Njengoba izinhlelo ze-photovoltaic (PV) ezisatshalaliswayo zamukelwa kabanzi, ngenxa yezinqubomgomo zikahulumeni kazwelonke nowendawo, ukuqinisekisa ukuthi amanzi angangeni ngesikhathi sokufakwa sekuyinkinga enkulu. Njengoba lezi zinhlelo zisesesigabeni sokuqala sokwamukelwa emakethe, ukuhlukahluka komklamo kanye nekhwalithi yokwakha kungabangela ukuthi amanzi angangeni, okuholela ekuvuza okungalimaza kokubili uhlelo lwe-PV kanye nesakhiwo sesakhiwo. Nasi ukubheka kabanzi ukuthi ungaqinisekisa kanjani ukuthi amanzi angangeni ngesikhathi sokufakwa ayasebenza.
Izimiso Ezijwayelekile Zokuvimbela Ukungena Kwamanzi Ezindongeni Zophahla
Isimiso esiyinhloko sokuvimbela amanzi ophahleni ukuthi "qondisa, ungavimbi," okusho ukuthi amanzi kufanele akwazi ukuphuma kahle ngaphandle kokuhlanganisa, ngisho nangesikhathi semvula enkulu, ukuqinisekisa ukuthi uphahla luhlala lungavuzi.
Ezimweni lapho kudingeka kubholwe khona imigodi ophahleni olukhona, indlela yokuvimbela amanzi kufanele ihambisane nezimo ezithile. Ake sihlaziye indlela yokusingatha izinhlobo ezahlukene zophahla.
Ukuvikela Uphahla Oluyisicaba
Kumaphahla asanda kwakhiwa ayisicaba ekhonkrithi, amabhawodi kufanele afakwe ngesikhathi sokuklama, futhi ukuvimbela amanzi kufanele kulandele izindlela ezijwayelekile. Ezakhiweni ezikhona, lapho kufakwa izisekelo ze-PV module, ungqimba lokuvimbela amanzi kufanele ludlule phezu kwesisekelo kanye nezinamathiselo zensimbi, kanye nokuvala okuzungeze amabhawodi e-anchor. Kufanele kusetshenziswe i-sealant engangeni manzi lapho kungena khona amanzi, futhi kunconywa ungqimba olwengeziwe olungangeni manzi ngaphansi kwesisekelo. Lolu ngqimba olwengeziwe luqinisekisa ukuthi noma ngabe kukhona ukuvuza esisekelweni, amanzi ngeke afinyelele ungqimba lwesakhiwo.
Ukusetshenziswa Kwezikhonkwane Zamakhemikhali
Kumaphahla ayisicaba akhona ekhonkrithi, uma kusetshenziswa izikhonkwane zamakhemikhali ukuqinisa uhlaka, ubukhulu bengqimba yokuvikela noma yobuso kufanele buqinisekiswe kuqala. Uma kwenzeka uphahla lweslabhu olubunjiwe kusengaphambili olunezidingo ezisindayo zokuthwala imithwalo, ungqimba lwekhonkrithi olwengeziwe lungathululwa. Uma selulungisiwe, uhlaka lungalungiswa kusetshenziswa izikhonkwane zamakhemikhali.
Kumaphahla agudle amathayela, kubalulekile ukuhlola ukujula kwemigodi ebholiwe. Ngemva kokulungisa ama-chemical anchors, indawo lapho i-anchor ingena khona amathayela kufanele ivalwe nge-sealant engangeni manzi. Ama-chemical anchors anikeza izinzuzo ezifana nomthamo ophezulu wokuthwala umthwalo, ukumelana nokukhathala, kanye nokumelana nokuguga, ngaphandle kokusebenzisa amandla okukhulisa ku-substrate. Lokhu kusho ukuthi ngeke kube nomthelela omubi ekuvinjweni kwamanzi kophahla.
Ukuvikela Uphahla Lwensimbi
Ophahleni lwensimbi, isakhiwo sensimbi sohlelo lwe-PV kumele singene ungqimba lokuqala olungangeni manzi kanye nepuleti lensimbi elinomfanekiso, silibophe esakhiweni sensimbi esiyinhloko sesakhiwo. Ngokulandela imikhuba ejwayelekile yokuvikela uphahla lwensimbi, kusetshenziswa izithiyo zomusi, ukuvikela umswakama, kanye nokwelashwa kokuvikela ukungcola. Izinyathelo ezibalulekile zifaka phakathi ukususa ukugqwala, ukuvala, kanye nokufaka izembozo ezingangeni manzi esisekelweni nasezindaweni ezizungezile.
Uma kuvuza ophahleni lwensimbi endaweni, kufanele kusetshenziswe i-sealant esezingeni eliphezulu engangenisi zinkinga zezulu ukuze kuvalwe. Uma izingxenye zepuleti lensimbi elinombala zigqwalile kakhulu, lezi zingxenye kufanele zishintshwe ngaphambi kokufaka amamojula e-PV.
Isiphetho
Uma ufaka izinhlelo ze-PV, kubalulekile hhayi nje ukucabangela ukuchayeka elangeni kanye nomthunzi kodwa futhi nezici ezifana nomthamo wokuthwala umthwalo, ukudonsa amanzi, kanye nokuvimbela amanzi. Ukuklama kanye nokwenza kahle izinyathelo zokuvimbela amanzi ngesikhathi sokufakwa kuzovimbela izinkinga zesikhathi esizayo, kuqinisekiswe ukuthi uhlelo lwelanga kanye nesakhiwo esifakwe kuso sihlala isikhathi eside.
