I te haere tonu o te ao ki ngā otinga pūngao ma, pumau hoki, kua piki haere te rongonui o te hiko o te rā mō ngā kaipupuri whare me ngā pakihi. Ahakoa kei te whakaaro koe ki te tāuta i te hiko o te rā mō tō whare, kei te rapu rānei koe ki te whakakaha i tētahi whare arumoni, he mea nui te mārama ki ngā wāhanga matua o te pūnaha hiko o te rā hei whakatau whai whakaaro.
I roto i tēnei tuhinga, ka wetewetehia e mātou ngā wāhanga matua o tētahi pūnaha hiko o te rā, ka whakamāramahia te mahi tahi a ēnei wāhanga, ā, ka āwhina i a koe kia mārama ki ngā mea hei tumanakohia ina tāutahia he pūnaha hiko o te rā.
1. Ngā Paewhiri Rā
Kei te ngākau o ia pūnaha hiko o te rā ko tepapa rāKo ngā panera rā, e mōhiotia ana ko ngā kōwae photovoltaic (PV), ko rātou te kawenga mō te hopu i te rā me te huri hei hiko. He mea hanga ēnei mai i ngā pūtau silicon, e mimiti ana i te rā me te whakaputa hiko iahiko tika (DC).
He rerekē ngā momo o ngā panera rā, ko te mea tino noa ko ngā panera monocrystalline, polycrystalline, me ngā panera angiangi. He rerekē ngā painga o ia momo e pā ana ki te whai huatanga, te utu, me ngā whakaritenga tāutanga. Hei tauira, e mōhiotia ana ngā panera monocrystalline mō tō rātou whai huatanga nui me te roa o te ora, ko ngā panera angiangi ia he iti ake te whai huatanga engari he iti ake te utu.
2. Pūwhakahuri
Kia hurihia te hihi o te rā e ngā panera rā hei hiko DC, me huri hei hiko aukume rerekē (AC), koinei te momo hiko e whakamahia ana i te nuinga o ngā kāinga me ngā pakihi. Koinei te wāhi ewhakawhitika tomo mai.
He mea nui te inverter i roto i tētahi pūnaha hiko o te rā, nā te mea ka hurihia te hiko DC e whakaputaina ana e ngā panera ki te hiko AC. He maha ngā momo inverter, tae atu ki:
- Ngā kaitahuri ahoKoinei ngā momo e tino kitea ana, ā, e whakamahia whānuitia ana i roto i ngā pūnaha hiko o te rā i ngā kāinga. E honoa ana ēnei ki tētahi rārangi o ngā panera rā, ā, ka whāngaihia ngā panera katoa ki tētahi kaitahuri kotahi.
- Ngā kaitahuri itiHe iti ake ēnei ngā kaitahuri hiko e tāutahia ana ki ia panera rā. Ka taea e rātou te huri i te pūngao kia pai ake te whai hua, ā, ka taea hoki te āwhina i te whakapai ake i te mahi a te pūnaha, inā koa mēnā he atarangi ētahi panera, he rerekē rānei te koki o te whakanoho.
- Ngā kaiwhakapai manaKa mahi tahi ēnei taputapu me ngā kaitahuri aho, ā, ka āwhina i te whakanui ake i te putanga pūngao o ia panera, he rite tonu ki ngā kaitahuri moroiti, engari he iti ake te utu.
3. Rokiroki Pūhiko(Whiringa)
Ahakoa ka whakaputa hiko ngā pūnaha hiko o te rā i te awatea e whiti ana te rā, he aha te mea ka tupu ina tō te rā, ina kapua rānei? Koinei te wāhirokiroki pākahikoka whai wāhi mai. Mā te tāuta i ngā pākahiko, ka taea e koe te penapena i te hiko nui i hangaia i te awatea hei whakamahi ā muri ake nei ina kore te rā e whiti.
He tino whai hua ngā pūnaha rokiroki pākahiko mō ngā kāinga kāore e whakamahi i te whatunga hiko, ngā wāhi kāore e taea te uru atu ki te whatunga hiko, me te hunga rānei e hiahia ana ki te whakanui ake i tō rātou mana motuhake ki te hiko. Ko ngā kōwhiringa rokiroki pākahiko rongonui mō ngā pūnaha pūngao rā ko ngā pākahiko lithium-ion, he iti, he whai hua hoki, me ngā pākahiko waikawa-mata tuku iho.
4. Kaiwhakahaere Utu(Mō ngā Pūnaha Ā-Whatunga)
I roto i ngā pūnaha hiko pūngao rā i waho o te whatunga, hekaiwhakahaere utuhe mea tika hei whakahaere i te rere o te hiko mai i ngā panera rā ki ngā pākahiko. Mā tēnei taputapu ka tika te utu o ngā pākahiko, me te kore e nui rawa te utu, ka taea te whakapoto i te roa o te ora. Ka ārai hoki i te nui rawa o te tukunga o te hiko o ngā pākahiko, ka taea ai te kino.
Mō ngā pūnaha here-pūnaha (ina honoa te pūnaha hiko o te rā ki te pūnahi hiko), kāore e hiahiatia he kaiwhakahaere utu, nā te mea ka whakahaerehia e te pūnahi te hiko taikaha, ā, ka taea e koe te utu hiko ina hiahiatia.
5. Pūnaha Whakamau
Tepūnaha whakairihei whakau i ngā panera rā ki tōna tūranga, i runga i te tuanui o tō whare, i runga rānei i te whenua. Me pakari ēnei pūnaha, ā, me ātete hoki ki te huarere, nā te mea me ātete ki ngā āhuatanga taiao rerekē pēnei i te hau nui, te hukarere, me te ua.
He maha ngā momo whirihoranga o ngā pūnaha whakairi, pērā i ngā whata e whakairihia ana ki te tuanui, ngā hanganga rānei e whakairihia ana ki te whenua. Ko ngā pūnaha e whakairihia ana ki te tuanui te mea tino noa mō ngā whakaurunga whare noho, nā te mea ka whakamahia e rātou te wāhi tuanui kāore i te whakamahia. Ko ngā pūnaha e whakairihia ana ki te whenua ka whakamahia i ngā whakaurunga nui ake ina he iti te wāhi tuanui, ina pai ake rānei te whiti o te rā ki te whenua i te wāhi tāutanga.
6. Waea me ngā Wāhanga Hiko
Mā ngā waea me ngā wāhanga hiko e hono ngā wāhanga katoa o te pūnaha rā. Mai i ngā panera rā ki te inverter, te kaiwhakahaere utu, me te rokiroki pākahiko (mēnā e tika ana), me hono katoa ngā mea kia pai ai te mahi. He mea nui ngā taura me ngā hononga kounga teitei, ātete ki te huarere, mō te pai me te haumaru o te pūnaha.
He mea nui ngā wāhanga hiko tika, tae atu ki ngā kaiwawao hiko me ngā momotu, hei tiaki i te pūnaha mai i ngā hapa hiko, i ngā taumaha rawa rānei. Mā ēnei mahi haumaru ka noho haumaru te pūnaha, ā, ka taea te whakaweto ngāwari mō te tiaki, mō te wā ohorere rānei.
7. Pūnaha Aroturuki
A pūnaha aroturukihe wāhanga whiriwhiri engari he tino taunakihia mō tō tatūnga hiko o te rā. Mā ēnei pūnaha ka taea e koe te aroturuki i te mahi a tō pūnaha hiko o te rā i te wā tūturu, ka hoatu he māramatanga ki te nui o te pūngao e whakaputaina ana e tō pūnaha, te nui o te pūngao e pau ana i a koe, me te nui o te pūngao taikaha e rongoatia ana, e tukuna ana rānei ki te whatunga hiko.
Ka taea te uru atu ki ngā pūnaha aroturuki mā roto i ngā taupānga waea atamai, mā roto rānei i ngā tomokanga tukutuku, ā, ka taea e koe te aroturuki i te mahi a tō pūnaha mai i tawhiti. Ka taea hoki e ētahi pūnaha aroturuki te whakatūpato i a koe mō ngā take pea, pērā i te ngoikore o te mahi, ngā hiahia tiaki rānei, ā, ka āwhina i a koe kia pai tonu te whakahaere o tō pūnaha.
He maha ngā wāhanga nui o te pūnaha hiko o te rā e mahi tahi ana hei whakaputa, hei huri, hei penapena hoki i te hiko o te rā. Mai i ngā panera hiko e hopu ana i te hihi o te rā ki te kaitahuri hiko e huri ana i te hiko, he mea nui ia wāhanga hei whakarite kia pai te mahi a tō pūnaha, kia pono hoki te whakarato hiko.
Ahakoa kei te hiahia koe ki te whakaiti i ō pire hiko, ki te whai wāhi atu ki tētahi taiao matomato, ki te whakanui ake rānei i tō mana motuhake ki te pūngao, mā te mārama ki ngā wāhanga matua o tētahi pūnaha hiko o te rā koe e āwhina ki te whakatau whai whakaaro mō ō hiahia pūngao.
