Amasistimu okukhiqiza amandla e-off-grid photovoltaic asetshenziswa kakhulu ezindaweni ezikude ezisezintabeni, ezindaweni ezingezona ugesi, iziqhingi, iziteshi eziyisisekelo zokuxhumana kanye nezibani zasemgwaqweni. I-photovoltaic array iguqula amandla elanga abe amandla kagesi ngaphansi kwesimo sokukhanya, futhi inikeze amandla kumthwalo ngokusebenzisai-solar charge kanye nesilawuli sokukhipha, futhi ishaje iphakethe lebhethri ngesikhathi esifanayo; uma kungenakukhanya, iphakethe lebhethri linikeza amandla kumthwalo we-DC ngokusebenzisa isilawuli sokushaja solar kanye nokukhipha. Ngesikhathi esifanayo, ibhethri iphinde inikeze amandla ngokuqondile ku-inverter ezimele, eguqulwa ibe i-alternating current ngokusebenzisa i-inverter ezimele ukuze inikeze amandla kumthwalo wamanje oshintshanayo.
Ukwakhiwa Kwesistimu Yelanga
(1) IlangaIbhethri Module
I-solar cell module iyingxenye eyinhloko yeuhlelo lokuphakela amandla elanga, futhi liphinde libe ingxenye ebaluleke kakhulu ohlelweni lokuphakelwa kwamandla elanga. Umsebenzi wawo ukuguqula amandla emisebe yelanga abe ugesi wamanje oqondile.
(2) Isilawuli Solar
I-solar charge and discharge isilawuli sibizwa nangokuthi "isilawuli se-photovoltaic". Umsebenzi wayo ukulungisa nokulawula amandla kagesi akhiqizwa imojula yeseli yelanga, ukushaja ibhethri ngezinga eliphezulu, nokuvikela ibhethri ekukhokhisweni ngokweqile nasekukhishweni ngokweqile. umphumela. Ezindaweni ezinomehluko omkhulu wokushisa, isilawuli se-photovoltaic kufanele sibe nomsebenzi wokunxeshezelwa kwezinga lokushisa.
(3) I-Off-grid Inverter
I-off-grid inverter iyingxenye eyinhloko yesistimu yokuphehla amandla e-off-grid, enesibopho sokuguqula amandla e-DC abe amandla e-AC ukuze asetshenziswe imithwalo ye-AC. Ukuze uthuthukise ukusebenza okuphelele kwesistimu yokukhiqiza amandla e-photovoltaic futhi uqinisekise ukusebenza okuzinzile kwesikhathi eside kwesiteshi samandla, izinkomba zokusebenza ze-inverter zibaluleke kakhulu.
(4) Iphakethe Lebhethri
Ibhethri isetshenziselwa kakhulu ukugcina amandla ukuze inikeze amandla kagesi ekulayisheni ebusuku noma ezinsukwini zemvula. Ibhethri liyingxenye ebalulekile yesistimu ye-off-grid, futhi izinzuzo nezingozi zayo zihlobene ngokuqondile nokuthembeka kwalo lonke uhlelo. Nokho, ibhethri iyidivayisi enesilinganiso sesikhathi esifushane phakathi kokuhluleka (MTBF) kulo lonke uhlelo. Uma umsebenzisi engayisebenzisa futhi ayigcine ngokujwayelekile, impilo yayo yesevisi inganwetshwa. Uma kungenjalo, impilo yayo yesevisi izofinyezwa kakhulu. Izinhlobo zamabhethri ngokuvamile amabhethri aneasidi yomthofu, amabhethri angenayo i-lead-acid-free kanye namabhethri e-nickel-cadmium. Izici zabo ezihlukene zikhonjisiwe kulelithebula elingezansi.
| isigaba | Uhlolojikelele | Izinzuzo kanye nokubi |
| Ibhethri ye-lead acid | 1. Kujwayelekile ukuthi amabhethri ashajwe omile agcinwe ngokungeza amanzi ngesikhathi sokusetshenziswa. 2. Impilo yesevisi ingu-1 kuya kwemi-3. | 1. I-Hydrogen izokhiqizwa ngesikhathi sokushaja nokukhipha, futhi indawo yokubeka kufanele ifakwe ipayipi lokukhipha umoya ukuze kugwenywe ukulimala. 2. I-electrolyte ine-asidi futhi izogqwalisa izinsimbi. 3. Ukugcinwa kwamanzi njalo kuyadingeka. 4. Inani eliphezulu lokugaywa kabusha |
| Amabhethri e-lead-asidi angalondolozi | 1. Okuvame ukusetshenziswa amabhethri ejeli avaliwe noma amabhethri omjikelezo ojulile 2. Asikho isidingo sokwengeza amanzi ngesikhathi sokusetshenziswa 3. Ukuphila iminyaka emi-3 kuya kwemi-5 | 1. Uhlobo oluvaliwe, ayikho igesi eyingozi ezokhiqizwa ngesikhathi sokushaja 2. Kulula ukusetha, asikho isidingo sokucabangela inkinga yokungena komoya yendawo yokubeka 3. Akunasondlo, akunasondlo 4. Izinga eliphezulu lokukhipha kanye nezici ezizinzile 5. Inani eliphezulu lokugaywa kabusha |
| Ibhethri ye-Lithium ion | Ibhethri elisebenza kahle kakhulu, asikho isidingo sokwengeza Ukuphila kwamanzi iminyaka eyi-10 kuya kwengama-20 | Ukuqina okuqinile, ukushaja okuphezulu nezikhathi zokukhishwa, usayizi omncane, isisindo esilula, kubiza kakhulu |
Izingxenye zesistimu ye-solar off-grid
Amasistimu e-photovoltaic angaphandle kwegridi ngokuvamile akhiwa ama-photovoltaic arrays akhiwe izingxenye zamaseli elanga, izilawuli zokushajwa kwelanga nezikhiphayo, amaphakethe ebhethri, iziguquli ze-off-grid, imithwalo ye-DC nemithwalo ye-AC.
Izinzuzo:
1. Amandla elanga awapheli futhi awapheli. Imisebe yelanga etholwe ebusweni bomhlaba ingahlangabezana nesidingo samandla esiphindwe izikhathi ezingu-10,000 emhlabeni wonke. Uma nje izinhlelo ze-solar photovoltaic zifakiwe ku-4% wezingwadule zomhlaba, ugesi okhiqizwayo ungahlangabezana nezidingo zomhlaba. Ukukhiqizwa kwamandla elanga kuphephile futhi kuthembekile, futhi ngeke kuhlupheke ngenxa yezinkinga zamandla noma ukungazinzi kwemakethe kaphethiloli;
2. Amandla elanga atholakala yonke indawo, futhi anganikeza amandla eduze, ngaphandle kokudluliselwa kwebanga elide, ukugwema ukulahlekelwa izintambo zokudlulisela amabanga amade;
3. Amandla elanga awadingi uphethiloli, futhi izindleko zokusebenza ziphansi kakhulu;
4. Azikho izingxenye ezihambayo zokukhiqiza amandla elanga, akulula ukonakala, futhi ukugcinwa kulula, ikakhulukazi kulungele ukusetshenziswa okunganakiwe;
5. Ukuphehlwa kwamandla elanga ngeke kukhiphe imfucuza, akukho kungcola, umsindo nezinye izingozi zomphakathi, akunamthelela omubi endaweni ezungezile, kungamandla ahlanzekile afanelekile;
6. Isikhathi sokwakhiwa kwesistimu yokukhiqiza amandla elanga sifushane, silula futhi siyavumelana nezimo, futhi ngokusho kokwanda noma ukuncipha komthwalo, inani lamandla elanga lingangezwa noma lincishiswe ngokuzenzakalelayo ukuze kugwenywe ukumosha.
Ububi:
1. Ukusetshenziswa komhlabathi kuyahamba kancane futhi akuhleliwe, futhi ukukhiqizwa kwamandla kuhlobene nezimo zezulu. Ayikwazi noma ayivamile ukukhiqiza amandla ebusuku noma ngezinsuku ezinamafu nezimvula;
2. Ukuminyana kwamandla kuphansi. Ngaphansi kwezimo ezijwayelekile, amandla emisebe yelanga atholwe phansi ngu-1000W/M^2. Uma isetshenziswa ngosayizi omkhulu, idinga ukuthatha indawo enkulu;
3. Intengo isabiza kakhulu, futhi ukutshalwa kwezimali kokuqala kuphezulu.
