I-2017 yaziwa njengonyaka wokuqala we-PHOTOVOLTAIC esakaziwe yaseChina, ukwanda kwaminyaka yonke komthamo ofakiwe we-PV cishe ku-20GW, kulinganiselwa ukuthi i-PV esatshalaliswa yasendlini inyuke ngemizi engaphezu kuka-500,000, lapho iZhejiang, iShandong izifundazwe ezimbili ukufakwa kwe-PV yasendlini kunemizi engaphezu kuka-100,000.
Njengoba kwaziwa yibo bonke, uma kuqhathaniswa nesiteshi esikhulu samandla esiphansi, indawo yesiteshi samandla e-photovoltaic esatshalaliswa ophahleni iyinkimbinkimbi kakhulu, ukuze kugwenywe ithonya lezithiyo ezifana nothango, izakhiwo ezizungezile, izintambo ezingaphezulu, ushimula ophahleni, ilanga. I-heater yamanzi, futhi ukuze kugwenywe inkinga yokwehluka kokukhanya kwelanga ophahleni akuhambisani, indawo etholakalayo yokufaka uphahla izoncishiswa futhi umthamo ofakiwe uzonqunyelwa.
Uma le ngxenye yokuvikela ingagwenywa, isiteshi sikagesi sizobangela ukungafani kochungechunge nokuhambisana ngenxa yesivikelo noma ukukhanya okungaguquki, futhi konke ukusebenza kahle kokuphehlwa kwamandla kwesiteshi kuzoncishiswa.Ngokusho kwemibiko yocwaningo efanele, umthunzi wendawo wamamojula we-photovoltaic uzokwehlisa lonke uchungechunge lokukhiqiza amandla ngaphezu kuka-30%.
Ngokusho kokuhlaziywa kwemodeli ye-PVsyst, ngenxa yezimpawu zochungechunge lwe-photovoltaic, uma ukukhiqizwa kwamandla kwemodyuli eyodwa ye-photovoltaic kuncishiswa ngo-30%, ukukhiqizwa kwamandla kwezinye izingxenye zeqembu lonke kuzowela ezingeni elifanayo eliphansi, okuyinto umphumela omfushane webhodi lombhobho wokhuni ohlelweni lochungechunge lweqembu le-photovoltaic.
Ngenxa yalesi simo esingenhla, kunconywa ukuthi ufake i-PV power optimizer, engakwazi ukulawula ngokuzimela ukuphakama nokuwa kwe-module ngayinye ye-PV, ixazulule izinkinga zochungechunge nokungahambisani okufanayo kwamaqembu e-photovoltaic okubangelwa imifantu efihliwe, izindawo ezishisayo, ukuvaleka kwesithunzi, ukuhlanzeka okuhlukile, ukuqondiswa okungahambisani nokukhanya, futhi kungathuthukisa ukukhiqizwa kwamandla jikelele kwesistimu.
Kusetshenziswe amacala amathathu ukuhlola ukusebenza kwe-photovoltaic power optimizer.
Isiteshi sikagesi esisophahleni esingu-8KW, amandla aphehlayo wendawo ethuthukisiwe anyuke ngo-130%, akhiqize ugesi ongu-6 KWH owengeziwe nsuku zonke.
Isiteshi sikagesi sasendlini esingu-8KW sakhiwe esitezi sesithathu sebhilidi lokuhlala.Ezinye izingxenye zifakwe ku-balcony canopy futhi ezinye izingxenye zifakwe endaweni ye-tile.
Imojula yebhethri ifakwe umthunzi yi-heater yamanzi kanye nombhoshongo wamanzi oseduze, olingiswa yi-PVsyst izinyanga ezingu-12 zonyaka.Ngenxa yalokho, ikhiqiza ugesi ongaphansi ngo-63% kunalokho obekufanele, u-8.3 KWH kuphela ngosuku,
Ngemuva kokuthi isilungiseleli sesifakiwe kulolu chungechunge, ngokuqhathanisa ukukhiqizwa kwamandla ezinsukwini eziyi-10 libalele ngaphambi nangemuva kokufakwa, ukuhlaziya kungokulandelayo:
Usuku lokuqala lokusebenza kwe-optimizer kwakungu-December 20, ngesikhathi esifanayo, ingxenye empunga yokukhiqiza amandla eqembu lokuqhathanisa yengezwa ukuze kuhlaziywe ukuze kukhishwe ithonya lemisebe, izinga lokushisa nokunye ukuphazamiseka.Ngemva kokufakwa kwe-optimizer, isilinganiso sokwanda kokukhiqizwa kwamandla singu-130%, futhi isilinganiso sokunyuka kwamandla nsuku zonke si-6 KWH.
Isiteshi samandla ophahleni esingu-5.5KW, ukukhiqizwa kukagesi kweqoqo elenziwe kahle kukhuphuke ngo-39.13%, kukhiqize ugesi ongu-6.47 KWH owengeziwe nsuku zonke.
Esiteshini sikagesi esisophahleni esingu-5.5kW esiqale ukusebenza ngo-2017, zombili izintambo zithintwa indawo yokukhosela yezihlahla ezizungezile, futhi ukukhiqizwa kukagesi kungaphansi kwezinga elivamile.
Ngokwesimo sangempela sokuvikela esizeni, ukumodela nokuhlaziya kwenziwa ku-pvsyst.Lezi zintambo ezimbili zinengqikithi yamamojula we-photovoltaic angu-20, azofakwa umthunzi izinyanga ezingu-10 zonyaka, ukunciphisa ngokungathí sina ukukhiqizwa kwamandla kohlelo lonke.Ukufingqa, i-photovoltaic power optimizer ifakwe ochungechungeni olubili lwamamojula angama-20 kusayithi lephrojekthi.
Ngemuva kokuthi izithuthukisi zamandla e-photovoltaic ezingama-20 zifakwe entanjeni ezimbili, ngokuqhathanisa ukukhiqizwa kwamandla ezinsukwini ezi-5 libalele ngaphambi nangemuva kokufakwa, ukuhlaziya kungokulandelayo:
Usuku lokuqala lokusebenza kwe-optimizer kwakungu-December 30, ngesikhathi esifanayo, ingxenye empunga yokukhiqiza amandla eqembu lokuqhathanisa yengezwa ukuze kuhlaziywe ukuze kukhishwe ithonya lemisebe, izinga lokushisa nokunye ukuphazamiseka.Ngemva kokufakwa kwe-optimizer, isilinganiso sokwanda kokukhiqizwa kwamandla singama-39.13%, futhi isilinganiso sokunyuka kwamandla nsuku zonke singu-6.47 KWH.
Isiteshi sikagesi esiphakathi kwe-2MW, ukuphehlwa kukagesi kwamaqembu amane endaweni yokuthuthukisa kunyuswe ngo-105.93%, kukhiqize ugesi ongu-29.28 KWH owengeziwe nsuku zonke.
Okwesiteshi sikagesi esiphakathi kwezintaba esingu-2MW esiqale ukusebenza ngo-2015, isivikelo sethunzi esisendaweni siyinkimbinkimbi, esihlukaniswe ikakhulukazi izingxenye ezintathu: ukuvikela isigxobo samandla, ukuvikela isihlahla kanye nokuhlukanisa okuncane kakhulu kwezingxenye zangaphambili nangemuva.Ukuvikela imigqa yangaphambili nangemuva yezingxenye kuzovela ebusika ngoba i-engeli yobude belanga iba phansi, kodwa hhayi ehlobo.Ukufiphaliswa kwesigxobo kanye nokufihlwa kwesihlahla kwenzeka unyaka wonke.
Imodeli yesistimu yonke isungulwe ku-pvsyst ngokuvumelana nemingcele yemodeli yezingxenye kanye nama-inverters ohlelweni, indawo yephrojekthi kanye nesimo esithile sokuba nomthunzi.Ezinsukwini ezinelanga, ukulahleka komugqa kwemisebe yokukhanya kungu-8.9%.Inani lethiyori alinakutholwa ngenxa yokulahlekelwa ukukhiqizwa kwamandla okungafani okubangelwa ukungahambisani.
Ngokwezimo zesayithi, izintambo ezine zikhethiwe, izithuthukisi zamandla ze-photovoltaic ezingu-22 zifakwe kuchungechunge ngalunye, futhi inani eliphelele lama-optimizers angu-88 lifakiwe.Ngokuqhathanisa ukuphehlwa kwamandla ngaphambi nangemuva kokufakwa kanye nokukhiqizwa kwamandla kwezintambo ze-optimizer ezingafakiwe eziseduze, ukuhlaziya kungokulandelayo:
Ezinsukwini libalele, ukuphazamiseka kokushiswa kwemisebe yesimo sezulu kufanele kuncishiswe, futhi ingxenye empunga yokukhiqiza amandla ochungechunge lweqembu lokuqhathanisa kufanele yengezwe ukuze kuhlaziywe ukuze kuqedwe umthelela wenani lemisebe, izinga lokushisa kanye nokunye ukuphazanyiswa.Ngemva kokufakwa kwe-optimizer, ukukhiqizwa kwamandla kwesiteshi sikagesi kuphakeme ngo-105.93% kunalokho ngesikhathi singafakiwe, isilinganiso sokuphehlwa kwamandla ngentambo ngayinye ngosuku sikhuphuka ngo-7.32 KWH, futhi ukukhiqizwa kwamandla kwezintambo ezine zikhuphuke ngo-29.28 KWH ngosuku.
Ngenxa yokunciphisa iziteshi ezinkulu zamandla ayisicaba kanye nobunzima bezinsiza kanye nemvelo efana nezintaba, kunconywa ukuthi abantu abaningi basebenzise indawo yophahla ukuze kufakwe uhlelo lwe-photovoltaic.Sizohlinzeka ngohlelo oluphelele lokufakwa kwesistimu kanye nohlelo lokuhlanza amaphaneli elanga alandelayo.Sizohlala sizibophezele ekunikezeni abasebenzisi amandla e-photovoltaic aphephile, azinzile futhi athembekile.
