Iziteshi zamandla e-solar photovoltaic zihlukaniswa zaba amasistimu angaphandle kwegridi (ezimele) kanye nezinhlelo ezixhunywe kugridi. Uma abasebenzisi bekhetha ukufaka iziteshi zamandla elanga elanga, kufanele baqale baqinisekise ukuthi basebenzise amasistimu e-photovoltaic acishiwe noma amasistimu e-solar photovoltaic axhumeke kugridi. Izinjongo zalokhu okubili zihlukile, okokusebenza okukhona kuhlukile, futhi-ke, izindleko nazo zihluke kakhulu. Namuhla, ngikhuluma kakhulu ngohlelo lokukhiqiza amandla elanga angekho kugridi.
Isiteshi samandla se-solar photovoltaic esingaphandle kwegridi, esaziwa nangokuthi isiteshi samandla esizimele se-photovoltaic, siwuhlelo olusebenza ngokuzimela ngaphandle kwegridi yamandla. Ikakhulukazi yakhiwe ngamaphaneli we-solar photovoltaic, amabhethri okugcina amandla, izilawuli zokushaja nokukhipha, ama-inverters nezinye izingxenye. Ugesi okhiqizwa amaphaneli elanga e-photovoltaic ugeleza ngqo ebhethri futhi ugcinwe. Uma kudingekile ukunikeza amandla ezintweni zikagesi, i-DC yamanje ebhethrini iguqulwa ibe ngu-220V AC ngokusebenzisa inverter, okuwumjikelezo ophindaphindiwe wokushaja kanye nenqubo yokukhipha.
Lolu hlobo lwesiteshi samandla elanga se-photovoltaic lusetshenziswa kabanzi ngaphandle kwemikhawulo yendawo. Ingafakwa futhi isetshenziswe nomaphi lapho kunokukhanya kwelanga. Ngakho-ke, ifaneleka kakhulu ezindaweni ezikude ngaphandle kwamagridi kagesi, iziqhingi ezingazodwa, izikebhe zokudoba, izisekelo zokuzalanisa zangaphandle, njll. Ingasetshenziswa futhi njengemishini yokuphehla ugesi ezimeni eziphuthumayo ezindaweni ezivame ukunqamuka kukagesi.
Iziteshi zamandla elanga ze-photovoltaic ezingaphandle kwegridi kufanele zifakwe amabhethri, ezibalelwa ku-30-50% wezindleko zohlelo lokuphehla ugesi. Futhi impilo yesevisi yebhethri ngokuvamile iyiminyaka engu-3-5, bese kufanele ishintshwe, okwandisa izindleko zokusebenzisa. Mayelana nomnotho, kunzima ukukhuthaza nokusebenzisa ezinhlobonhlobo, ngakho-ke akufanelekile ukusetshenziswa ezindaweni lapho ugesi ulula khona.
Kodwa-ke, emindenini esezindaweni ezingenawo amagridi kagesi noma izindawo lapho ugesi enqamuka njalo, ukukhiqizwa kwamandla elanga angekho kugridi kunokusebenza okuqinile. Ikakhulukazi, ukuze kuxazululwe inkinga yokukhanyisa uma kwenzeka ukwehluleka kwamandla, izibani zokulondoloza amandla ze-DC zingasetshenziswa, okuyinto elula kakhulu. Ngakho-ke, ezimweni eziningi, amandla elanga e-photovoltaic angaphandle kwegridi asetshenziswa ezindaweni ezingenawo amagridi kagesi noma izindawo ezivame ukucisha ugesi.
