Ngeuphuhliso olukhawulezayo lokusasaza i-photovoltaic, uphahla oluninzi nangaphezulu "lunxibe i-photovoltaic" kwaye lube ngumthombo oluhlaza wokuvelisa amandla.Ukuveliswa kwamandla kwenkqubo ye-PV ihambelana ngokuthe ngqo kwingeniso yotyalo-mali yenkqubo, indlela yokuphucula inkqubo yokuvelisa amandla kugxininiso lweshishini lonke.
1. Umahluko kumandla okuvelisa amaphahla aneendlela ezahlukeneyo zokuqhelaniswa
Njengoko sonke siyazi, i-orientation eyahlukeneyo yeemodyuli ze-photovoltaic ifumana ukukhanya kwelanga kuya kuba yinto eyahlukileyo, ngoko ke ukuveliswa kwamandla kweenkqubo ze-photovoltaic kunye ne-photovoltaic module orientation inonxibelelwano olusondeleyo.Ngokutsho kwedatha, kwindawo ephakathi kwe-35 ~ 40 ° N ububanzi, umzekelo, i-irradiance efunyenwe ngamaphahla ngeendlela ezahlukeneyo kunye ne-azimuth iyahluka: ucinga ukuba ukuveliswa kwamandla ophahleni olujongene nezantsi luyi-100, ukuveliswa kwamandla uphahla olujonge ngasempuma nolujonge ngasentshona lumalunga nama-80, kwaye umahluko kwimveliso yamandla unokuba malunga ne-20%.Njengoko i-engile itshintsha ukusuka kumzantsi ukuya empuma nasentshona, ukuveliswa kwamandla kuya kuhla.
Xa sithetha ngokubanzi, obona buchule buphezulu bokuvelisa amandla kwesixokelelwano buphunyezwa kwi-hemisphere esemantla ngokuma okumazantsi okufanelekileyo kunye neyona engile yokuthambekela.Nangona kunjalo, ekusebenzeni, ngokukodwa kwi-photovoltaic esasazwayo, ngeemeko zokwakheka kwesakhiwo kunye nezithintelo zendawo, iimodyuli ze-photovoltaic kaninzi azikwazi ukufakwa kwi-orientation engcono kunye neyona angle yokuthambeka, icandelo le-multi-orientation liye laba yinkqubo ye-photovoltaic yophahla. iindawo ezibuhlungu zokuvelisa amandla, ngoko indlela yokuphepha ilahleko yokuvelisa amandla eziswa zii-multi-orientation, ibe yenye ingxaki ekuphuhlisweni koshishino.
2. "Impembelelo yebhodi emfutshane" kwiiphahla ezininzi
Kwinkqubo yokuguqula umtya wemveli, iimodyuli ziqhagamshelwe kuthotho, kwaye ukusebenza kakuhle kwazo kokuvelisa amandla kuthintelwe “yimpembelelo yebhodi emfutshane.”Xa umtya weemodyuli usasazwa kwiindlela ezininzi zephahla, ukunciphisa amandla okuvelisa amandla enye yeemodyuli kuya kuchaphazela ukuveliswa kwamandla oluhlu olupheleleyo lweemodyuli, ngaloo ndlela kuchaphazela amandla okuvelisa amandla okuqhelaniswa nophahla oluninzi.
I-Micro inverter ithatha uyilo olupheleleyo lwesekethe ehambelanayo, kunye nomsebenzi ozimeleyo wokulandelela amandla aphezulu (MPPT), onokuphelisa ngokupheleleyo "impembelelo yebhodi emfutshane" kwaye iqinisekise ukuba imodyuli nganye isebenza ngokuzimeleyo kwaye ukuveliswa kwamandla akuchaphazeli omnye nomnye, xa kuthelekiswa nomtya wendabuko. inkqubo ye-inverter, phantsi kweemeko ezifanayo, inokuvelisa i-5% ~ 25% amandla amaninzi kunye nokuphucula ingeniso yotyalo-mali.
Nangona iimodyuli zifakwe kwiiphahla ezineendlela ezahlukeneyo zokuqhelaniswa, ukuveliswa kwemodyuli nganye kunokulungiswa kufuphi nendawo ephezulu yamandla, ukwenzela ukuba uphahla olungaphezulu "lunxibe i-PV" kwaye luvelise ixabiso elingakumbi.
3. I-Micro-inverter kwisicelo sephahla le-multi-directional
I-Micro inverters, kunye nezibonelelo zabo ezizodwa zobugcisa, zifanelekile ngokugqithisileyo kwizicelo ze-PV ze-rooftop multi-directional, kwaye zisebenze kumazwe angaphezu kwe-100 kunye nemimandla, zibonelela ngezisombululo zobugcisa zemodyuli ye-MLPE ye-PV yophahla olunezikhokelo ezininzi.
4. Iprojekthi yePV yasekhaya
Kutshanje, inkqubo yePV yeprojekthi ye-22.62kW yakhiwe eBrazil.Ekuqaleni koyilo lweprojekthi, umnini ulindele Emva koyilo lweprojekthi, iimodyuli ze-PV zagqitywa ekugqibeleni kwiiphahla ezisixhenxe zeendlela ezahlukeneyo zokuqhelaniswa, kunye nokusetyenziswa kwemveliso ye-micro-inverter, uphahla lusetyenziswe ngokupheleleyo.Kumsebenzi wangempela weplanti yamandla, echaphazelekayo ngeendlela ezininzi zokuqhelaniswa, ubungakanani bemitha yelanga efunyenwe kwiimodyuli eziphahleni ezahlukeneyo ziyahluka, kwaye amandla abo okuvelisa amandla ahluka kakhulu.Thatha iimodyuli ezijikelezileyo kumzobo ongezantsi njengomzekelo, uphahla olujongene nolujikelezwe ngombala obomvu kunye nohlaza okwesibhakabhaka luhambelana nentshona kunye namacala asempuma ngokulandelanayo.
5. Iiprojekthi zePV zorhwebo
Ukongeza kwiiprojekthi zokuhlala, ii-inverters ezincinci zikwasetyenziswa kwizicelo zorhwebo kunye nezoshishino ngelixa zijongene nophahla.Kulo nyaka uphelileyo, iprojekthi yePV yorhwebo nezoshishino yafakelwa kuphahla lwevenkile enkulu eGoits, eBrazil, enomthamo oyi-48.6 kW.Ekuqaleni koyilo lweprojekthi kunye nokukhetha, indawo ijikelezwe kumzobo ongezantsi.Ngokusekelwe kule meko, iprojekthi ikhethe zonke iimveliso ze-micro-inverter, ukwenzela ukuba ukuveliswa kwamandla kwimodyuli yophahla ngalunye akuchaphazeli omnye nomnye, ukuqinisekisa ukusebenza kakuhle kokuveliswa kwamandla kwenkqubo.
Ukuqhelaniswa okuninzi kuye kwaba lolunye uphawu olubalulekileyo lwe-PV yophahla olusasazwayo namhlanje, kwaye ii-inverters ezincinci kunye nomsebenzi we-MPPT wecandelo ngokungathandabuzekiyo lukhetho olufanelekileyo ngakumbi ukujamelana nokulahlekelwa kwamandla okubangelwa ukuqhelaniswa okuhlukeneyo.Qokelela ukukhanya kwelanga ukuze kukhanyisele iimbombo zonke zehlabathi.
