Xa ilanga lasehlotyeni litshisa umhlaba, izitishi zamandla ze-PV ziqala ixesha lokuvelisa umbane elixakekileyo lonyaka. Nangona kunjalo, emva kokukhanya okuqaqambileyo, amaqondo obushushu aphezulu, imitha enamandla, kunye nezinye iindawo ezinzima zibonelela ngemiqobo engakaze ibonwe ngaphambili ekusebenzeni nasekugcinweni kwezitishi zamandla elanga. Ukuqinisekisa ukuba izitishi zamandla ze-PV zinokusebenza ngokufanelekileyo nangokuthe ngcembe kwindawo enzima kangaka, eli nqaku liza kuhlola iingxaki eziqhelekileyo ezidibana nazo ngexesha lokusebenza nokugcinwa kwezitishi zamandla ze-PV ehlotyeni kwaye likunike uthotho lwezisombululo ezijolise ekukuncedeni ukuba ujongane lula nemingeni yokuqinisekisa imveliso ezinzileyo yamandla aluhlaza.
Okokuqala, ukusebenza kakuhle kweemodyuli ze-PV kuncipha kwindawo enobushushu obuphezulu.
Amaqondo obushushu aphezulu ehlotyeni anokunyusa ngokulula ubushushu bomphezulu weemodyuli ze-PV, nto leyo enciphisa ukusebenza kakuhle kokuguqulwa kombane. Ukujongana nale ngxaki, abasebenzi abasebenza kunye nabalungisa iziko lombane banokuthatha ezi nkqubo zilandelayo.
Ukucoca umphezulu weemodyuli ze-PV rhoqo kunciphisa ukuqokelelwa kothuli kunye nokungcola kwaye kuphucula izinga lokudluliselwa kokukhanya.
Ukuze unciphise ubushushu bomphezulu weemodyuli ze-PV, faka izixhobo zomthunzi ngaphezulu kwazo, ezifana neenethi zomthunzi welanga okanye iibhodi zomthunzi welanga.
Ukuze unciphise impembelelo efanayo yemitha yobushushu phakathi kwezinto, phucula ulwakhiwo lwesikhululo samandla ngokuyila i-engile yokuthambekela kwezixhobo, isithuba semigca, kunye nezinye iimpawu ngokufanelekileyo.
Okwesibini, ukufudumala kwe-Inverter kunciphisa ukusebenza.
Ii-inverters zezinye zezona zixhobo zibalulekileyo kwisikhululo samandla se-PV, kwaye ukusebenza kwazo kunefuthe ngqo ekusebenzeni kakuhle kwesikhululo samandla. Amaqondo obushushu aphezulu ehlotyeni anokubangela ukuba i-inverter ishushu kakhulu kwaye ilahlekelwe kukusebenza. Ukujongana nale ngxaki, abasebenzi bokusebenza kunye nokulungisa banokuthatha la manyathelo alandelayo:
Yomeleza uyilo lokusasaza ubushushu lwe-inverter ngokwandisa ifeni yokusasaza ubushushu, uphucule isinki yobushushu, njalo njalo.
Jonga imeko yokusebenza kwe-inverter rhoqo, kwaye usule uthuli kunye nokungcola kwi-radiator njengoko kufuneka.
Misela isigqubuthelo esijikeleze i-inverter ukuze wehlise ubushushu obungqongileyo.
Okwesithathu, ukuguga ngokukhawuleza kwentambo.
Amaqondo obushushu aphezulu ehlotyeni kunye nemitha enamandla ye-ultraviolet inokukhawulezisa inkqubo yokwaluphala kwentambo, nto leyo enokubangela ukwaphuka kwe-insulation yentambo, i-short circuit, kunye neminye imiba. Ukuqinisekisa ukusebenza ngokukhuselekileyo kwentambo, abasebenzi abasebenza nabalungisayo banokuthatha la manyathelo alandelayo:
Ukukhetha izinto zekhebula ezinokumelana namaqondo obushushu aphezulu kunye nokuguga;
Jonga imeko yokwambathisa kunye nemeko yoqhagamshelo lweentambo rhoqo, kwaye utshintshe iintambo ezindala xa kuyimfuneko.
Faka izixhobo zokukhusela ilanga ezijikeleze intambo ukuze unciphise impembelelo yokukhanya kwe-UV.
Okwesine, ingozi ebangelwa ziindudumo kukhuseleko lwesikhululo samandla.
Ihlobo lixesha leemvula ezixhaphakileyo, kwaye imibane kunye neemvula zinokubangela umngcipheko omkhulu wokhuseleko kwisikhululo samandla se-PV. Ukuqinisekisa ukusebenza ngokukhuselekileyo kwesikhululo samandla, abasebenzi abasebenza kunye nabalungisayo banokuthatha la manyathelo alandelayo:
Faka iindlela zokukhusela umbane, njengeentonga zombane kunye neebhanti, ukukhusela izixhobo zesikhululo samandla ekubethweni ngumbane.
Hlola rhoqo ukusebenza kunye nemeko yezixhobo zokukhusela umbane ukuqinisekisa ukuba zisebenza kakuhle.
Lungiselela iimvula ezinamandla ngokuhlola indlela yokukhupha amanzi kunye neendlela zokuthintela ukungenwa kwamanzi kwizixhobo.
Okwesihlanu, i-insulation impedance yomhlaba iphantsi kakhulu.
Iingxaki ezininzi ziya kwenzeka phantsi kweemeko zemozulu ezimbi kakhulu ehlotyeni, umzekelo, izinto ezifumaneka kumanzi zebhokisi engangeni manzi zisenokungasebenzi. Xa sijongene nezi ngxaki, umyalezo wempazamo oqhelekileyo uthi "ukuthintela ukugquma komhlaba okuphantsi". Singasebenzisa isisombululo esikhawulezileyo:
Jonga iintambo ze-DC, isiseko secandelo, kunye namanzi kwi-casing. Iintambo ze-DC ezaphukileyo zezona zinto zixhaphakileyo ezibangela ubunzima bokuxinana kwe-insulation panel. Oku kuquka iintambo eziphakathi kweemodyuli, iintambo phakathi kweemodyuli kunye ne-inverter, ngakumbi iintambo ezikwiikona kunye neentambo ezishiywe ngaphandle ngaphandle kwepayipi, ekufuneka zihlolwe kakuhle.
Hlola i-DC okanye i-AC casing. Ukufaka iisleeve ngaphandle kwesithuba sokuvuza esiyilwe kwangaphambili okanye esibekwe ngendlela engafanelekanga kunokuvumela ukuba kubekho amanzi emvula amaninzi kwisleeve, nto leyo ebangela ukuba umgca ungangenisi ubushushu.
I-inverter ye-PV ayigalelwanga kakuhle. Ukuba i-inverter ayigalelwanga kakuhle okanye ayigalelwanga ngokwaneleyo, ayizukukwazi ukubona ngokufanelekileyo ixabiso le-insulation ye-component-to-ground, nto leyo ekhokelela kwizilumkiso zobuxoki.
Okwesithandathu, ukulahleka kombane osetyenziswayo.
Ehlotyeni, isibhakabhaka esiluhlaza okwesibhakabhaka kunye namafu amhlophe ahamba neenkqwithela ezingalindelekanga, kwaye ukucima kombane kwenzeka rhoqo, nto leyo eyenza kube yenye yemiyalezo yempazamo eqhelekileyo kwizikhululo zombane ze-PV. Ukuze sijongane nomba wokucima kombane, kufuneka senze uphando olucokisekileyo size sicebe izisombululo ezijoliswe kuzo.
Okokuqala, kufuneka siqinisekise ukuba umbane wegridi yombane uphukile na. Ukuba kufumaniseka ukuba igridi yombane ayiphumelelanga, ukhetho olulula nolucacileyo kukulinda igridi yombane ibuyisele umbane.
Nangona kunjalo, ukuba umbane wegridi ubonakala uqhelekile kodwa isikhululo samandla elanga siqhubeka nokuxela ukulahleka kwamandla ombane, kufuneka senze uphando oluthe kratya. Ukuqala, sebenzisa ifayile ye-AC voltage yemitha ezininzi ukuze ubone ukuba i-AC output voltage iqhelekile na, uqale nge-output port ye-inverter. Ukuba yonke into iqhelekile kwicala le-output ye-inverter, ingxaki inokuba kwicala le-AC yangaphandle, kwaye kufuneka sihlole iswitshi nganye yokhuseleko, efana neeswitshi zomoya, iigeyithi zeemela, izikhuseli ze-over-under-voltage, njl.njl., ukuqinisekisa ukuba aziqhekekanga okanye aziqhawulwanga.
Ngolu luhlu lokuhlolwa nokusombulula iingxaki, singayichonga ngokuchanekileyo imbangela yokucima kombane kwaye sithathe amanyathelo okulungisa afanelekileyo ukuqinisekisa ukusebenza okuzinzileyo kwesikhululo samandla elanga.
Okokugqibela, ukusebenzisa nokugcina izityalo zamandla elanga ngexesha lasehlotyeni kubangela iingxaki ezininzi kunye nobunzima. Nangona kunjalo, ngokusebenzisa iinkqubo ezikhankanyiweyo apha ngasentla, izityalo zamandla zingasetyenziswa ngokufanelekileyo nangokungaguquguqukiyo, kunye nokulawulwa ngokukhuselekileyo.
