Ki te noho koe i tētahi wāhi e tino kino ana te rangi, e motu ana rānei te hiko i ngā wā katoa, he mea pai kia whai pūtake hiko tārua mō tō kāinga. He maha ngā momo pūnaha hiko tārua kei te mākete, engari he kotahi te kaupapa matua o ia momo: te pupuri i ō rama me ō taputapu hiko kia mura tonu ina motu te hiko.

He tau pai pea tēnei hei tirotiro i te hiko tārua: He nui te tūponotanga o te motuhanga hiko i te nuinga o Amerika Te Raki i tēnei raumati nā te tauraki tonu, ā, e matapaetia ana he teitei ake i te pāmahana toharite, e ai ki te North American Electric Reliability Corporation i te Wenerei. Ko ētahi wāhanga o te Hononga o Amerika, mai i Michigan ki te Takutai Moana, kei te tino tūponotanga ka motuhanga te hiko.

I ngā wā o mua, ko ngā mīhini hiko tūmatanui e whakamahia ana te wahie (e mōhiotia ana ko ngā mīhini hiko whare katoa) te mea nui rawa atu i te mākete hiko tārua, engari kua ārahi ngā pūrongo mō te mōrearea o te paihana hauota waro ki te rapu huarahi kē atu. Kua puta ake ngā mīhini hiko tārua hei kōwhiringa pai ake mō te taiao, ā, he haumaru ake pea i ngā mīhini hiko tuku iho.

Ahakoa te mahi ōrite, he rerekē ngā taputapu tārua pākahiko me ngā taputapu whakaputa hiko. He huinga painga me ngā ngoikoretanga motuhake o ia taputapu, ka hipokina e mātou ēnei i roto i te aratohu whakatairite e whai ake nei. Pānuihia tonu kia mōhio ai koe ki ngā rerekētanga matua i waenga i ngā tārua pākahiko me ngā taputapu whakaputa hiko, ā, whakatauhia ko tēhea te kōwhiringa pai rawa atu māu.

Ngā tārua pākahiko
Ko ngā pūnaha tārua pākahiko kāinga, pērā i te Tesla Powerwall, te LG Chem RESU rānei, ka penapena i te hiko, ka taea e koe te whakamahi hei whakakaha i tō whare i te wā e motu ana te hiko. Ka whakamahia te hiko hei whakakaha i ngā pākahiko, mai i tō pūnaha rā kāinga, mai i te whatunga hiko rānei. Nō reira, he pai ake ēnei mō te taiao i ngā whakaputa hiko wahie. He pai ake hoki mō tō pēke moni.

Hei tāpiritanga, ki te mea he mahere ratonga wā-whakamahinga tāu, ka taea e koe te tono i tētahi pūnaha tārua pākahiko hei penapena moni i runga i ō pire hiko. Engari i te utu i ngā utu hiko teitei i ngā wā tino nui o te whakamahinga, ka taea e koe te whakamahi i te hiko mai i tō tārua pākahiko hei whakakaha i tō whare. I ngā wā kāore i te tino nui te whakamahinga, ka taea e koe te whakamahi i tō hiko hei mahi noa - engari i te utu iti ake.

I tētahi atu taha, ka hono ngā pūkaha hiko tūmatanui ki te papa hiko o tō whare, ā, ka tīmata aunoa ina motu te hiko. Ka whakamahia te wahie hei pupuri i te hiko kia mau tonu i te wā e motu ana te hiko — te nuinga o te wā he hau māori, he propane wai, he tīhiera rānei. He āhuatanga "wahie takirua" anō hoki ō ētahi atu pūkaha hiko, arā, ka taea te whakamahi i te hau māori, i te propane wai rānei.

Ka taea e ētahi miihini whakaputa hau māori me te propane te hono atu ki te raina hau, ki te tāke propane rānei o tō whare, nō reira kāore he take ki te whakakī ā-ringa. Heoi anō, me whakakī anō ngā miihini whakaputa hinu tīhiera kia taea ai te whakahaere tonu.

Pūhiko tārua me te pūhiko whakaputa hiko: He aha te whakataurite?
Utu
Mō te utu,ngā tārua pākahikokoinei te kōwhiringa utu nui ake i te tīmatanga. Engari me whakamahi te hinu i ngā miihini whakaputa hiko hei whakahaere, ko te tikanga ka nui ake te whakapaunga moni i roto i te wā hei pupuri i te putunga wahie pumau.

Mō ngā pūrua pākahiko, me utu wawe koe mō te pūnaha pākahiko pūrua, me ngā utu tāutanga (ia mano ngā utu). Ka rerekē ngā utu tika i runga i te tauira pākahiko e whiriwhiria e koe me te maha o aua mea e hiahiatia ana e koe hei whakakaha i tō whare. Heoi, he mea noa te whakahaere a te pūnaha pūrua pākahiko kāinga rahi toharite i waenga i te $10,000 me te $20,000.

Mō ngā mīhini whakaputa hiko, he iti ake ngā utu tīmatanga. I te toharite, ko te utu mō te hoko me te tāuta i tētahi mīhini whakaputa hiko tūmatanui ka rerekē mai i te $7,000 ki te $15,000. Heoi, kia mahara me whakamahi wahie ngā mīhini whakaputa hiko hei whakahaere, ā, ka piki ake ō whakapaunga whakahaere. Ka whakawhirinaki ngā utu motuhake ki ētahi āhuatanga, tae atu ki te rahi o tō mīhini whakaputa hiko, te momo wahie e whakamahia ana me te nui o te wahie e whakamahia ana hei whakahaere.

Tāutanga
He iti te painga o ngā pūhiko tārua i tēnei wāhanga nā te mea ka taea te whakairi ki te pakitara, ki te papa rānei, engari me mahi anō mō ​​te tāutanga o ngā whakaputa hiko. Ahakoa pēhea, me utu e koe he tohunga mō tētahi momo tāutanga, e rua ngā momo e hiahiatia ana he rā mahi katoa, ā, tera pea ka utua he mano tāra.

Haunga te whakatū i te taputapu, me riringi anō hoki he pereti raima ki te tāutanga o te mīhini whakaputa wahie, me te tāuta i tētahi pana whakawhiti.

Te tiaki
Ko ngā pūhiko tārua te toa mārama i tēnei wāhanga. He marino, he motuhake te whakahaere, kāore e whakaputa tukunga, ā, kāore e hiahiatia he tiaki tonu.

I tētahi atu taha, ka tino haruru, ka whakararuraru hoki ngā whakaputa hiko ina whakamahia ana. Ka tukuna hoki e rātou he hau, he paoa rānei, i runga i te momo wahie e whakamahia ana e rātou — ka riri pea koe, ō hoa noho tata rānei.

Te pupuri i te hiko o tō whare

Mō te roa o te wā e taea ai e ngā miihini hiko tūwhera te pupuri i te hiko o tō whare, he pai ake te pai o ngā pūhiko pūhiko e toe ana. Mēnā he nui te wahie kei a koe, ka taea e ngā miihini hiko te mahi tonu mō te toru wiki i te wā kotahi (mēnā e tika ana).

Kāore rawa tēnei e rite ki te pūrua pākahiko. Hei tauira, me whakamahi tātou i te Tesla Powerwall. He 13.5 kilowatt-haora tōna kaha rokiroki, ka taea te whakarato hiko mō ētahi haora anake. Ka taea e koe te whiwhi hiko tāpiri mai i a rātou mēnā he wāhanga o tētahi pūnaha panera rā, mēnā rānei ka whakamahia e koe he maha ngā pākahiko i roto i te pūnaha kotahi.

Te roanga o te ora e tumanakohia ana me te pūtāhui
I te nuinga o te wā, he roa ake ngā wā whakamana mō ngā pūtāhui pākahiko i ngā whakaputa hiko tūtatari. Heoi, he rerekē ngā huarahi e inehia ai ēnei pūtāhui.

I roto i te wā, ka ngaro te kaha o ngā pūnaha tārua pākahiko ki te pupuri i te utu, pērā i ngā waea me ngā pona. Nā reira, kei roto i ngā tārua pākahiko he whakatauranga kaha i te mutunga o te pūtāhui, e ine ana i te whai huatanga o te pākahiko ki te pupuri i te utu i te mutunga o tōna wā pūtāhui. Mō Tesla, ka oati te kamupene me pupuri e te pākahiko Powerwall te 70% o tōna kaha i te mutunga o tana pūtāhui 10-tau.

Ka tukuna hoki e ētahi kaihanga pākahiko tārua he pūtāhui "pūngao". Koinei te maha o ngā huringa, ngā hāora, te putanga pūngao rānei (e mōhiotia ana ko te "pūngao") ka whakamanahia e te kamupene ki tana pākahiko.

Mā ngā pūkaha hiko tūmatanui, he māmā ake te whakatau tata i te roa o te ora. Ka taea e ngā pūkaha hiko kounga pai te mahi mō ngā hāora 3,000, mena ka tiakina pai. Nō reira, ki te whakahaerehia e koe tō pūkaha hiko mō ngā hāora 150 ia tau, ka roa pea mō te 20 tau.

Ko tēhea te mea tika māu?
Mō te nuinga o ngā kāwai,pūrua pākahikoKo ngā pūnaha te mea pai rawa atu. I roto i te poto, he pai ake mō te taiao, he māmā ake te tāuta, ā, he iti ake te utu mō te whakahaere mō te wā roa. Hei tāpiri, he roa ake ā rātou pūtāhui i ngā whakaputa hiko tūmatanui.

Ahakoa rā, he pai pea ngā mīhini hiko tuku iho i ētahi wā. Kāore i rite ki ngā pūrua pākahiko, kotahi anake te mīhini hiko e hiahiatia ana hei whakaora i te hiko i te wā e motu ana te hiko, ā, ka whakaitihia ngā utu o mua. Hei tāpiri, ka roa ake te ora o ngā mīhini hiko tūmatanui i ngā pūnaha pūrua pākahiko i te wā kotahi. Nō reira, he pai ake mēnā ka motu te hiko mō ngā rā.
