Amanani kagesi ayenyuka, futhi abanikazi befekthri abaningi babheka uphahla lwabo olungasetshenzisiwe njengezindawo ezingase zibe khona ze-solar PV.
Yini okufanele ize kuqala? Abanikazi abaningi baqala ngokubuza izinkampani zelanga ngamanani wemojula. Lokho kuyingxenye yesithombe kuphela. Ngesakhiwo sefekthri esenziwe ngensimbi esikhona, isinyathelo sokuqala ukuhlola kwesakhiwo. Uma uphahla lungakwazi ukusekela ngokuphepha uhlelo, umnotho wephrojekthi awuhlanganisi.
Esinye isilinganiso somkhakha sibeka izinga lokuphasa lokuhlola umthamo we-PV ophahleni lwensimbi olukhona ngaphansi kuka-50%. Cishe ingxenye yezakhiwo zefekthri ezindala ingase idinge ukuqiniswa ngaphambi kokuba kufakwe ilanga. Ukweqa ukuhlola nokuya ngqo ekufakweni kungaholela ekulimaleni kwe-purlin, ukuvuza kophahla, noma ngisho nezehlakalo zokuphepha kwesakhiwo.
Lo mhlahlandlela uchaza amasheke amathathu, indlela yokuphasa/yokwehluleka, kanye nezindleko ezikhombisayo uma uphahla lungaphumeleli ukuhlolwa.
Hlola 1: Ikhono Lokuthwala
Okufanele Uhlole
Hlola ukuthi umklamo wangempela unawo yini umthamo owanele womthwalo obekiwe. Isistimu ye-PV ephezu kophahla (amamojula, isakhiwo sokukhweza nezintambo), efakwe ngokuhambisana nomthambeka wophahla, yengeza cishe 15–26 kg/m² (0.15–0.26 kN/m²).
Lokho kungase kungezwakali njengokuningi, kodwa kuyi- umthwalo ofile unomphela. Umklamo wangempela uvame ukuthatha umthwalo obukhoma ongu-0.5 kN/m² kuphela ophahleni olungahloselwe ukufinyelela okuvamile. Uma umthwalo ofile we-PV usuhlanganiswe nemithwalo yomoya neqhwa, ungasebenzisa kalula umthamo osele.
Imibandela yokudlula/yehluleka
| Into yokuhlola | Dlula | Yehlulekile |
| Isilinganiso sokucindezeleka ngaphansi kwamakesi ahlanganisiwe ofile, aphilayo, komoya kanye neqhwa | Ngaphakathi komkhawulo ovunyelwe | Yeqa umkhawulo |
| Ukuchezuka kozimele oyinhloko | ≤ L/250 (umkhuba womkhakha ojwayelekile) | Yeqa umkhawulo |
| Ukususwa kwekholomu phezulu | Ngaphakathi kwekhodi yomkhawulo | Yeqa umkhawulo |
Uma uphahla luhluleka: Qinisekisa uhlaka oluyinhloko, isibonelo ngokwandisa osayizi bamalungu noma ukwengeza ukuhlanganisa. Lesi isilinganiso esibizayo sokuqinisa futhi sidinga idizayini yobunjiniyela eqondene nephrojekthi.
Hlola i-2: I-Purlin Span kanye nosayizi wesigaba
Okufanele Uhlole
I-PV mounting clamp igxilwe kuma-purlins. Ngenxa yokuthi ama-purlin ekuqaleni ayenosayizi wemithwalo ekhona, i-15–26 kg/m² eyengeziwe ingase iwaphuqe ngaphezu komthamo wawo ovunyelwe. Emabhilidini efekthri ye-portal-frame ane-purlins yesigaba esingu-C- noma esingu-Z, le mithetho emibili yesithupha ingasetshenziselwa ukuhlola kokuqala:
- Ubude be-Purlin bucishe bube ngu-6 m enegama lesigaba elingaphansi kuka-180 → okungenzeka lweqe umkhawulo ovunyelwe
- I-Purlin span ecishe ibe ngu-8 m enegama lesigaba elingaphansi kuka-220 → okungenzeka idlule imikhawulo evumelekile
Imibandela yokudlula/yehluleka
| Into yokuhlola | Dlula | Yehlulekile |
| Isilinganiso sokucindezeleka kwe-Purlin | Ngaphakathi komkhawulo ovunyelwe | Yeqa umkhawulo |
| Ukuphambuka kwe-Purlin | ≤ L/150 | Yeqa umkhawulo |
| Ukuhlelwa kwebhuloho/thayi (uma i-span> 6 m) | Okungenani imigqa emi-2 | Umugqa owodwa kuphela; ingozi yokungaqini kahle kwezinhlangothi |
Uma ama-purlins enganele kodwa uhlaka oluyinhloko lunomthamo owanele, ukuqinisa noma ukufaka esikhundleni kuphela ama-purlins kuyinketho elawulekayo futhi ngokuvamile kubiza kancane ezinyathelweni ezintathu zokuqinisa.
Hlola 3: Isimo Sokugqwala
Okufanele Uhlole
Hlola i-coating yokuvikela nokulahlekelwa okuhlobene nokugqwala kwendawo ephambanayo. Naka kakhulu izindawo lapho uthuli noma amanzi kunqwabelana khona, izindawo ezingaphansi kokumanziswa ngokuphindaphindiwe nokomisa, ukuxhuma nezindawo ezicashile, kanye nemiphetho yezikhala zophahla.
Indlela: Okokuqala hlola ukunameka komonakalo. Ezindaweni ezilimele, sebenzisa i-ultrasonic gauge ukujiya noma ama-caliper ukuze ulinganise ubukhulu bezinto ezibonakalayo bese uqhathanisa nobukhulu besigaba sokuqala.
Imibandela yokudlula/yehluleka
| Into yokuhlola | Dlula | Yehlulekile |
| I-Protective coating | Iqinile noma iyalungiseka | Ukuhluleka kokunamathela okusabalele |
| Ukulahleka kwezingxenye eziphambanayo ngenxa yokugqwala | ≤ 5% | > 5% |
| Izixhumanisi (ama-welds/amabhawodi) | Akukho ukuxega noma imifantu | Ama-fasteners avulekile noma ama-weld aphukile |
Uma ukulahlekelwa kwesigaba esiphambanayo ngenxa yokugqwala kudlula u-5%, sebenzisa ukuvikela ukugqwala futhi uqinise ingxenye ethintekile ngaphambi kokuhlola kabusha umthamo wophahla wemithwalo ye-PV. Izinkinga zokuxhuma zihamba phambili ngaphezu kwakho konke okunye: lungisa izixhumi ngaphambi kokucabangela ukufakwa kwelanga.
Uma Uphahla Luhluleka: Lapho Imali Iya Khona
Ububanzi bezindleko zomkhakha oyizinkomba:
| Umsebenzi wokulungisa | Izindleko ezikhombisayo | Amanothi |
| Izibalo zokuqinisekiswa kwesakhiwo | US$1,400–4,200 | Kudingeka; hlanganyela nefemu yobunjiniyela bezakhiwo efanelekayo noma inkampani yesakhiwo sensimbi ukuze imodeli yesakhiwo kanye nokuqinisekisa |
| Ukuqinisa / ukushintshwa kwe-Purlin | US$2,800–7,000 | Isigaba esivame kakhulu sokuqinisa |
| Ukuqiniswa kohlaka oluyinhloko | US$11,000–21,000 | Khulisa osayizi bamalungu/engeza amabhrakhi; idizayini ethize yephrojekthi iyadingeka |
| Ukuqiniswa kwesisekelo | US$14,000–28,000 | Inketho ebanzi kakhulu; okokuqala qinisekisa ukuthi kudingekile ngempela |
Isexwayiso: Imboni eyodwa ifake i-PV ngaphandle kokwenza izibalo zesakhiwo kuqala. Ngemva konyaka, ama-purlins ayo asehle ngo-5 cm. Ukulungisa nokuqinisa kubiza cishe u-US$25,000, futhi ukukhiqizwa kwamiswa inyanga yonke.
Ukuhlola uphahla kubiza izinkulungwane ezimbalwa zamaRandi kuphela. Ukuyeqa kusho ukubeka uphahla olubiza amakhulu ezinkulungwane zamaRandi—kanye nawo wonke umugqa wokukhiqiza—engozini.
Ngemva Kokuhlola: Icala Lomklamo Odidiyelwe
Uma uphahla seluphumelele ukuhlolwa, cabanga ukuhlanganisa i-PV ekwakhiweni kwesakhiwo kunokusebenzisa i-PV (BAPV) evamile esetshenziswa isakhiwo.
- Amamojula e-PV angangena esikhundleni sengxenye yophahla olwengeziwe edizayini ye-PV (BIPV) ehlanganiswe nesakhiwo, okungenzeka yehlise kunokwenyusa umthwalo unomphela.
- Hlela ukukhweza kanye nemininingwane yokuxhuma emidwebeni kusukela ekuqaleni ukuze ugweme ukulungiswa kwesayithi.
- Ophahleni olude olunomthamo olinganiselwe wokulayisha, i-BIPV ingase iqede noma yehlise kakhulu izindleko zokuyiqinisa.
Ngesakhiwo esisha sefekthri, lokhu kusho “umklamo owodwa wesakhiwo, isigaba esisodwa sokwakha, kanye nokukhiqizwa kukagesi okwakhelwe phakathi.” Embonini ekhona edlula ukuhlolwa, i-retrofit evamile ihlala iyinketho esebenzayo—kodwa imininingwane yokuxhuma nokusabalalisa umthwalo kufanele kusingathwe ithimba lokuklama elinolwazi lwesakhiwo sensimbi.
Imibuzo Evame Ukubuzwa
Q1: Ingabe ukuqinisekiswa kwesakhiwo kuyadingeka ngaphambi kokufaka i-solar ophahleni?
Yebo. Izilinganiso zemboni zibeka izinga lokuphasa kokuhlolwa kwe-PV ophahleni lwensimbi olukhona ngaphansi kuka-50%. Izibalo zesakhiwo zisiza ukulawula le ngozi; ngama-US$1,400–4,200, angenye yezindlela zokuvikela ezibiza kancane kuphrojekthi.
Q2: Ingabe isakhiwo sefekthri esineminyaka engu-20 sisengakwazi ukusekela i-solar?
Iminyaka yobudala iyodwa ayinqumi. Isakhiwo esidala singase sidlule uma ukugqwala kulawulwa futhi umklamo wangempela unomthamo owanele ogciniwe. Uma ukulahlekelwa kwesigaba esihlobene nokugqwala kweqa umkhawulo ovunyelwe, sebenzisa ukuvikela ukugqwala futhi ukuqinise kuqala.
Q3: Ubani okufanele alungise umbiko wokuhlolwa kwesakhiwo?
Inkampani yobunjiniyela besakhiwo eqeqeshiwe noma inkampani yesakhiwo sensimbi kufanele ikhiphe umbiko. Kufanele ibhale inhlanganisela yomthwalo, izilinganiso zokucindezeleka, okutholwe ngokuphambuka, nanoma yiziphi izincomo zokuqinisa.
I-Q4: Yisiphi i-purlin span kanye nosayizi wesigaba ngokuvamile ofanelekile ku-solar ophahleni?
Njengomthetho wokuqala wesithupha, ama-purlins esigaba se-C-noma u-Z anegama lesigaba okungenani elingu-180 endaweni engaba ngu-6 m, noma angu-220 cishe ngamamitha angu-8, maningi amathuba okuthi adlule ngaphansi kwemithwalo ye-PV. Ukufaneleka kokugcina kufanele kuqinisekiswe ngezibalo zesakhiwo.
Awuqinisekile ukuthi uphahla lwakho lungasekela i-solar? Thumela ubude, usayizi we-purlin, unyaka wokwakha, nezithombe zophahla ukuze uthole ukuhlolwa kokuqala kwamahhala. I-imeyili: info@xzbesta.com
