Kua kite pea koe i te kupu nei e whakamahia whānuitia ana i roto i ngā rarangi hua me ngā whakaaturanga hokohoko. Engari he aha rawa te kete pūngao rā, ā, he aha te take e hiranga ai ki tō pakihi?
Anei te whakautu poto: hekete pūngao rāhe pūnaha kua oti te tākai, kei roto ko ngā mea katoa e hiahiatia ana e koe hei whakaputa hiko o te rā—ngā panera, te kaiwhakahaere utu, te inverter, ngā pākahiko, ngā taura, me ngā taputapu whakairi. Kotahi te pouaka. Kotahi te ota hoko. Kāore he whai i ngā wāhanga mai i ngā kaiwhakarato rerekē e rima.
He māmā noa iho te tangi, tika? Ae. Ā, koinei tonu te take i noho ai ngā kete hiko pūngao rā hei otinga matua mā ngā kaituku, ngā kaimahi kirimana, me ngā kaiwhakawhanake kaupapa e hiahia ana ki ngā pūnaha pono, me te kore e rapu raruraru ki te kimi rauemi.
He aha ngā mea kei roto i tētahi kete pūngao rā noa?
Ehara i te mea he ōrite katoa ngā kete, engari ko te nuinga kei roto ko ēnei wāhanga matua:
Ngā Paewhiri Rā– Te pūtake hiko. Ko ngā panera monocrystalline te mea nui rawa atu i te mākete mō tō rātou whai huatanga (18-22%), ahakoa kei te kitea ngā kōwhiringa polycrystalline i roto i ngā kete e aro ana ki te tahua iti.
Kaiwhakahaere Utu– Ka tiaki i ō pākahiko mai i te utu nui rawa. He pai te mahi a ngā pūmana PWM mō ngā pūnaha iti ake. He nui ake te utu o ngā pūmana MPPT engari ka piki ake te pai o te mahi a ō panera mā te 15-30%.
Kaitahuri– Ka huri i te mana DC ki te mana AC. He pai ake te whakahaere a ngā kaitahuri ngaru sine parakore i ngā hiko tairongo i ngā waeine ngaru sine kua whakarerekētia. He mea nui te rahi i konei—ka puta he arai i ngā kaitahuri iti.
Pēke Pūhiko– Ka rongoa i te pūngao mō ngā rā pō, ngā rā kapua rānei. Ka roa ake te ora o ngā pākahiko lithium-ion (LiFePO4) ā, ka roa ake te huringa tukunga i ērā o te waikawa mata. Engari ka rua, ka toru rānei ngā wā ka nui ake te utu i te tīmatanga.
Ngā Taura me ngā Hononga– He paerewa ā-umanga ngā hononga MC4. Kaua e wareware ki te ine taura—ko te iti o te rahi o ngā waea ka heke te ngaohiko me te maumau hiko.
Ngā taputapu whakairi– Ngā whakairinga tuanui, ngā whakairinga whenua, ngā whakairinga pou. Kei te whakamahinga.
E toru ngā momo kete pūngao rā ka tūtaki koe
Ngā Kete Pūngao Rā i Waho i te Whatunga
Kāore he hononga ratonga. Ka rere motuhake te pūnaha—ka utua e ngā panera ngā pākahiko i te awatea, ka whakakahangia ngā uta e ngā pākahiko i te pō. He rongonui mō ngā mahi hiko taiwhenua, ngā kāpata, ngā pourewa waea, me ngā teihana aroturuki mamao.
He mea nui te rahi i konei. Mēnā ka whakaitihia te rahi e hiahiatia ana, ka hē te pūnaha i te wā e tino hiahiatia ana e ngā kaiwhakamahi.
Ngā Kete Pūngao Rā e Herea ana ki te Whatunga
Ka hono tika ēnei ki te whatunga hiko. Ka whakahokia te hiko nui ki te whatunga hiko; ka tangohia mai i te whatunga ngā hapa. Kāore e hiahiatia he pākahiko i te nuinga o ngā whirihoranga, ā, ka tino whakaitihia ngā utu.
Ko te raruraru? Ina mate te whatunga hiko, ka mate anō hoki tō pūnaha—ki te kore koe e tāpiri i tētahi pūhiko tārua.
Ngā Kete Pūngao Rā Ranu
Ko te mea pai rawa atu o ngā ao e rua. He hononga whatunga me te rokiroki pākahiko. Ka whakatairangahia e te pūnaha te hiko o te rā, ka rongoa te toenga ki roto i ngā pākahiko, ā, ka tangohia noa mai i te whatunga ina hiahiatia. He nui ake te utu o mua, engari ko te mana motuhake me te hiko tārua e whai hua ana mō ngā tono arumoni.
He aha ngā kaihoko e neke atu ana ki ngā kete pūngao rā katoa
Kia pono tātou—he uaua te kimi i ngā wāhanga takitahi. Kei te whiriwhiri koe i ngā kaiwhakarato maha, kei te whakataurite i ngā whakaritenga, kei te whakahaere i ngā wā tuku motuhake, me te tumanako ka mahi tahi ngā mea katoa ina tae mai.
Ka whakakorea e ngā kete pūngao rā taua waku. Kua whakaritea ngā wāhanga kia hototahi. Kotahi te kaiwhakarato e whakahaere ana i te mana kounga. Kotahi te nama. Kotahi te wāhi whakapā ina he te mea.
Mō ngā kaiwhakarato e hanga ana i ngā taonga, ka māmā ake te whakahaere i ngā SKU. Mō ngā kaimahi kirimana, ka whakaitihia ngā hapa tāutanga. Mō ngā kaiwhakamahi mutunga, ko te tikanga he tere ake te whakatinanatanga me te iti ake o ngā ohorere.
Ngā mea hei tirotiro i mua i tō tono
He pātai torutoru hei pātai atu ki tō kaiwhakarato:
Ngā waitohu wāhanga– Nō ngā kaihanga rongonui ngā panera, ngā kaitahuri, me ngā pākahiko, he wāhanga whānui rānei kāore i te mōhiotia?
Te kapinga pūtāhui– E kapi ana te pūtāhui kete i ngā wāhanga katoa, i ētahi noa iho rānei? Mā wai e whakahaere ngā kereme?
Ngā Tiwhikete– IEC, TUV, CE, UL—he mea nui te hanganga ture, kei runga i te mākete e hiahiatia ana e koe.
Whakawhanuitanga– Ka taea e te pūnaha te whakanui ake i muri mai, kāore rānei he ara mutunga?
Ngā tuhinga– Ngā hoahoa waea, ngā aratohu tāutanga, ngā pepa whakaritenga. Ka miharo koe ki te maha o ngā kaiwhakarato e karo ana i tēnei.
Kei te rapu koe i tētahi Kaiwhakarato Kete Pūngao Rā Pono?
We te hanga me te tuku i ngā kete pūngao rā katoamō ngā tono kore-whatunga, here-whatunga, me ngā tono ranu—mai i ngā pūnaha noho 1kW ki ngā tāutanga arumoni 50kW+. Ngā whirihoranga ngāwari. Kei te wātea ngā tapanga tūmataiti. Utu ipu whakataetae me te tuku ki ngā tauranga puta noa i te ao.
Kōrerotia mai ngā āhuatanga o tō kaupapa. Mā mātou e whakarite he whakatau utu e tika ana mō tō mākete.
