Inkqubo yelanga ye-off-grid yinkqubo yamandla ezimeleyo eyenza kwaye igcine umbane, isebenza ngokuzimeleyo kwigridi yamandla. Olu hlobo lwenkqubo yenzelwe ukubonelela ngamandla ombane kwiindawo apho uxhulumaniso lwegridi alufumaneki kwaye lungazinzile okanye apho ixabiso lombane wegridi liphezulu.

Isixokelelwano selanga esingekho kwigridi sibandakanya izinto ezibalulekileyo ezithatha, zigcine, kwaye zisasaze amandla elanga, kubandakanywa iiphaneli zelanga, isilawuli sentlawulo, iibhetri zelanga kunye ne-inverter. Esi sixokelelwano sisebenza ngokusebenzisa iiphaneli zelanga ukufunxa amandla kukukhanya kwelanga kunye nokuwaguqula abe ngamandla ombane. Emva koko umlawuli wetshaja ulawula ukuhamba kwamandla kwaye uhlawule ibhetri yelanga ukugcina amandla. Kwaye i-inverter iguqula amandla kumbane we-AC ukunika amandla izixhobo ezisekhaya.

Ixabiso lilonke lenkqubo yelanga engaphandle kwegrid epheleleyo ixhomekeke kwizinto ezahlukeneyo ezifana neemfuno zamandla, iimfuno zamandla aphezulu, umgangatho wesixhobo, iimeko zelanga zendawo, indawo yokufakela, ukugcinwa kweendleko zokutshintsha, njl. ukusuka kwi-$10,000 ukuya kwi-$30,000, uninzi lwamakhaya eentsapho lusukela kwii-$30,000 ukuya kwii-$45,000, kwaye amakhaya amakhulu anokuba ukusuka kwii-$50,000 ukuya phezulu.

I-ROYPOW ibonelela ngezisombululo ezifikelelekayo, ezifikelelekayo ngaphandle kwegridi yelanga ezidityaniswe neziguquli ezikhuselekileyo, ezisebenzayo, nezizinzileyo ezingaphandle kwegridi kunye neenkqubo zebhetri ukunika amandla ukuzimela kwamandla.

Nanga amanyathelo amane acetyiswayo ukuba alandelwe:

Inyathelo 1: Bala umthwalo wakho. Jonga yonke imithwalo (izixhobo zasekhaya) kwaye urekhode iimfuno zabo zamandla. Kufuneka uqiniseke ukuba zeziphi izixhobo ezinokuthi zibekho ngaxeshanye kwaye ubale umthwalo opheleleyo (umthwalo ophezulu).

Inyathelo 2: Ubungakanani be-inverter. Kuba ezinye izixhobo zombane zasekhaya, ngakumbi ezo zineenjini, ziya kuba nesantya esikhulu sangoku xa uqalwa, ufuna isiguquli esinomlinganiselo ophakamileyo womthwalo ohambelana nenani lilonke elibalwe kwiNyathelo loku-1 ukulungiselela impembelelo yangoku yokuqalisa. Phakathi kweentlobo zayo ezahlukeneyo, i-inverter enemveliso ecocekileyo ye-sine wave iyacetyiswa ukusebenza kakuhle kunye nokuthembeka.

Inyathelo 3: Ukukhetha ibhetri. Phakathi kweentlobo ezinkulu zebhetri, ukhetho oluphezulu kakhulu namhlanje ibhetri ye-lithium-ion, epakisha umthamo wamandla amaninzi ngomthamo weyunithi kwaye inikezela ngeenzuzo ezifana nokhuseleko olukhulu kunye nokuthembeka. Bala ukuba ibhetri enye izakuqhuba ixesha elingakanani nomthwalo kunye nokuba ufuna iibhetri ezingaphi.

Inyathelo lesi-4: Ukubalwa kwenani lephaneli yelanga. Inani lixhomekeke kwimithwalo, ukusebenza kakuhle kweepaneli, indawo yendawo yeepaneli ngokubhekiselele kwi-radiance yelanga, ukuthambekela kunye nokujikeleza kweepaneli zelanga, njl.

Nanga amanyathelo acetyiswayo:

Inyathelo 1: Fumana amacandelo. Izinto ezithengiweyo, ezibandakanya iiphaneli zelanga, iibhetri, ii-inverters, izilawuli zokutshaja, ii-hardware ezifakwayo, iingcingo, kunye nezixhobo zokhuseleko ezibalulekileyo.

Inyathelo lesi-2: Faka iiphaneli zelanga. Beka iipaneli kuphahla lwakho okanye kwindawo enelanga elangeni. Zibophe ngokukhuselekileyo kwaye uzifake engile ukuze ukwandise ukufunxwa kukukhanya kwelanga.

Inyathelo lesi-3: Faka isilawuli sentlawulo. Beka isilawuli sokutshaja kufutshane nebhetri kwindawo engenamoya. Qhagamshela iiphaneli zelanga kwisilawuli usebenzisa iingcingo ezifanelekileyo zokulinganisa.

Inyathelo 4: Faka ibhetri. Qhagamshela ibhetri kuthotho okanye ngokunxuseneyo ngokweemfuno zombane wenkqubo yakho.

Inyathelo lesi-5: Faka i-inverter. Beka i-inverter kufuphi nebhetri kwaye uqhagamshele, uqinisekise i-polarity echanekileyo, kwaye udibanise imveliso ye-AC kwisistim yombane yekhaya lakho.

Inyathelo lesi-6: Qhagamshela kwaye uvavanye. Jonga kabini yonke imidibaniso, emva koko unike amandla kwisixokelelwano selanga. Ukubeka iliso kwinkqubo ukuqinisekisa ukusebenza ngokufanelekileyo, ukwenza naluphi na uhlengahlengiso oluyimfuneko.

Isixokelelwano selanga esingekho kwigridi sisebenza ngokuzimeleyo kuthungelwano lombane, sivelisa kwaye sigcina amandla awoneleyo okuhlangabezana neemfuno zekhaya.

Isixokelelwano selanga esikwigridi siqhagamshelwe kwigridi yosetyenziso lwasekhaya, idibanisa ngaphandle komthungo amandla elanga ukuze isetyenziswe emini ngelixa izoba umbane kwigridi xa iiphaneli zesola zivelisa amandla angonelanga, nje ebusuku okanye ngeentsuku ezinamafu.

I-off-grid kunye ne-on-grid iinkqubo zelanga zineenzuzo kunye neengxaki zazo ezizodwa. Ukhetho phakathi kwe-off-grid kunye ne-on-grid ye-solar system ixhomekeke kwizinto ezithile, kubandakanywa kodwa kungaphelelanga:

Uhlahlo lwabiwo-mali: Iinkqubo zelanga ezingaphandle kwegridi, ngelixa zibonelela ngokuzimela ngokupheleleyo kwigridi, ziza neendleko eziphezulu zangaphambili. Iinkqubo zesolar ezikwigridi zineendleko ezithe kratya, njengoko zinokunciphisa amatyala ombane wenyanga kwaye zibenako ukwenza inzuzo.

Indawo: Ukuba uhlala kwindawo yasezidolophini enokufikelela ngokulula kwigridi esetyenziswayo, inkqubo yelanga ekwigridi inokudibanisa ngaphandle komthungo kwiziseko zakho ezikhoyo. Ukuba ikhaya lakho likude okanye likude negridi yoncedo olusondeleyo, i-off-grid system yelanga ingcono, kuba iphelisa imfuno yokwandiswa kwegridi ebiza.

Izidingo zamandla: Kumakhaya amakhulu kunye namakhaya anqabileyo aneemfuno eziphezulu zombane, inkqubo yelanga ekwigridi ingcono, inikezela ngenkxaso ethembekileyo ngexesha lemveliso yelanga ephantsi. Ngakolunye uhlangothi, ukuba unekhaya elincinci okanye uhlala kwindawo ehlala ephuma umbane okanye uqhagamshelo lwegridi engazinzanga, i-off-grid solar system yindlela yokuhamba.

Ewe, kuyenzeka ukuba usebenzise iphaneli yelanga kunye ne-inverter ngaphandle kwebhetri. Kolu cwangciso, iphaneli yelanga iguqula ukukhanya kwelanga kube ngumbane we-DC, othi inverter iwuguqule ube ngumbane we-AC ukuze usetyenziswe ngoko nangoko okanye ukondla kwigridi.

Nangona kunjalo, ngaphandle kwebhetri, awukwazi ukugcina umbane ogqithisileyo. Oku kuthetha ukuba xa ukukhanya kwelanga kunganelanga okanye kungabikho, isixokelelwano asiyi kubonelela ngamandla, kwaye ukusetyenziswa ngokuthe ngqo kwesixokelelwano kunokukhokelela kukuphazamiseka kwamandla ukuba ukukhanya kwelanga kuyaguquguquka.

Ii-inverters zeHybrid zidibanisa imisebenzi yazo zombini ii-solar kunye nebhetri inverters. Iziguquli ze-off-grid zenzelwe ukusebenza ngokuzimeleyo kwigridi esetyenziswayo, esetyenziswa ngokuqhelekileyo kwiindawo ezikude apho amandla egridi engafumanekiyo okanye engathembekanga. Nantsi umahluko ophambili:

I-Grid Connectivity: I-Hybrid inverters idibanisa kwigridi yenkonzo, ngelixa i-off-grid inverters isebenza ngokuzimeleyo.

Ukugcinwa kwamandla: Ii-inverters ze-Hybrid ziye zakha uqhagamshelo kwibhetri yokugcina amandla, ngelixa ii-inverters ze-off-grid zixhomekeke kuphela kugcino lwebhetri ngaphandle kwegridi.

Amandla e-Backup: Abaguquleli be-Hybrid batsala amandla okugcina kwigridi xa imithombo yelanga kunye nebhetri ingonelanga, ngelixa ii-inverters ze-off-grid zixhomekeke kwiibhetri ezihlawuliswa iipaneli zelanga.

Ukuhlanganiswa kweNkqubo: Iinkqubo ze-Hybrid zihambisa amandla amaninzi elanga kwigridi emva kokuba iibhetri zihlawuliswe ngokupheleleyo, ngelixa iinkqubo ze-off-grid zigcina amandla amaninzi kwiibhetri, kwaye xa zigcwele, iipaneli zelanga kufuneka ziyeke ukuvelisa amandla.

Ngokuqhelekileyo, Uninzi lweebhetri zelanga kwimarike namhlanje zihlala phakathi kweminyaka emihlanu kunye ne-15.

Iibhetri ze-ROYPOW ngaphandle kwegrid zixhasa ukuya kuthi ga kwiminyaka engama-20 yobomi boyilo kunye namaxesha angaphezu kwama-6,000 obomi bomjikelo. Ukuphatha ibhetri ngokufanelekileyo ngokhathalelo olufanelekileyo kunye nokugcinwa kuya kuqinisekisa ukuba ibhetri iya kufikelela kubomi bayo obuphezulu okanye nangaphezulu.

Iibhetri ezilungileyo kakhulu kwiinkqubo zelanga ezingaphandle kwegridi yi-lithium-ion kunye ne-LiFePO4. Zombini zisebenza ngaphezu kwezinye iintlobo kwizicelo ezingaphandle kwegridi, zibonelela ngokutshaja ngokukhawuleza, ukusebenza okuphezulu, ixesha elide lokuphila, ukugcinwa kweqanda, ukhuseleko oluphezulu, kunye nefuthe eliphantsi kokusingqongileyo.
