I te wa e whakangao ana koe ki te punaha hiko solar, ko tetahi o nga whakatau nui ka pa ki a koe ko te whiriwhiri i te pākahiko tika. Ma te pākahiko ka taea e koe te penapena i te hiko i hangaia e o panui solar, ka taea e koe te whakamahi i nga ra kapua, i te po ranei. Engari me pehea e whakatau ai koe i te rahi o te pākahiko mo to punaha solar? I roto i tenei aratohu, ka awhina matou ki a koe ki te whakatau i te rahi o te pākahiko pai mo koe 10kW pūnaha solar.
Kia mohio koe ki te whakaputanga Pungao o to punaha solar ia ra
Ko te mahi tuatahi ki te whakatau i te rahi o to pākahiko ko te whakatau tata i te nui o to kaha 10kW pūnaha solar whakaputa ia ra. He rereke te kaha o nga punaha solar i runga i nga ahuatanga penei i te waahi, te huarere, me te maha o nga haora ra e waatea ana ia ra.
I te toharite, a 10kW pūnaha solar ka taea te whakaputa 40-50 kWh o te hiko ia ra. Ko tenei tataunga e 5 haora te ra o te ra ia ra, he tikanga mo nga rohe maha.
Hei tauira, mena ka 5 haora te ra o to punaha i te ra:
Panui tūtohutia: E hia te kaha ka taea e te punaha solar 10kw te whakaputa?
Kia pehea te nui o te Pungao e hiahia ana koe ki te penapena?
I muri mai, whakatauhia te nui o te kaha e hiahia ana koe ki te penapena mo te whakamahi a muri ake. Ka whakawhirinaki tenei ki te nui o te mana taapiri e hiahiatia ana e koe.
- Te rokiroki taketake mo te whakamahi i te po: Mena kei te pirangi koe ki te penapena i te kaha ki te kapi i to kai i te po (12 haora), me tino penapena koe 25KWh (hawhe o te reanga o ia ra).
- Pūrua rā katoa: Mēnā kei te pirangi koe ki te penapena pūngao kia mau i te rā katoa (50kWh), ka hiahia koe ki te pākahiko nui ake.
Mo te kainga noa, 25-50kWh o te rokiroki he pai.
Whakatauhia te Ngaohiko me te Pai o te Pūhiko
He maha nga momo ngaohiko ka tae mai nga pākahiko, me taurite te peeke pākahiko o to punaha solar ki te ngaohiko o to kaihurihuri. He ngaohiko pūnaha noa mo te rokiroki solar noho ko 48V. Mo tenei tauira, ka whakamahia e matou 48V nga pākahiko, na te mea ko te mea tino rongonui.
I tua atu, kua ngaro te pai o nga pākahiko. I te wa e utu ana koe me te tuku i te pākahiko, karekau te katoa o te kaha penapena e waatea ana hei whakamahi. Kei te tata te nuinga o nga pākahiko lithium-ion hou 80-90% pai, ko te tikanga me nui ake te rokiroki hei utu mo aua mate. Hei tauira, ki te hiahia koe 50kWh o te kaha whakamahia, ka hiahia pea koe he 60kWh pākahiko ki te whakatika mo te ngaronga whai hua.
Tātaihia te Raukaha Pūhiko e hiahiatia ana i roto i te Amp-Haora (Ah)
Inaianei kei a koe te whakaaro mo te nui o te kaha hei penapena, ka taea e koe te tatau i nga mea e hiahiatia ana kaha pūhiko i roto i te Amp-haora (Ah).
Anei te tātai:
Tauira mo te rokiroki 25kWh:
Raukaha Pūhiko (Ah)=25kWh × 1000 ÷ 48V=520.83AhTauira mo te rokiroki 50kWh:
Raukaha Pūhiko (Ah)=50kWh×1000 ÷ 48V=1041.67AhWhakaarohia te Hohonutanga o te Tukunga (DoD)
Ko te nuinga o nga pākahiko hou, ina koa ko te lithium-ion, he a Te Hohonu o te Tukunga (DoD) Tuhinga o mua 80-90%. Ko te tikanga ka hangaia te pākahiko kia whakamahia noa ki te 80-90% o tona kaha katoa ki te aukati i te kino me te whakanui ake i te oranga.
Ki te kaute mo te DoD, mena ka hiahia koe 50kWh o te rokiroki ka taea, ka hiahia koe he 60kWh pākahiko (ki te kaute mo te 20% o te kaha kaore i whakamahia).
Mo te 25kWh rokiroki taea, ka hiahia koe:
Rahi Pūhiko e hiahiatia ana (Ah)=(25kWh × 1000) ÷ (48V×0.8)=651.04AhTe Whakamutunga: Te Kowhiri i te Pūhiko Tika mo To 10kW Pūnaha Solar
Mo te 10kW pūnaha solar, ko te rahi o te pākahiko e hiahia ana koe ka whakawhirinaki ki te nui o te kaha e hiahia ana koe ki te penapena me te roa. Anei te wehenga tere o te kaha o te pākahiko e hiahiatia ana:
- Rokiroki taketake (25kWh): Me a 520Ah-650Ah 48V peeke pākahiko (i runga i te DoD).
- Rokiroki mo te ra katoa (50kWh): Me a 1040Ah-1300Ah 48V peeke pākahiko.
Hei whakarite kei te whiriwhiri koe i te pākahiko tika, whakaarohia o hiahia kaha me to taumata e hiahiatia ana mo te taapiri. Me mohio koe ki te kowhiri i te pākahiko e tika ana te kaha me te kaha ki te whakarato hiko pono ina kore to punaha solar e whakaputa.
Hei whakanui ake i te pai me te pono o to punaha hiko solar, whakaarohia te whakauru i te kounga teitei rokiroki pūngao kāinga soriwa. E rua nga whiringa whakamīharo e tukuna ana e ta maatau Pupuri Puohiko Puo-Matiti Hou Katoa-i-kotahi: 14.3KWh a 28.6KWh kaha. I hoahoatia enei pākahiko ki te penapena i te taikaha o te hiko i hangaia e o panui solar, kia mau tonu te toha hiko ahakoa i te po, i nga ra kapua. Na nga ahuatanga matatau me nga mahi pai ake, ko o maatau pākahiko katoa-i-kotahi ka whakarato i te otinga rokiroki hiko mo to kaainga.
Na roto i te haumi i roto i to tatou Pūhiko Pūhiko Katoa-i-kotahi kua Tāpaehia ki waho mātiti, ka taea e koe te whakarei ake i te mahi o to punaha hiko solar me te whakatutuki i te mana motuhake.
