Ntuziaka zuru oke maka imepụta na nhazi sistemu PV-nchekwa ebe obibi

Sistemụ nchekwa fotovoltaic obibi (PV) bụ isi nwere modul PV, batrị nchekwa ike, ihe ntụgharị nchekwa, ngwaọrụ metering, na sistemụ njikwa nlekota. Ebumnobi ya bụ iji nweta ikike nke onwe, ibelata ụgwọ ọrụ ume, mbelata ikuku carbon, yana melite ntụkwasị obi ike. Ịhazi usoro nchekwa PV-bibi bụ usoro zuru oke nke chọrọ nlezianya tụlee ihe dị iche iche iji hụ na arụ ọrụ nke ọma na nke kwụsiri ike.

I. Nchịkọta nke Sistemụ Nchekwa PV-Residential

Tupu ịmalite ntọlite ​​​​usoro, ọ dị mkpa ịlele nguzogide mkpuchi DC n'etiti ntinye ntinye PV array na ala. Ọ bụrụ na nguzogide ahụ na-erughị U…/30mA (U… na-anọchi anya voltaji mmepụta kachasị nke PV array), a ga-emerịrị usoro mgbada ma ọ bụ mkpuchi ọzọ.

Ọrụ ndị bụ isi nke sistemu nchekwa PV ebe obibi gụnyere:

• Iri onwe ya: Iji ike anyanwụ na-egbo mkpa ike ezinụlọ.
• Ịkpụcha ọnụ ọnụ na imeju ndagwurugwu: Ịhazi ojiji ike gafee oge dị iche iche iji chekwaa ego ọkụ.
• Ike ndabere: Inye ike a pụrụ ịdabere na ya n'oge nkwụsị.
• Ọkụ ọkụ mberede: Na-akwado ibu dị oke egwu n'oge ọdịda grid.

Usoro nhazi ahụ gụnyere nyochaa mkpa ike onye ọrụ, ịmepụta PV na usoro nchekwa, ịhọrọ ihe ndị dị na ya, na-akwadebe atụmatụ nrụnye, na ịkọwapụta ọrụ na nhazi.

II. Nleba anya na nhazi ihe achọrọ

Nyocha Achọ Ike

Nleba anya ike zuru oke dị oke mkpa, gụnyere:

• Ibu profaịlụ: Ịmata ike chọrọ nke ngwa dị iche iche.
• Oriri kwa ụbọchị: Ịchọpụta nkezi ọkụ eletrik n'oge ehihie na abalị.
• Ọnụ ahịa ọkụ eletrik: Ịghọta usoro tarifu iji kwalite usoro maka nchekwa ego.

Ọmụmụ ihe

• Profaịlụ onye ọrụ:
  • Mkpokọta ibu ejikọrọ: 8.2 kW
  • Ibu dị mkpa: 3.6 kW
  • Oriri ike nke ụbọchị: 10 kWh
  • Oriri ike abalị: 20 kWh
• Atụmatụ Sistemu:
  • Wụnye sistemu ngwakọ nchekwa PV nwere ọgbọ PV ụbọchị na-egbo mkpa ibu na-echekwa oke ike na batrị maka ojiji abalị. Grid na-arụ ọrụ dị ka isi iyi ike agbakwunyere mgbe PV na nchekwa ezughị oke.
