1. Kaupapa Kaupapa

Kei roto i tēnei kaupapa te whakatinanatanga o tētahi pūnaha whakauru rokiroki-whakaahua AC-honohono ki te toa hokohoko 4S a tētahi kiritaki i Cambodia. Kei roto ko tētahi kaitahuri photovoltaic 125kW me tētahi pūnaha rokiroki pūngao hou kua tāpirihia, e āhei ai ngā mahi rua: 'te whakaputa-ake-ake mō te whakamahi-ake-ake me te whāngai-tāpua ki te whatunga hiko' me te 'mana tārua i waho o te whatunga hiko'. Ka aro katoa te hoahoa pūnaha ki ngā tauira whakamahinga hiko a te kiritaki (te whakamahinga toharite o ia rā tata ki te 14.8kWh, ngā hāora whakahaere 8:00–20:00) ā, ka tautoko i te hoko atu ki te 15kWh o te hiko tāpua ki te whatunga hiko i ia rā.

2. Nga taipitopito kaupapa

Taupānga

E rua ngā momo mahi a te pūnaha:

Aratau hono-Matiti:

– Ko te mana photovoltaic te mea nui mō ngā kawenga awatea;

– Ko ngā pākahiko rokiroki utu whakaputa PV nui rawa ka tuatahi;

– Kia kī tonu te pākahiko, ka taea te hoko atu i te hiko PV tāpiri ki te whatunga hiko (ka herea ki te 15kWh/rā);

I te pō, i te rangi pōuri rānei, ka tukuna te hiko e te tukunga pākahiko kia heke rā anō te SOC ki raro iho i te 10%, ā, i taua wā ka kati te pūnaha ka huri ki te pūtake hiko matua;

Kāore e whakaaetia te utu i ngā pākahiko mai i te pūtake hiko.

Aratau Tūtatari i Waho-Whatunga:

I te wā e motu ana te hiko matua, ka huri aunoa te pūnaha rokiroki hiko ki te mahi kore-pūnaha hei whakarato i ngā kawenga nui;

Ka kati te pūnaha ina tae te tukunga pākahiko ki te SOC < 10%, ka mutu ka momotu te kawenga.

3. Nga Painga Kaupapa

Arotau Ōhanga: Whakanuia te whakaputa hiko me te whakamahi hiko anō hei whakaiti i te whakapaunga hiko; tautokona te whāngai moni tāpiri o ia rā hei whiwhi moni tāpiri.

Haumarutanga Pūngao: Ka whakarato i te hiko tārua i waho o te whatunga i te wā e motu ana te hiko matua, kia taea ai te whakahaere poto i ngā kawenga nui.

Whakaritenga Maamaa: Ka huri aunoa i ngā rautaki utu/tuku i runga i ngā paepae SOC (10%–100%) hei whakaroa i te roa o te ora o te pākahiko.

Hototahi Teitei: Mā ngā atanga whakawhitiwhiti kōrero paerewa kua rāhuitia ka taea te whakauru atu ki ngā pūnaha PV o nāianei me ngā taputapu ine whatunga.

Urutau ā-Rohe: He arorau whakahaere kua whakaritea kia rite ki te iti o te whakamahinga hiko toharite o ia rā a ngā kiritaki (tata ki te 14.8kWh) me ngā hāora whakahaere, kia kore ai e nui rawa te whakarato.
