Isistimu yelanga engaphandle kwegridi iyisistimu yamandla ezimele yona ekhiqiza futhi igcine ugesi, isebenza ngokuzimela ngaphandle kwegridi yamandla. Lolu hlobo lwesistimu luklanyelwe ukuhlinzeka ngamandla kagesi ezindaweni lapho uxhumo lwegridi lungatholakali futhi lungazinzi noma lapho izindleko zikagesi wegridi ziphezulu.

Isistimu yelanga engaphandle kwegridi ihlanganisa izingxenye ezibalulekile ezithwebula, ezigcina, futhi zisabalalise amandla elanga, okuhlanganisa amaphaneli elanga, isilawuli sokushaja, amabhethri elanga, kanye ne-inverter. Uhlelo lusebenza ngokusebenzisa amaphaneli elanga ukuze limunce amandla avela elangeni futhi liwaguqule libe amandla kagesi. Bese isilawuli seshaja silawula ukuhamba kwamandla futhi sishaje ibhethri lelanga ukuze ligcine amandla. Futhi i-inverter iguqulela amandla kugesi we-AC ukuze inike amandla izinto zikagesi ezisendlini.

Izindleko eziphelele zesistimu yelanga engaphandle kwegridi incike ezicini ezihlukahlukene ezifana nezidingo zamandla, izidingo zamandla aphezulu, ikhwalithi yemishini, izimo zokukhanya kwelanga zendawo, indawo yokufaka, ukugcinwa kwezindleko kanye nokushintshwa, njll. Ngokuvamile, amasistimu elanga amancane angaphandle kwegridi angakwazi isukela ku-$10,000 kuya ku-$30,000, amakhaya amaningi omkhaya asukela ku-$30,000 kuya ku-$45,000, futhi amakhaya amakhulu angaba ngamaRandi angu-50 000 kuya phezulu.

I-ROYPOW ihlinzeka ngezixazululo ezenziwe ngokwezifiso, ezithengekayo ngaphandle kwegridi yesolar ezihlanganiswe neziguquli eziphephile, ezisebenza kahle neziqinile ezingaphandle kwegridi kanye nezinhlelo zebhethri ukuze kunikezwe amandla ukuzimela kwamandla.

Nazi izinyathelo ezine ezinconyiwe ukuthi uzilandele:

Isinyathelo 1: Bala umthwalo wakho. Hlola yonke imithwalo (imishini yasendlini) futhi urekhode izidingo zayo zamandla. Udinga ukwenza isiqiniseko sokuthi yimaphi amadivayisi okungenzeka ukuthi avuliwe ngesikhathi esisodwa futhi ubale isamba somthwalo (umthwalo omkhulu).

Isinyathelo sesi-2: Ukulinganisa kwe-inverter. Njengoba ezinye izinto zikagesi zasendlini, ikakhulukazi lezo ezinamamotho, zizoba nokungena okukhulu kwamanje lapho uqalisa, udinga isiguquli esinesilinganiso esiphezulu somthwalo ofaniswe nenani eliphelele elibalwe kusinyathelo soku-1 ukuze uhlangabezane nomthelela wamanje wokuqalisa. Phakathi kwezinhlobo zayo ezihlukene, i-inverter enokukhishwa kwe-sine wave ehlanzekile iyanconywa ngokusebenza kahle nokuthembeka.

Isinyathelo sesi-3: Ukukhetha ibhethri. Phakathi kwezinhlobo ezinkulu zebhethri, inketho ethuthuke kakhulu namuhla ibhethri ye-lithium-ion, epakisha umthamo wamandla amaningi ngevolumu yeyunithi futhi inikeza izinzuzo ezifana nokuphepha okukhulu nokuthembeka. Bala ukuthi ibhethri elilodwa lizolayisha isikhathi esingakanani futhi mangaki amabhethri owadingayo.

Isinyathelo sesi-4: Ukubalwa kwenombolo yephaneli yelanga. Inombolo incike emithwalweni, ukusebenza kahle kwamaphaneli, indawo yendawo yamaphaneli ngokuphathelene ne-solar irradiance, ukuthambekela nokujikeleza kwamapaneli elanga, njll.

Nazi izinyathelo ezinconyiwe:

Isinyathelo 1: Thola izingxenye. Thenga izakhi, okuhlanganisa amaphaneli elanga, amabhethri, iziguquli, izilawuli zokushaja, izingxenyekazi zehadiwe ezikhwezwayo, izintambo, namagiya okuphepha abalulekile.

Isinyathelo sesi-2: Faka amaphaneli elanga. Faka amaphaneli ophahleni lwakho noma endaweni enokuchayeka elangeni. Zibophe ngokuphephile bese uzifake nge-engeli ukuze ukwandise ukumuncwa kwelanga.

Isinyathelo sesi-3: Faka isilawuli sokushaja. Misa isilawuli sokushaja eduze nebhethri endaweni engenisa umoya. Xhuma amaphaneli elanga kusilawuli usebenzisa izintambo zokukala ezifanele.

Isinyathelo sesi-4: Faka ibhethri. Xhuma ibhethri ngochungechunge noma ngokuhambisana ngokuya ngezidingo zamandla kagesi wesistimu yakho.

Isinyathelo sesi-5: Faka i-inverter. Beka i-inverter eduze kwebhethri bese uxhuma, uqinisekisa i-polarity efanele, futhi uxhumanise okukhiphayo kwe-AC ohlelweni lukagesi lwasekhaya.

Isinyathelo sesi-6: Xhuma futhi uhlole. Phinda uhlole konke ukuxhumana, bese unika amandla kusistimu yelanga. Gada isistimu ukuze uqinisekise ukusebenza kahle, wenze noma yiziphi izinguquko ezidingekayo.

Isistimu yelanga engaphandle kwegridi isebenza ngokuzimela ngaphandle kwegridi kagesi, ikhiqiza futhi igcine amandla anele ukuhlangabezana nezidingo zekhaya.

Isistimu yelanga ekugridi ixhunywe kugridi yensiza yendawo, ihlanganisa kalula amandla elanga ukuze isetshenziswe emini kuyilapho idonsa ugesi kugridi lapho amaphaneli elanga ekhiqiza amandla anganele, njengasebusuku noma ngezinsuku eziguqubala.

Amasistimu elanga angaphandle kwegridi kanye ne-on-grid anobuhle nobubi bawo obuhlukile. Ukukhetha phakathi kwe-off-grid kanye ne-on-grid solar system kuncike ezintweni ezithile, ezihlanganisa kodwa ezingagcini nje:

Isabelomali: Amasistimu elanga angaphandle kwegridi, kuyilapho enikeza ukuzimela okuphelele kugridi, eza nezindleko eziphezulu zangaphambili. Amasistimu elanga akugridi abiza kakhulu, njengoba angakwazi ukunciphisa izikweletu zikagesi zanyanga zonke futhi akwazi ukukhiqiza inzuzo.

Indawo: Uma uhlala endaweni yasemadolobheni ngokufinyelela kalula kugridi yokusetshenziswa, isistimu yelanga ekugridi ingahlanganisa ngaphandle komthungo nengqalasizinda yakho ekhona. Uma ikhaya lakho likude noma likude negridi yensiza eseduze, isistimu yelanga ye-off-grid ingcono, ngoba iqeda isidingo sezandiso zegridi ezibizayo.

Izidingo Zamandla: Ezindlini ezinkulu nezinethezekile ezinezidingo zamandla aphezulu, isistimu sonozungezilanga ekugridi ingcono, inikeza ikhophi yasenqolobaneni ethembekile ngezikhathi zokukhiqiza okuphansi kwelanga. Ngakolunye uhlangothi, uma unekhaya elincane noma uhlala endaweni evamise ukucisha ugesi noma ukuxhumeka kwegridi okungazinzile, isistimu yelanga engaphandle kwegridi iyindlela okufanele uhambe ngayo.

Yebo, kungenzeka ukusebenzisa iphaneli yelanga ne-inverter ngaphandle kwebhethri. Kulokhu kusetha, iphaneli yelanga iguqulela ukukhanya kwelanga kube ugesi we-DC, isiguquli esibe sesiwuguqula sibe ugesi we-AC ukuze sisetshenziswe ngokushesha noma sifakwe kugridi.

Nokho, ngaphandle kwebhethri, awukwazi ukugcina ugesi oweqile. Lokhu kusho ukuthi lapho ukukhanya kwelanga kunganele noma kungabikho, isistimu ngeke inikeze amandla, futhi ukusetshenziswa okuqondile kwesistimu kungaholela ekuphazamisekeni kwamandla uma ukukhanya kwelanga kushintshashintsha.

Ama-inverter amaHybrid ahlanganisa ukusebenza kwakho kokubili ama-inverter elanga nebhethri. Ama-inverter angaphandle kwegridi aklanyelwe ukusebenza ngokuzimela ngaphandle kwegridi yokusetshenziswa, ngokuvamile asetshenziswa ezindaweni ezikude lapho amandla egridi engatholakali noma engathembekile. Nansi umehluko obalulekile:

Uxhumano Lwegridi: Iziguquli ezihlanganisiwe zixhuma kugridi yensiza, kuyilapho iziguquli ze-off-grid zisebenza ngokuzimela.

Isitoreji Samandla: Ama-Hybrid inverter anokuxhumana kwebhethri eyakhelwe ngaphakathi ukuze agcine amandla, kuyilapho ama-inverter angaphandle kwegridi ethembele kuphela ekugcinweni kwebhethri ngaphandle kwegridi.

Amandla Ayisipele: Iziguquli ezihlanganisiwe zidonsa amandla ayisipele kugridi lapho imithombo yelanga nebhethri inganele, kuyilapho iziguquli ze-off-grid zithembele kumabhethri ashajwe ngamaphaneli elanga.

Ukuhlanganiswa Kwesistimu: Amasistimu e-Hybrid adlulisela amandla elanga engeziwe kugridi uma amabhethri eseshajwe ngokugcwele, kuyilapho amasistimu angaphandle kwegridi egcina amandla engeziwe kumabhethri, futhi uma egcwele, amaphaneli elanga kufanele ayeke ukukhiqiza amandla.

Ngokuvamile, Amabhethri amaningi elanga emakethe namuhla ahlala phakathi kweminyaka emihlanu neyi-15.

Amabhethri e-ROYPOW angekho kugridi asekela iminyaka engu-20 yokuphila kokuklama kanye nezikhathi ezingaphezu kuka-6,000 zempilo yomjikelezo. Ukuphatha ibhethri ngendlela efanele ngokunaka nokunakekelwa okufanele kuzoqinisekisa ukuthi ibhethri izofinyelela ubude bayo bempilo obuphelele noma ngaphezulu.

Amabhethri angcono kakhulu wezinhlelo zelanga ezingaphandle kwegridi yi-lithium-ion ne-LiFePO4. Kokubili kusebenza kahle kunezinye izinhlobo ezinhlelweni zokusebenza ezingaphandle kwegridi, enikeza ukushaja okusheshayo, ukusebenza okuphakeme, ubude bempilo, ukunakekelwa okuyiziro, ukuphepha okuphezulu, nomthelela ophansi kwezemvelo.
