumelelayo. Lusetshenziswa kabanzi ezinhlelweni zasekhaya zezibani zasemgwaqweni zelanga ezincane neziphakathi kanye nezitshalo zamandla elanga ezincane neziphakathi. Ngenxa yekhwalithi ephezulu kanye nokusebenza kwayo, inesabelo esikhulu kakhulu emakethe ye-photovoltaic yasekhaya.

Umthombo wokukhanya: khetha ubuhlalu bezibani obusezingeni eliphezulu, obuthinta ngqo ukukhanya nokuzinza kwesibani, okuyinto ebaluleke kakhulu. Kunconywa ubuhlalu bezibani zeRiya. Ukusetshenziswa kwamandla kungaphansi ngo-80% kunezibani ze-incandescent ezinokukhanya okufanayo. Umthombo wokukhanya uzinzile futhi uyafana ngaphandle kokukhanya, ukusebenza kahle kakhulu nokonga amandla, ukushisa okuphansi, ukukhishwa kombala okuphezulu, impilo yesevisi ende kanye nokusebenza kahle okuphezulu kokukhanya. Ukukhanya kwansuku zonke kuphindwe kabili kunokwezibani zomgwaqo zendabuko, kufika ku-25LUX!

2.Igobolondo lesibani: i-hot galvanizing kanye ne-cold galvanizing kuvamile emakethe, okungahlulelwa ngamehlo enyama. I-hot dip galvanizing isene-coating e-notch, kanti i-cold galvanizing ayina-coating e-notch. I-hot dip galvanizing ivamile emakethe, okuyinto engelula ukuyikhetha. Isizathu esiyinhloko ukuthi i-hot dip galvanizing ilwa kakhulu nokugqwala futhi ilwa nokugqwala.

3.Ukubukeka: ukubona i-LED iyonke yesibani somgwaqo selanga kuwukubona ukuthi ukuma kanye nokusebenza kwesibani somgwaqo selanga kuhle yini nokuthi ngabe kukhona yini inkinga yokugoba. Lesi yisidingo esiyisisekelo sesibani somgwaqo selanga.

4.Naka iwaranti yomkhiqizi. Njengamanje, iwaranti emakethe ngokuvamile ingunyaka ongu-1-3, kanti iwaranti yefektri yethu ingunyaka ongu-5. Ungachofoza iwebhusayithi ukuze ungibuze futhi ungithinte. Zama ukukhetha eyodwa enesikhathi eside sewaranti. Buza ngenqubomgomo yewaranti. Uma isibani siphuka, umenzi angasilungisa kanjani, ukuthi asithumele yini esisha ngqo noma asithumele esidala emuva ukuze silungiswe, ukuthi singabala kanjani imithwalo, njalo njalo.

5.Zama ukuthenga izimpahla kumkhiqizi. Iningi labathengisi abahlala kwezentengiselwano ze-e bangabantu abaphakathi, ngakho-ke kufanele sinake ukuhlola. Ngenxa yokuthi umuntu ophakathi angashintsha eminye imikhiqizo ngemva konyaka owodwa noma emibili, kunzima ukuqinisekisa isevisi yangemva kokuthengisa. Umkhiqizi ungcono kakhulu. Ungathumela igama lomkhiqizi ebhizinisini bese ulihlola ukuze ubone ukuthi ingakanani imali ebhalisiwe yomkhiqizi. Imali ebhalisiwe yezibani zasemgwaqweni incane kakhulu, kusukela kumakhulu ezinkulungwane kuya ezigidini, kanye namashumi ezigidi. Uma unaka ikhwalithi futhi udinga izibani zasemgwaqweni zelanga ezinekhwalithi ephezulu nokuphila isikhathi eside kwenkonzo (iminyaka engu-8-10), ungachofoza iwebhusayithi ukuze ubuze futhi ungithinte. Ikakhulukazi kwezobunjiniyela, zama ukukhetha abakhiqizi abanemali ebhalisiwe engaphezu kwezigidi ezingu-50.
