Okokuqala, ngokusekelwe kwiinkcukacha kunye neemodeli zeemodyuli ze-PV, inani leemodyuli, kunye noqwalaselo lwe-series array, ubukhulu besakhiwo se-array bunokumiselwa. Okwesibini, ngokwe-latitude yendawo yeprojekthi kunye nomgaqo wokwandisa ukuveliswa kwamandla onyaka kwenkqubo ye-photovoltaic, i-angle efanelekileyo yokuthambeka kunye nesithuba se-arrays sinokumiselwa. Okwesithathu, ngokusekelwe kwizixhobo zomoya kunye nenqanaba eliphezulu lomoya kwindawo yeprojekthi, umthwalo ophezulu womoya oza kuthwalwa yi-array unokumiselwa. Ngokufanelekileyo, isiseko kunye nesakhiwo senkxaso se-array zihlalutywa ukuze kujongwe uxinzelelo kwaye ziyilwe ngokulandela imigaqo yoyilo lwe-mechanical. Ukongeza, xa kuyilwa i-PV array, umda ongezantsi we-array kufuneka ugcine ubude be-30-50 cm ngaphezu komhlaba okanye uphahla ukuthintela ukuphazanyiswa lukhula kunye nokungcwatywa phantsi kwekhephu ngexesha lasebusika.
Isiseko seArray (okanye iSiseko)
Isiseko ngokubanzi sakhiwa ngesamente egalelwe emhlabeni okanye kumaleko wesakhiwo sophahla, kwaye phezu kophahla, kusetyenziswa iifreyimu zegridi (ezineebhloko ze-ballast). Isakhiwo senkxaso ye-array sidla ngokuxhonywa kwisiseko kusetyenziswa ii-flanges kunye nezinto ezifakwe ngaphakathi okanye ngokubhoboza imingxunya kwisiseko sesamente kunye nokufakelwa ngee-bolts zokwandisa. Ukwakha uphahla, isiseko kufuneka sibekwe kwiindawo ezifana neendonga okanye imiqadi yesakhiwo esiphambili njengoko kufuneka kuyilo, ukuqinisekisa ukuqina okuqinileyo kwisakhiwo esiphambili. Kwangaxeshanye, kufuneka kuqatshelwe ukuba iindawo zokufakela ezingachanekanga zesakhiwo senkxaso ye-array kwisiseko zinokubangela ukuphambuka, okuchaphazela uxinzelelo kwisakhiwo esiphambili.
Iimfuneko zoYilo lweSiseko kunye noLwakhiwo lweNkxaso
Xa kuyilwa isiseko se-array kunye nesakhiwo senkxaso, kufuneka kuqwalaselwe ngokupheleleyo izinto ezithwala umthwalo, ukumelana nomoya, kunye nezinto ezibangela inyikima. Kwiindawo ezikunxweme lolwandle, kufuneka kuqwalaselwe ngakumbi ukumelana neenkanyamba, ukuthintela ukufuma, kunye nokumelana nokugqwala kwi-salty spray. Ngaphambi kokufaka isakhiwo senkxaso, kufuneka kufakwe izinto ezithintela ukugqwala, kwaye izinto ezifakwe kwisinyithi eziveziweyo kufuneka zinyangwe ngokuchasene nokugqwala kunye nonyango oluthintela ukugqwala ukuthintela umonakalo kunye nokulahleka kwamandla. Izinto ezifakelwayo ezisetyenziselwa ukudibanisa isakhiwo senkxaso ye-array kufuneka zenziwe ngentsimbi engagqwaliyo. Ukuba kusetyenziswa izinto ezifakelwayo ze-galvanized, kufuneka zihambelane nemigangatho yesizwe ukuqinisekisa ubomi bazo benkonzo kunye nokumelana nokugqwala. Iibholiti, amantongomane, ii-washer ezisicaba, kunye nee-spring washer kufuneka zihlangabezane neemfuno zoyilo lobungakanani, iinkcukacha, kunye neemodeli. Emva kokuqinisa iibholiti, inxalenye eveziweyo kufuneka ibe zizibini kwisithathu ubude bobubanzi bebholiti.
Amanyathelo Athile Esityalo Sombane se-PV Esifakwe Emhlabeni
Ngokweemeko zangempela zesiza:
1. Phawula iindawo kwaye ugrumbe imingxuma yesiseko kwindawo elinganisiweyo.
2. Beka izinto ezifakwe ngaphakathi, beka isikhunta, uze ugalele isamente. Emva kokunyibilika iiyure ezingama-48, faka isakhiwo senkxaso ye-array.
3. Faka iimodyuli ze-PV, cwangcisa iingcingo, misela isiseko somhlaba kunye nokukhusela umbane, uze ubeke imisele yeentambo.
Uvakalelo lweeModyuli zePV kwiDeformation
Kuyaziwa ukuba iimodyuli ze-solar PV, njengezinto ezithwala iglasi, zinobuthathaka kakhulu ekuguqukeni. Oku kungenxa yokuba iglasi yinto ebuthathaka, enokonakala ngokulula kukungahlali kakuhle kwenkxaso kunye nokwanda kobushushu kunye nokucutheka ngaphakathi komgca wemodyuli.
Ngenxa yomahluko kwii-coefficients zokwandisa phakathi kwentsimbi kunye neglasi, xa ubunzima bomda kwinxalenye yeglasi bukhulu, amandla okwandisa angavela phakathi kwenxalenye yeglasi kunye nesakhiwo sentsimbi, nto leyo echaphazela kakubi iglasi. Ke ngoko, ukusebenzisa amacandelo aqinileyo aqinileyo njengesakhiwo sokuxhasa iimodyuli zePV kuyawoyisa imiphumo emibi yokuqina kwezakhiwo zentsimbi. Oku kunceda ekunciphiseni ukuguquguquka kwesakhiwo, ukuhlala kwesiseko, kunye nokuguquguquka kokwandiswa, okwenza kube sisakhiwo esifanelekileyo sokuxhasa iimodyuli ze-PV zelanga. Ukuphucula uyilo lwesakhiwo senkxaso kunye nesiseko akupheleli nje ekufezekiseni iimfuno zokufakelwa kunye nokusebenza kweemodyuli kodwa kunciphisa kakhulu utyalo-mali kwizibonelelo kunye neziseko.
