Angakanani umthamo webhethri?
Umthamo webhethri inani leshaja kagesi elingalethwa ngamandla kagesi angehli ngaphansi kwetheminali eshiwo. Amandla avame ukushiwo ngamahora we-ampere (A·h) (mAh yamabhethri amancane). Ubudlelwano phakathi kwamanje, isikhathi sokukhipha kanye nomthamo kulinganiselwa (ngaphezu kwebanga elijwayelekile lamanani amanje)Umthetho kaPeukert:
t = Q/I
tinani lesikhathi (ngamahora) ibhethri elingasigcina.
Qamandla.
Ieyamanje ethathwe ebhethrini.
Isibonelo, uma ukukhanya kwelanga okunamandla ebhethri angu-7Ah kusetshenziswa no-0.35A wamanje, isikhathi sokusebenzisa singaba amahora angu-20. Futhi ngokusho kwe-Umthetho kaPeukert, singakwazi ukuthi uma tumthamo webhethri wokukhanya kwelanga uphakeme, ungasetshenziswa isikhathi eside. Futhi umthamo webhethri wochungechunge lwe-Liper D ukukhanya kwe-solar street kungafinyelela ku-80Ah!
I-Liper iqinisekisa kanjani umthamo webhethri?
Wonke amabhethri asetshenziswa emikhiqizweni ye-Liper akhiqizwa yithi. Futhi zihlolwa umshini wethu wochwepheshe esishaja ngawo futhi sikhiphe amabhethri izikhathi ezi-5. (Umshini ungasetshenziswa futhi ukuhlola impilo yesiyingi sebhethri)
Ngaphandle kwalokho, sisebenzisa i-lithium iron phosphate (LiFePO4) ubuchwepheshe bebhethri okufakazelwa ukuthi bungahlinzeka ngokushaja okushesha kakhulu kanye nokulethwa kwamandla, kukhiphe wonke amandla awo emlayishweni ngemizuzwana eyi-10 ukuya kwengama-20 esivivinyweni sango-2009. Uma kuqhathaniswa nezinye izinhlobo zamabhethri,Ibhethri le-LFP liphephe kakhudlwana futhi liphila isikhathi eside.
Kuyini ukusebenza kahle kwephaneli yelanga?
Iphaneli yelanga iyisisetshenziswa esiguqula ukukhanya kwelanga kube ugesi ngokusebenzisa amaseli e-photovoltaic (PV). Futhi ukusebenza kahle kwephaneli yeSolar yingxenye yamandla ngendlela yokukhanya kwelanga engaguqulwa nge-photovoltaics ibe ugesi ngeseli yelanga.
Ngemikhiqizo yelanga ye-Liper, sisebenzisa iphaneli yelanga ye-mono-crystalline silicon. Ngokusebenza okurekhodiwe kwelebhu ye-single junction cell26.7%, i-silicon ye-mono-crystalline inokuguqulwa okuqinisekisiwe okuphezulu kakhulu kubo bonke ubuchwepheshe be-PV yezentengiso, ngaphambi kwe-poly-Si (22.3%) kanye nobuchwepheshe obusungulwe befilimu emincane, njengamaseli e-CIGS (21.7%), amaseli e-CdTe (21.0%) , kanye namaseli e-a-Si (10.2%). Ukusebenza kwemojula yelanga ye-mono-Si—ehlala iphansi kunaleyo yamaseli ahambisanayo—ekugcineni kweqe uphawu lwama-20% ngo-2012 futhi yashaya u-24.4% ngo-2016.
Kafushane, ungagxili nje emandleni lapho ufuna ukuthenga imikhiqizo yelanga! Naka umthamo webhethri nokusebenza kahle kwephaneli yelanga! I-Liper ikhiqiza imikhiqizo yelanga engcono kakhulu kuwe ngaso sonke isikhathi.
