1. Ngaba izithunzi zendlu, amagqabi kunye nenkunkuma yeentaka kwiimodyuli ze-pv ziya kuchaphazela inkqubo yokuvelisa amandla?
A: iiseli zePV ezivaliweyo ziya kusetyenziswa njengomthwalo.Amandla enziwe zezinye iiseli ezingavalwanga ziyakuvelisa ubushushu ngeli xesha, ekulula ukwenza isiphumo sendawo eshushu.Ngoko ukunciphisa ukuveliswa kwamandla kwenkqubo ye-PV, kunye nokutshisa iimodyuli ze-PV kwiimeko ezinzima.
2. Ngaba amandla aya nganelanga xa kubanda ebusika?
A: izinto ezichaphazela ngokuthe ngqo ukuveliswa kwamandla kukugqithiswa kwe-irradiation, ubude belanga kunye nokushisa okusebenzayo kweemodyuli ze-PV.Ebusika, ukunyanzeliswa kwe-irradiation kuya kuba buthathaka kwaye ixesha lokukhanya kwelanga liya kufinyezwa.Ke ngoko, ukuveliswa kombane kuya kuncitshiswa xa kuthelekiswa noko kusehlotyeni.Nangona kunjalo, inkqubo yokuvelisa amandla e-PV esasaziweyo iya kudityaniswa kwigridi yamandla.Ngethuba nje igridi yamandla inamandla, umthwalo wendlu awuyi kuba nokunqongophala kwamandla kunye nokungaphumeleli kwamandla.
3. Kutheni ukuveliswa kombane wePV kunokusetyenziswa ngokukhethekileyo?
A: Ukuveliswa kwamandla e-PV luhlobo lonikezelo lwamandla, olunokuvelisa amandla ombane, kwaye lunokuvelisa kuphela amandla ombane.Igridi yamandla ngumbane okhethekileyo, ongenakukwazi ukunika amandla ombane kuphela kumthwalo, kodwa ufumane amandla ombane njengomthwalo.Ngokomgaqo wokuba umbane ohamba ngoku usuka kwindawo ene-voltage ephezulu ukuya kwindawo ene-voltage ephantsi, xa ukuveliswa kwamandla e-PV, ngokwembono yomthwalo, I-voltage yegridi eqhagamshelwe i-inverter isoloko iphezulu kancinane kunegridi yamandla. , ngoko ke umthwalo unika kuqala ukuveliswa kwamandla ePV.Kuphela xa amandla e-PV engaphantsi kwamandla omthwalo, i-voltage ye-node parallel iya kuhla, kwaye igridi yamandla iya kunika amandla kumthwalo.
