Zihlala ixesha elingakanani ii-inverters zelanga zokuhlala?

Kwinxalenye yokuqala yolu ngcelele, imagazini ye-pv iphononongeubomi obunemveliso yeepaneli zelanga, ezikwaziyo ukunyamezela. Kule nxalenye, sivavanya ii-inverters zelanga zokuhlala kwiifom zazo ezahlukeneyo, ukuba zihlala ixesha elingakanani, kwaye zomelele kangakanani na.

I-inverter, isixhobo esiguqula amandla e-DC aveliswa ziipaneli zelanga zibe ngamandla asebenzisekayo e-AC, sinokuza ngeendlela ezimbalwa ezahlukeneyo.

Iintlobo ezimbini eziphambili ze-inverters kwizicelo zokuhlala ziinverters zentambo kunye ne-microinverters. Kwezinye izicelo, abaguquli beentambo baxhotyiswe ngemodyuli-level power electronics (MLPE) ebizwa ngokuba yiDC optimizers. I-Microinverters kunye ne-DC optimizers zisetyenziselwa uphahla kunye neemeko ze-shading okanye i-sub-optimal orientation (kungekhona emazantsi).

Kwizicelo apho uphahla lune-azimuth ekhethiweyo (ukuqhelaniswa nelanga) kunye nemibandela encinci ye-shading, inverter yomtya ingaba sisisombululo esihle.

Ii-inverters zentambo ngokubanzi ziza neengcingo ezilula kunye nendawo esembindini yokulungiswa lula ngamagcisa elanga.Ngokuqhelekileyo azibizi kakhulu,uthe Solar Reviews. Ii-inverters zinokuxabisa i-10-20% yofakelo lulonke lwepaneli yelanga, ngoko ke ukukhetha okulungileyo kubalulekile.

Zihlala ixesha elingakanani?

Ngelixa iiphaneli zelanga zinokuhlala iminyaka engama-25 ukuya kwengama-30 okanye ngaphezulu, ii-inverters zihlala zinobomi obufutshane, ngenxa yezinto eziguga ngokukhawuleza. Umthombo oqhelekileyo wokungaphumeleli kwi-inverters yi-electro-mechanical wear kwi-capacitor kwi-inverter. I-electrolyte capacitors inobomi obufutshane kunye nobudala ngokukhawuleza kunezixhobo ezomileyo,yatsho iSolar Harmonics.

Utshilo i-EnergySageukuba i-inverter yentambo yendawo yokuhlala eqhelekileyo iya kuhlala malunga ne-10-15 iminyaka, kwaye kuya kufuneka itshintshwe ngexesha elithile ngexesha lokuphila kweepaneli.

Iziguquli zentambongokubanzi babeiwaranti eqhelekileyo ukusuka 5-10 iminyaka, abaninzi kunye ukhetho ukwandisa ukuya 20 iminyaka. Ezinye iikhontrakthi zelanga ziquka ukugcinwa kwamahhala kunye nokubeka iliso ngexesha lekhontrakthi, ngoko kububulumko ukuvavanya oku xa ukhetha ii-inverters.

I-Microinverters inobomi obude, i-EnergySage ithe bahlala behlala iminyaka eyi-25, phantse ixesha elide njengabalingane babo bephaneli. I-Roth Capital Partners ithe abafowunelwa boshishino ngokubanzi banika ingxelo yokungaphumeleli kwe-microinverter ngesantya esisezantsi kakhulu kunee-inverters zentambo, nangona iindleko zangaphambili ziphezulu kancinci kwii-microinverters.

I-Microinverters ine-warranty yeminyaka engama-20 ukuya kwengama-25 ubudala ebandakanyiweyo. Kufuneka kuqatshelwe ukuba ngelixa ii-microinverters zinewaranti ende, zisebuchwephesha obutsha ukusuka kwiminyaka elishumi edlulileyo okanye kunjalo, kwaye kuya kuhlala kubonakala ukuba isixhobo siya kuzalisekisa isithembiso seminyaka engama-20 +.

Okufanayo kuya kwii-DC optimizers, ezidityaniswe ngokwesiqhelo ne-centralized string inverter. La macandelo enzelwe ukuhlala iminyaka engama-20-25 kwaye anewaranti yokuhambelana nelo xesha.

Ngokuphathelele ababoneleli be-inverter, iibrendi ezimbalwa zibamba isabelo esikhulu semakethi. EUnited States, Enphase inkokeli yemarike ye-microinverters, ngelixa i-SolarEdge ikhokelela kwii-inverters zentambo. I-Tesla iye yenza amaza kwindawo yokuhlala inverter yentambo, ithatha isabelo semarike, nangona isala kubonakala ukuba ingakanani impembelelo yokungena kwimarike yeTesla, yatsho inqaku leshishini elivela kwiRoth Capital Partners.

Iintsilelo

Uphononongo olwenziwa yi-kWh Analytics lufumene ukuba i-80% yokungaphumeleli koluhlu lwelanga lwenzeka kwinqanaba le-inverter. Zininzi izizathu zoku.

Ngokutsho kweFallon Solutions, unobangela omnye ziimpazamo zegridi. I-voltage ephezulu okanye ephantsi ngenxa yesiphambeko segridi inokubangela ukuba i-inverter iyeke ukusebenza, kwaye i-breaker circuit okanye i-fuses ingavulwa ukukhusela i-inverter ekungaphumeleli kwe-voltage ephezulu.

Ngamanye amaxesha ukungaphumeleli kunokwenzeka kwinqanaba le-MLPE, apho amacandelo e-optimizers amandla abonakaliswe kumaqondo okushisa aphezulu phezu kophahla. Ukuba imveliso encitshisiweyo ifunyenwe, inokuba yimpazamo kwi-MLPE.

Ufakelo kufuneka lwenziwe ngokufanelekileyo ngokunjalo. Njengomthetho wesithupha, i-Fallon iphakamise ukuba umthamo wepaneli yelanga kufuneka ufike kwi-133% yomthamo we-inverter. Ukuba iipaneli azihambelani ngokufanelekileyo kwi-inverter yesayizi elungileyo, aziyi kusebenza ngokufanelekileyo.

Isondlo

Ukugcina i-inverter isebenza ngokufanelekileyo ixesha elide, kunjalokucetyiswaukufakela isixhobo kwindawo epholileyo, eyomileyo enomoya omninzi ojikelezayo. Abafaki kufuneka baphephe iindawo ezinokukhanya kwelanga ngokuthe ngqo, nangona iibrendi ezithile zee-inverters zangaphandle ziyilelwe ukuba zimelane nokukhanya kwelanga ngakumbi kunabanye. Kwaye, kufakelo lwe-multi-inverter, kubalulekile ukuqiniseka ukuba kukho ucoceko olufanelekileyo phakathi kwe-inverter nganye, ukuze kungabikho ukuhanjiswa kobushushu phakathi kwee-inverters.

Yeyona ndlela ilungileyo yokuhlola umphandle we-inverter (ukuba iyafikeleleka) ngekota, uqinisekisa ukuba akukho zimpawu zibonakalayo zomonakalo, kwaye zonke ii-vents kunye nee-fins zokupholisa zikhululekile kubumdaka nothuli.

Kukwacetyiswa ukuba wenze ishedyuli yokuhlolwa ngesifakeli selanga esinelayisensi rhoqo emva kweminyaka emihlanu. Ukuhlolwa ngokuqhelekileyo kubiza i-$ 200- $ 300, nangona ezinye iikontraka zelanga zinesondlo samahhala kunye nokubeka iliso kwi-20-25 iminyaka. Ngexesha lokuhlolwa, umhloli kufuneka ajonge ngaphakathi kwi-inverter ngeempawu zokubola, umonakalo, okanye izinambuzane.
