I-2017 yaziwa ngokuba ngunyaka wokuqala we-PHOTOVOLTAIC esasazwayo yaseTshayina, ukwanda konyaka kwe-PV efakwe kwi-PV esasazwayo iphantse ibe yi-20GW, kuqikelelwa ukuba i-PV esasazwa yindlu iye yanda ngamakhaya angaphezu kwama-500,000, apho iZhejiang, iShandong amaphondo amabini Ufakelo lwe-PV lwendlu lungaphezulu kwe-100,000 yamakhaya.
Njengoko kwaziwa kubo bonke, xa kuthelekiswa nesikhululo samandla esikhulu emhlabeni, okusingqongileyo kophahla olusasazwe kwisikhululo samandla se-photovoltaic sinzima ngakumbi, ukuze kuthintelwe impembelelo yezithintelo ezifana ne-parapet, izakhiwo ezijikelezileyo, iintambo ezingaphezulu, itshimini yophahla, ilanga. Isifudumezi-manzi, kunye nokuthintela ingxaki yokwahluka malunga nokukhanya kwemini eluphahleni akuhambelani, indawo ekhoyo yofakelo lophahla iya kuncitshiswa kwaye nomthamo ofakelweyo uya kucuthwa.
Ukuba le ndawo yokukhusela ayiphetshwa, isikhululo samandla siya kubangela uthotho kunye nokungahambelani okunxuseneyo ngenxa yokhuselo okanye ukukhanya okungaguqukiyo, kunye nokusebenza kakuhle kokuveliswa kombane kwesisikhululo samandla kuya kuncitshiswa.Ngokweengxelo zophando ezifanelekileyo, umthunzi wendawo we-shadow shading yeemodyuli ze-photovoltaic uya kunciphisa uchungechunge lonke lokuvelisa amandla ngaphezu kwe-30%.
Ngokutsho kohlalutyo lwe-PVsyst yokulinganisa imodeli, ngenxa yeempawu zechungechunge lwe-photovoltaic, ukuba ukuveliswa kwamandla kwimodyuli enye ye-photovoltaic kuncitshiswe ngama-30%, ukuveliswa kwamandla kwamanye amacandelo kwiqela lonke kuya kuwela kwinqanaba eliphantsi elifanayo, eliya kuwela kwinqanaba elifanayo. yimpembelelo emfutshane yebhodi yombhobho wokhuni kwinkqubo yeqela le-photovoltaic.
Ngenxa yale meko ingentla, kucetyiswa ukuba ufake i-PV optimizer yamandla, engakwazi ukulawula ngokuzimeleyo ukunyuka koxinzelelo kunye nokuwa kwemodyuli nganye ye-PV, ukuxazulula iingxaki zechungechunge kunye nokungahambi kakuhle kwamaqela e-photovoltaic okubangelwa ukuqhekeka okufihliweyo, iindawo ezishushu, ukuvalwa kwesithunzi, ukucoceka okwahlukileyo, ukuqhelaniswa nokungahambelani kunye nokukhanya, kwaye kunokuphucula ukuveliswa kwamandla ngokubanzi kwenkqubo.
Amatyala amathathu asetyenziselwa ukuvavanya ukusebenza kwe-photovoltaic power optimizer.
Isikhululo samandla esiphezu kophahla lwe-8KW, umthamo wokuvelisa indawo ephuculweyo yonyuke nge-130%, yenze i-6 KWH yombane eyongezelelweyo yonke imihla.
Isikhululo samandla sasekhaya esiyi-8KW sakhiwe kumgangatho wesithathu wesakhiwo sokuhlala.Amanye amacandelo afakwe kwi-balcony canopy kwaye amanye amacandelo afakwe kwi-tile surface.
Imodyuli yebhetri ifakwe kwi-heater yamanzi kunye nenqaba yamanzi esecaleni, efaniswe yi-PVsyst kwiinyanga ezili-12 zonyaka.Ngenxa yoko, ivelisa umbane ongaphantsi kwama-63% kunokuba ifanele, i-8.3 KWH kuphela ngosuku,
Emva kokuba i-optimizer ifakwe kolu chungechunge, ngokuthelekisa ukuveliswa kwamandla kwiintsuku ezili-10 zelanga ngaphambi nangemva kokufakela, uhlalutyo lulandelayo:
Usuku lokuqala lokusebenza kwe-optimizer yayinguDisemba 20, kwangaxeshanye, inxalenye engwevu yokuvelisa amandla eqela lothelekiso yongezwa ukuze kuhlalutywe ukuba ingabandakanyi impembelelo yemitha, ubushushu kunye nezinye iziphazamiso.Emva kofakelo lwe-optimizer, umlinganiselo wokunyuka kwamandla yi-130%, kwaye umyinge wokunyuka kwamandla wemihla ngemihla yi-6 KWH.
Isikhululo samandla esiphezu kophahla lwe-5.5KW, ukuveliswa kwamandla eqela eliphuculweyo kunyuke nge-39.13%, kwenze i-6.47 KWH yombane eyongezelelweyo yonke imihla.
Kwisikhululo samandla esiphezu kophahla lwe-5.5kW esisebenza ngo-2017, zombini iintambo zichatshazelwa yikhusi yemithi ejikelezileyo, kwaye ukuveliswa kwamandla kuphantsi kunomgangatho oqhelekileyo.
Ngokweyona meko yokukhusela kwisayithi, imodeli kunye nohlalutyo lwenziwa kwi-pvsyst.Ezi ntambo zimbini zineemodyuli ze-photovoltaic ze-20, eziza kuthungwa kwiinyanga ezili-10 zonyaka, zinciphisa kakhulu ukuveliswa kwamandla kwenkqubo.Ukushwankathela, i-photovoltaic power optimizer ifakwe kwiimodyuli ezimbini zeemodyuli ze-20 kwindawo yeprojekthi.
Emva kwe-20 ye-photovoltaic optimizers yamandla efakwe kwiintambo ezimbini, ngokuthelekisa ukuveliswa kwamandla kwiintsuku ezi-5 zelanga ngaphambi nasemva kofakelo, uhlalutyo lulandelayo:
Usuku lokuqala lokusebenza kwe-optimizer yayinguDisemba 30, kwangaxeshanye, inxalenye engwevu yokuvelisa amandla eqela lothelekiso yongezwa ukuze kuhlalutywe ukuba ingabandakanyi impembelelo yemitha, ubushushu kunye nezinye iziphazamiso.Emva kofakelo lwe-optimizer, umlinganiselo wokunyuka kokuveliswa kwamandla yi-39.13%, kwaye umyinge wokunyuka kwamandla kwimihla ngemihla yi-6.47 KWH.
Isikhululo samandla esisembindini we-2MW, ukuveliswa kwamandla kwamaqela amane kwindawo yokuphucula kunyuswe nge-105.93%, kwenziwe umbane othe chatha wama-29.28 KWH yonke imihla.
Kwisikhululo samandla sentaba esisembindini we-2MW esithe saqalisa ukusebenza ngo-2015, indawo yokukhusela ithunzi ekwisiza inzima kakhulu, eyahlulahlulwe kakhulu yangamacandelo amathathu: ukhuseleko lwepali yombane, ukukhuselwa kwemithi kunye nezithuba ezincinci zangaphambili nangasemva zamacandelo.Umphambili kunye nomqolo okhuselayo wamacandelo uya kuvela ebusika kuba i-engile yobude belanga iba sezantsi, kodwa hayi ehlotyeni.Ukufihlwa kwepali kunye nokufihlwa kwemithi kwenzeka unyaka wonke.
Imodeli yenkqubo yonke isekwe kwi-pvsyst ngokwemodeli yeeparamitha zamacandelo kunye ne-inverters kwinkqubo, indawo yeprojekthi kunye nemeko ethile yokuba i-shaded.Kwiintsuku ezinelanga, ukulahleka kwemitha yokukhanya yi-8.9%.Ixabiso lethiyori alinakufunyanwa ngenxa yelahleko yokuveliswa kwamandla ngendlela engafanelekanga okubangelwa kukungangqinelani.
Ngokweemeko zesayithi, iintambo ezine zikhethiweyo, i-22 photovoltaic power optimizers ifakwe kumtya ngamnye, kwaye i-88 iyonke i-optimizers ifakwe.Ngokuthelekisa ukuveliswa kombane phambi nasemva kofakelo kunye nokuveliswa kwamandla eentambo ezikufuphi ezingafakelwanga ze-optimizer, uhlalutyo lulolu hlobo lulandelayo:
Kwiintsuku ezinelanga, ukuphazamiseka kokukhanya kwemozulu kufuneka kuncitshiswe, kwaye inxalenye engwevu yokuvelisa amandla oluhlu lweqela lothelekiso kufuneka longezwe ukuhlalutya ukuphelisa impembelelo yesixa semitha, ubushushu kunye nolunye uphazamiseko.Emva kokuba i-optimizer ifakiwe, ukuveliswa kwamandla kwisikhululo samandla yi-105.93% ephezulu kunelo xesha lingafakwanga, umyinge wokuvelisa umbane ngentambo nganye ngosuku unyuswe nge-7.32 KWH, kunye nokuveliswa kwamandla eentambo ezine. inyuke nge-29.28 KWH ngosuku.
Ngenxa yokunciphisa izikhululo zamandla amakhulu kunye nobunzima bemithombo kunye nokusingqongileyo njengeentaba, kucetyiswa ukuba abantu abaninzi basebenzise indawo yophahla ukufakwa kwenkqubo ye-photovoltaic.Siya kubonelela ngeskimu sokufakela inkqubo epheleleyo kunye neskimu sokucoca iiphaneli zelanga ezilandelayo.Siya kuhlala sizibophelele ekuboneleleni abasebenzisi amandla akhuselekileyo, azinzileyo kwaye athembekileyo e-photovoltaic.
