The difference between grid-connected and off-grid solar power systems

Imirasire y'izubasitasiyo y'amashanyarazi igabanijwemosisitemu yo hanze (yigenga) sisitemuna sisitemu ihujwe na gride, none ndakubwira itandukaniro riri hagati yibi: Mugihe abakoresha bahisemo gushiraho amashanyarazi akomoka ku mirasire y'izuba, bagomba kubanza kwemeza ikoreshwa rya sitasiyo y’amashanyarazi akomoka ku mirasire y'izuba cyangwa amashanyarazi akomoka ku mirasire y'izuba. , imikoreshereze yimirimo ibiri ntabwo ihwanye rwose, birumvikana ko ibigize amashanyarazi akomoka ku mirasire y'izuba bitameze kimwe, ikiguzi nacyo kiratandukanye cyane.

(1)Off-gridamashanyarazi akomoka ku mirasire y'izuba, azwi kandi ku izina ry’amashanyarazi yigenga, ni sisitemu idashingira ku mashanyarazi kandi ikora mu bwigenge. Igizwe ahanini nizuba ryamashanyarazi yizuba, bateri zibika ingufu, kwishyuza no gusohora ibintu, inverter nibindi bice. Amashanyarazi atangwa na panneaux solaire yumuriro w'amashanyarazi atembera muri bateri kandi arabikwa. Iyo bikenewe gutanga ingufu z'amashanyarazi, umuyoboro utaziguye muri bateri unyura muri inverter hanyuma ugahinduka 220V isimburana, ikaba isubiramo inshuro yo kwishyuza no gusohora. Ubu bwoko bw'amashanyarazi akomoka ku mirasire y'izuba bukoreshwa cyane kuko butagarukira ku karere. Irashobora gushyirwaho no gukoreshwa ahantu hose izuba riva. Kubwibyo, irakwiriye cyane ahantu hitaruye hatagira amashanyarazi, ibirwa byitaruye, ubwato bwuburobyi, ubworozi bwo hanze, kandi birashobora no gukoreshwa nkibikoresho bitanga amashanyarazi byihutirwa mubice bifite umuriro mwinshi.

Amashanyarazi akomoka ku mirasire y'izuba adafite amashanyarazi angana na 30-50% by'igiciro cya sisitemu yo kubyara kuko igomba kuba ifite bateri. Kandi ubuzima bwa serivisi ya bateri muri rusange mumyaka 3-5, nyuma igomba gusimburwa, byongera ikiguzi cyo gukoresha. Mu bijyanye n'ubukungu, biragoye kubona intera nini yo kuzamurwa no kuyikoresha, ntabwo rero ikwiriye gukoreshwa ahantu amashanyarazi yoroshye.

Ariko, ifite imbaraga zikomeye kumiryango mu bice bidafite amashanyarazi cyangwa umuriro w'amashanyarazi kenshi. Cyane cyane kugirango ukemure ikibazo cyamatara mugihe amashanyarazi yananiwe, urashobora gukoresha amatara azigama ingufu za DC, bifatika. Kubwibyo, amashanyarazi akomoka ku mirasire y'izuba adafite amashanyarazi ni ay'umwihariko kugira ngo akoreshwe ahantu hatagaragara cyangwa mu turere dufite umuriro w'amashanyarazi.

(2)Imiyoboroamashanyarazi akomoka ku mirasire y'izuba bisobanura ko igomba guhuzwa na gride rusange, bivuze ko amashanyarazi akomoka ku mirasire y'izuba, umuyoboro w'amashanyarazi murugo hamwe na gride rusange. Ubu ni amashanyarazi akomoka ku mirasire y'izuba agomba kwishingikiriza kumashanyarazi ariho kugirango akore. Ahanini igizwe nizuba ryamashanyarazi yizuba hamwe na inverter, amashanyarazi akomoka kumirasire y'izuba yahinduwe 220V-380V na inverter

Ubundi buryo bukoreshwa nabwo bukoreshwa mugukoresha ibikoresho byo murugo. Iyo imirasire y'izuba hejuru yinzu itanga amashanyarazi menshi kuruta ibikoresho bikoreshwa, ibirenga byoherezwa kumurongo rusange. Iyo ibisohoka murugo amashanyarazi yamashanyarazi adashobora guhaza ibikenerwa mubikoresho byo murugo, birahita byuzuzwa kuva kuri gride. Inzira yose igenzurwa mubwenge, nta muntu uhindura cyangwa uzimye.
