He maha ngā kaihoko ka pātai, "Kia pēhea te rahi o te pākahiko e hiahiatia ana mō te pūngao rā?"ina whiriwhiri ana i tētahi mea e tika anapākahiko nui 48Vmō ō rātou kāinga nunui. Mō ngā kāinga hou, hepākahiko rā nuiKo te awhe 10-20 kWh te whiringa pai rawa atu hei whakanui ake i te mana motuhake me te mana tārua. Nā ngā whanaketanga o te hangarau pākahiko lithium kua nui ake ngā kaha, pērā i te 15 kWh, 20 kWh rānei, e wātea ana, e whai hua ana hoki. Kei raro nei, ka whakamāramahia me pēhea te whiriwhiri i te rahi tika mō ō hiahia.
1. Pūhiko Nui mō te Kāinga: Te Whakahāngai i te Pūngao ki ngā Hiahia Pūngao
E whakamahi ana te whare toharite o Amerika i te 25-35 kWh ia rā, ā, ka taea e tētahi pākahiko nui mō ngā panera rā (10-20 kWh) te pupuri i te 30-60% o tēnei hiahia.
Hei tauira, hepēke pākahiko rā nui (15 kWh)Ka whakakaha i ngā mea nui pēnei i ngā pouaka whakamātao, ngā rama, me te Wi-Fi mō ngā haora 18-24. Mena ko tāu whāinga he motuhake i te hiko, tīmata ki tētahi pūnaha hiko pūngao nui i te pito iti (10-12 kWh).
Mō ngā kaiwhakamahi taumaha, mō ngā kaipupuri waka hiko rānei, whakanekehia ake ki te 20 kWh hei utu mō te nui ake o te whakamahinga hiko.
2. Ngā Pūhiko Nui mō te Rā: Te Whakataurite i te Mana Tārua me te Manawanui ki te Motuka
Ka piki ake te uara o te pākahiko rā nui i te wā e motu ana te hiko.Pūhiko 20 kWhka taea te pupuri i te kawenga 2,000W (hei tauira, HVAC me te pouaka whakamātao) mō ngā hāora 10, i te iti rawa rānei o te kawenga 500W mō ngā hāora 40+.
Mā te hono i ngā pākahiko nui mō te pūngao rā me ngā panera ka taea te whakahou i te awatea, ka whakaiti i te whakawhirinaki ki tepākahiko rā nui rawa atu(30+ kWh) ki te kore koe e whakamahi i te whatunga hiko. Whakaritea ngā ara iahiko matua (ngā taputapu hauora, ngā pūnaha haumarutanga) hei ārai i te whakapaunga nui ki te kaha kore e hiahiatia.
3. Ngā Pūnaha Pūhiko Nui o te Rā: Hangarau, Hototahi, me te Ārai i te Ao Tūroa
Houngā pākahiko rā nui lithium-ion(hei tauira,Pūhiko YouthPOWER) e tuku ana i te hōhonutanga o te tukunga 100% me te roa o te oranga mō ngā tau 10+, e whai hua ai ngā waeine 10-20 kWh hei haumitanga mō te wā roa.
Kia tino rite te rahi o tō pākahiko nui ki tō pūnaha rā: Ka taea e te pūnaha 8-10 kW te whakaputa i te 30-40 kWh ia rā, ka taea te utu ngāwari i tePūhiko pūhiko rā nui 20 kWhHei whakanui ake i te whai huatanga, karohia te whakamahi i te rahi rawa atu i tua atu i tāu whakaputanga pūngao rā. Ka taea e te nui rawa o te utu te whakaiti i te whai huatanga.
Taunakitanga Whakamutunga
Ka taea e te pākahiko rā nui 10-20 kWh te whakataurite i te whakamahinga o ia rā, ngā hiahia tāpiri, me te utu. Tīmata ki te 15 kWh mō te nuinga o ngā kāinga, ā, whakawhānui atu ki ngā pākahiko nui mō ngā panera rā mēnā e tika ana.
Ngā taputapu pērā ite Tātaitai NREL PVWattska taea te whakapai ake i tō tatūnga—kāore he take ki te whakapau moni ki te pākahiko rā nui rawa atu mēnā kāore e tino hiahiatia.
