Ngeukuthuthukiswa okusheshayo kokusabalalisa i-photovoltaic, uphahla oluningi kakhulu "lugqoke i-photovoltaic" futhi lube yimithombo eluhlaza yokukhiqiza amandla. Ukukhiqizwa kwamandla kwesistimu ye-PV kuhlobene ngokuqondile nemali engenayo yokutshalwa kwezimali yesistimu, indlela yokuthuthukisa ukukhiqizwa kwamandla okugxilwe kuyo yonke imboni.
1. Umehluko ekukhiqizeni amandla ophahleni olunama-orientation ahlukene
Njengoba sonke sazi, ukuqondiswa okuhlukile kwamamojula we-photovoltaic kuthola ukukhanya kwelanga kuzohluka, ngakho-ke ukukhiqizwa kwamandla wezinhlelo ze-photovoltaic kanye ne-photovoltaic module orientation kunesixhumanisi esiseduze. Ngokusho kwedatha, endaweni ephakathi kwe-35 ~ 40 ° N latitude, isibonelo, i-irradiance etholwe ophahleni nge-orientation ehlukene kanye ne-azimuth ihlukile: kucatshangwa ukuthi ukukhiqizwa kwamandla ophahleni olubheke eningizimu kuyi-100, ukukhiqizwa kwamandla ophahleni olubheke empumalanga nasentshonalanga cishe ku-80, futhi umehluko ekukhiqizeni amandla angaba ngu-20%. Njengoba i-engeli isuka eningizimu ukuya empumalanga nasentshonalanga, ukukhiqizwa kwamandla kuzokwehla.
Ngokuvamile, ukusebenza kahle okuphezulu kakhulu kokukhiqizwa kwamandla kwesistimu kufinyelelwa engxenyeni esenyakatho nenkabazwe ngokuma kwayo eningizimu kanye ne-engeli engcono kakhulu yokuthambekela. Kodwa-ke, ekusebenzeni, ikakhulukazi ku-photovoltaic esabalalisiwe, ngezimo zesakhiwo sesakhiwo kanye nemikhawulo yendawo yesehlakalo, amamojula we-photovoltaic ngokuvamile awakwazi ukufakwa ku-orientation engcono kakhulu kanye ne-angle yokutsheka engcono kakhulu, i-multi-orientation yengxenye isibe enye yezindawo zobuhlungu zokukhiqiza amandla ophahleni lwe-photovoltaic, ngakho-ke indlela yokugwema ukulahlekelwa amandla okukhiqiza amandla okulethwa yi-multi-orientation yenkinga, isibe enye inkinga.
2. "Umphumela webhodi elifushane" ophahleni lwe-multi-directional
Kuhlelo lwe-inverter lwentambo evamile, amamojula axhunywe ochungechungeni, futhi ukusebenza kahle kwawo kokukhiqiza amandla kukhawulelwe "umphumela webhodi elifushane." Uma uchungechunge lwamamojula lusatshalaliswa kuma-orientation amaningi ophahleni, ukusebenza kahle kokukhiqizwa kwamandla okuncishisiwe kweyodwa yamamojula kuzothinta ukukhiqizwa kwamandla kwawo wonke uchungechunge lwamamojula, ngaleyo ndlela kuthinte ukusebenza kahle kokukhiqizwa kwamandla kokuma kophahla oluningi.
I-Micro inverter isebenzisa umklamo ophelele wesifunda ohambisanayo, onomsebenzi ozimele we-power point tracking (MPPT), ongasusa ngokuphelele "umphumela webhodi elifushane" futhi uqinisekise ukuthi imodyuli ngayinye isebenza ngokuzimela futhi ukukhiqizwa kwamandla akuphazamisi, uma kuqhathaniswa nesistimu ye-inverter yezintambo zendabuko, ngaphansi kwezimo ezifanayo, ingakwazi ukukhiqiza amandla angu-5% ~ 25% ngaphezulu futhi ithuthukise imali engenayo yokutshala izimali.
Ngisho noma amamojula efakwe ophahleni ngezimo ezihlukene, ukuphuma kwemodyuli ngayinye kungenziwa elungiselelwe eduze nendawo enkulu yamandla, ukuze uphahla oluningi "lugqoke i-PV" futhi lukhiqize inani eliningi.
3. I-Micro-inverter ekusetshenzisweni kophahla lwe-multi-directional
Ama-inverter ama-Micro, anezinzuzo zawo ezihlukile zobuchwepheshe, afaneleka kakhulu ezinhlelweni ze-PV zophahla olunezinhlangothi eziningi, futhi asebenze amazwe nezifunda ezingaphezu kwe-100, ehlinzeka ngezixazululo zobuchwepheshe zemojula ye-MLPE ye-PV yophahla olunezinhlangothi eziningi.
4. Iphrojekthi ye-PV Yasekhaya
Muva nje, iphrojekthi ye-PV yesistimu engu-22.62kW yakhiwe eBrazil. Ekuqaleni komklamo wephrojekthi, umnikazi ulindele Ngemva kokuklama iphrojekthi, amamojula we-PV ekugcineni afakwe ophahleni oluyisikhombisa lwe-orientation ehlukene, futhi ngokusetshenziswa kwemikhiqizo ye-micro-inverter, uphahla lwalusetshenziswa ngokugcwele. Ekusebenzeni kwangempela kwesitshalo samandla, okuthintekayo yi-orientation eminingi, inani lemisebe yelanga etholwe amamojula ophahleni oluhlukene liyahlukahluka, futhi amandla abo okukhiqiza amandla ahluka kakhulu. Thatha amamojula ayindilinga emfanekisweni ongezansi njengesibonelo, uphahla olubheke kabili oluyindilinga ngokubomvu nokuluhlaza okwesibhakabhaka luhambisana nezinhlangothi ezisentshonalanga nasempumalanga ngokulandelana.
5. Imiklamo ye-PV yezentengiso
Ngaphezu kwamaphrojekthi okuhlala, ama-inverter amancane nawo asetshenziswa ezinhlelweni zezentengiselwano nezimboni ngenkathi ebheke ophahleni. Ngonyaka odlule, iphrojekthi ye-PV yezohwebo nezimboni yafakwa ophahleni lwesuphamakethe eGoits, eBrazil, enamandla afakiwe angu-48.6 kW. Ekuqaleni komklamo nokukhetha kwephrojekthi, indawo izungezwe esithombeni esingezansi. Ngokusekelwe kulesi simo, iphrojekthi ikhethe yonke imikhiqizo ye-micro-inverter, ukuze ukukhiqizwa kwamandla emoduli yophahla ngalunye kungathinti omunye nomunye, ukuqinisekisa ukusebenza kahle kokukhiqizwa kwamandla kwesistimu.
Ukuma okuningi sekube esinye isici esibalulekile se-PV yophahla olusabalalisiwe namuhla, futhi ama-inverter amancane anomsebenzi we-MPPT weleveli yengxenye ngokungangabazeki ayisinqumo esifaneleka kakhulu sokubhekana nokulahlekelwa kwamandla okubangelwa ukuqondiswa okuhlukile. Qoqa ukukhanya kwelanga ukuze kukhanyise wonke amagumbi omhlaba.
