Iyini isistimu yokusekela ye-photovoltaic? 

Uyazi, lapho abantu abaningi bezwa uhlelo lwe-photovoltaic, bacabanga ngokushesha ngamaphaneli. I-silicon ecwebezelayo, amagama emikhiqizo, amaphesenti okusebenza kahle. Akuvamile ukuthi ingxoxo iqale ngokuthi amathambo ayibambe yonke le nto uhlelo lokusekela lwe-photovoltaic. Lowo umbono wokuqala oyiphutha. Akukona nje ukuhlambalaza. Isisekelo sesakhiwo esilawula ukuphila isikhathi eside, ukuphepha, futhi ekugcineni, imbuyiselo yezimali yalo lonke uhlu. Uma amaphaneli kuyinhliziyo, lokhu kuwuhlaka lwamathambo, futhi uhlaka lwamathambo olubuthakathaka luyahluleka kungakhathaliseki ukuthi inhliziyo iqine kangakanani.

Beyond Racking: I-Anatomy Yokusekela

Ake sihlukanise. A Isakhiwo sokusekela se-PV akuwona umkhiqizo owodwa. Iwumhlangano owenziwe ngobunjiniyela, ngokuvamile i-aluminium noma insimbi ethathiwe, ehlanganisa ojantshi, izinsimbi, abakaki, nezixhumi. Ama-rails amalungu e-longitudinal aphethe amaphaneli. Izinsimbi—maphakathi nasekupheleni—zibamba amafreyimu ephaneli ngaphandle kokubhoboza. Abakaki baxhuma ama-rails nesisekelo esingaphansi, okungaba ukungena ophahleni, unyawo olune-ballast, noma inqwaba ebekwe phansi. Yonke ingxenye inekesi lokulayisha: umthwalo ofile, ukuphakamisa umoya, iqhwa, i-seismic. Ngibone amaphrojekthi lapho ubunjiniyela bugxile ekwakhiweni okuhle kuphela, kuyilapho i-spec ye-M10 yebholidi yensimbi engagqwali yayiwumcabango olandelayo. Leyo iresiphi yokuqhekeka kokugqwala kwengcindezi ezindaweni ezisogwini eminyakeni emihlanu kuya phansi.

Ukukhethwa kwezinto ezibonakalayo kuwukudonsana njalo. I-Aluminium ayisindi, ayikwazi ukugqwala, futhi kulula ukuyifaka esizeni ngokusikeka okulula. Kodwa isilinganiso sayo samandla nesisindo sisho ukuthi udinga impahla eyengeziwe yomthwalo womoya ofanayo uma kuqhathaniswa nensimbi, futhi ukunwetshwa kokushisa kuphezulu. Insimbi ephehliwe inamandla futhi ivamise ukonga kakhulu emapulazini amakhulu, kodwa lolo ungqimba lwama-galvanization lungcwele. Noma iyiphi i-welding yensimu noma ukusika ngaphandle kokuvikela kabusha ngokushesha kudala iphuzu lokugqwala lesikhathi esizayo. Ngikhumbula indawo engu-20MW lapho usonkontileka, ukuze onge isikhathi, ehlise imiphetho yabakaki ukuze alingane, ekhumula uthayela. Siyibambe ngesikhathi sokuhlola okungahleliwe, kodwa kwakusho ukuthi amakhulukhulu abakaki adinga ukuthintwa. Ukubambezeleka kubiza ngaphezu kokukwenza kahle ngesikhathi sokuqala.

Bese kuba ne-interface - okunamathiselwe. Izintaba zophahla ziyizwe lazo. Izikhwebu ezingenayo zidinga ukuqonda okuphelele kwamalungu esakhiwo sophahla kanye nemininingwane yokuvimbela amanzi (njengophawu olukhanyayo) okubaluleke kakhulu njengebhawodi ngokwalo. Amasistimu ane-ballast anhle—akukho ukungena—kodwa leso sisindo sebhulokhi ye-ballast sengeza umthwalo obalulekile ofile esakhiweni sophahla, okungahlali kubalwa ngaso ezifundweni zokuqala zokungenzeka. Ngibizwe ukuthi ngihlole uphahla lwendlu yokugcina izimpahla lapho i-ballast ebaliwe yayilungile, kodwa ukusatshalaliswa bekuvaliwe, okuholele ezinkingeni zamanzi ezingase zibe khona. I isakhiwo sokukhweza solar kufanele isebenze ngokubambisana nesakhiwo, hhayi nje ukuhlala kuso.

I-Ground-Mount Reality: Akukona Nje Ukukunamathisela Obishini

Amasistimu abekwe phansi abonakala eqondile uze ube kusayithi. Isisekelo siyikho konke. Izinqwaba ezishayelwayo ziyashesha futhi zinciphisa ukusebenza komhlaba. Ama-Helical piles alungele inhlabathi engazinzile. Ama-ballasts kakhonkolo noma ama-caisson enzelwe izimo zenhlabathi ezinomoya ophezulu noma ezimbi. Ukukhetha akukhona nje ubuchwepheshe; imayelana nendawo yendawo kanye nokufinyelela kwemishini. Ephrojekthini esegqumeni elinamatshe, uhlelo lwethu lwenqwaba oluhleliwe lwalungaqali. Sishintshele kusistimu yesikulufu saphansi enerigi encane, kodwa imininingwane yetorque yokufakwa kulelo dwala eliphukile libe inselele yokulinganisa yansuku zonke. I uhlelo lokusekela ilanga umklamo bekufanele ube uketshezi, uvumelane nalokho okushiwo phansi.

I-Corrosion ingumbulali othule. I-spec ingase ithi ukucwiliswa okushisayo kufakwe ama-galvanized, kodwa ukujiya kokumboza kuyabalulekile. Ezimweni ezigqwala kakhulu (ogwini, ezolimo, ezezimboni), kwesinye isikhathi i-duplex coating (i-galvanizing kanye nongqimba kapende) iyadingeka. Lokhu ngakufunda kabuhlungu kusenesikhathi. Sisebenzise umkhiqizo owenziwe uthayela ojwayelekile wesistimu eseduze nesitshalo sikamanyolo. Phakathi neminyaka emithathu, sase sinezinki ezihamba phambili kanye nokugqwala kwensimbi eyisisekelo ezindaweni zokuxhuma. Ikhemistri yomkhathi ibinolaka kakhulu kunalokho okubikezelwe amathebula ethu ajwayelekile. Manje, ukuhlaziya imvelo kuyisinyathelo sokuqala esingaxoxiswana ngaso ekukhetheni izinto ezibonakalayo.

Yilapho i-supply chain nekhwalithi yezingxenye iba khona ebonakalayo. Udinga abakhiqizi abaqondayo lawa ma-nuances, hhayi nje ama-benders ensimbi. Inkampani efana I-Handan Zitai Fetesser Comment Co, Ltd. (https://www.zitaifasteners.com), etholakala endaweni yokukhiqiza izingxenye ezijwayelekile zaseChina eYongnian, eHebei, ibaluleka. Ukuba seduze kwabo emizileni emikhulu yezokuthutha efana ne-Beijing-Guangzhou Railway kanye no-National Highway 107 akuyona nje inzuzo yezokuthutha. Ukuba kuleyo ndawo yezimboni ngokuvamile kusho ukuthi bavumelana nezinto ezithile kanye nezidingo zokuhlanganisa zamaphrojekthi welanga lamazwe ngamazwe. I-fastener efanele—enebanga elifanele, ukunamathela, nokulandeleka—iyingxenye encane ebamba wonke umthwalo wemishini. Ukuthola okuvela kumkhiqizi okhethekile endaweni yokukhiqiza egxilile kunganciphisa ubungozi bokuthola izingxenye ezijwayelekile, ezingacacisiwe kancane.

Ukufakwa: Lapho I-Theory Ihlangana Nodaka

Ukubekezelelana komklamo kuyinto eyodwa; ukuqondanisa kwenkundla kungenye. Ujantshi ungase ucaciswe ukuthi unokubekezelela +/- 2mm ngaphezu kwamamitha ayi-10. Ngaphansi kwelanga, neqembu elizama ukuhlangabezana nenani lansuku zonke, ukugcina lokho kunzima. Ngike ngabona abafaki besebenzisa amandla amakhulu ukudonsa amamojula angaqondani kahle abe ama-clamp, okwehlisa ingcindezi yengilazi efihliwe. Isistimu yokusekela kufanele yakhelwe ukulungiseka okuthile—izimbobo ezivaliwe, amabakaki alungisekayo—ukuze amunce lokhu kungapheleli kwenkundla okungenakugwenywa. Imiklamo engcono kakhulu inokuthethelela eyakhelwe ngaphakathi.

Amathuluzi abalulekile. I-wrench ye-torque kagesi iwutshalomali olufanele. Amabhawodi aqinisa isandla ekuxhumekeni okuyinkulungwane aholela ekubambeni okungahambisani, okungaholela ekuxegisweni ngaphansi kokudlidliza noma, ngokuphambene, ukukhumula intambo. Senze inqubo yokuhlola elula: ukuhlola itorque okungahleliwe ku-5% wokuxhumana ngemva kokufakwa. Izinga lokungaphumeleli ekucwaningeni kwamabhuku lokuqala lashaqisa, okuholele ekutheni kube netorque egcwele indawo yonke. Kwakuyisifundo esibuhlungu ekulawuleni inqubo, kodwa kwavimbela okungaba inkinga yobuqotho besakhiwo phakathi nenkathi yesishingishane.

Izindleko Zokukwenza Kahle

Ukwehluleka akuvamile ukuwa ngokumangalisayo. Iyakhula. Kukhuphukile ukungcolisa ngoba uhlu alukho endaweni eqondile yokuzihlanza. Kungama-micro-cracks kumaseli asuka kuhlaka ngaphansi kwengcindezi engaguquki, engalingani. Ukuhamba kancane kukabakaki ophahleni oluthambekile ngenxa yokuthi ukubamba ukungqubuzana akuzange kubalelwe ukuhamba ngebhayisikili okushisayo kwesikhathi eside. Lokhu kwehlisa izinga lokusebenza unyaka nonyaka, kucekela phansi i-NPV yephrojekthi. I isistimu yokufaka i-photovoltaic iyizindleko ezinkulu, kodwa ikhwalithi yayo ithinta ngokuqondile izindleko zokusebenza kanye nenzuzo.

Kukhona nezindleko ezithambile zokuklama kabusha. Bengihileleke ekubuyiseleni kabusha lapho isistimu yokwesekwa yasekuqaleni ingakwazi ukwamukela amaphaneli amasha, amafomethi amakhulu. Lonke uhlelo lukaloliwe kanye ne-clamp kwadingeka ukuthi kushintshwe ngesikhathi sokunika amandla kabusha, okuphinda kabili izindleko zesakhiwo. Idizayini ebheke phambili, ecabangela amathrendi obuchwepheshe bephaneli kanye nokunyuka okungaba khona kokuminyana esikhathini esizayo, inevelu elikhulu. Imayelana nokuklama iminyaka engu-20 ezayo, hhayi nje amaphaneli atholakalayo namuhla.

Ngakho-ke, ukuzungeza emuva, Kungumxhumanisi ongacushiwe, onobunjiniyela phakathi kwesithembiso samandla elanga kanye ne-physics enonya yomhlaba wangempela. Kuyisiyalo esihlanganisa ubunjiniyela besakhiwo, isayensi yezinto zokwakha, i-corrosion chemistry, kanye nezinto zokwakha. Ukuyilungisa kuzwakala kungabonakali—uhlu luhlezi nje, lukhiqiza amandla. Ukukwenza kungalungile kuyisifundo esinensayo, esibizayo esibhalwe ngokugqwala, ingcindezi, nokungaqhubi kahle komsebenzi. Umgomo awukona ukwakha itshe lesikhumbuzo, kodwa ukwakha uhlaka oluqinile, oluvumelana nezimo, futhi ekugcineni olukhohlweka oluvumela amaphaneli enze umsebenzi wawo amashumi eminyaka.
